Document Type and Number:
Japanese Patent JP2019054674
Kind Code:
A
Abstract:
To fix a resin seal member and a cover member securely, while simplifying production process, in a motor including the resin seal member covering the stator.SOLUTION: The motor 2 of a pump device 1 includes a resin seal member 12 covering the stator 11, and a cover member 13 covering the resin seal member 12 from the output side L1. When assembling the cover member 13 to the resin seal member 12 from the output side L1 toward the anti-output side L2, protrusions 80 at four positions are passed to notches 13g-13j. When the cover member 13 is turned subsequently, the protrusions 80 engage with notches 13p-13s. Furthermore, at one of three positions of the notches 13g-13j, a rotation stop member 81 is inserted between a connection 13t and the outer peripheral surface of the resin seal member 12, and a locking claw 86 formed in the rotation stop member 81 is locked to a through hole 87 formed in the connection 13t, thus stopping rotation of the cover member 13.SELECTED DRAWING: Figure 1
