<p>PROBLEM TO BE SOLVED: To provide frictional engaging equipment that does not rotate a snap ring holding a return spring at a low cost. SOLUTION: Frictional engaging equipment has a large size cylindrical body 16 forming an engaging groove 66 that a frictional plate 67 engages and a small size cylindrical body 37 forming an engaging groove 65 that a frictional plate 69 engages so as to be arranged free rotation relatively in the large size cylindrical body 16. It has a piston 74 that is incorporated in a cylinder 73 fixed to the large size cylindrical body 16 and pushes pressure to the frictional plates 67, 69 as well as a return spring 77 that is fixed between a snap ring 80 engaged by forming a notch partly in the large size cylindrical body 16 and the piston 74 and gives a spring power to the direction where returns the piston 74. It has a fix ring 82 that stops rotation in a large size cylindrical body 16 and is arranged between the snap ring 80 and the return spring 77 and do not transmit a rotation to the snap ring 80.</p> |
