  • Patent number: 11975795
    Abstract: A leaning vehicle includes a vehicle body, a plurality of wheels, a lean mechanism, and a lean stopper mechanism. The wheels include a left front wheel and a right front wheel. 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 stopper mechanism prevents a lean angle from exceeding a limit angle. in a plan view, an area bounded by lines connecting contact positions of ground and tires of the plurality of wheels is referred to as a grounding surface inner area, and a gravity center is positioned in the grounding surface inner area in a state where the lean angle reaches the limit angle.

  • Patent number: 11926388
    Abstract: A leaning vehicle includes a vehicle body, a left front wheel, a right front wheel, a lean mechanism, and a lean brake mechanism. 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 a leaning operation of the lean mechanism. The lean brake mechanism includes a brake caliper and a brake disc. The brake caliper is attached to the lean mechanism and has a brake pad. The brake disc is attached to the lower arm of the upper arm and the lower arm that is farther from the brake pad in the front view, has a contact portion that generates braking force by being pressed by the brake pad.

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 a leaning operation of the lean mechanism. The lean brake mechanism includes a brake disc and brake pads. The brake disc is attached to an upper arm or a lower arm. The brake pads, which are attached such that their position relative to the brake disc changes in the leaning operation, produce a frictional force against the brake disc in the leaning operation.

  • Patent number: 9904130
    Abstract: There are provided connecting wires whose reliability may be ensured by preventing leakage between the connecting wires and by preventing entry of moisture. Overexposure is performed by using a mask having a shape of a protruding pattern (55a) with a sharp tip end at a position corresponding to a pattern edge of an organic insulating film (70) between adjacent connecting wires (50). Inclination of an inclined surface of the organic insulating film (70) sandwiched by the connecting wires (50) is thereby made gradual, and thus, at the time of forming the connecting wires (50), a film thickness of a resist may be prevented from becoming thick along an edge line of the organic insulating film (70). As a result, the resist is prevented from remaining in a connected manner at a region sandwiched by the adjacent connecting wires (50), and leakage between the adjacent connecting wires (50) may be prevented.
