伸縮形アンテナ装置用クラッチ機構。A driving clutch plate rotated by a motor, a driven clutch plate that receives rotational force from the driving clutch plate on one side opposite to one side of the driving clutch plate and applies a driving force to an antenna element, and the driven clutch plate. an engaging portion provided between opposing surfaces with the active clutch plate so as to exert a predetermined locking force against relative rotation of both clutch plates; A first engaging portion is arranged on a plurality of concentric circles having different diameters around the rotating shaft on the surface of the driving clutch plate facing the driven clutch plate, and the first engaging portion is connected to the driving clutch plate. a second engaging portion provided on the opposing surface of the driven clutch plate so as to engage at a predetermined relative rotation angle between the clutch plate and the driven clutch plate; Engages with the first engaging part and/or the second engaging part with a degree of engagement smaller than the degree of engagement between the first and second engaging parts at a rotation angle at which the engaging part does not engage with the engaging part. A clutch mechanism for an electric telescoping antenna device, characterized in that the clutch mechanism comprises a third engaging portion provided on an opposing surface of the driving clutch plate and/or the driven clutch plate.
