回転電機の軸封装置。 In a rotating electrical machine for a rubber pump with a rubber impeller attached to the shaft end, a recess for attaching a slinger is formed in the center of the end bracket on the load side from which the shaft protrudes, and a drain hole communicating with this recess is opened on the side of the end bracket. A slinger having an extending portion whose peripheral edge extends downward is attached to the shaft passing through the recess, and a shaft seal portion on the bottom of the recess is made to protrude inside the downward extending portion of the slinger. A shaft sealing device for a rotating electric machine for a rubber pump, characterized in that a labyrinth structure is formed between a sealing portion and a slinger.
