A first embodiment of the present invention will be described with reference to FIGS.
Reference numeral 20 in FIG. 1 denotes a fuel tank (corresponding to a member to be attached according to the present invention), which comprises an upper tank 20A that forms the upper half of the fuel tank 20 and a lower tank 20B that forms the lower half. Each of the upper tank 20A and the lower tank 20B is formed by pressing a thin metal plate into a box shape, and the upper tank 20A is opened downward and the lower tank 20B is opened upward. At the opening edges of both the upper and lower tanks 20A and 20B, outward joint flanges 21 and 24 are provided over the entire circumference.

  As shown in FIG. 6, the fuel tank 20 is integrally coupled by welding in a state where these joint flanges 21 and 24 are abutted. In this embodiment, the upper-side joining flange 21 of both the joining flanges 21 and 24 has a partly protruding amount from the tank body as compared with the lower-side joining flange 24, and the holding described below is performed. A pair of mounting seats 22 and 23 for mounting the tool 30 are formed, and insertion holes 22A and 23A are formed there.

The outer surface of the fuel tank 20 is painted to prevent damage to the fuel tank 20 and to improve corrosion resistance. In the present embodiment, the coating is applied to the entire fuel tank 20 by spraying a synthetic resin (for example, polyvinyl chloride resin) paint, whereby a cushioned outer skin 27 is formed on the outer surface of the fuel tank 20. It is formed. The thickness of the outer skin 27 is approximately 1 mm.
Moreover, 10 and 11 in FIG. 1 are fuel piping (equivalent to the attachment member of this invention). In the present embodiment, the fuel pipes 10 and 11 are made of metal, and one large-diameter pipe 10 and a small-diameter pipe 11 sandwiched therebetween are a pair.

  Next, a holder 30 (corresponding to the holding member of the present invention) 30 for fixing the fuel pipes 10 and 11 to the fuel tank 20 will be described. The holder 30 is made of synthetic resin and includes a pair of left and right substrates 32 and 33 corresponding to both mounting seats 22 and 23 of the joining flange 21 as shown in FIG. A part (upper half in FIG. 3) is constructed by the connecting plate 34. Side walls 35 are erected on the outer circumferences of the substrates 32 and 33 and the connecting plate 34 in the vertical direction over the entire circumference.

Engaging portions 41 and 45 for fixing the fuel pipes 10 and 11 are provided on the outer side of the connecting plate 34 (lower side in FIG. 3) and between the left and right substrates 32 and 33. Yes.
Three engaging portions 41, 45 are formed in parallel on the outer surface side of the side wall of the connecting plate 34, and among these engaging portions, the engaging portions 45 on both the left and right sides are for the small diameter pipe 11. On the other hand, the central engaging portion 41 is for the large-diameter pipe 10. If it demonstrates concretely, the center engaging part 41 makes | forms the cyclic | annular form (C-shaped cross section) which a part of circumferential direction opens. Guide portions 41B bent outward are formed at the tip portions of the left and right annular pieces 41A constituting the engaging portion 41. As shown in FIG. 9, when the large-diameter pipe 10 is pushed in from the side of the engaging portion 41, both annular pieces 41 </ b> A expand to allow the large-diameter pipe 10 to be pushed in, and the large-diameter pipe 10. Is pushed into the engaging portion 41, both annular pieces 41A are elastically restored and elastically contact the outer periphery of the pipe to hold the large-diameter pipe 10.

On the other hand, the left and right engaging portions 45 are mainly composed of a pair of engaging pieces 46 and 47 extending in parallel with the width direction of the connecting plate 34 (vertical direction in FIG. 9). Both engagement pieces 46 and 47 are formed so as to be able to bend, and the protruding height from the side wall 35 is different on the left and right, so that the outer engagement piece 46 has a larger protruding dimension than the inner engagement piece 47. . Each of the locking pieces 46 and 47 is provided with a pair of abutting projections 46B and 47B near the proximal end, and a pair of claw portions 46A and 47A at the tip. Further, an abutting protrusion 35 </ b> C is provided on the outer surface of the side wall 35. As shown in FIG. 9, when the small-diameter pipe 11 is inserted into the engaging portion 45, the small-diameter pipe 11 comes into contact with the abutting protrusions 35 </ b> C and 46 </ b> B, and the claw portion 47 </ b> A comes into contact with the outer peripheral surface of the small-diameter pipe 11. As a result, the small-diameter pipe 11 is held in the retaining state.
In the present embodiment, the claw portion 46A and the abutting projection 47B are both separated from the small diameter pipe 11, but the engaging portion 45 has a different diameter (larger diameter than the small diameter pipe 11). ), The claw portions 46A and the abutting protrusions 47B come into contact with the pipe.

