Abstract: A clutch device includes a pressure plate movable toward or away from a clutch center and rotatable relative to the clutch center to press input-side rotating plates and output-side rotating plates. The clutch center includes center-side cam portions each including a center-side assist cam surface. At least one of the center-side cam portions includes at least one of a first center-side recess recessed in a first direction from a surface of center-side cam portion at a side of a second direction or a second center-side recess recessed in the second direction from a surface of the center-side cam portion at a side of the first direction.

Abstract: A molding apparatus for obtaining an annular molded article has a fixed die D1 and a movable die D2 capable of forming an annular cavity C. A first block B1 and a second block B2 are formed inside the cavity C in the fixed and movable dies D1 and D2. The blocks form a flow channel R communicating with the cavity C. Thus, gas generated in the cavity C and a molten metal can flow in the flow channel R. A discharge hole B2b is formed in the second block B2 to discharge the gas flowing in the flow channel R to the outside. A forming surface of the flow channel R, in the first and second blocks B1 and B2, is formed in an outer circumferential shape following an inner circumferential shape of the cavity C.
