PROBLEM TO BE SOLVED: To restrain a violence phenomenon by supply of fire extinguishing pressure water, and prevent a kink and excess pullout by arranging a frame body being a pullout port of a shape keeping hose on an opening part surface of a housing part for winding/housing the shape keeping hose so as to be elastically supported by plural long size elastic bodies. SOLUTION: A housing body 1 of a shape keeping hose H has a front surface side-opened box shape having a back face plate part, a side plate part 3 and a housing part 4, and a frame body 6 being a pullout port of the shape keeping hose H is arranged on a front side opening part surface of the housing part 4. In this frame body 6, one end is locked on an outer peripheral part of the frame body 6, and the other end is elastically supported by plural long size elastic bodies 7 locked on four-corner parts of the side plate part 3 of the housing body 1. This constitution can restrain a violence phenomenon by tensile force of the long size elastic bodies 7 stretched on the back face plate part, the side plate part 3 and the opening part surface for forming the housing part 4 when supplying fire extinguishing pressure water to the shape keeping hose H by opening of a fire hydrant valve B at fire time.
