PURPOSE:To prevent uneven rotation or vibration by coupling first and second members in cross then coupling the first and second members slidably to cams secured respectively to drive member and driven member. CONSTITUTION:First and second members 13a, 13b are coupled in cross then coupled slidably in perpendicular direction against the shaft to drive member 12 and a cam 11 fixed to drive member respectively. Consequently, parallel motion of drive member 12 and cam 11 against the shaft is absorbed through sliding of first and second members 13a, 13b against the cam 11 and the drive member 12 while since the inclination of drive member 12 and the shaft of cam 11 is absorbed through rotation of first and second members 13a, 13b, speed reduced rotary force can be transmitted from the drive member 12 to the driven member without uneven rotation and vibration. |
