Title:
NEGATIVE PRESSURE PUMP
Document Type and Number:
Japanese Patent JP3769272
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase a reliability by effectively preventing a rotating shaft from being tilted in a negative pressure pump in which a rotor is connected to the rotating shaft rotatably pivoted on a pump housing so as to be non-rotatable relative to each other, a driven wheel is fixed to the projected end part of the rotating shaft projected from a cover member through the cover member of the pump housing, and an endless transmission member is wrapped around the driven wheel.
SOLUTION: This negative pressure pump is formed in such a manner that a flange part 26a extending to the radial outer side of the rotating shaft 26 is formed on the rotating shaft 26 between the driven wheel 27 and the cover member 40, and a cover 50 holding the flange part 26a in the clearance thereof from the cover member 40 from both axial sides is installed on the cover member 40.