  Further, on both the left and right sides of the connecting plate 34, cantilevered bending pieces 34A extending in the horizontal direction are provided. The bent piece 34A is formed by cutting out the connecting plate 34 into a U-shape and then raising it, and as shown in FIG. 5, the leading end of the bent piece 34A is on the back side of the connecting plate 34 (the lower side in the figure). This is a setting that protrudes more. The back side of the connecting plate 34 is the side facing the joining flange 21 when assembled, and the flexure piece 34A can be elastically contacted with the top surface of the joining flange 21.

  Further, as shown in FIG. 3, holding plates 52 and 53 having substantially the same width as the substrates 32 and 33 are formed outside the side walls 35 of the substrates 32 and 33 (lower side in the figure). , 33 and both pressing plates 52, 53 are connected by hinges 57 (molded integrally). A pair of left and right hinges 57 are provided on the left and right edge portions of each of the substrates 32 and 33, and the thickness of the hinges 57A and 57B is alternated along the length of the hinge 57 as shown in FIG. Is formed. Thus, by partially reducing a part of the wall thickness, the holding plates 52 and 53 can be easily folded back toward the substrates 32 and 33.

  The holding plates 52 and 53 are flat, and the mounting seats 22 and 23 of the fuel tank 20 are sandwiched between the substrates 32 and 33 as shown in FIGS. The pressing plates 52 and 53 and the substrates 32 and 33 are provided with a holding pressure holding portion 60 that can hold the mounting seats 22 and 23 between them. More specifically, a shaft portion 65 having a substantially square cross section is suspended from a central portion on the back surface side (lower side in FIG. 10) of the substrates 32 and 33. A tapered guide portion 67 is formed on the distal end side of the shaft portion 65.

  On the other hand, when the presser plates 52 and 53 are close to the tips of the presser plates 52 and 53 and the presser plates 52 and 53 are folded back toward the substrates 32 and 33, the shaft portion 65 can be inserted just into the position facing the shaft portion 65. An opening 61 having a size is provided. The opening 61 has a horizontally long shape, and a pair of elastic lock pieces (corresponding to the lock portion of the present invention) 62 are provided to face both left and right opening edges. As shown in FIG. 10, both elastic lock pieces 62 are formed so as to be inclined in the insertion direction of the shaft portion 65, and the shaft portion 65 is inserted into a gap between the free ends.

  Lock teeth (corresponding to the engaging portion of the present invention) 66 that can be engaged with the elastic lock piece 62 are formed on the outer wall surfaces on the left and right sides of the outer wall surface of the shaft portion 65. As shown in FIG. 10, the lock teeth 66 are symmetrical and have a sawtooth shape, that is, a plurality of stages are formed along the length direction of the shaft portion 65. These lock teeth 66 are formed at a constant pitch, and the elastic lock pieces 62 are selectively locked thereto so that the holding positions of the pressing plates 52 and 53 with respect to the shaft portion 65 are set in the axial direction (length) of the shaft portion 65. Direction).

By the way, although the pitch of the lock teeth 66 of this embodiment is set to 1 mm or less, this is due to the following reason.
The joining flange 21 has outer skins 27 on the upper surface side and the lower surface side, respectively, but since this is caused by spraying, the thickness may vary by several millimeters in total. If there is no adjustment function by the lock teeth 66, this variation becomes the shakiness of the holder 30 and the fuel pipes 10 and 11 as it is, but since the adjustment pitch by the lock teeth 66 is set to 1 mm or less, it is always The amount of play of the holder 30 relative to the fuel tank 20 can be set to 1 mm or less.

  In addition, as shown in FIG. 13, the lock teeth 66 are set in all nine stages, and this is a reinforcing plate in addition to the mounting seats 22 and 23 between the substrates 32 and 33 and the holding plates 52 and 53. This is in consideration of the case where another member such as 80 is interposed.

