Abstract
An initial tension device has a wire cable for connecting a drive unit and a movable member, a tension case fixed to an immovable member, a regular retainer engageable with an outer cable of the wire cable, and a slot formed in the tension case to extend in the longitudinal direction of the wire cable. The regular retainer engaged with the outer cable moves together with the outer cable by the tension applied to the wire cable through the length defined by the slot. The regular retainer is engaged with the outer cable in the state where a maximum tension is applied to the wire cable.
