The elastic seal member 15 includes the plurality of annular grooves 1 formed in the side wall portion of the first elastic seal member 14.
An annular seal member (for example, an O-ring) that is press-fitted into the through hole 13 of the cylinder head cover 12 while being fitted one by one into the cylinder head cover 7, the inner wall surface of the through hole 13 and the second elastic In order to form a liquid-tight seal structure between the seal member 15 and the seal member 15,
As shown in the figure, a penetration allowance δ is added. Therefore, the second elastic seal member 15 is fitted into the annular groove 17 of the first elastic seal member 14 holding the fuel pipe 11, and these elastic seal members 1
4 and 15 into the through hole 13, elastic deformation corresponding to the biting distance δ occurs in the elastic seal member, especially the second elastic seal member 15 (see Fig. 6B).
), a strong sealing function is generated between the fuel pipe 11 and the through hole 13 of the cylinder head cover 12 due to the restoring force against the elastic deformation.
On the other hand, the tightening band 16 made of a flexible material such as a metal sheet is fitted into a groove 19 formed in the upper part of the first elastic seal member 14 that protrudes from the upper opening of the through hole 13. The first
The first elastic seal member 14 is a tightening member that tightens the first elastic seal member to the fuel pipe 11, and uses the tightening force of the tightening screw 20 to create a liquid-tight seal structure between the first elastic seal member 14 and the fuel pipe 11. is forming.

An elastic seal member 14 press-fitted into the through hole 13
Since C is sealed between the second elastic seal member 15 and the cylinder head cover by C and 15, a liquid-tight seal structure S is formed at the press-fitted portion of the elastic seal member. Ru. On the other hand, as shown in FIG. 4, if for some reason the fuel pipe 11 has an eccentricity e shown by a dashed-dotted line or an inclination α shown by a dashed-double line, the first elastic seal member 14 Since the upper part is tightened to the fuel pipe 11 by the tightening band 16, the slit 18 does not open, and the liquid tightness between the first elastic seal member 14 and the fuel pipe 11 is maintained. The force for opening the slit 18 is prevented from spreading to the press-fitted portion of the elastic seal member. Further, since the annular second elastic sealing member 15 is press-fitted into the through hole 13 under the action of compressive force caused by the formation of the biting allowance δ, as shown in FIGS. 6A and 6B, Even if 〓C expands from C1 to C2 , the change in 〓C is completely absorbed by the elastic restoring force of these elastic seal members, especially the second elastic seal member 15. Therefore, fuel pipe 1
Even if eccentricity or inclination occurs in the first elastic seal member 14 and the fuel pipe 11, the tightening band 16 is tightened, and the second elastic seal member 14 and the through hole 13 are tightened. Since liquid tightness is maintained by press-fitting the elastic sealing member 15, the sealing function is not deteriorated, and the penetrating portion of the fuel pipe 11 can still maintain strong sealing performance.
