In the present invention, a resistance changing mechanism (7) includes a first section (11) and a second section (12) that allow resistance to be changed in accordance with displacement of the relative positions thereof. The first section (11) is supported by one member among any of a first side member (53), second side member (54), first cross member (51), and second cross member (52) of a linking mechanism (5). When viewed from the direction of an upper intermediate axis, the first section (11) is placed at a position where the first section at least partially overlaps with the one member at all times. The first section (11) is provided in front of the one member and a steering shaft (60) in terms of the direction of the upper intermediate axis. The second section (12) is supported by one other member, among a vehicle frame (21), the first side member (53), the second side member (54), the first cross member (51), and the second cross member (52), that is displaced relative to the one member by which the first section (11) is supported. When viewed from the direction of the upper intermediate axis, the second section (12) is placed at a position where the second section at least partially overlaps with the one other member at all times. The second section (12) is provided side by side the one other member in front of the one member for the first section (11) and the steering shaft (60). |
