Drive gear for a fishing reel

A drive gear for a fishing reel with a disc portion 30 having a rotational axis X2, and a gear tooth 31 protruding from a side surface on an outer peripheral side of the disc portion 30 in a direction in which the rotational axis X2 extends. The gear tooth 31 has a part 32 and an extended part 33 extending radially inward from the body part 32. A first angle a11 formed by a cylindrical surface CP1 around the rotational axis X2 passing through an axially outer surface of the body part 32 and a radially-inner surface of the extended part 33 is larger than a meshing pressure angle. The ratio of the first edge B1 of each tooth surface of the pair of tooth surfaces (31a, 31b) to the respective second edge B2 may be 1.28 or more. The gear arrangement is intended to improve rotational sensation and suppress abnormal noise generated while rotating.
