でのパツキンの役目を果たし燃料漏れを防止している。A discharge vibro and a return vibrator 7 serving as fuel piping are welded to a flange 8, and the flange 8 is attached to the vibration absorbing member 4 by a wire-like stopper 9 so as to prevent fuel from leaking. The fuel pump 10 is attached to a bracket 11, and the bracket 11 is welded to the flange 8. Fuel is sucked in through the filter 12, and the fuel is pumped through the fuel pump l.
It passes through a discharge vibro and is sent to an engine (not shown). The operation of the above embodiment in which the fuel not used by the engine is returned to the fuel tank 1 through the return vibe 7 will be explained. fuel pump 10
vibrations and vibrations of the discharge vibro are transmitted to the flange 8, but since the flange 8 is attached to the fuel tank 1 via the vibration absorbing member 4, which is an elastic body, the metal between the fuel tank and the flange is transmitted to the flange 8. There is no contact and vibration transmission is prevented and suppressed. The vibration absorbing member 4 also acts as a seal around the bolt 5 to prevent fuel leakage.
また押え板８がこの様な形状となっている増白は、燃料

の振動吸収部材４とフランジ８の間の滑り止めである。The protrusion 114m of the vibration absorbing member 4 serves to prevent the stopper 9 from slipping. The convex s8& of the flange 8 serves to prevent slippage between the vibration absorbing member 4 and the flange 8 when the internal pressure of the fuel tank 1 increases.

きな曲面がとっである。The contact portion 1a of the fuel tank 1 with the vibration absorbing member 4 and the contact portion 8a of the presser plate 3 with the vibration absorbing member 4 are finished in curved shapes so as not to damage the vibration absorbing member 4. In particular, when the internal pressure of the fuel tank 1 increases, shear stress is applied to the contact portion 8a of the holding plate 8 to the vibration absorbing member 4, so a particularly large curved surface is required.

ている。The fuel passes through the suction vibrator 16 and is conveyed to the fuel pump via a rubber hose (not shown). The difference from the first embodiment is that the fuel pump is not attached to the flange 8;
The point is that the vibro 16 corresponds to the suction vibrator 16 of the fuel pump in the second embodiment, whereas it is the discharge vibro 16 of the fuel pump in the first embodiment. Further, in the second embodiment in which 10 is a fuel pump and E is an engine, although the amount of vibration transmitted to the fuel pump main body is small, the pulsation caused by fluctuations in the suction pressure of the fuel pump causes the suction vibrator 16 to vibrate. The vibration transmitted to the flange 8 is quite large.A vibration absorbing member 4 is provided to absorb this vibration, and prevents and suppresses the vibration from being transmitted to the fuel tank 1.

きれはよい。Next, a third embodiment, which is a slight modification of the second embodiment, will be described. This has a diaphragm structure as shown in Figure 4, and in this case, the vibration absorbing member 14 is attached to the flange 1.
8, is bonded with an adhesive that is gasoline resistant and has a sealing effect. Although wire-shaped fasteners 9 and adhesive are used to fix the vibration absorbing members 4 and 14 and the flanges 8 and 18 in FIG. 8 and FIG. The vibration absorbing members 4 and 14 are connected to the flange 8
and 18 may be burned. The point is that the vibration absorbing plates 4 and 14 can be fixed to the flanges 8 and 18 without leaking fuel.
