Drehmomentübertragungsvorrichtung

摘要

A torque limiter to be operatively coupled to an engine is secured to the outer periphery of a driving shaft through screwing-engagement. The driving shaft and the torque limiter are screw-engaged and fixed to each other so that the torque limiter is pushed or urged against a seating face formed at the outer periphery of the driving shaft. The seating face abuts against the torque limiter restricting the screwing-movement of the driving shaft. Rotation force is transmitted between the driving shaft and the torque limiter via the seating face. A cylindrical member is disposed between the torque limiter and the seating face of the driving shaft. The cylindrical member is press-fitted and fixed to the outer periphery of the driving shaft, so that the power transmission between the driving shaft and the torque limiter is also performed through the press-fit portion between the cylindrical member and the driving shaft.
