- the receiving portion 4 is fixed to the inner surface of the bag-like body 1 so as to contact the elastic piece 35 formed in the conduit 3.
- the receiving portions 4 are respectively formed on the lower surface constituting portion 13 and the upper surface constituting portion 14 of the bag-like body 1 on the communication side of the bag-like body 1 with the conduit 3.
- the receiving portion 4 is made of a synthetic resin.
- the force receiving part 4 is configured to have an inner surface force of the bag-like body 1 and a protruding part shape protruding slightly.
- the one end force of the filter body 10 deployed at the location that becomes the lower surface constituting portion 13 is also in the length direction.
- the crush prevention parts 2 and 2 and the receiving part 4 of the two front and rear force stations are formed by insert molding using the developed filter body 10 as an insert.
- the receiving portions 4 are integrally formed on the surface of the filter body 10 which is the inner surface of the bag-like body 1 by insert molding using the developed filter body 10 as an insert.
- the crushing prevention portions 2 and 2 and the receiving portion 4 of the two power stations are respectively formed in the bag-like body in the lower surface constituting portion 13 and the upper surface constituting portion 14 of the bag-like body 1.
- the synthetic resin-made bone-like body 5 formed on the outer surface of 1 and the filter body 10 are integrated through the wall thickness.
- the strong bone-like body 5 is formed by the insert molding. The bone-like body 5 enhances the integrity of each layer of the filter body 10 having the laminated structure.
- the crush prevention part 2 provided in the lower surface constituent part 13 of the bag-like body 1 and the crush prevention part 2 provided in the upper surface constituent part 14 are adapted to abut each other inside the bag, Between the lower surface component 13 and the upper surface component 14 of the bag-like body 1, it is always possible to ensure an interval of a certain distance or more. That is, when the two collapsible prevention parts 2 and 2 are abutted with each other, the interval corresponding to the sum of the protruding dimensions of the two collapsible prevention parts 2 and 2 is secured at the formation position of the two collapsible prevention parts 2 and 2 of the bag-like body 1. be able to.
- the crush prevention part 2 provided in the lower surface constituent part 13 of the bag-like body 1 and the crush prevention part 2 provided in the upper surface constituent part 14 are provided in the concave part 20 provided in one of them in the other of these. So that it is faced with the protrusion 21 in place Therefore, it is possible to stably maintain a state in which an interval equal to or greater than the predetermined interval is secured. As a result, it is possible to prevent the bag-like body 1 from being deformed into an unexpected shape and causing inconveniences such as a subsequent change in the suction pressure of the fuel into the suction portion Tb.
- the conduit 3 connected to the suction part Tb is formed with an elastic piece 35 that comes into contact with the receiving part 4 fixed to the inner surface of the bag-like body 1, the bag-like body It is possible to prevent 1 from being deformed and narrowing, closing, or dripping the communication portion between the conduit 3 and the bag-like body 1.
- the lower surface portion 13 of the bag-like body 1 lifted by the contact of the bag-like body 1 with the tank bottom surface Ta can be supported inside the bag of the bag-like body 1 by the elastic piece 35, and the bag-like body 1 becomes the tank.
- the bottom surface Ta can be contacted with a certain force.
- the elastic piece 35 comes into contact with the receiving portion 4, the situation where the coasting piece 35 directly contacts the filter body 10 constituting the bag-like body 1 and damages the filter body 10 that is applied. It will not cause.
- the crushing prevention part 2 provided in the lower surface constituting part 13 of the bag-like body 1 and the crushing prevention part 2 provided in the upper surface constituting part 14 are fitted so that the protruding part 21 can be slidably moved in the recessed part 20. Since it is placed in a state where it can be brought into contact with each other, it is likely to cause a gap between the lower surface constituent portion 13 and the upper surface constituent portion 14 of the bag-like body 1 in this sliding movable direction. Even if a force is applied to the bag-like body 1, this deviation can be absorbed to some extent, and when such a force is applied, the bag-like body 1 can be prevented from generating wrinkles.
- a strong sliding movement occurs when the bag-like body 1 comes into contact with the tank bottom surface Ta.
- the bag-like body 1 should not be wrinkled. And so on.
