While fitting the shaft, a passage is formed between the inner periphery of the winding bush and the rotating shaft, and a sealing groove is formed around the bearing hole corresponding to the outermost end of the passage; In a vane pump in which a seal is installed in this seal groove and the passage is connected to a drain passage formed in the body, a recess is formed along the bearing hole, and a winding bush is fitted into the bearing hole. A vane pump in which the recess is separated from the bearing hole, a drill hole is formed at or near the deepest part of the recess, and a drain passage is formed by the recess and the drill hole.
