Abstract
A spherical portion of a shaft is provided with engagement projection portions at two locations to be arranged by intervals of 90° in the rotational circumferential direction and there is provided a guide portion including limiting faces for being engaged to the engagement projection portions to lock a swing motion of the shaft and release recessed portions for releasing the engagement of the engagement projection portions at a switch operational position where the operational knob is rotated to allow an operation of the inclination motion by the operational knob in a plane direction due to the swing of the shaft. This construction thus prevents the operation of the inclination motion by the operational knob when the operational knob is at a neutral position.
