Abstract
A breakage prevention mechanism is configured to prevent deformation or breakage of a crossbar and transfer the work even in the condition where a pair of left and right arm supporting the both end of the cross bar is displaced beyond assumption. The breakage prevention mechanism is equipped with a pair of arms which is synchronized and moves approximately parallel, and a crossbar bridged between the top end of the arms. Both end of the crossbar and the arm are connected pivotably around two axis. Both end of the crossbar are configured to be slidable against the arm in X axis direction. The plunger is placed between both end of the crossbar and arm, in which protects the crossbar by restraining the pivoting and the sliding of both in the normal condition and releasing the restraint when the unintended force is given.
