Further, a control device (16) receives an operation signal that is output when the switch (15) is moved to the lock position or the unlock position and controls switching of a magnetic switching valve (13) so that the pressure in a hydraulic pump begins to increase and so that, after a set time has passed, the pressure in the hydraulic pump stops increasing.
