Abstract: A housing device 10 includes a movable pulley unit 20 and a movable pulley holding mechanism. The movable pulley unit 20 is provided so as to be movable relative to the housing 12 in an up-down direction, and is movable among a first position at which a long object is housed within the housing, and a second position at which the long object is pulled out from the housing. Whereas the long object is pulled out from the housing when the movable pulley unit 20 moves upward, the long object is housed in the housing when the movable pulley unit moves downward. Between the first position and the second position, the movable pulley holding mechanism switches between a state where the movable pulley is movable downward and a state where the movable pulley is immovable downward.

Abstract: The cord accommodation apparatus of the present application includes a housing and a pulley mechanism. The pulley mechanism includes a plurality of movable pulleys. The movable pulleys are attached to the housing so as to be able to move freely in an up and down direction, and a middle portion of an electrical cord is wound around the movable pulleys. At least one of the plurality of movable pulleys moves upwards with respect to the housing when the electrical cord is pulled out from the accommodation apparatus, while by contrast the electrical cord is accommodated in the accommodation apparatus by this movable pulley, that. has previously moved upwards, moving downwards.
