    • A shaft bearing member for supporting a shaft so that the shaft is rotatable has an inner circumferential face serving as a sliding surface. The, shaft bearing member includes an oil groove formed in the inner circumferential face so as to circumiferentially extend, and a plurality of narrow grooves formed on the inner circumferential face so as to extend at a predetermined angle relative to a rotation direction of the shaft from at least one of both widthwise sides of the oil groove toward an axial end side of the inner circumferential face with respect to the shaft. The narrow grooves guide a lubrication oil from the oil groove toward the axial end side with rotation of the shaft. The narrow grooves are shallower and narrower than the oil groove.
    • 用于支撑轴以使轴可旋转的轴承构件具有用作滑动表面的内周面。 轴承部件包括形成在内周面上的圆周方向延伸的油槽和形成在内周面上的多个窄槽,以相对于轴的旋转方向以预定角度延伸, 油槽的宽度方向侧的至少一方相对于轴相对于内周面的轴向端侧。 窄槽通过轴的旋转将润滑油从油槽引导到轴向端侧。 窄槽比油槽更浅,更窄。
