ABSTRACT:
A damper for the door of a cassette housing in a cassette tape recorder is formed by unrotatably inserting a resisting member provided with radially extended vanes around a support shaft protuberating from a base plate and setting the resisting member within a cup-shaped rotary member thereby allowing the vanes to slide frictionally on the inner wall surface of the rotary member. This damper is mounted in the machine proper of the recorder by fastening the resisting member to the machine proper through the medium of the fitting member and pivotally attaching the door to the rotary member by utilization of a rack and pinion. The opening and closing motion of the door is braked by the frictional slide of the resisting member on the inner wall surface of the rotary member. Thus, the shocks and vibration produced by the opening and closing motion of the door are abated.
