摘要： A filter includes a case, filtering material housed within the case, a cover which covers the open end of the case and is non-rotatable relative to the case, and an annular fastener clamping the cover to the case. The case includes a large-diameter portion at an open end of the case, the large-diameter portion including a convexity forming an engagement tab. The cover has a concavity into which the convexity is received to prevent the cover from rotating relative to the case. Moreover, the cover includes a screw thread on the outer periphery thereof. The annular fastener has a screw thread on the inner periphery thereof mated with the screw thread on the outer periphery of the cover. On the other hand, the annular fastener has a small-diameter portion engaged with the large-diameter portion of the case by which engagement and mating of the screw threads the annular fastener secures the cover to the case. By preventing relative rotation between the cover and the case, the filter can be easily installed by being screwed onto a threaded member of an automotive engine or the like.
