体ポンプ及びモータ。 A conveying rotary body for conveying liquid is housed in the main body, and a rotary shaft coupled to rotate together with the conveying rotary body is provided. The oil seal is inserted through a large-diameter hole that is larger than the shaft hole and protrudes to the outside, and has a lip portion whose inner periphery comes into pressure contact with the outer periphery of the rotating shaft to prevent leakage to the outside along the outer periphery of the rotating shaft. is installed in the large-diameter hole, and a buffer member with an insertion hole for inserting the rotating shaft inside the large-diameter hole is detachably provided to form an inner chamber on the shaft hole side and an outer chamber on the oil seal side. The inner chamber is provided with a flow path that communicates with the bottom pressure side, and the inner periphery of the insertion hole of the buffer member is provided with a threaded groove that extends inward of the main body in the direction in which the rotating shaft rotates. .
