Title:
ELECTRIC FLUID PUMP
Document Type and Number:
WIPO Patent Application WO/2018/037596
Kind Code:
A1
Abstract:
Lubrication grooves 42A, 42B, which are formed in the inner peripheral surfaces of sliding bearings 27, 28, are formed as inclined grooves having a prescribed incline relative to a line segment C extending in the axial direction of the outer peripheral surface of a fixed support shaft 20. Because the lubrication grooves 42A, 42B are thereby inclined relative to the line segment C extending in the axial direction of the outer peripheral surface of the fixed support shaft 20, the fixed support shaft 20 is prevented from slipping into the inclined lubrication grooves 42A, 42B by a simple configuration, and the sliding bearings 27, 28 can thereby be prevented from vibrating.
