。[Claims for Utility Model Registration] A support plate that is provided so as to be movable toward and away from a workpiece into which a hole to be inspected has been machined, and a guide member that is attached to the support plate so as to be slidable in the axial direction of the hole. a measuring pin that is supported and has a diameter that allows its tip to be inserted into the hole, and is interposed between the measuring pin and the guide member;
a spring member that biases the measuring pin toward the hole; a groove formed on a side surface of the measuring pin; and a groove provided movably in parallel with the support plate, the spring member being provided to be movable in parallel with the supporting plate, so that the measuring pin is in a normal position. A hole depth inspection device comprising: a detection plate that engages with the groove at a certain time; and detection means that determines whether the depth of the hole is good or bad based on the amount of movement of the detection plate. .
