Gearbox, and method for manufacturing the same

摘要

A gear box includes a gear box body of a reducer to which a motor is mounted. The gear box body includes a worm, wheel holding section where a worm wheel of the reducer is held, and a motor holding section, where a part of the motor is contained, the motor holding section having a motor mounting opening. The motor holding section is configured such that a bottom of the motor holding section is provided in a region between a line L1 and a line L2. Here, the line L1 passes through the center C of the worm wheel holding section and is perpendicular to the axis line X of a motor shaft. The line L2 is a tangent line passing through an outer edge portion located near a circular outer peripheral wall of the worm wheel holding section on a motor side and is perpendicular to the axis line X of the motor shaft.

1. A gear box including a gear box body of a reducer to which a motor is mounted,
the gear box body including:
a worm wheel holding section where a worm wheel of the reducer is held;a motor holding section where a part of the motor is contained, the motor holding section having a motor mounting opening; anda first terminal integrally structured into the gear box such that at least part of the first terminal is embedded in the gear box body, the motor mounting opening is a space formed in the gear box body into which a second terminal of the motor is inserted, wherein the motor holding section is configured such that a bottom of the motor holding section is provided in a region between a line L1 and a line L2,
where the line L1 passes through a center of the worm wheel holding section and is perpendicular to an axis line of a motor shaft, and the line L2 is a tangent line passing through an outer edge portion located near a circular outer peripheral wall of the worm wheel holding section on a motor side and is perpendicular to the axis line of the motor shaft; and wherein the first terminal is so arranged as to be exposed from the motor mounting opening, and has a curved portion or notch so formed as to circumvent an inner peripheral wall of the worm wheel holding section, and has a bent part so formed as to circumvent a worm opening.
