Abstract

PURPOSE:To prevent a control from being unnecessarily rotated by a very simple structure by a method wherein a buffer material is provided to the rear side of the control of a main body case as pressed against it, and a bearing part bearing against the rear side of the control is provided to a part of the main body case on the side opposed to the buffer material as protruding. CONSTITUTION:An equipment case 1 used for a low frequency therapy device is provided with a strength-control rotary control 2, which controls the intensity of a given current, located at the upper part inside it and a speed-control rotary control 3, which control the frequency of vibration, located adjacent to the control 3. The controls 2 and 3 are circular and provided with a rugged circumference 4 respectively. Most of the controls 2 and 3 are provided inside the main body case 1 and a part of the circumferential part of each of the controls 2 and 3 is made to protrude from the side wall of the case 1. A U-shaped piece 8 is formed on the case 1 striding the controls 2 and 3 and hoding a buffer material 10 between its forks. A pair of bearing parts 11 and 11 is formed on a part of the case 1 opposed to the buffer material 10 and bears on steps 7 of the controls 2 and 3.
