Abstract: A case holding mechanism includes a holding member and a member to be held thereby, one being mounted to the case and another to a body to which the case is to be held. The member to be held includes a first pair of parallel guide portions and another pair of parallel guide portions perpendicular to the one paired guide portions. The holding member disposed to be movable with respect to the guide portions therealong in a state restricted in thickness direction of the guide portions and adapted to hold the member to be held. The holding member includes a pair of slide portions slidable along outer surfaces of one paired guide portions, a lock portion extending between the paired slide portions in parallel with the one paired guide portions and engaged with the other paired guide portions, and a base portion connecting the slide portions and the lock portion.

Abstract: A canister for treating evaporated fuel includes a casing which is provided with a fuel vapor inlet, a purge port and a port communicating with atmosphere and in which an adsorbent is accommodated, an air passage disposed inside the casing so as to communicate with the atmosphere communication port, the air passage having a shape for flowing the sucked air in a zigzag manner in the casing, and a filter element arranged between the air passage and the adsorbent disposed inside the casing.

Abstract: A canister having a liquefied fuel treating function capable of flexibly coping with layout restrictions without the need to bend the purging path in the middle. The canister having the liquefied fuel treating function includes a liquid storing case having an introducing path communicating with a fuel tank, and a purging path communicating with air inlet pipes of an engine; and a sucking path, provided in the liquid storing case, and sucking the liquefied fuel stored in the liquid storing case; which sucks up the liquefied fuel onto the purging path side by use of the flow of a fluid through the purging path; wherein the sucking direction of the liquefied fuel within the sucking path is caused to substantially agree with the flow direction of the fluid in the purging path.

Abstract: A fuel vapor capturing canister includes a cylindrical casing having a communicating hole which is formed at one end so as to communicate with the atmosphere and another communicating hole which is formed at the other end so as to communicate with a fuel tank and an intake system of an engine. An adsorbent is accommodated in the casing so as to form at least one layer. A pair of partitioning plates partition the adsorbent layer longitudinally of the casing. A deflecting plate is disposed between the partitioning plates so as to protrude from an inner wall face of the casing inwardly of the same. The partitioning plates are open in the vicinity of sides of the deflecting plate respectively.

Abstract: A fuel vapor capturing canister includes a casing formed into the shape of a cylinder and accommodating an adsorbent material. A partition member divides the activated carbon into lower and upper layers. The partition member includes a cross rib and upper and lower walls sandwiching the rib. One of four pieces of the cross rib is connected to the inner peripheral wall of the partition member. Two chambers located at both sides of the piece connected to the inner peripheral wall of the partition member communicate with each other through a communicating path defined between the other pieces of the rib and the inner peripheral wall of the partition member. One of the two chambers has in its underside openings communicating with the lower activated carbon layer while the other chamber has in its top openings communicating with the upper activated carbon layer. The fuel vapor flows between the two layers of activated carbon.

Abstract: A fuel vapor capturing canister includes a casing formed into the shape of a cylinder and accommodating an adsorbent material and a plurality of partition plates each formed of an impermeable material. The adsorbent material accommodated in the casing has one of two faces communicating with the atmosphere and the other face communicating both with a fuel storage system and an intake system of an engine. The partition plates are disposed in the casing so as to divide the adsorbent material into a plurality of layers. The partition plates has respective communicating holes formed so as not to lie one above another. This arrangement of the partition plates lengthens a path of fuel vapor passing through the activated carbon layers. Since the distance of flow of the fuel vapor in contact with the adsorbent material is thus increased, the fuel component adsorbing efficiency can be improved.
