<p>PURPOSE: To set the operating physical force of a joy stick lever at a prescribed value since it is necessary from the standpoint of human engineering for the operating physical force of a wrist to the outside to be smaller in comparison with the operating physical force to the inside. CONSTITUTION: This device is provided with a roller supporting arm 11 fixed to the boss of a joy stick lever 2, roller 12 pivotally supported by this roller supporting arm 11 so as to be freely rotated, and respective cam planes 15b and 16b to be abutted to this roller 12. At the same time, this device is composed of respective operating cams 15 and 16 pivotally supported by a main body 1 of a manipulator on both the sides of the fluctuating direction of the roller supporting arm 11 so as to be freely fluctuated, spring 21 spread in contact with these respective operating cams 15 and 16 for energizing the roller 12 to abut it to the respective cam planes 15b and 16b, and stopper members 15c, 16c, 22 and 23 for regulating the respective motions of the respective operating cams 15 and 16 to the inside.</p> |
