An object of the present invention is to provide a multiple disc clutch apparatus which can reduce both the drag torque and the sticking torque and simultaneously reduce the weight of the multiple disc clutch apparatus. According to the present invention, there is provided a multiple disc clutch apparatus comprising substantially annular multiple clutch discs to be connected to an input-side from an engine; substantially annular multiple clutch plates to be alternately laminated with the clutch discs and connected to an output-side to a wheel; and frictional members secured on surfaces of the clutch discs opposing to the clutch plates and adapted to be capable of press-contacting with or separating from the clutch plates; a power from the engine being transmitted to the wheel when the clutch discs and the clutch plates are press-contacted each other via the frictional members and the power transmission between the engine and the wheel being blocked by releasing the press-contacting force characterized in that depressions are formed on each clutch plate extending along its periphery and toward radially inward; and that a part of the frictional members is positioned within a region of the depressions. |
