PURPOSE:To eliminate the need to work an operation rod and to facilitate the attachment of a handle to the operation rod by inserting a coil spring in the hole of the handle wherein the operation rod is inserted. CONSTITUTION:The handle body 1 is provided with the hole 2 wherein the operation rod A is inserted. The coil spring 3 having an internal diameter smaller than the external diameter of the operation rod is inserted into this hole 2. Then when the operation rod is pressed in the spring 3, the operation rod is clamped by the spring 3 and fixed. When the handle body is to be rotated counterclockwise, the tip part 32 of the spring 3 engages with a groove 32 formed in the hole 2, so the handle 1 does not rotate. When the handle 1 is to be rotated clockwise, on the other hand, the tip part 33 of the spring 3 engages with a groove 24 formed in the hole 2, so the handle body 1 does not rotate. Thus, the need to work the operation rod is eliminated and the attachment of the handle to the operation rod is facilitated. |
