[0076] According to the seat 1 according to the embodiment, since the horizontal wire 3 is arranged near the ischium of the occupant, the top plate 2 can efficiently support the load of the occupant. Therefore, in the seat 1 of the saddle-riding type vehicle having the top plate 2 forming the seating surface 2A, the occupant can be supported with good stability.

[0077] Since the frame 6 imparts rigidity to the edge portion of the top plate 2, the top plate 2 can maintain its shape. Further, since the horizontal wire 3 and the left and right rear wires 5 are connected to the frame 6, the horizontal wire 3 and the left and right rear wires 5 can support the occupant with good stability.

[0078] Since the vertical wire 4 penetrates the bottom plate 7 and the top plate 2 is supported by the bottom plate 7 and the vertical wire 4, the top plate 2 can stably support the occupant.

[0079] With the above description of the specific embodiments completed, the present invention can be widely modified and implemented without being limited to the above embodiments. For example, the top plate 2 and the frame 6 may be integrally formed by two-color molding. In this case, as shown in FIG. 20, the connecting portion 6D protruding upward from the frame 6 may be inseparably connected to the ventilation holes 11 by passing through some ventilation holes 11 and turning around to the upper surface of the top plate 2. By these, the displacement between the frame 6 and the top plate 2 is suppressed, and the top plate 2 is reliably supported by the frame 6.
