A reel of a slot machine is rotatably fitted on a shaft of a motor and coupled to the shaft by an elastic member. When the motor is started, energy is stored in the elastic member, and the reel is suddenly caused to start rotation at a high speed by the energy stored in the elastic member. A projection on the reel engages a drive lever to fix the relative position of the parts after the initial period of relative movement of the shaft and reel. The elastic member can be a coil tension spring or a leaf spring sandwiching the drive lever, a portion of the leaf spring on the rear side of the lever being secured to the reel.
