PROBLEM TO BE SOLVED: To prevent increase of rotation resistance of a driven member to prohibit normal rotation of the driven member due to repeated rotation action of the driven member to which power from a drive source is transmitted through friction force of a friction member is transmitted. SOLUTION: This friction clutch device 60 is provided with a rotary shaft 53a, a pinion gear 53, a trigger lever 51 to which the rotation shaft 53a is inserted, and which is rotatable relative to the rotary shaft 53a, a bearing part disposed to hold the trigger lever 51 and the pinion gear 53 to shaft-support the rotary shaft 53a, a friction member 58 provided between the pinion gear 53 and the trigger lever 51, and a flat washer 59 provided between the bearing part 56d and the trigger lever 51. The flat washer 59 is composed to rotate integrally with the rotary shaft 53a. Even when friction force between the flat washer 59 and the bearing part 56d is increased, the friction force does not prohibit rotation action of the trigger lever 51. COPYRIGHT: (C)2007,JPO&INPIT
