The present invention relates to a wet type hydraulic multiple clutch. The wet type hydraulic multiple clutch according to the present invention includes a clutch housing, and a hub gear freely rotating with respect to the clutch housing. Multiple clutch plates and clutch disks are spline-coupled to the inner circumferential surface of the clutch housing and the outer circumferential surface of the hub gear to be positioned alternately. A piston is installed in the clutch housing, and a return spring is installed in the front of the piston. A passage is formed in a linear shaft, the piston, the hub gear, and the clutch housing to allow oil to flow to the outside of the clutch housing from the linear shaft. In an opening of the clutch housing, a pressure plate is assembled to be retained using a snap ring. An oil chamber is installed on the outer circumferential surface of the hub gear facing the inner end of the pressure plate. One or more contact protrusions coming in contact with the inner end of the pressure plate are formed on the outer circumferential surface of the oil chamber. |
