<p>PROBLEM TO BE SOLVED: To provide a pressure mechanism which presses a pressure member against a member to be pressed by rotating a cam, configured to reduce impact noise to be generated when pressure is applied and maximum torque during cam rotation, with a simple configuration.SOLUTION: A pressure mechanism 50 for pressing a pressure member 30 against a member 40 to be pressed includes: pressing force generation members 51, 51d; first members 52, 52d for pressing the pressure member against the member to be pressure by the pressing force generated in the pressing force generation members; second members 55, 55d for variably applying the pressing force to the first members; and rotatable cams 58, 58d which are arranged between the first and second members. The cams include a plurality of peripheries P1, P4 which cancel rotating force of the cams with the pressing force, when coming into contact with the first and second members.</p> |
