PROBLEM TO BE SOLVED: To provide a synchronizer ring, a clutch gear, and a sliding structure including them, capable of reducing catching characteristic of a clutch gear and a synchronizer ring while improving torque transmitting characteristic of the clutch gear and the synchronizer ring in a shift operation of a transmission.SOLUTION: A clutch gear 24 includes: a gear cone portion having a taper-shaped outer peripheral face 24-1 kept into contact with and slid on a taper-shaped inner peripheral face 22-1 of a synchronizer ring 22. An intersection angle &thetas;1 between an intersection line C1 of a plane including a rotating shaft CL of the clutch gear 24 and an outer peripheral face 24-1, and a rotating shaft CL, is within a range of 6.5-10°, and the outer peripheral face 24-1 is coated with an amorphous carbon coating film 31 within a range of 5-30% to the total length of the outer peripheral face 24-1 along the intersection line C1. |
