PURPOSE: To provide free motion in the thrust direction and a free distance against a rubber elastic damping force body without a rotational backlash within an oscillating flat surface and to avoid impact in the case of a change- over process of inside outside change-over systems by combining a rectangular parallelopiped slide block with a square bore of a universal coupler holder. CONSTITUTION: Rotation of a rectangular parallelopiped slide block 4 around a shaft center 21 on an oscillating surface 20 as its center is held with no backlash by a spring steel sheet 7 having engagement tongue piececes 8, 9 in a square bore 3 of a universal coupling holder 2. Additionally, a rubber elastic damping body 10 consisting of a base plate 30 and two ribs 31 is vulcanized and connected to both side surfaces of the slide block 4, and a free motional distance is provided in the thrust direction 25 of the slide block 4 regarding the square bore 3. Consequently, it is possible to separate without feeling impact peak force of a change-over process on a change-over lever of an inside change- over system. |
