    Abstract: PROBLEM TO BE SOLVED: To suppress shortage of lubricating oil supplied to a predetermined object to be lubricated.SOLUTION: A power transmission device comprises a catch tank 80, an oil path 82 which supplies lubricating oil in the catch tank 80 to a bearing 62a, a top part 21b which receives lubricating oil raised by a differential ring gear 65 to guide the lubricating oil to the catch tank 80, and an oil path 84 which guides lubricating oil discharged from an oil pump to the catch tank 80. Thus, the shortage of lubricating oil supplied to the bearing 62a can be suppressed even when either the amount of lubricating oil raised by the differential ring gear 65 to reach the catch tank 80 by way of the top part 21b or the amount of lubricating oil discharged from the oil pump to be guided to the catch tank 80 through the oil path 84 is small.

    Abstract: A housing (25) of a gear device (21) houses a plurality of gears (23,24) and a lubricant (L). On at least one side surface (32,52) of at least one gear (24), an extended projection (58,61) is provided. On a side surface (57,60) of the housing (25) facing the side surface (32,52) of the gear (24), an extended projection (59,62) is provided. The extended projection (58,61) of the gear (24) and the extended projection (59,62) of the housing (25) extend in a direction (R,D2,D3) crossing the circumferential direction (C) of the gear (24). When viewed along an axial direction (S) of the gear (24), according to rotation of the gear (24), the extended projection (58,61) of the gear (24) and the extended projection (59,62) of the housing (25) partially face each other in the axial direction (S) and form facing portions (67a and 67b,74a and 74b). A lubricant holding portion (100) is formed between the facing portion (67a and 74a) of the extended projection (58,61) of the gear (24) and the facing portion (67b and 74b) of the extended projection (59,62) of the housing (25).
