  • Oil strainer
    Patent number: 6814860
    Abstract: An oil strainer comprises upper and lower partial bodies, made of synthetic resin, joined together to form a roughly tube-shaped strainer main body, the interior of which is provided with a filter. The oil strainer has a flange section for attachment with bolts, and the flange section is provided with at least one bolt hole which passes through the interior of the roughly tube-shaped strainer main body. With this structure, it is possible to provide an oil strainer which can be installed on a small installation surface, which is able to reduce resin fatigue, and which can prevent impairment of the seal due to loosening of installation members.
