1. A leaning vehicle, comprising:
a vehicle body;
a first front wheel positioned on a first side in a vehicle width direction;
a second front wheel positioned on a second side opposite to the first side in the vehicle width direction;
a lean mechanism configured to cause the first front wheel and the second front wheel to lean about a front-rear direction as a rotation center when the vehicle body leans about the front-rear direction as a rotation center; and
a lean brake mechanism configured to brake a leaning operation of the lean mechanism,
wherein the lean mechanism includes:
an upper arm,
a lower arm positioned more downward than the upper arm,
a first arm attached to the first front wheel and rotatably attached to the upper and lower arms, and
a second arm attached to the second front wheel and rotatably attached to the upper and lower arms,
wherein the lean brake mechanism includes:
a first brake member attached to the upper arm or the lower arm, and
a second brake member attached such that its position relative to the first brake member changes in the leaning operation, the second brake member being configured to produce a frictional force against the first brake member in the leaning operation,
wherein if the upper arm is attached to the first brake member, the upper arm includes a fulcrum portion at its longitudinal center, the fulcrum portion being rotatably attached to a side body portion of the vehicle body,
wherein if the lower arm is attached to the first brake member, the lower arm includes a fulcrum portion at its longitudinal center, the fulcrum portion being rotatably attached to the side body portion of the vehicle body, and
wherein, in a side view, the first and second front wheels overlap with the lean mechanism.
