Abstract: Disclosed is a fuel filter in which is disposed in a fuel suction port of a fuel tank or in a fuel line and used to filter the fuel. At least one of filter materials constituting the fuel filter is made into a multifunctional filter material having a function of trapping dust of different particle diameters in stages, by differing the diameter of the pores in the filter material from the primary side to the secondary side of the filter material so that the size of the pores decreases toward the secondary side.

Abstract: A fuel filter device includes a bag-shaped filter member and is adapted to be attached to communicate an inner space of the filter member with a fuel suction opening in a fuel tank. The filter member is configured in a multilayer structure. At least one layer of the filter member is configured to serve as an inhibition layer having a structure to prevent water in a fuel tank form coming into the inner space of the filter member by a pressure applied to the filter member when the water is frozen.

The filter body includes an upper surface part, and a lower surface part welded with the upper surface part at edges to form a bag shape. At least the lower surface part has a woven mesh outer layer part, a first inner layer part situated adjacent to the outer layer part and formed of a melt blown non-woven cloth, and a second inner layer part situated adjacent to the first inner layer part at a side opposite to the outer layer part. The second inner layer part is formed of a spun-bonded non-woven cloth. The upper surface part and the lower surface part are all made of polypropylene that is not soaked and swollen with fuel to thereby maintain a mesh size of the filter body without change.

Abstract: A fuel-filtering device includes a filter body having a bag shape and a communication hole, and is formed of a plurality of laminated filter layers bonded at rim portions by welding. The laminated filter layers include an outside filter layer formed of a woven mesh, an inside filter layer formed of a non-woven fabric, and at least one intermediate filter layer disposed between the outside filter layer and the inside filter layer and formed of a non-woven fabric. The inside filter layer has an average aperture diameter larger than that of the intermediate filter layers. The filter body is formed of at least one of a polyethylene fiber and a polypropylene fiber. The inside filter layer protects the intermediate filter layer and enhances a weld strength at the rim portions.

Abstract: A sliding assisting apparatus for assisting a sliding operation wherein a movable body slidably engaged with a base is slid between a first sliding position and a second sliding position includes sliders, a spring member, lock members and operation members. The sliders are engaged with the movable body and capable of sliding in the same one or more directions as the movable body. The spring member is capable of accumulating force in the sliding operation of the movable body and connecting the respective sliders together. The lock members are each capable of engaging with one of the sliders to exert the accumulated force on the slider, and disengaging from the slider to release the accumulated force from the slider. Operation members are each capable of engaging and disengaging with the lock member for engaging the lock member with a slider and disengaging a lock member from the slider.

Abstract: A sliding assisting apparatus includes a main body provided on a base or a movable body, and having a pair of sliders disposed in a case; lock members formed on the sliders; coupling parts provided on the case to couple/uncouple with the lock members; a forcing device provided between the two sliders to accumulate a biasing force when one of the sliders is slid to move away from the other; a pair of strikers provided on the base or the movable body; and a switch between a case restrained position and a case restraint released position. One striker is disposed between the first and second sliding positions to cause the movable body to slide toward the first sliding position, and a second striker is disposed closer to the second sliding position than the first striker to cause the movable body to slide toward the second sliding position.

Abstract: A filter member includes at least two non-woven layers, wherein one non-woven layer has air holes with an average diameter different from those of the other non-woven layer. Among the non-woven layers, the non-woven layer located on an inner side of the filter member has the air holes ranging from 1.7 ?m to 16.6 ?m, with the average diameter smaller than those of the non-woven layers located on an outer side of the non-woven layer. Also, the non-woven layers are formed with a melt blown method, so that the filtering slope becomes gentle. In the fuel filter device, it is possible to reduce clogging of the filter member as little as possible while improving the filtering accuracy of the filter member.

Abstract: A sliding assisting apparatus assists a movable body to move between a drawn-out position and a drawn-in position.
