When the sub-groove in the first panel portion is designated as the first sub-groove, the optical path as the first optical path, and the through-hole as the first through-hole, The second panel portion has a second sub-groove portion that opens on the inner surface and is connected to the end of the first sub-groove portion in the vehicle width direction, and extends rearward in the front-rear direction from the end. The second sub-groove portion has a second optical path for light emitted from the light source, The vehicle interior ventilation structure according to claim 6, wherein the portion of the inner surface of the second panel portion in which the second sub-groove portion is open constitutes the second light transmission opening.

Description

This invention relates to an in-vehicle ventilation structure for supplying conditioned air to the vehicle interior. Patent Document 1 describes one form of an in-vehicle ventilation structure. An instrument panel extending in the vehicle width direction is positioned adjacent to the front of the vehicle in relation to the passenger compartment. A pair of side doors are positioned adjacent to both sides of the passenger compartment in the vehicle width direction. An air outlet for conditioned air is provided at the end of the instrument panel in the vehicle width direction. The air outlet has a long, narrow rectangular shape in the vehicle width direction. The conditioned air is blown into the passenger compartment from this air outlet. Each side door houses a partition member, stored in a retracted state by a winding mechanism. The door trim of the side door has an opening for pulling out the partition member. The opening is a long, narrow rectangle in the front-to-back direction. The partition member is then pulled out through the opening and unfolded inside the vehicle. This unfolded partition divides the space in front of the occupants seated in the vehicle seats vertically. Therefore, conditioned air can be concentrated and retained around the occupants' upper or lower bodies, improving the efficiency of the vehicle's air conditioning. Japanese Patent Publication No. 2010-13063 This is a partial perspective view showing the main parts of the in-vehicle ventilation structure in one embodiment.This is a partial plan view showing the main parts of the vehicle interior ventilation structure in the above embodiment. An embodiment of the in-vehicle ventilation structure will be described below with reference to Figures 1 and 2. In the following description, the forward direction of vehicle 10 will be referred to as "front," and the reverse direction as "rear." The vertical direction refers to the vertical direction of vehicle 10, and the left-right direction refers to the vehicle width direction, which coincides with the left-right direction when vehicle 10 is moving forward. The vehicle 10 is equipped with a passenger compartment 11. A vehicle seat 12 is arranged inside the passenger compartment 11. The vehicle seat 12 is not shown in Figure 2. <First panel section P1 and second panel section P2> A first panel section P1 extending in the left-right direction is positioned adjacent to the front of the passenger compartment 11. The first panel section P1 comprises a plurality of first panel components. The rear surface of the first panel section P1 faces the passenger compartment 11. A pair of second panel sections P2 extending in the front-rear direction are positioned adjacent to both sides of the passenger compartment 11 in the left-right direction. The pair of second panel sections P2 sandwich the passenger compartment 11 from both the left and right sides. The inner surfaces of each of the pair of second panel sections P2 face the passenger compartment 11. Each second panel section P2 comprises a plurality of second panel components. The first and second panel components will be described later. The entirety of the first panel section P1 and the front portions of each of the pair of second panel sections P2 are equipped with a toe board 15 and two types of cowls 21 and 25. <Toeboard 15> The toe board 15 is a plate-shaped member that separates the passenger compartment 11 from the portion of the vehicle 10 in front of the passenger compartment 11, for example, the engine compartment (not shown). The toe board 15 is where the feet of an occupant seated in the vehicle seat 12 are placed. The toe board 15 comprises a front plate portion 16, a pair of side plate portions 17, and an upper plate portion 18. The front plate portion 16 is inclined with respect to both a horizontal and a vertical plane (neither of which is shown) such that the upper part is positioned further forward on the front side of the passenger compartment 11. The right side panel 17 extends rearward from the right end of the front panel 16. The upper surface of the right side panel 17 extends approximately horizontally rearward from the upper right end of the front panel 16. The rear surface of the right side panel 17 is inclined with respect to the horizontal and vertical planes, with the upper part positioned further forward. In contrast, the left side panel 17 is formed to be symmetrical with respect to the right side panel 17. The majority of the upper plate portion 18 extends forward from the upper end of the front plate portion 16. The right end of the upper plate portion 18 is formed on at least the upper front end of the right side plate portion 17. Conversely, the left end of the upper plate portion 18 is formed on at least the upper front end of the left side plate portion 17. <Cowl 21, 25> One cowl 21 is positioned above the toe board 15. The cowl 21 comprises a front plate portion 22 and a pair of side plate portions 23. The fr
