Abstract
A lock mechanism includes a casing that is fixed to a side surface of a body, a handle disposed rotatably on the outside of the casing, and a transmission section, which is capable of transmitting a drive force applied by the handle. An end of a guide rod making up the transmission section is connected in a body surrounding groove of a piston rod disposed inside the body. In addition, by rotating the handle, the guide rod of the transmission section is displaced vertically (upward and downward), such that an arm is rotationally displaced through a toggle link mechanism by displacement of the piston rod along the axial direction.
