ABSTRACT:
A strainer includes a filter which is easily detachable without the possibility of fluid leakage. The strainer has a housing defining a bore and is formed with a fluid inlet and outlet, and an end plate formed with a circular hole and cutouts provided along the edge of the circular hole, opposite to each other. A closure member is rotatably mounted in the bore of the housing and is formed with a passage through which the inlet and the outlet can communicate with each other, and a filter mounting hole. A filter is detachably inserted in the filter mounting hole. It has a flange and a knob formed with a protrusion. The edge of the circular hole is sandwiched between the protrusion and the flange. By turning the knob, the closure member can be turned to a position where it closes both the inlet and outlet. By pulling the knob in this state, the filter can be pulled out of the filter mounting hole for cleaning or replacement.
