Hereinafter, embodiments of the present invention will be described with reference to Figures 1 to 8D. This embodiment relates to a vehicle seat equipped with a seat frame, wherein the seat frame comprises side frames arranged on the left and right sides in the seat width direction, and a connecting frame connecting the left and right side frames, and the side frames have engaging portions that engage with engaged portions provided on the connecting frame to position the connecting frame, and one of the engaging portion and the engaged portion protrudes toward the other, and the other portion engages with the one by abutting toward the one. In vehicle seating, the side of the seat back that the occupant sits on is considered the front of the seat. As shown in Figure 1, the vehicle seat S of this embodiment is a vehicle seat and mainly consists of a seat body comprising a seat back 1 and a seat cushion 2, a rail device 3 that supports the seat body so as to be movable forward and backward relative to the vehicle floor as shown in Figure 2, a height link device 4 that connects the seat body to the vehicle floor so as to be able to move up and down, and a reclining device 5 that rotatably connects the seat back 1 to the seat cushion 2. As shown in Figure 1, the seat back 1 is a backrest that supports the occupant from behind, and is constructed by placing a pad material 1a on a back frame 10, which is the skeleton shown in Figure 2, and covering it with a surface material 1b. The seat cushion 2 is a seating portion that supports the occupant from below, and is constructed by placing a pad material 2a on a cushion frame 20, which serves as the skeleton, as shown in Figure 2, and covering it with a surface material 2b. As shown in Figure 2, the rail device 3 is positioned between the seat body and the vehicle floor in the vertical direction and mainly consists of left and right lower rails 3a fixed to the vehicle floor and extending in the front-rear direction of the seat, left and right upper rails 3b supported so as to be slidable along the lower rails 3a, a locking member (not shown) that locks the upper rails 3b so as not to slide relative to the lower rails 3a, and a rail operating lever 3c for releasing the locked state of the locking member. Cushion frames 20 are installed on the upper surfaces of the left and right upper rails 3b via height link devices 4. As shown in Figure 2, the height link device 4 is mounted between the rail device 3 and the cushion frame 20 and mainly consists of left and right first links 4a positioned on the front side of the seat, left and right second links 4b positioned on the rear side of the seat, a locking member (not shown) that locks the seat body to prevent it from being raised or lowered, and a height adjustment lever (not shown) for releasing the lock of the locking member. The second links 4b act as drive links, allowing the height of the seat body to be adjusted. As shown in Figure 2, the reclining device 5 mainly consists of a reclining body 5a that is driven when the back frame 10 is rotated, a pivot shaft 5b, a spiral spring 5c that biases the back frame 10 to rotate forward around the pivot shaft 5b, and a reclining operation lever (not shown) that is operated to release the locked state of the back frame 10. The reclining body 5a has a known locking mechanism, which allows the state of the back frame 1
