To provide a stop structure of a door closer having excellent switching operability and higher safety regarding an impact or an arbitrary operation by a user etc.SOLUTION: A switching means comprises: a pair of fitting holes formed in a diameter direction of a cylindrical body; a columnar switching shaft attached to the fitting hole; and an abutting part that abuts the switching shaft. One of the pair of fitting holes includes a female screw part, the switching shaft includes a male screw part that is screwed into the female screw part, and a reduced diameter part and an enlarged diameter part are continuously provided in an axial direction. The abutting part includes an abutting end part that can abut against the enlarged diameter part but does not abut against the reduced diameter part, and an abutting base part that can abut against the enlarged diameter part or the reduced diameter part. The switching shaft is moved in the axial direction by one or more rotation of screw-turning operation of the male screw part with respect to the female screw part to change a position of the enlarged diameter part and the reduced part with respect to the abutting part. Thus a stop mechanism is invalidated by switching from a state in which the abutting end part abuts against the enlarged diameter part to a state in which the abutting base part abuts against the enlarged diameter part or the reduced diameter part.SELECTED DRAWING: Figure 1
【課題】切替の操作性に優れ、衝撃やユーザの恣意の操作等に対してより安全性が高いドアクローザのストップ構造の提供。【解決手段】切替手段が、筒状体の直径方向に形成された一対の取付穴と、取付穴に取付けられる柱状の切替軸部と、切替軸部に当接する当接部を備え、一対の取付穴の一方には雌螺子部を備え、切替軸部は雌螺子部に螺合する雄螺子部を備え、軸方向に縮径部と拡径部とを連続して備え、前記当接部は、前記拡径部と当接可能であり且つ縮径部と当接しない当接端部と、前記拡径部若しくは縮径部と当接可能な当接基部とを備えたものとし、雌螺子部に対して雄螺子部の１回転以上の螺合回動操作により前記切替軸部を軸方向へ移動させて、当接部に対する拡径部と縮小部の位置を変更し、当接端部が拡径部と当接する状態から当接基部と拡径部若しくは縮径部とが当接する状態に切り替えてストップ機構を無効化する。【選択図】図１
