Claims

[Scope of utility model registration request]

At the shaft ends of the drive shaft and driven shaft, which are arranged on the same axis,
Each has a non-circular cross section in which a small radius circumferential surface and a large radius circumferential surface repeat, and the non-circular cross section forms a small diameter portion extending in the same shape in the axial direction, and the small diameter portion at both ends of the shaft A plurality of rollers extending in the axial direction across the small diameter portion are brought into contact with each other, and the outer periphery of the roller is pressed by a pressing piece extending from a cylindrical portion held on one shaft side toward the other shaft side. ,
An overload prevention device for a power transmission shaft characterized by being biased toward the shaft surface side.
