の作用効果が得られた。 In order to achieve the above object, the present invention provides the structure of the above-mentioned hydraulic power transmission case, in which a housing chamber for the oil filter is provided within the transmission case and extends across the opposing case wall. An oil filter insertion port opening into the storage chamber is formed in one of the case walls, a gear oil intake port opening into the storage chamber is formed in the other case wall, and a gear oil storage in the transmission case. an oil outlet opening in the section, and an oil outlet opening in the outer wall of the one case wall extending between the pump and the insertion port, and an outer surface of the other case wall extending between the intake port and the outlet port, respectively. A plate as a member is attached, and a pump side oil passage and a gear oil intake passage are formed on the mating surfaces of these plates and the case wall. With this characteristic configuration, the following can be achieved. The effect was achieved.

略化できた。 That is, gear oil is supplied to one end side of the storage chamber formed across the opposing case wall through a gear oil intake path using the outer surface of the case wall,
While flowing from one end of the storage chamber to the other, the fluid passes through a filter during the flow, and is sent to the pump via a pump-side oil passage that utilizes the outer surface of the case wall. Therefore, oil can flow throughout the storage chamber to avoid stagnation, prevent early deterioration of oil and malfunctions caused by it, and can also supply oil to the entire area around the oil filter, thereby improving oil filtration. This makes full use of the surface area and allows for better oil filtration. In addition, since the oil passage is formed using the outer surface of the opposing case wall of the mission case, the structure and manufacture of the mission case can be simplified at the same time as the above-mentioned advantages.
