PROBLEM TO BE SOLVED: To provide a suction structure of a circulating bath in which dust in bath water can be surely removed even if attaching parts which are detached for removing the dust is forgotten. SOLUTION: An inside cover 16 is fixed to a suction bolt 15 (a piercing hole 13) and an outside cover 17 is removably attached to the suction port bolt 15 (the piercing hole 13) so as to cover the inside cover 16. Thus, the dust in bath hot water sucked in a suction body 14 via the piercing hole 13 can be surely removed by the inside cover 16 even if there is forgetting to attach removing parts called the outside cover 17 after detaching for removing dust attaching to the outside cover 17 and removing the dust.
