<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive frictional engaging device for a vehicle for making both compatible of high heat resistance of a friction material and a high friction coefficient, without causing an enlargement. <P>SOLUTION: The friction material 40 is constituted of a first friction member 42 relatively high in heat resistance and a second friction member 44 having a friction coefficient higher than the first friction member 42. A separator 32 and a frication plate 34 are frictionally engaged in the first place via the first friction member 42 when these are interposingly pressed in the axial C direction. Next, due to being frictionally engaged via the second friction member 44 in addition to the first friction member 42, frictional engagement is performed via the first friction member 42 in an initial stage of the frictional engagement of requiring high heat resistance since a rotating speed between the separator 32 and the friction plate 34 is high, and the frictional engagement is performed via the first friction member 42 and the second friction member 44 in the last stage of the frictional engagement of requiring a high friction coefficient for putting the separator 32 and the friction plate 34 in a complete engaging state. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
