摘要： Disclosed is a driving gear (30) for a vehicle starter. Each tooth (32) of the driving gear (30) comprises a top chamfer (42) formed between a top land and a front end face (34) of the tooth (32) and a side chamfer (44) formed between a non-driving flank (40) and the front end face (34) of the tooth (32). The distance from a radially inner most point of the top chamfer (42) to the top land is in the range of 0.4 to 0.75 times the height of the tooth (32), the angle formed between the intersection line between the top chamfer (42) and the front end face (34) and a longitudinal central line of the tooth (32) is in the range of 125 to 1550, and the angle between the top chamfer (42) and the front end face (34) is in the range of 15 to 320.The driving gear of the disclosure is able to be engaged with a ring gear (20) on a fly wheel of a vehicle engine more quickly.
