Claims (6)

1. 1 . A spinning reel for fishing that has a reel body and configured to cast fishing line in a forward direction, comprising: a spool shaft configured to be movable in the reel body; a spool having a bobbin trunk around which fishing line is capable of being wound and rotatably supported by the spool shaft; and a first drag mechanism having a first drag washer disposed forward of the bobbin trunk and configured to brake rotation of the spool, at least a portion of the first drag washer being disposed radially farther from the spool shaft than a surface of the bobbin trunk on which the fishing line is to be wound.
2. 2 . The spinning reel for fishing according to claim 1 , wherein the first drag washer is disposed on a front end surface of the bobbin trunk.
3. 3 . The spinning reel for fishing according to claim 1 , comprising a second drag mechanism that has a second drag washer disposed rearward of the bobbin trunk and configured to brake the rotation of the spool.
4. 4 . The spinning reel for fishing according to claim 3 , further comprising a drag knob configured to adjust a pressing force on the first drag washer or the second drag washer.
5. 5 . The spinning reel for fishing according to claim 3 , further comprising a drag knob configured to adjust a pressing force on the first drag washer and on the second drag washer at the same time.
6. 6 . The spinning reel for fishing according to claim 1 , wherein the first drag washer is disposed so the at least a portion of the first drag washer is disposed radially farther from the spool than at least a portion of a flange of the bobbin trunk.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Japanese Patent Application No. 2023-095076, filed on Jun. 8, 2023. The entire disclosure of Japanese Patent Application No. 2023-095076 are hereby incorporated by reference. BACKGROUND Technical Field The present disclosure relates to a spinning reel for fishing. Background Information Conventional spinning reels for fishing can cast fishing line in a forward direction and are generally equipped a reel body, a spool shaft that is movable relative to the reel body, a spool with a bobbin trunk onto which fishing line can be wound and which is rotatably supported by the spool shaft, and a drag mechanism that is disposed within the bobbin trunk. See for example, see Japanese Patent Publication No. 2021-122176. SUMMARY It has been determined that in the spinning reel for fishing described in Japanese Patent Publication No. 2021-122176, when the drag washer of the drag mechanism is disposed inside the bobbin trunk, the drag washer becomes hot due to the heat generated by the drag operation, and there is the risk that the fishing line wound around the bobbin trunk will deteriorate due to the heat. Further, in the case of the prior art, since the space inside the bobbin trunk is narrow, the outer diameter of the drag washer is restricted, resulting in increased surface pressure, which causes durability problems. The present disclosure was made in consideration of these circumstances, and the object thereof is to provide a spinning reel for fishing which can prevent the deterioration of fishing line due to the heat generated during a drag operation and which can enhance the durability of the drag washer. A first aspect of the spinning reel for fishing according to the present disclosure concerns a spinning reel for fishing that can cast (throw out) fishing line in a forward direction and that comprises a reel body, a spool shaft that is movable relative to the reel body, a spool rotatably supported by the spool shaft and with a bobbin trunk onto which fishing line can be wound, and a first drag mechanism, which has a first drag washer disposed forward of the bobbin trunk and which can brake the rotation of the spool. According to the first aspect of the spinning reel for fishing of the present disclosure, the first drag mechanism with the first drag washer is disposed forward of the front end of the bobbin trunk of the spool, which enables the outer diameter of the first drag washer to be larger than in the case of the prior art, in which the drag mechanism is disposed inside the bobbin trunk. Therefore, the drag contact area of the first drag washer can be increased, and the surface pressure applied to the first drag washer can be minimized, thereby enhancing drag durability. Further, in the present disclosure, by disposing the first drag mechanism at a position forward of and away from the bobbin trunk, it is possible to prevent the deterioration of the fishing line wound around the bobbin trunk due to the heat generated by the drag operation. Further, since the heat generated in the bobbin trunk due to a drag operation can be minimized in this way, the wall thickness of the bobbin trunk, which was increased in the prior art in consideration of the conducted heat, can be thinner, and, as a result, the weight of the spool can be reduced. According to a second aspect of the present disclosure, in the spinning reel for fishing according to the first aspect, the first drag washer is preferably disposed on a front end surface of the bobbin trunk. In this embodiment, since the first drag washer is disposed on the front end surface of the bobbin trunk, the heat generated by the drag operation is more easily dissipated and the deterioration of the fishing line can be reduced, compared to a case in which the drag washer is disposed in a space in which heat accumulates, such as inside the bobbin trunk. Further, in the present disclosure, the first drag washer can be held by using the space forward of the bobbin trunk, so that, compared to a case in which the drag washer is placed inside the bobbin trunk, the holding structure of the first drag washer can be simplified and the weight of the spool can be reduced. According to a third aspect of the present disclosure, in the spinning reel for fishing according to the first or second aspect, it is preferable to have a second drag mechanism with a second drag washer, which device is installed rearward of the bobbin trunk and brakes the rotation of the spool. In this embodiment, the first drag mechanism and the second drag mechanism can be respectively positioned forward of and rearward of the bobbin trunk, so that the first drag washer and the second drag washer can each be of larger outer diameter. Therefore, the drag contact area of both the first and second drag washers can be increased, and the surface pressure applied to the first and second drag washers can be minimized, thereby enhancing drag dur
