PROBLEM TO BE SOLVED: To provide a lubrication device capable of raising an oil level in a housing of an electric motor by using a simple configuration.SOLUTION: A lubrication device for a front motor 2 is mounted to a vehicle having an engine 3 and the front motor 2, includes an oil pan 19 for storing lubrication oil in a lower part in a housing 10, and lubricates a front bearing 15 and a rear bearing 16 for supporting a motor shaft 11 disposed in the housing 10 by using the lubrication oil supplied into the housing 10 by a hydraulic pump. The lubrication device includes an introduction passage 30 for introducing exhaust gas of the engine 3 into the oil pan 19. Exhaust gas is introduced into the oil pan 19 through the introduction passage 30 to cause the lubrication oil stored in the oil pan 19 to bubble and thus, the liquid level of the lubrication oil is raised to lubricate the front bearing 15 and the rear bearing 16.SELECTED DRAWING: Figure 2

    【課題】簡単な構成で電動機のハウジング内の油面の上昇を可能とする潤滑装置を提供する。【解決手段】エンジン3及びフロントモータ2を備えた車両に搭載され、ハウジング10内の下部に潤滑油を貯留するオイルパン19を有し、油圧ポンプによりハウジング10内に供給された潤滑油によって、ハウジング10内に配置されているモータシャフト11を支持するフロントベアリング15及びリヤベアリング16を潤滑するフロントモータ2の潤滑装置であって、オイルパン19内にエンジン3の排気を導入する導入路30を備え、導入路30によってオイルパン19内に排気を導入して、オイルパン19内に貯留している潤滑油を泡立たせ、当該潤滑油の液面を上昇させ、フロントベアリング15及びリヤベアリング16を潤滑する。【選択図】図2
