<p>PURPOSE:To make it possible to eiliminate generation of an impulse sound, by using only one damper unit to damp the return movement of plural operators. CONSTITUTION:Link lever 9 is freely fitted to link pin 5c standing on the right end of operation rod 5 and link pin 7c standing on the right end of operation rod 7. Operation rod 7 and link lever 9 are so constituted that they can slide due to long hole 9a. Operation rods 6 and 8 are linked with each other by link lever 10 through link pins 6c and 8c and long hole 10a so that they can be rotated and slide. Link levers 9 and 11 are linked with each other through link pin 9b so that they can slide, and link levers 10 and 11 are linked with each other through long hole 11a so that they can slide. Contact pin 12 standing on link lever 11 is brought into contact with the operator of an oil damper.</p> |
