PROBLEM TO BE SOLVED: To provide a circulator for a bathtub capable of sucking bathtub water in, even when a filter cover is clogged, thereby maintaining a function of the circulator.SOLUTION: The circulator for the bathtub is composed of an outer cylindrical body 11 arranged in the outside of a sidewall 12 of the bathtub, and a fastening cylindrical body 20 tightly fixed to the outer cylindrical body 11 in the condition where the fastening cylindrical body is inserted from the inside of the bathtub into a through-hole 12a provided in the sidewall 12 of the bathtub. The fastening cylindrical body 20 is installed with a partitioning member 27 for partition-forming a suction flow passage for sucking the bathtub water from a suction opening part 40, and a delivery flow passage for delivering hot water heated by a water heater from a delivery opening part 34 into the bathtub. The filter cover 44 is attached onto an outer face of the partitioning member 27. A suction notch 55 is provided between a flow passage direction changing part 33 for changing directions of the suction flow passage and the delivery flow passage and an outer circumferential wall 27a of the partitioning member 27.
