にエンジンオイルが使用されている。A bearing 7 for receiving the rotor 4, a generator and a VP 9
An oil seal 8 that seals is installed inside the bracket 6. Further, in order to increase the holding force of the oil seal 8, there is a triangular groove (not shown) on the inner peripheral portion of the box portion of the bracket 6 for preventing the oil seal 8 from coming off (displacement). The oil seal 8 is adapted to withstand the lubricating oil pressure due to its holding force. The lubricating oil flows in the direction of the arrow, and engine oil is mainly used.

はオイルシール8よりの潤滑油漏れに至る。With this structure, the pressure applied from the VP 9 to the oil seal 8 during rotation is low because the lubricating oil flows, but when the rotation is stopped, for example, the engine power is transmitted to the generator to drive the generator. When a driving belt (not shown) is loosened and a failure such as breakage occurs, the lubricating oil pressure is applied but the rotation of the VP 9 is rarely stopped. In this case, the lubricating oil pressure is directly applied to the oil seal 8, the position of the oil seal 8 is displaced, and finally the lubricating oil leaks from the oil seal 8.
