Further, the base portions 78a and 78a of the projections 78 and 78 do not contact the upper surface of the connection plate 90, and the vertical load of the main seat 45 is applied to other portions such as the contact portions 80 and 81 of the seat bottom plate 70. I can receive it.

12 is an enlarged view of the periphery of the connection plate 90 in FIG. 13 is a sectional view taken along line XIII-XIII in FIG.
As shown in FIGS. 12 and 13, when the main seat 45 is attached, the positioning projections 78 b and 78 b in the substantially positive direction in plan view are such that the outer surfaces 102 and 102 on the outer side in the vehicle width direction are outside the positioning opening 94. It contacts the edges 94a, 94a. Thereby, since the seat front portion 45b is positioned in the vehicle width direction and the movement in the vehicle width direction is restricted, even if the distance from the catch mechanism portion 83 to the arm portions 74 and 74 is large, It can suppress effectively that the peripheral part of the arm parts 74 and 74 opens with respect to the center side covers 49L and 49R.
Further, since the opening of the main seat 45 can be suppressed by the positioning protrusions 78b and 78b, the catch mechanism portion 83 can be arranged further rearward. Thereby, it is possible to prevent the catch mechanism 83 from interfering with the arrangement of other parts such as the fuel tank 41, and thus the degree of freedom of the arrangement of the parts can be improved.

  In addition, since the stay portions 99, 99 of the center side covers 49L, 49R are fixed to the connection plates 90, 90 provided with the positioning openings 94, the center side covers 49L, 49R are highly accurate with respect to the main seat 45. It can position and can suppress that the main seat 45 and the center side covers 49L and 49R open. Furthermore, it is not necessary to provide a separate member for fixing the center side covers 49L and 49R, and the number of parts can be reduced.

In plan view, the positioning protrusions 78b and 78b are formed in a substantially square shape that is shorter in the front-rear and left-right directions than the substantially rectangular positioning openings 94 and 94. As a result, the positioning projections 78b and 78b are not in contact with the positioning openings 94 and 94 except for the side surfaces other than the outer surfaces 102 and 102, and between the other side surfaces and the peripheral portions of the positioning openings 94 and 94. The escape is formed. For this reason, the positioning protrusions 78b and 78b can be properly fitted to the positioning opening 94 without strictly managing the dimensional accuracy of the positioning opening 94 and the positioning protrusions 78b and 78b.
Further, two corners on the outer peripheral side of the peripheral edge of the positioning opening 94 are formed as substantially right-angled corners, and long linear outer edges 94a and 94a and outer surfaces 102 and 102 of the positioning projections 78b and 78b, Since the surface is brought into contact with the surface, the load acting on the contact portion can be dispersed.
