Abstract
Abstract A filter for use in a gasoline tank comprises a filter body provided in the upper portion thereof with an insertion hole for permitting passage of a suction pipe possessing a radially bulged engaging portion, resilient arms extended directly from the upper edge of the filter body or from an upper lid to be fitted to the filter body, and a retaining member supported in position by the resilient arms. The suction pipe can be securely retained at a proper position on the filter without entailing any unwanted motion within the gasoline tank by simply inserting the suction pipe having the radially bulged engaging portion through the insertion hole of the filter body.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
In a filter for a gasoline tank, comprising a generally cup shaped filter body having a base and sidewalls containing a net stretched along the periphery thereof and a lid formed to cover the open end of said filter body and provided with an insertion hole for permitting a suction pipe to be inserted into the interior of said filter body and fastened therein, said suction pipe being provided intermediate the length thereof with an engaging portion; said lid further including a retaining member disposed substantially coaxially above said insertion hole and spaced from said lid, and at least a pair of resilient arms integrally attached to said lid and said retaining member for supporting in position said retaining member in spaced relation from said lid, said retaining member being adapted to resin said suction pipe when the free end of said suction pipe is telescoped through said retaining member and said insertion hole until said engaging portion of said suction pipe is moved into fast engagement with said retaining member; and means positioned within said filter body for moveably locating said suction pipe free end.
Claim 2
Dependent Claim
186 words
In a filter for a gasoline tank, comprising a generally cup shaped filter body having a base and sidewalls containing a net stretched along the periphery thereof and a lid formed to cover the open end of said filter body and provided with an insertion hole for permitting a suction pipe to be inserted into the interior of said filter body and fastened therein, said suction pipe being provided intermediate the length thereof with an engaging portion; said lid further including a retaining member disposed substantially coaxially above said insertion hole and spaced from said lid, and at least a pair of resilient arms integrally attached to said lid and said retaining member for supporting in position said retaining member in spaced relation from said lid, said retaining member being adapted to resin said suction pipe when the free end of said suction pipe is telescoped through said retaining member and said insertion hole until said engaging portion of said suction pipe is moved into fast engagement with said retaining member; and means positioned within said filter body for moveably locating said suction pipe free end.
Claim 3
Dependent Claim
78 words
A filter for gasoline tank according to claim 1, wherein said retaining member is composed of an upper ring and a lower ring which are vertically opposed in spaced relation to each other, said upper ring including means to make it expansible so as to permit said engaging portion formed on the suction pipe to be passed therethrough, and the space between said upper and said lower rings is adapted to receive and retain fast said engaging portion.
Claim 4
Dependent Claim
61 words
A filter for a gasoline tank according to claim 1 wherein said means for locating the suction pipe within the filter body include a plurality of axially extending circumferentially spaced support pieces which extend from the base of said filter body toward said open end and define a cavity spaced from the sidewalls and adapted to slidably accept said suction pipe.
Claim 5
Dependent Claim
42 words
A filter for a gasoline tank according to claim 3 wherein said resilient arms resiliently insure movement of said suction pipe to an optimum position relative to the base of said filter body and the gasoline tank in which it is utilized.
Claim 6
Dependent Claim
35 words
A filter for a gasoline tank according to claim 2 wherein said upper ring is radially relieved in at least one point to render it resiliently expandable to permit said engaging portion to pass therethrough.
