Claims

[Scope of utility model registration request]

In a lubrication mechanism for a plain bearing on an oil pump rotating shaft, an oil groove that goes around the circumference is provided at a position in the axial direction that is a certain length from the end on the outer periphery of the bearing; An oil groove is provided that extends linearly in the axial direction from the end of the pump housing, and the axial oil groove is set to intersect with the circumferential oil groove in a T-shape. A bearing lubrication mechanism characterized in that a lubricating oil passage rises from a position of a circumferential oil groove of the bearing and is led linearly to a low pressure part provided in the pump housing.
