Abstract
To prevent grease released from a bearing from contaminating the inside of a distance measuring device.SOLUTION: A distance measuring device which measures a distance to an object by using incident light and reflection light generated by the incident light reflected by the object, includes a stationary part, a rotation part which rotates relative to the stationary part, and a bearing connected to the rotation part. The stationary part includes a lens cover at least a portion of which is disposed between the bearing and the rotation part.SELECTED DRAWING: Figure 2
