PURPOSE:To make it possible to replace oil strainers, by forming a thread part in a support section provided in the oil suction section of a pump unit, and by engaging a shaft externally extending to hold an oil strainer, threadedly with the thread part. CONSTITUTION:A support section 22a supporting an oil strainer 23a through a shaft 23c is formed in the oil suction section of a pump unit 1 which is disposed in a pump casing 1 attached to a support frame 11. The shaft 23c carrying an oil strainer 23a is threadedly engaged with the support section 22a, and has its one end part piercing through a through-hole 28 in the pump casing 1 and externally projecting. Accordingly, when the oil strainer 23a is replaced with new one, it is sufficient to rotate the shaft 23c so that the oil strainer 23a is removed from the support section 22a, and is then pulled out from the through-hole 28 in the pump casing 1, thereby it is possible to facilitate the working thereof.
