Abstract

Disclosed is a gearbox enabling to inhibit defective engagement between a first helical gear and a second helical gear even when a restraint torque is applied. The gearbox includes: the first helical gear; the second helical gear to engage with the first helical gear; a casing including a first member disposed in proximity to the first helical gear and a second member disposed in proximity to the second helical gear; a screw for fastening the first member with the second member, and disposed closer to the first helical gear than an engagement position between the first helical gear and the second helical gear and penetrating at least the second member; and a clip disposed closer to the second helical gear than the engagement position, and formed of a closed curve in such a manner that the first member end and the second member end are enclosed therein.
