  "textContent": "A pipe member (45) is pushed into an inner periphery of a core (42) of an armature (38) to fix the pipe member (45) to the armature (38). The pipe member (45) is inserted over a fixed shaft (41). Bearing members (46) have a small hole (46a) and a large hole (46b) formed at their centers. Pipe member (45) ends are pushed into and fixed to the large diameter holes (46b). The fixed shaft (41) is inserted into the small holes (46a) to rotatably support the armature (38). A guide hole (52) is formed at the center of an impeller (36) of a pump unit (32), and is fitted to the bearing member (46), thereby the impeller (36) rotates while the impeller (36) is guided by the outer peripheral surface of the bearing member (46) which rotates integrally with the armature (38). Coupling protrusions (47) formed on the armature (38) are inserted, and engaged with engagement recesses (48) formed in the impeller (36) to transmit a rotation force of the armature (38) to the impeller (36).",
