A clutch part is disposed between the pressure receiving part and the pressure applying part. A cam mechanism includes a first cam part and a second cam part. The first cam part and the second cam part are offset from the clutch center and the pressure plate in an axial direction. The first cam part includes a first slope. The second cam part includes a second slope opposed to the first slope. When the first cam part is rotated relatively to the second cam part in a first direction making up a circumferential direction, the first and second slopes are pressed against each other and separate from each other. The pressure applying part moves toward the pressure receiving part as the first cam part and the second cam part separate.

Abstract: A clutch device includes a first rotary member, a second rotary member, a clutch part, a support member, and a cam mechanism. The cam mechanism separates the support member and the second rotary member away from each other in the axial direction when the support member and the second rotary member are rotated relatively to each other. The cam mechanism includes a first cam surface, a second cam surface, a third cam surface and a fourth cam surface. The first and second cam surfaces are included in the support member. The third and fourth cam surfaces are included in the second rotary member. The first and second cam surfaces tilt to face axially inside and face oppositely to each other in a circumferential direction. The third cam surface is opposed to the first cam surface. The fourth cam surface is opposed to the second cam surface.

Abstract: A clutch center includes a pressure receiving part and is accommodated inside the clutch housing. A pressure plate includes a pressure applying part disposed at an interval from the pressure receiving part in an axial direction. A clutch portion is disposed between the pressure receiving part and the pressure applying part, and allows and blocks transmission of a power between the clutch housing and the pressure plate. A first cam portion is disposed on one side of the pressure plate in the axial direction, and increases an engaging force of the clutch portion when a forward drive force acts on a clutch device. A second cam portion is disposed on the other side of the pressure plate in the axial direction, and reduces the engaging force of the clutch portion when a reverse drive force acts on the clutch device.

Abstract: An automatic volume control to prevent the listener from having an odd sensation is obtained with a plurality of conditions taken into considerations. A plurality of control rules required to infer using fuzzy logic a volume correcting value on the basis of frequency band component levels, L, M and H and a volume level V are stored beforehand in a volume correcting value inferring portion 13. The volume correcting value inferring portion 13 obtains inference results of the individual control rules on the basis of the individual frequency band component levels L, M, H input from a filter circuit 12 and the volume level input from an audio reproducing portion 14, obtains a weighted mean of the respective inference results as a volume correcting value Z, and inputs the volume correcting value to the audio reproducing portion 14 to automatically correct the volume.
