Abstract
A clutch device includes a first clutch, a second clutch, a diaphragm spring and an intermediate spring. The diaphragm spring transmits a pressing force to the first clutch and the second clutch. The intermediate spring applies a coupling maintaining force to the first clutch and the second clutch so that minimally power transmitted states of the first clutch and the second clutch are maintained while a pressing force is not being applied to the first clutch and the second clutch.
