Abstract
The spiral advance/retreat actuation device includes a first strip material, a second strip material, an inner guide member as a strip material guide unit, an outer cylindrical wall, and a strip material storage container. The strip material storage container includes a first storage chamber that spirally stores a first strip material that has transitioned from a cylindrical configuration state to a separated state, and a second storage chamber that spirally stores a second strip material that has transitioned from a cylindrical configuration state to a separated state. The inner bottom surface of the first storage chamber and the inner bottom surface of the second storage chamber are sloped so as to descend as they move away from the axis.
