Document Type and Number:
Japanese Patent JP3151282
Kind Code:
B2
Abstract:
PURPOSE: To easily replace a filter of a cleaner.
CONSTITUTION: A filter 9 is freely attachably and detachably housed in a case body 8 which is closed by a cover member 13. The filter is pressed on the cover member by an elastic member 14. On the cover member, a thread 12 screwing in a thread 11 in a place where the cleaner is to be fitted is formed. On the case body and the cover member are provided projections 17, 18 which are alternatively projected centering the threads in the radial direction and superimposed in the central axis direction to connect the case body and the cover member in the central axis direction. ON one of the case body side projection and the cover member side projection, a projection 23 for fixing the case body and the cover member in the circumferential direction is provided, engaged with the other projection in the circumferential direction of the threads. When replacing the filter, removing the mutual superimposition of the projections is sufficient for that work.
