出器の点検装置。[Scope of Claim for Utility Model Registration] Inspection of a boom operating state detector for detecting the operating state of the boom in a boom work vehicle that is equipped with a boom that can be raised, extended, and rotated and that can be stored in a predetermined storage position. The apparatus includes an actuation amount/direction calculation means for calculating an actuation amount and an actuation direction of the boom from a retracted state stored in the predetermined storage position based on a detection signal from the boom actuation state detector; boom return actuating means for operating the boom in a direction opposite to the calculated actuation direction by the actuation amount calculated by the actuation amount/direction calculation means, and the boom operated by the boom return actuation means 1. A boom operating state detector inspection device, wherein the boom operating state detector is stored in a retracted position so that normal operation of the boom operating state detector can be inspected.
