Abstract: A cover opening-closing device comprises a rod, a casing in which at least a portion of the rod is stored, a lock unit, an interlock mechanism, and a connection unit. The lock unit can rotate about a central axis line between a lock position, in which locking with the cover is possible, and a release position, in which locking is not possible. The interlock mechanism is configured so that the rotation of the lock unit and the displacement of the rod are interlocked. The connection unit is configured so as to connect the lock unit to the casing and to restrict displacement of the lock unit in the direction of the central axis line.

Abstract: A walking training system includes a leg orthosis fitted to a leg of a user, a pulling member coupled to the leg orthosis, a first drive mechanism configured to apply pull force to the pulling member, according to walking motion of the user, a holding device that holds the pulling member at a holding level, at a point between a coupling point of the leg orthosis and the first drive mechanism, and a second drive mechanism configured to change the holding level of the pulling member held by the holding device, according to the walking motion of the user.

Abstract: A housing device 10 includes a movable pulley 20, (first weights 18), and a guide mechanism. The movable pulley is movable among a first position at which the long object is housed within a housing 12, a second position at which the long object is pulled out from the housing, and a third position which is set between the first position and the second position. The long object is pulled out from the housing when the movable pulley 20 moves upward, and the long object is housed in the housing when the movable pulley moves downward. The first weights 18 are separated from the movable pulley when the movable pulley moves between the first position and the third position, and moves together with the movable pulley when the movable pulley moves between the third position and the second position.
