Abstract:
A leaning vehicle includes a vehicle body; a rear wheel; a left arm mechanism; a left steerable front wheel; a right arm mechanism; a right steerable front wheel; a leaning mechanism; a leaning drive mechanism; and a steering mechanism. The leaning drive mechanism is disposed between any one of a left-right arm connection mechanism, the left arm mechanism and the right arm mechanism and the vehicle body. A rear end of the leaning drive mechanism is disposed at a rear side of a lower end of a steering shaft in the front-back direction of the vehicle body. A front end of the leaning drive mechanism is disposed at a front side of an upper end of the steering shaft. At least a portion of the leaning drive mechanism is disposed at a down side of the steering shaft in the up-down direction of the vehicle body.

Claim (Index 1):
A leaning vehicle, comprising:\n a vehicle body capable of leaning in a left-right direction of the leaning vehicle; a rear wheel supported by the vehicle body; a left arm mechanism that is disposed at a left side of the vehicle body in the left-right direction of the vehicle body, that has a right portion that is supported by the vehicle body in a swingable manner in an up-down direction of the vehicle body corresponding to a lean of the vehicle body, and that has a left portion; a left steerable front wheel that is disposed at a front side of the rear wheel in a front-back direction of the vehicle body, and that is steerably supported by the left portion of the left arm mechanism; a right arm mechanism that is disposed at a right side of the vehicle body in the left-right direction of the vehicle body, that has a left portion that is supported by the vehicle body in a swingable manner in the up-down direction of the vehicle body corresponding to a lean of the vehicle body, and that has a right portion; a right steerable front wheel disposed at the front side of the rear wheel in the front-back direction of the vehicle body, and steerably supported by the right portion of the right arm mechanism; a leaning mechanism that includes a left-right arm connection mechanism which connects the left arm mechanism and the right arm mechanism with each other, and which has a damping action for damping swinging of the left arm mechanism and the right arm mechanism in the up-down direction of the vehicle body, that causes the vehicle body, the left steerable front wheel and the right steerable front wheel to lean leftward of the vehicle with turning of the vehicle to the left, and that causes the vehicle body, the left steerable front wheel and the right steerable front wheel to lean rightward of the vehicle with turning of the vehicle to the right; a leaning drive mechanism that is disposed at a center portion of the vehicle body in the left-right direction, that is disposed between any one of the left-right arm connection mechanism, the left arm mechanism or the right arm mechanism and the vehicle body, and that is configured to apply a swinging force which causes the left arm mechanism and the right arm mechanism to swing in the up-down direction of the vehicle body; and a steering mechanism including a steering shaft that is rotatably supported by the vehicle body; a rotary member that is disposed at a lower portion of the steering shaft and that rotates together with the steering shaft; and a tie rod that is mounted on the rotary member and that is configured to be displaceable in the left-right direction of the vehicle body, the steering mechanism causing the left steerable front wheel and the right steerable front wheel to be steered with the rotation of the steering shaft, wherein the steering shaft is disposed at the center portion of the vehicle body in the left-right direction, and has an upper end and a lower end, the lower end of the steering shaft being disposed at a front side of the upper end of the steering shaft in the front-back direction of the vehicle body, and the upper end of the steering shaft being disposed at a rear side of a rear end of the right portion of the left arm mechanism and a rear end of the left portion of the right arm mechanism in the front-back direction of the vehicle body, wherein the lower end of the steering shaft is disposed at a rear side of a front end of the right portion of the left arm mechanism and a front end of the left portion of the right arm mechanism in the front-back direction of the vehicle body, and the lower end of the steering shaft is disposed at a front side of a rear end of the right portion of the left arm mechanism and a rear end of the left portion of the right arm mechanism in the front-back direction of the vehicle body, and wherein the leaning drive mechanism is disposed at the center portion of the vehicle body in the left-right direction, has a rear end that is disposed at a rear side of the lower end of the steering shaft in the front-back direction of the vehicle body, and has a front end that is disposed at a front side of the upper end of the steering shaft in the front-back direction of the vehicle body, and at least a portion of the leaning drive mechanism is disposed at a down side of the steering shaft in the up-down direction of the vehicle body.
