Claims

[Scope of utility model registration request]

Inside the transmission case, there is an input shaft, an idler gear attached to the input shaft via a bearing, and an idler gear inserted into the hollow part from the open end of the cylindrical hollow part at the end of the input shaft. It includes a cylindrical oil guide and a lubricating oil supply system that lubricates the bearing by flowing lubricating oil into the cylindrical hollow part through the oil guide, and the lubricating oil supply system lubricates the bearing. A ring-shaped oil seal is provided between the outer peripheral surface of the guide, the outer peripheral part of the oil seal is press-fitted along the inner peripheral surface of the cylindrical hollow part, and the rubber lip of the oil seal is fixed to the inner peripheral surface of the cylindrical hollow part. A transmission with an oil seal, characterized in that the oil seal is in elastic sliding contact with the outer peripheral surface of a cylindrical oil guide.
