Abstract

A drive device ( 7 ) that unwinds, in a first direction, a wire (WR) connected to an operation target ( 41, 551, 552 ) with predetermined tension and pulls the wire in a direction opposite to the first direction to cause the operation target to perform an action includes a motor ( 71 ), a first rotating member ( 74 ) that can be rotated by the motor in a second direction and in a direction opposite to the second direction about a rotation axis (Rx 5 ), a pulling member (TM) that is provided rotatably coaxially with the first rotating member, holds an end (WR 1 ) of the wire, rotates in the second direction to unwind the wire in the first direction, and rotates in the direction opposite to the second direction to pull the wire in the direction opposite to the first direction, and a pulling member side urging member ( 77 ) that urges the pulling member in the direction opposite to the second direction relative to the first rotating member, in which, when the wire is moved in the first direction due to an external factor, the pulling member rotates in the second direction against an urging force of the pulling member side urging member, to unwind the wire in the first direction.
