Abstract
A clutch device includes a clutch center holding an output-side rotating plate facing an input-side rotating plate and a plate presser pressing the input-side rotating plate or the output-side rotating plate. The clutch center includes a driven shaft coupling portion coupled with a tip portion of a shaft. The plate presser includes a center cylindrical portion including a center fitting portion slidably fitted to an outer surface of the driven shaft coupling portion and an oil receiver located adjacent to the center fitting portion to receive clutch oil flowing out of the tip portion of the shaft.
Claims25
A clutch device allowing or blocking transfer of a rotation driving force of a drive shaft to a driven shaft, the clutch device comprising:
- a clutch center including a plate holder holding an output-side rotating plate facing an input-side rotating plate rotationally drivable by rotational driving of the drive shaft, the clutch center being rotationally drivable together with the driven shaft;
- and
- a plate presser facing the clutch center and displaceable toward or away from the clutch center and rotatable with respect to the clutch center to press the input-side rotating plate or the output-side rotating plate;
- wherein
- the plate presser includes a center cylindrical portion;
- the clutch center includes a driven shaft coupling portion coupled with a tip portion of the driven shaft;
- and
- the center cylindrical portion includes a center fitting portion slidably fitted to the driven shaft coupling portion and a cylindrical oil receiver adjacent to the center fitting portion to receive clutch oil flowing out of a flow-out portion of the driven shaft.
A clutch device allowing or blocking transfer of a rotation driving force of a drive shaft to a driven shaft, the clutch device comprising:
- a clutch center including a plate holder holding an output-side rotating plate facing an input-side rotating plate rotationally drivable by rotational driving of the drive shaft, the clutch center being rotationally drivable together with the driven shaft;
- and
- a plate presser facing the clutch center and displaceable toward or away from the clutch center and rotatable with respect to the clutch center to press the input-side rotating plate or the output-side rotating plate;
- wherein
- the plate presser includes a center cylindrical portion;
- the clutch center includes a driven shaft coupling portion coupled with a tip portion of the driven shaft;
- and
- the center cylindrical portion includes a center fitting portion slidably fitted to the driven shaft coupling portion and a recessed portion provided in a portion of the plate presser in a circumferential direction in which the center fitting portion is provided, the recessed portion expanding diametrically outward and defining a gap between the recessed portion and an outer circumferential portion of the driven shaft coupling portion to enable clutch oil to flow out of a flow-out portion of the driven shaft and to flow into the recessed portion.
