The screw engagement portion (10) between the pulley (9) (the boss (9g)) and the shaft (1a) is provided with a thread in a direction to increase the tightening torque when the pulley (9) is driven. A breakable part (1i) which is broken by the axial tension produced in accordance with the tightening, when the tightening torque acting on the screw engagement portion (10) is above a predetermined value, is also provided. With this structure, the stress to break the breakable part (1i) is not a shearing stress but is mainly a tensile stress. Unlike the shearing stress, the tensile stress is substantially uniformly distributed in a cross section and, hence, the stress distribution of the breakable part (1i) can be relatively precisely predicted and analyzed. Consequently, the necessity of determining the dimension and the material, etc. of the breakable part (1i) by trial and error is reduced, thus leading to facilitation of the design and development. The breakable part (1i) can be certainly broken at a predetermined torque, without being subject to fatigue fracture.
