PROBLEM TO BE SOLVED: To provide an automatic clutch mechanism capable of easily transmitting a feeling in shifting a gear to a driver through a pedal. SOLUTION: The automatic clutch mechanism 10 shifting the gear while disengaging a clutch 12 interlockingly with one peal operation is provided with a transmission 13, and the clutch 12. The transmission 13 shifts the gear interlockingly with pedal operation. The clutch 12 is constituted by an elastic material 21, and an engagement part 22 for engaging the transmission 13 and an engine 25 by receiving elastic reaction force of the elastic material 21. The elastic material 21 in the clutch 12 is provided with a tilt reduction region where tilt of a variation amount of an elastic load with respect to deformation of the elastic material 21 is smaller as larger as the deformation is. The tilt reduction region is included in a use region of the elastic material prescribed by operation of the clutch 12. COPYRIGHT: (C)2008,JPO&INPIT
