<p>A geared motor includes a drive source, a deceleration transmission mechanism which is connected to the drive source for decelerating and transmitting a rotation output of the drive source to an output part, a first case which fixes the drive source, a second case which forms a space for accommodating the drive source together with the first case and supports the deceleration transmission mechanism, and a third case which covers the deceleration transmission mechanism. A part of the deceleration transmission mechanism is formed with the second case in an integral manner. For example, the deceleration transmission mechanism includes a planetary gear mechanism which comprises a sun gear which transmits the rotation output from the drive source, a planetary gear which revolves around the sun gear while rotating, and an internal gear which is integrally formed on the second case and engages with the planetary gear.</p> |
