- the oil inflow portion 5e constituting the flow passage may be formed on the opening side of the accommodating recess 5d, and the oil outflow portion 5g may be formed without passing through the groove portion 5f.
- the clutch member is not a split structure, is not provided with the centrifugal clutch means 9, and is applied to a structure in which a boss portion 4ac is formed so as to protrude inside the accommodating recess 5d.
- the oil inflow portion 5e and the oil outflow portion 5g may be formed in the accommodating recess 5d.
- the oil inflow portion 5e formed on the bottom side of the accommodating recess 5d instead of the oil inflow portion 5e formed on the bottom side of the accommodating recess 5d, as shown in FIGS. 24 to 26, the oil inflow opened toward the inside of the accommodating recess 5d (the center side of the pressure member 5). It may be part 5j.
- the oil inflow portion 5j is composed of an elongated hole opened in the axial direction of the pressure member 5, and the oil inflow portion 5j, the groove portion 5f, and the oil outflow portion 5g (similar to the previous embodiment).
- the oil flow passage is formed by (the thing). As a result, as shown in FIG.
- the oil supplied from the insertion hole 3a reaches the inside of the accommodating recess 5d from the oil inflow portion 5j which is largely opened in the axial direction by the centrifugal force (see the arrow Ra in the figure). It flows through the groove portion 5f and flows out from the oil outflow portion 5g (see the arrow Rb in the figure).
- the oil flow passage is sufficient as long as it is formed in the pressure member 5 and can flow oil toward the driven side clutch plate 7b attached to the pressure member 5, and is a passage that does not pass through the accommodating recess 5d. You may.
- the power transmission device of the present invention can be applied to various multi-plate clutch type power transmission devices such as automobiles, three-wheel or four-wheel buggies, and general-purpose machines, in addition to motorcycles.
- the driven side clutch plate is attached to the clutch member and the pressure member, and the pressure member is a power transmission device having an oil flow passage formed so that oil can flow toward the driven side clutch plate attached to the pressure member. If so, it can be applied to those having different appearance shapes or those to which other functions are added.
