PROBLEM TO BE SOLVED: To adjust the projection direction of hot water piping (21) and (22) to a casing (10) on a hot water plug consisting of a pair of plug sections (11) and (12) that are connected to the tip of a pair of hot water piping (21) and (22) for communication, and a casing (10) that surrounds one portion of the plug sections (11) and (12) and hot water piping (21) and (22) and forms a long hole (30) where the hot water piping (21) and (22) can be inserted in parallel. SOLUTION: The hot water piping (21) and (22) is surrounded by a cylindrical piping cover (4) made of a flexible material so that it can be unified, at the same time the piping cover (4) can travel relatively in the longitudinal direction to the hot water piping (21) and (22), and the length of the long side in a long hole (30) is set larger than the length in a section in the parallel direction of the hot water piping (21) and (22) so that there is an interval margin between both the side ends of the bundle of the hot water piping (21) and (22) and both the ends in the direction of the long side of the long hole (30).
