PROBLEM TO BE SOLVED: To prevent the deformation of a bearing sleeve in simple construction. SOLUTION: On a bearing holding portion 12a of a bearing holder 12 for applying clamp fitting such as press-in or shrink fitting to the bearing sleeve 13 formed of a porous oil retaining bearing member, a locking supplementary means 20 is provided for supplementarily locking the bearing sleeve 13 in the axial direction to prevent the slip out of the bearing sleeve 13. Thereby, clamp fitting interference such as press-in interference can be reduced to suppress the deformation of the bearing sleeve 13. COPYRIGHT: (C)2005,JPO&NCIPI
