<p><P>PROBLEM TO BE SOLVED: To provide a cramp device capable of surely locking a swing bar with a small force. <P>SOLUTION: The cramp device includes: a body 11; a swing bar 12 supported by the body 11 through a swing bar shaft freely to move, drawing a circular arc; a cam 13 supported by the body 11 through a cam shaft 132 freely to move, drawing a circular arc; and a connecting arm 14 connected to the swing bar 12 through a first connecting arm shaft 141 freely to move, drawing a circular arc, and connected to the cam 13 through a second connecting arm shaft 142 freely to move, drawing a circular arc, so as to connect the swing bar 12 and the cam 13 to each other. When the cam 13 moves, drawing a circular arc, toward an end of a movable range of the circular movement, the movement of the cam 13 is transmitted to the swing bar 12 through the connecting arm 14, and the swing bar 12 moves, drawing a circular arc, and the cam 13 abuts on the swing bar 12 in the one end of the movable range of the circular movement. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
