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