Claims

[Scope of utility model registration request]

a measuring device main body provided with a movable stage movable in the axial direction of the stepped portion of the object to be measured and in a direction perpendicular to the axis; a slider provided within the main body and slidable along the axial direction; a support member loosely inserted into the slider;
One end side is supported by a support member, and the other end side is an elongated rond that forms a measuring element that contacts the object to be measured and extends, and a rear part of the support member for vertically swinging the rond. a pin that is fitted and fixed to the slider;
a first urging means that always urges the rond forward and downward, and is parallel to the axis using a pin as a fulcrum during measurement, and is inserted in the slider and the support member in a direction perpendicular to the axial direction of the rond; a second biasing means provided in the main body for biasing the probe toward the object to be measured via the slider; and a touch switch disposed on the rear end side of the support member. A step position measuring device comprising:
