Abstract: A dimmer switch includes a main body and an operation portion. The operation portion is provided in the main body to be rotatable around a rotation axis to switch the dimmer switch among an off position, a low beam position, and a high beam position. The low beam position and the high beam position are provided above a horizontal line passing through the rotation axis and the off position is provided below the horizontal line in a state where the dimmer switch is attached to a vehicle body. A first rotation angle between the off position and the low beam position is set to be larger than a second rotation angle between the low beam position and the high beam position.

Support shafts are provided in the lamp housing and are supported in a light cover. In the light-device mounting structure, the support shafts are covered with support-shaft protective members. The support-shaft protective members are engaged non-rotatably relative to the support shafts. The light cover has fitting holes, and the support shafts are fitted into the fitting holes through the support-shaft protective members.

Abstract: In a vehicle having a vehicle body frame from which left and right front wheels are suspended, a winch is mounted so as to be disposed between the front wheels and configured to appropriately wire a plurality of conductors to a contactor interposed between the winch and a battery. Winch positive and negative side terminals, a battery positive side terminal and a grounding negative side terminal are disposed in a concentrated manner on a terminal disposition face of the contactor. Winch positive and negative side conductors extend from the contactor to the winch side. A battery positive side conductor and a grounding conductor extend from the contactor in directions different from the extending direction of the winch positive and negative side conductors from the contactor and different from each other.

Abstract: A seat supporting member designed to support, from below, a seat member in its closed position, is provided on a body frame for allowing the seat member to be attached to and detached from the seat supporting member. A rear part of the seat member and an intermediate part of the seat supporting member in a front-rear direction thereof are connected to each other via a swinging arm. The seat member is supported on a body frame while its position is variable between a closed position where the seat member allows an occupant to sit thereon while covering at least one of maintenance spaces and a housing space from above; and an open position where an upper opening of the at least one of the maintenance spaces and the housing space is widely, almost completely opened.

Abstract: A front wheel differential lock control system for a straddle-ride type four-wheeled vehicle is provided that can reliably switch a differential locking mechanism into a lock state in a low vehicle-speed state. In an engine provided with a manual transmission having forward five-speed and reverse gears, only in a low gear ratio state (1st through 3rd gears) is actuation of a diff-lock actuator permitted to switch a front wheel differential mechanism into a differential lock state. When a diff-lock operation is operated on the time of selection of third-, fourth- or fifth-speed gear, engine rotation number control is exercised to allow an engine rotation number to converge on a predetermined upper limit value. In an engine provided with a start clutch or a torque converter, actuation of the diff-lock actuator is permitted only in a low engine rotation number state where drive force is not transmitted to the front wheels.

Abstract: A strut suspension is disposed on a vehicle front side of a rotation center of a front wheel. A rack and pinion mechanism is disposed on a vehicle front side of the strut suspension. Since the strut suspension and the rack and pinion mechanism are disposed on the vehicle front side of the rotation center of the front wheel, a foot space can be moved forward to a position where the foot space overlaps the front wheel. A vehicle cabin space can be thereby increased.

Abstract: A saddle-ride type vehicle, and arrangement of an electric part such as a controller for a saddle-ride type vehicle, can include a vehicle frame which has a left main frame and a right main frame which extend from a forward side to a rearward side of a vehicle body. An engine is supported on the vehicle frame, and a throttle body is disposed near the engine. An air cleaner is disposed adjacent throttle body, and a controller is provided, which is configured to control the engine. A support member supports at least a controller, with the support member being removably mounted relative to the vehicle body. The support member is separate from the throttle body and the air cleaner. The support member is typically disposed above the throttle body.

Abstract: A strut suspension is disposed on a vehicle front side of a rotation center of a front wheel. A rack and pinion mechanism is disposed on a vehicle front side of the strut suspension. Since the strut suspension and the rack and pinion mechanism are disposed on the vehicle front side of the rotation center of the front wheel, a foot space can be moved forward to a position where the foot space overlaps the front wheel. A vehicle cabin space can be thereby increased.

Abstract: The vehicle body frame is configured in a manner that an upper tension pipe is removed from a first cross portion and a second cross portion. When mounting the engine in the vehicle body frame, the vehicle mounted component that is relatively heavy can be lowered into the vehicle body frame from above by removing the upper tension pipe. The vehicle body frame simplifies the removal and installation of the vehicle-mounted components.

Abstract: An air cleaner apparatus includes a lid that covers an opening formed in an air cleaner box is provided with an intake port communicating with the opening. In addition, a regulator is attached to an upper wall portion of the air cleaner box, the intake port is extended to the upper wall portion of the air cleaner box so as to cover the regulator, and the regulator is placed facing inside an intake passage connecting between the intake port and the opening. The air cleaner apparatus so configured provides a sufficient cooling effect, and is excellent in ease of maintenance.
