Title: Setting apparatus
Inventor: IEERUTO YORUIENSEN
IPC: G05G5/16
Filed: 1989-07-12
Abstract: PURPOSE: To provide a neutral position which can be adjusted by allowing abutting and/or pressure faces to be adjusted in a relation with a perfect body where they are provided. CONSTITUTION: When the rotational knob 18 of a grip for operation 2 is rotated, an abutting main body 7 inclines and the neutral position of the grip for operation is dislocated from a vertical line and it inclines. When the grip for operation 2 is in the neutral position which is vertical, the rotary angle of the rotary knob 18 is zero degree and the axis of pressure face main body 20 is always matched with the axis of the grip for operation 2. Thus, the grip for operation 2 is in the neutral position between both positions. The pressure face main body 20 is turned so that a prescribed angle between the pressure face main body 20 and a pressure face 8 comes into the vertical plane with respect to an operation plane.  When the abutting main body 7 completely inclines to the right end, the abutting face 16 takes the same angle within the plane and the angle between the abutting face 16 and a vertical axis in the operation plane becomes 90 degrees. Thus, signal change devices 4 and 5 have different setting in all the neutral positions on the grip for operation 2.
