PROBLEM TO BE SOLVED: To provide a bearing capable of obtaining friction reduction effect and suppressing the total sum of flow-out oil amount.SOLUTION: In a slide bearing 1 in which half members 2 obtained by dividing a cylinder into two in parallel with an axial direction, are vertically disposed, a circumferential fine groove 3 is formed on an axial end portion of the lower half member 2, the fine groove 3 is composed of a bottom surface 3a, a first side wall 3b disposed between an axial outer end of the bottom surface 3a and an inner peripheral face 2a of the half member 2, and a second side wall 3c disposed between an axial inner end of the bottom surface 3a and the inner peripheral face 2a of the half member 2. The first side wall 3b is inclined to an axial outer side from the bottom surface 3a toward the inner peripheral face 2a of the half member 2, the second side wall 3c is inclined to an axial inner side from the bottom surface 3a toward the inner peripheral face 2a of the half member 2, and an inclination angle &thetas;1 to the bottom surface 3a of the first side wall 3b is larger than an inclination angle &thetas;2 to the bottom surface 3a of the second side wall 3c.SELECTED DRAWING: Figure 3 |
