Title: SIDE RAIL
Abstract:
This side rail (1) is configured to have: an outer peripheral surface (14) facing radially outward; an inner peripheral surface (13) facing radially inward; a first axial side surface (11) facing one axial side; and a second axial side surface (12) facing the other axial side and parallel to the first axial side surface (11). The side rail (1) has a chamfered section (30) located between the outer peripheral surface (14) and the second axial side surface (12). The chamfered surface (30) is formed as a tapered surface (30a) having a diameter gradually decreasing toward the second axial side surface (12) from a point on the outer peripheral surface (14), the point being located at an axial distance of 0.05 mm or greater from the first axial side surface (11) toward the second axial side surface (12). The tapered surface (30a) is configured to have: a first tapered surface (30a1); and a second tapered surface (30a2) provided between the first tapered surface (30a1) and the outer peripheral surface (14) and having smaller tilt angle relative to the axial direction than the first tapered surface (30a1).
