<p><P>PROBLEM TO BE SOLVED: To provide a wet type multiplate frictional engagement device capable of inhibiting the generation of judder by inhibiting the transmission of vibration by a structure itself of the wet type multiplate frictional engagement device. <P>SOLUTION: This wet type multiplate frictional engagement device 10 comprises frictional plates 31 and mating plates 33 alternately arranged in a drum 41, a spline 43 mounted on an inner periphery of the drum 41 in the axial direction of the drum 41, projections formed on outer peripheries of the mating plates 33 and engaged with the spline 43, and a piston 40 for bringing the frictional plates 31 and the mating plates 33 into close contact with each other. A groove-shaped accommodating part 24 is formed on a pressing face of the piston 30, and an elastic ring 26 is mounted in the accommodating part 24. The elastic ring 26 is made out of a composite material of an elastomer material or a resin and fiber, and adhered and fixed to the accommodating part 24. The vibration reducing effect can be achieved by the elastic ring 26 in a case when the load is comparatively small, and the device can be used for a long period. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
