Abstract

A gear mounting portion (23c) of a rotating shaft (23A) includes a shaft portion (23e), with a D-shaped cross-section, engaged with a connecting portion (24e) of a gear (24) having a D-shaped cross-section; one flexible portion (23f) provided along the axial direction; and a retaining portion (23g) provided at a tip of the flexible portion (23f). The retaining portion (23g) protrudes outwards with respect to the shaft portion (23e), and the shaft portion (23e) is engaged with the connecting portion (24e) after the retaining portion (23g) has passed through a second hole portion (24y) of a hollow shaft (24a). The flexible portion (23f) remains bent while the retaining portion (23g) passes through the second hole portion (24y) of the hollow shaft (24a). Once the shaft portion (23e) engages with the first hole portion (24x) of the connecting portion (24e), the flexible portion (23f) ceases to bend and engages with the gear (24). As a result, without damaging the rotating shaft, the gear is reliably prevented from coming free from the rotating shaft.
