| 摘要 | A linear extension and retraction mechanism has a plurality of first connection pieces connected bendably and a plurality of second connection pieces connected bendably. The first and second connection pieces become linearly rigid when joined together and return to a bent state when separated. The first connection piece has a main body part. A pair of bearing sections is provided on front both sides of the main body part, and a single bearing section is provided on a rear center of the main body part. In order to limit bending of the connected first connection pieces to a front surface side from a linearly aligned posture, a projection section protruding to the rear is provided on the bearing section on the rear of the main body part, and a receiving section adapted to receive the projection section is provided between the pair of bearing sections on the front of the main body part. | ||||||
