| 摘要 | PURPOSE:To set up the positional relation between a mechanism lever and a cabinet to an optional using position by forming a conical coil spring between the inside of the cabinet and the root part of each pushbutton. CONSTITUTION:The pushbutton device is constituted of pushbuttons 1a, 1b, the cabinet 2, the mechanism lever 3, and coil springs 6, and when one pushbutton 1a is depressed, the other pushbutton 1b is moved in the shown arrow direction through the mechanism lever 3. Said coil springs 6 are formed by the conical coil springs 6 like winding structure so that a steel wire material is not contacted at the time of compression. Consequently, the conical coil springs 6 can be compressed up to the diameter of the steel wire material and the limitation of the setting position of the mechanism lever 3 can be suppressed up to said diameter at its minimum. Thus, the positional relation between the position of said lever 3 and the inside of the cabinet 2 can be set up optionally. | ||||||
