棒状部材の周長測定装置。 One end side of a flexible member having a loop formed in its intermediate portion for insertion of a rod-shaped member is fixed, and a reciprocating member is biased and moved in the loop diameter reduction direction by a spring-biased measuring shaft. A circumference measurement and display device connects the other end of the flexible member and measures and displays the circumference of the rod-shaped member inserted into the loop based on the amount of movement of the reciprocating member against the spring. On the other hand, the cylinder rod of the damper cylinder, which moves slowly in one direction,
connecting a second spring that biases and moves the cylinder rod in a slow movement direction and locking and interlocking the cylinder rod with the reciprocating member;
The cylinder rod is configured to apply a braking force to the movement of the reciprocating member in the loop diameter contracting direction, and further includes a rod return mechanism that returns and fixes the cylinder rod to its initial position against the biasing force of both springs. A circumferential length measuring device for a rod-shaped member, characterized in that it is provided with an operating tool for switching the rod return mechanism to an unfixed state.
