Shovel and swiveling speed reducer
The invention provides a swiveling driving device and a swiveling speed reducer, which can immediately and accurately check lubricating oil after the operation of the swiveling driving device is completed. Provided is a shovel including a swiveling motor, and a swiveling speed reducer that reduces the rotational speed of an output shaft of the swiveling motor. The swiveling speed reducer includes a first gear mechanism; a first gear case that houses the first gear mechanism; a first oil check pipe that is disposed in the first gear case; a first communication portion that allows an inside of the first gear case and the first oil check pipe to communicate with each other; and a second communication portion that connects a position of the first gear case higher than a position where the first communication portion is connected, and a high position of the first oil check pipe.
