PROBLEM TO BE SOLVED: To reduce contact surface pressure of a cylindrical roller and a collar part, especially, contact surface pressure as a stage before reaching the maximum skew angleθMAX. SOLUTION: The contact surface pressure P shifts at a value lower than a bearing level P<SB>0</SB>causing abrasion on a contact part as a phenomenon where the contact surface pressure P rises at comparatively acute inclination in comparison with a skew angleθin a region of 0<θ≤θT but a critical skew angleθT is regulated to a small angle. That is, to restrain heating and abrasion of the contact part by reducing the contact surface pressure P by regulating the critical skew angle to the small angle. COPYRIGHT: (C)2004,JPO
