PROBLEM TO BE SOLVED: To reduce the possibility that foreign matter in a mission case is drawn to a slide interface between a piston member and a cylinder chamber.SOLUTION: A transmission includes a piston member 101 inserted into a lateral cylinder chamber 100 and supported in a slidable manner. Of an insertion place of the piston member 101 to the cylinder 100, at a place that is at a position drawn into the cylinder chamber 100 in a most retreat-in position and is equivalent to a position exposed to the outside of the cylinder chamber 100 in the most retreat-in position, a recess part 101c opened upwardly is formed so as to form a space between itself and a downward surface of the cylinder chamber 100.SELECTED DRAWING: Figure 10 【課題】ミッションケース内の異物がピストン部材とシリンダ室との摺接面間に引き込まれる可能性を低減しようとするものである。【解決手段】横向きのシリンダ室１００に挿嵌されて摺動自在に支持されたピストン部材１０１を備え、ピストン部材１０１のシリンダ室１００への挿嵌箇所のうち、最退入位置ではシリンダ室１００内へ引き込まれた位置にあり、かつ最突出位置ではシリンダ室１００外へ露出する位置に相当する箇所に、シリンダ室１００の下向き面との間に空間を形成するように上向きに開放された凹部１０１ｃが形成されている【選択図】図１０
