Claims

[Scope of utility model registration request]

One of the active clutch plate coupled to the drive source side and the driven clutch plate coupled to the load side is formed in a resin drum-shaped case having an engagement groove on the inner circumferential surface, and the other is housed in the drum-shaped case. an engaging member formed of a resin disc that is rotatably fitted and has a clutch mechanism housing recess on the plate surface on the fitting side, and that engages the clutch mechanism housing recess with the retaining groove; In a clutch for an electric telescoping antenna that includes a sliding member that slides on the inner peripheral surface of a drum-shaped case and an elastic member that is compressively mounted between these two members, the sliding surface of the sliding member is made of polyurethane. A clutch for an electric telescopic antenna characterized by being formed of a rubber-like elastic body.
