A vehicle includes a center transmission plate, a first center turnable portion configured to turn about a first center turning axis extending in an up-down direction, a second center turnable portion configured to turn about a second center turning axis extending in a front-rear direction, a left transmission plate, a first left turnable portion configured to turn about a first left turning axis extending in the up-down direction, a second left turnable portion configured to turn about a second left turning axis extending in the front-rear direction, a right transmission plate, a first right turnable portion configured to turn about a first right turning axis extending in the up-down direction, and a second right turnable portion configured to turn about a second right turning axis extending in the front-rear direction. A tie rod is supported on the second center turnable portion, the second left turnable portion, and the second right turnable portion.

Vehicle

At least a portion of a tie rod of a steering force transmitting mechanism overlaps with a portion of a first support member or a second support member when viewed from a front of a vehicle in a fully-tilted condition in which the vehicle body frame is fully tilted in the left-right direction. At least a portion of the tie rod is disposed below a second cross member, above a first front wheel and a second front wheel, behind a front end of the first front wheel and a front end of the second front wheel, and ahead of a first axis of a first side member and a second axis of a second side member when viewed from the left or right of the vehicle when the vehicle body frame is in an upright state.

A transformation restricting mechanism is configured to change a resisting force between a first connecting member, a second connecting member, and a caliper that are configured to be displaced relative to each other. The first connecting member includes a turn supporting portion supported by a first shock absorbing device. The second connecting member includes a turn supporting portion supported by a second shock absorbing device. The turn supporting portion is supported by the first shock absorbing device closer to a first center axis than an intermediate axis which is coincident with a turning axis of a steering shaft when the vehicle body frame is in an upright state. The turn supporting portion is supported by the second shock absorbing device closer to a second center axis than the intermediate axis when the vehicle body frame is in an upright state.

A vehicle includes a stop element supported on a first support portion which is provided on any one of a link mechanism, a body frame, a right shock absorbing device, and a left shock absorbing device at a first end portion thereof so as to turn about a support axis of the first support portion, a lock caliper supported on a second support portion which is displaced relative to the first support portion and which is provided on any one of the link mechanism, the body frame, the right shock absorbing device, and the left shock absorbing device and which is configured to change a frictional force with the stop element, and a guide member which guides a middle portion or a second end portion of the extended member to the lock caliper. A turning angle of the stop element relative to the first support portion based on a turning operation of a first cross member and a second cross member relative to the body frame is smaller than a turning angle of the first cross member or a turning angle of the second cross member relative to the body frame based on the turning operation.
