<p>PURPOSE: To prevent a switch function of a joy stick from being defected or its mechanism from being damaged even when a shock is exerted to an operation knob of the joy stick. CONSTITUTION: This absorber is provided with a slider 3 sliding by the operation in the circumferential direction around a shaft center of an operation knob 1, a contact plate 12 in press contact with a contact 13 by the elastic deformation by the operation of the operation knob 1 in the axial direction, and a stem 11 fixed to the contact plate 12 and elastically deformed by an overload of the operation knob 1 in the axial direction. When an overload such as a shock is exerted to the operation knob 1, the stem 11 is deformed to absorb the shock so as to prevent defect of the switch function and damage to the mechanism of the joy stick.</p> |
