Interference between a spring and a shaft is prevented in a torque shock absorber device which uses a coil spring. The torque shock absorber device has a shaft which is fixed on a base plate, and a sleeve is installed which is free to rotate against the shaft. On the sleeve, a torque transmission part is installed. One end of the coil spring is inserted and fixed in a slot of the shaft. The coil spring is wound on a peripheral part of the shaft and sleeve, and the other end is fixed on the torque transmission part. When torque is applied on the torque transmission part, the sleeve is rotated with the wound coil spring and no friction is generated between the sleeve and shaft.
