A power transmitting apparatus which can suppress the rotational vibrations by suppressing rotation of the pressure member relative to the clutch member is provided. The power transmitting apparatus can comprise a clutch housing rotatable together with an input member and a plurality of driving-side clutch discs mounted thereon; a clutch member with a plurality of driven-side clutch discs mounted thereon and interleaved with the driving-side clutch discs; and a pressure member axially movably relative to the clutch member to increase or release the press-contacting force acting on the driving-side clutch discs and the driven-side clutch discs. The power transmitting apparatus can further comprise one or more slide-suppressing members for applying sliding resistance to the pressure member when the pressure member is rotated relative to the clutch member.

Power transmitting apparatus

A clutch device is provided which facilitates an operation of checking whether or not spring seats have been properly disposed and effectively prevents falling off or a change in attitude of the spring seats, thereby reducing the labor required for manufacture. A clutch deviceincludes a pressure platewhich presses friction plateswhich are rotationally driven by a drive shaft against clutch plates. The pressure plateincludes clutch springsand spring seatsdisposed in receiving portionshaving a concave shape. Each spring seathas two plate-shaped armsandextending along the bottomof the receiving portionand has a C-like shape. Protrusionsandproject from the peripheries of the armsand. Recessesinto which the protrusionsandfit are formed in an inner wall portion of each receiving portionat a position near the bottomof the receiving portion
