PURPOSE: To prevent coming off of a sleeve securely and obtain an inexpensive structure of a thrust roller bearing. CONSTITUTION: A sleeve 14 which is made of a synthetic resin and receives a load applied in the radial direction is fitted and held in an inner side of a first cylindrical section 6 formed in an inner peripheral fringe section of an inner wheel 2. A bottom face of an inward flange 20 formed at a top end of the first cylindrical section 6 is brought into contact with a top end face of the sleeve 14 to prevent coming off of the sleeve 14. The sleeve 14 is inexpensive because it can be made by axial drawing. |
