Turning speed reducer for the turntable of an excavator
A shovel includes a turning drive unit. The turning drive unit includes a turning electric motor, a turning speed reducer configured to transmit the rotational driving force of the turning electric motor to a turnable body, a brake unit configured to maintain the turnable body in a state where the turning of the turnable body is stopped, and a case forming a space in which the turning speed reducer and the brake unit are lubricated with lubricant oil and accommodated. A recess is formed in part of the case that forms a bottom surface of the space.
