  • Resin-made air cleaner
    Patent number: 5755844
    Abstract: A resin-made air cleaner includes a hollow resin-made housing, a tubular element accommodated in the housing, a tubular projection, a gasket fitted around the tubular projection, and disposed between the tubular element and the tubular projection, a stopper for inhibiting the gasket from moving. The tubular projection is disposed on at least one of opposite end surfaces of the housing so as to project toward the inside of the housing. The stopper is disposed on the projection and/or the opposite end surfaces of the housing, on which the projection is disposed. This arrangement not only enables the increase of the resin content of the air cleaner, but also inhibits the gasket from coming off from the projection when the element is disassembled.
