PROBLEM TO BE SOLVED: To provide an automatically interrupting device for a friction clutch simplifying a structure to be capable of manufacture of a total unit into compactness at a low cost. SOLUTION: A mechanical automatic operation force-generating device capable of automatically operating a clutch release mechanism interrupting a friction clutch is constituted by a motor 3, an intermediate shaft gear 6 having a large diametric gear 6a meshed in parallel with a motor gear 5 to decelerate rotation and a small diametric gear 6c, a swivel lever 8 having a large diametric gear 8a meshed with the small diametric gear 6c of the intermediate shaft gear 6 to decelerate rotation and an arm 8c, and a push rod 10 connected through a connection pin 9 in a tip end of the arm 8c of the swivel lever 8.
