摘要： An extension and contraction device includes a tape driving device configured to perform winding up of the tape and delivery of the tape. The tape driving device has a reel around which the tape is wound, a motive-power source configured to perform the winding up of the tape onto the reel and the delivery of the tape from the reel, a band member in which a first end side is constrained and a second end side is a movable free end, the band member being provided along an outer circumferential surface of the tape wound around the reel in the roll shape, and the band member being configured to press the tape against the reel, and tension adjusting mechanism configured to adjust tension of the band member by regulating a position of the free end of the band member.
