## Abstract

An oil filter exposed to an outside of an internal combustion engine that may be damaged by a stone or a similar object thrown rearwardly from a front tire. A saddle-ride type vehicle includes a power unit that includes an internal combustion engine and a transmission. The transmission is coupled to the internal combustion engine. A lower portion of the power unit forms an oil reservoir. The power unit includes an oil filter, an actuator, and a transmission mechanism. The actuator is configured to drive the transmission. The transmission mechanism is configured to transmit power from the actuator to the transmission. The oil filter is disposed outside a wall portion of the power unit. The wall portion configures a part of the oil reservoir. The oil filter is disposed adjacent to the wall portion and the actuator.

## Claims

### Claim 1

An oil filter disposition structure of a saddle-ride vehicle comprising:
a power unit including an internal combustion engine and a transmission, the transmission being operatively coupled to the internal combustion engine, a lower portion of the power unit forming an oil reservoir;
wherein the power unit includes an oil filter, an actuator, and a transmission mechanism, the actuator being configured to drive the transmission, the transmission mechanism being configured to transmit power from the actuator to the transmission; and
the oil filter is disposed outside a wall portion of the power unit, the wall portion configuring a part of the oil reservoir, the oil filter being disposed adjacent to the wall portion and the actuator,
wherein said transmission mechanism is disposed between a front wheel of the saddle-ride vehicle and the oil filter, said actuator is disposed at a rear of the transmission mechanism, and said oil filter is disposed adjacent to a sidewall facing a vehicle lateral side;
an exhaust pipe operatively connected to the power unit, the exhaust pipe being coupled to the internal combustion engine, the exhaust pipe being disposed adjacent to the oil filter outwardly in a vehicle-width direction;
said transmission mechanism includes a plurality of gears, wherein the plurality of gears are configured to transmit a driving power from the actuator to the transmission, and
the plurality of the gears are disposed by orienting turning shaft lines of the plurality of gears in a vehicle front-rear direction.

### Claim 2 (depends on 1)

The oil filter disposition structure of the saddle-ride vehicle according to claim 1, wherein a part of the sidewall is formed as a bulge portion, the bulge portion bulging outwardly in a vehicle-width direction, and
the oil filter is disposed at a front of a front sidewall of the bulge portion, the oil filter being disposed adjacent to the front sidewall.

### Claim 3 (depends on 1)

The oil filter disposition structure of the saddle-ride vehicle according to claim 1, wherein the oil filter is mounted to an oil filter mounting portion wherein a portion of the oil filter is fitted within a recess providing a gap and the recess is formed at a front half portion of a left sidewall of a left crankcase half body.
