(EN) PROBLEM TO BE SOLVED: To provide a technique to reduce, in an operation device having an operation part rotating around a predetermined axis, a backlash on the operation part in a thrust direction, while suppressing the occurrence of friction accompanying the rotation of the operation part.
SOLUTION: The operation device includes: an operation part which rotates around a predetermined axis; shanks (33, 34) which are disposed along the axis, and include a first end part (34B) and a second end part (33B) protruding to mutually opposite directions along the axis, and are operated integrally with the operation part; guides (43, 47, 53, 57) to which a part of the shanks is inserted so as to restrict the shanks from moving to the radial direction; a first prescription part (42) which contacts to the first end part of the inserted shank to prescribe a position to a thrust direction; a second prescription part (52) which is pressure-welded to the second end part to make the first end part contact to the first prescription part; and an engaging part (55) which is provided in an integrated manner with the second prescription part, and contacts to the second end part to suppress the shanks from releasing from the guides.

【課題】所定の軸線を中心に回動する操作部を備えた操作装置において、操作部の回動に伴う摩擦の発生を抑制しつつ、前記操作部のスラスト方向のガタを軽減する技術の提供。
【解決手段】所定の軸線を中心に回動する操作部と、前記軸線に沿って設けられ、当該軸線に沿って相反する方向に突出した第１端部（３４Ｂ）と第２端部（３３Ｂ）とを有し、前記操作部と一体に動作する軸部（３３，３４）と、前記軸部の一部を挿入され、前記軸部のラジアル方向への移動を規制するガイド（４３，４７，５３，５７）と、前記挿入された軸部の前記第１端部に当接してスラスト方向の位置を規定する第１規定部（４２）と、前記第２端部に圧接され、前記第１端部を前記第１規定部に当接させる第２規定部（５２）と、前記第２規定部に一体に設けられ、前記第２端部に当接して前記軸部の前記ガイドからの離脱を抑制する係止部（５５）と、を備える。
