Patent ID: 6901678

Claim:
A measuring head, comprising: a sensing pin disposed at the measuring head's tip, a seesaw member which is supported to be swingable pivoting on a fulcrum member, an urging member which urges the seesaw member in one direction, a detector which is disposed on the other side than said sensing pin with respect to said fulcrum member and detects any displacement of said sensing pin by detecting the displacement of said seesaw member, and a retracting device which moves said sensing pin from its measuring position to a predetermined retracting position, wherein said retracting device comprises: an electric motor, a feed screw which is driven rotationally by the electric motor, a nut which screws onto the feed screw, is obstructed by a stop from turning, and is linearly moved along the feed screw by the turning of said feed screw, and an inclined member which is formed on the nut or coupled to the nut and has an inclined face which is in contact with said seesaw member on the other side than said sensing pin with respect to said fulcrum member, wherein said sensing pin being moved from its measuring position to the predetermined retracting position by linearly moving said inclined face to swing said seesaw member.
