Patent ID: 8869643

Claim:
An operation input device comprising: an operation body having a handle portion, the handle portion being configured to be held by a user and having a virtual operation axis line, the operation body being configured to tilt together with the handle portion in a case where a tilting operation is performed in such a manner that the user holds the handle portion and tilts the operation axis line of the handle portion, and the operation body being configured to move together with the handle portion parallel to a direction of the operation axis line in a case where a depressing operation is performed in such a manner that the user holds the handle portion and depresses the handle portion along the direction of the operation axis line; a tip end portion disposed at an end of the operation body in the direction of the operation axis line, the tip end portion being pushed in a depressing direction; an abutment portion having an abutment surface, the tip end portion moving with abutting on the abutment surface during the tilting operation, and the tip end portion abutting on the abutment surface and standing still during the depressing operation; and an engaging portion disposed in the abutment portion, wherein the engaging portion engages with a part of the operation body during the depressing operation so that the engaging portion restricts a tilting motion of the operation body in the depressing operation; wherein the operation body includes a tube portion for accommodating the tip end portion under a condition that the tip end portion is pushed in the depressing direction, the tip end portion being disposed within and movable with respect to the tube portion and the tip end portion being biased with respect to the tube portion, wherein the tube portion extends in the direction of the operation axis line, wherein a part of the operation body is a part of the tube portion; and wherein the engaging portion is a concave portion disposed on the abutment portion so that a tip end of the tube portion is inserted in the engaging portion during the depressing operation.
