## Abstract

A leaning vehicle includes a vehicle body, a left front wheel, a right front wheel, a lean mechanism, a lean brake mechanism, a steering handle, a left grip, a throttle grip, a lean brake manipulator. The lean mechanism causes the left front wheel and the right 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. The lean brake mechanism brakes the leaning operation by the lean mechanism while the leaning vehicle is traveling. The lean brake manipulator is positioned at a first side in the vehicle width direction, changes a position integrally with the left grip, and for performing an operation of actuating the lean brake mechanism to brake.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

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;
a lean brake mechanism configured to brake a leaning operation of the lean mechanism;
a steering handle;
a first grip attached to the first side in the vehicle width direction of the steering handle;
a second grip attached to the second side in the vehicle width direction of the steering handle and performing a throttle operation; and
a lean brake manipulator positioned at the first side in the vehicle width direction, changes the position integrally with the first grip, and performing an operation of actuating the lean brake mechanism to brake.

### Claim 11 (depends on 10)

The leaning vehicle according to claim 10, wherein the lean brake manipulator is positioned closer to a center of the vehicle in the vehicle width direction than a center of the first grip in the vehicle width direction.

### Claim 12 (depends on 11)

The leaning vehicle according to claim 11, wherein the lean brake manipulator is positioned lower than the first grip.

### Claim 13 (depends on 12)

The leaning vehicle according to claim 12, wherein the lean brake manipulator can change position between at least a standby position and an operating position which is forward than the standby position and for actuating a lean brake.

### Claim 14 (depends on 10)

The leaning vehicle according to claim 10, further comprising:
a handle switch case positioned inner side of the first grip in the vehicle width direction and has a plurality of switches,
wherein the lean brake manipulator is disposed at a position that is different from the handle switch case.

### Claim 15 (depends on 10)

The leaning vehicle according to claim 10, wherein the lean brake manipulator changes its position or its attitude in accordance with an applied manipulation, and wherein a braking force of the lean brake mechanism changes in accordance with the position or the attitude of the lean brake manipulator.

### Claim 16 (depends on 15)

The leaning vehicle according to claim 15, wherein the lean brake manipulator is an auto-return type in which the position or the attitude of the lean brake manipulator changes by being applied a manipulating force and the lean brake manipulator returns an original position when the manipulating force is no longer applied.

### Claim 17 (depends on 10)

The leaning vehicle according to claim 10, wherein states of the lean brake manipulator is switched between an effective state and an ineffective state in accordance with a manipulation on the lean brake manipulator, and wherein when the lean brake manipulator is in the effective state, the lean brake mechanism brakes the leaning operation with fixed degree of the braking force, and when the lean brake manipulator is in the ineffective state, the lean brake mechanism does not brake the leaning operation.

### Claim 18 (depends on 10)

The leaning vehicle according to claim 10, further comprising:
a control device controlling the lean brake mechanism,
wherein the control device actuates the lean brake mechanism to brake the leaning operation when the control device determines that an occurrence condition is met.
