Abstract

A power transmission apparatus (100) is provided, including: a case (41, 42) having a first oil storage (44) configured to store oil at a bottom thereof; a rotating body rotatably housed in the case (41, 42) and having a second oil storage (59) configured as an approximately cylindrical rotating body for transmitting power and configured to store oil therein; and an introducing portion (58) configured to introduce oil from the first oil storage (44) into the second oil storage (59).

Description

technical field [0001] The invention relates to a power transmission device which transmits power by using a rotating body rotating inside a casing. Background technique [0002] A device for lubricating with oil splashed by gears is conventionally known. Such a device is described in Patent Document 1, for example. The device described in Patent Document 1 includes a storage section for storing lubricating oil in a housing, a gear storage section for storing gears, and a partition section for partitioning the storage section and the gear storage section. In this device, the oil splashed by the gears is stored in the reservoir and the oil level in the gear housing is lowered, thereby reducing the stirring resistance due to the gears. [0003] However, in the device described in Patent Document 1, the gear storage part and the storage part are partitioned by the partition part inside the casing, so the size of the device is increased. [0004] prior art literature [0005...
