PROBLEM TO BE SOLVED: To provide the needle roller bearing with a retainer which provides the required size easily without changing a fundamental design to the change of the shaft diameter etc. or the roller diameter. SOLUTION: A plurality of pieces is formed continuously in the circumferential direction as one piece 3 which retains a needle roller 1 and a retainer 2 to hold this to the axial circumference enabling free rotation and the pitch P to the circumferential direction between pieces is made intoΔdxπin the needle bearing with retainer which the size unit of the pitch diameter is predetermined by minimum unitΔd. For example, Pitch P isπ[mm] ifΔd is 1 mm. If the number of piece is prepared at a the rate of one piece/Δd according to the pitch circle diameter predetermined by the size unit ofΔd, the needle bearing with retainer is easily manufactured suitable for the optional pitch circle diameter.
