PURPOSE:To make a titled device simple and small-sized, and to simplify incorporation to the device and its maintenance, by providing a position indicating part, a selecting part and a current direction switching part on one shaft, and containing them as one unit in a housing. CONSTITUTION:A position indicating part A, a selecting part B and a current direction switching part C are coaxially provided on a shaft 4 in a housing 2 and are formed as one unit. When a position of a reciprocating moving body is indicated by turning a knob 1 of the indicating part A, the selecting part B is interlocked with the knob 1 and selects a dividing line corresponding to the position indication from in the dividing lines of a rotation dividing part F, drives a DC motor 29 by a portion of its line, and moves the moving body G to the indicated position. When returning it to its original position, the motor 29 is rotated in reverse, and the moving body G is returned. Therefore, the operation part is formed as a unit, and its installation to the device and its maintenance can be executed easily. |
