Claims

[Scope of utility model registration request]

A transmission means is provided between the fixed body and the drive shaft body, and the transmission means generates a braking force or transmission power by alternately overlapping friction plates and friction mating plates and pressing them together, and this transmission means includes the friction plates. In a power transmission device, a piston is arranged to press a friction mating plate against a fixed body, the piston is pressed against the transmission means by a compression spring, and is configured to be retracted from the transmission means by fluid pressure. A friction plate is held movably only in the axial direction by one of the inner circumferential surface of the drive shaft and an outer circumferential surface of the drive shaft body, and a friction partner plate is held by the other,
A spring means is interposed between either the friction plates or the friction mating plates, and the spring means is arranged around the side where the friction plates or the friction mating plates are held, and the spring means is arranged between the friction plates and the friction mating plates. The spring means is locally provided at two or more locations in the circumferential direction in areas where the plates do not come into contact with each other, and the spring means has an elastic repulsion force capable of separating the friction plates or the friction mating plates from each other. What is claimed is: 1. A power transmission device characterized in that the power transmission device has a strength capable of separating a friction plate and a friction partner plate.
