SPEED REDUCER AND CONSTRUCTION MACHINE
A speed reducer according to one aspect of the present disclosure includes: speed reducing units for decelerating a rotational driving force of an electric motor and transmitting the decelerated rotational driving force to a rotational driving unit; and a ring gear meshing with a gear decelerated by a speed reducing unit on the electric motor side in a direction of a rotational axis of the electric motor. The ring gear is provided with a water-cooling channel that communicates cooling water. The water-cooling channel includes a first groove having a small depth and a second groove having a larger depth and extends in a C-shape as the ring gear is viewed from the direction of the rotational axis. The ring gear is provided with a motor flange mounted to the electric motor. The motor flange is provided with an inlet port and an outlet port connected to the water-cooling channel.
