Working apparatus for construction machine

摘要

A recessed portion 22a is formed at an end surface 22b of a pin 22 provided at a boom 3 to house a case 21a of an angle sensor 21 in the recessed portion 22a, a flange 218 projecting out from the case 21a along the direction of the axis of an input shaft 21b is projected so as to enclose the input shaft 21b outside the movement range of a lever 23. By projecting the flange 218 further out than the distance over which the input axis 21b projects out, the protection provided by the flange 218 for the input shaft 21b is enhanced more effectively.
