Abstract

PURPOSE: To make a detection operable for an abnormal condition of the weak point pin like breakage, bending, etc., by providing a position limiting switch in one engagement portion of the interlocking substance and providing a switch operating material in another engagement portion at a position corresponding to the movement area of said switch.
CONSTITUTION: With an extraordinary strength of force applied to the guide vane (not shown in the drawing) and a weak point pin 5 broken, a sliding flange 5-B, provided on top part of said guide vane side, moves sliding along a slide hole 3-B under against the braking action of a spring 7. Accordingly, a position limiting switch 13, attachably provided in an upper link 3-A, makes a displacement relatively to the sliding flange 5-B, with a switch actuating piece 13A pushed out of a switch guide groove 6-A against a switch spring tension, and the actuating piece 13A is moved turning to a closing posistion of the electric circuit. And even with the weak point pin 5 not coming to be broken, if curved to beyond a prescribed limit, is similarly closed the electric circuit to operate an alarm device or stop command device.
