PURPOSE:To achieve reinforcement of a mission case in a transmission and more assured lubrication to a part to be lubricated, in a simple structure. CONSTITUTION:A power transmission gear 25 is provided on the inside of a mission case 2 storing a lubricating oil 28, while a lubricating oil guiding route 47 for receiving the lubricating oil 28 jumped up by the power transmission gear 25 and for letting the oil flow to a part to be lubricated, is provided on the upper part on the inside of the mission case 2. A protruded body 49 extending in the shaft direction of the power transmission gear 25 is formed by expanding a part of the ceiling wall 35 of the mission case 2 upward. The lubricating oil 28 jumped up by the power transmission gear 25 is guided to the inside of the lubricating oil guiding route 47 by the recessed groove 50 on the lower surface side of the protruded body 49. |