  Further, an identification protrusion 68 is formed on the outer peripheral wall (the outer peripheral wall on the left side shown in FIG. 6 and on the side opposite to the side where the hinge 57 is located) on the distal end side of the shaft portion 65. The identification protrusion 68 is for confirming whether or not the pressing plates 52 and 53 are locked to the shaft portion 65, and the pressing plates 52 and 53 are normally locked to the shaft portion 65. When in the state, the identification protrusion 68 is set to be exposed from the pressing plates 52 and 53. Therefore, the assembly operator can determine whether or not the pressing plates 52 and 53 can be locked to the shaft portion 65 by visually observing the identification protrusion 68.

  Next, a procedure for fixing the fuel pipes 10 and 11 to the fuel tank 20 will be described. First, the holder 30 is set in a posture in which the shaft portion 65 faces downward, and then the holder 30 is attached to the mounting seat 22 of the fuel tank 20 while the shaft portion 65 is aligned with the insertion holes 22A and 23A of the fuel tank 20. , 23 from the upper surface side, and both shaft portions 65 are inserted into the respective insertion holes 22A, 23A. When the shaft portion 65 is inserted through the insertion holes 22A and 23A, this time, one of the pressing plates 52 and 53 is turned approximately 90 degrees toward the back side of the mounting seats 22 and 23. Let me sing. Thereafter, alignment is performed so that the elastic locking pieces 62 of the pressed holding plates 52 and 53 face the shaft portion 65 of the substrates 32 and 33. When the alignment is completed, the pressing plates 52 and 53 are pushed toward the mounting seats 22 and 23. Then, the shaft portion 65 is inserted into the gap between the free end portions of both elastic lock pieces 62, and the distance between the opposing surfaces of the substrates 32 and 33 and the pressing plates 52 and 53 is reduced. During the pushing operation, the elastic lock piece 62 is pushed in while being expanded along the inclination of the teeth of the lock teeth 66, so that the pushing operation is allowed.

Eventually, when the pressing plates 52 and 53 are pushed down to the position where they come into contact with the lower surfaces of the mounting seats 22 and 23, that is, the surface of the outer skin 27, the further pressing operation is restricted, so that the operator can Know that 53 has been fully pushed. Thereafter, when the holding plates 52 and 53 are released, the elastic lock piece 62 is slightly returned to the tip end side of the shaft portion 65 and is engaged with the lock teeth 66 of the corresponding step. Thereafter, the same pressing operation is performed on the remaining other pressing plates 52 and 53.
Accordingly, the joining flange 21 of the fuel tank 20 is sandwiched between the substrates 32 and 33 and the pressing plates 52 and 53, and the holder 30 is fixed to the fuel tank 20. Then, if it inserts in the fuel piping 10 and 11 with respect to the engaging parts 41 and 45 of the holder 30, respectively, each engaging part 41 and 45 will elastically displace and will permit insertion operation of the fuel piping 10 and 11. At the same time, after the insertion operation is completed, the fuel pipes 10 and 11 are held again. Thus, the fuel pipes 10 and 11 are fixed to the fuel tank 20.

  As described above, according to the present embodiment, the lock teeth 66 are formed in a plurality of stages, and the elastic lock pieces 62 are selectively locked thereto, whereby the locking positions of the pressing plates 52 and 53 with respect to the shaft portion 65 are pivoted. The axial direction (length direction) of the portion 65 can be adjusted. Therefore, even when the entire thickness including the outer skin 27 of the joining flange 21 varies, the holder 30 and the fuel pipes 10 and 11 can be held in the fuel tank 20 without rattling. Further, even in the case of a configuration in which other members such as the reinforcing plate 80 are interposed in addition to the mounting seats 22 and 23 between the substrates 32 and 33 and the pressing plates 52 and 53, the holder 30 is left as it is. It can be applied.

Further, the connecting plate 34 is provided with a flexure piece 34A, which is configured to be elastically contacted with the joining flange 21, so that even if the lock positions of the holding plates 52 and 53 are adjusted, the holding plate 30 and Even if there is a slight rattling between the fuel tank 20 and the fuel tank 20, the slight rattling can be suppressed.
In addition, since the holder 30 is integrally formed, the number of parts does not increase, and the elastic lock piece 62 is locked to any one of the lock teeth 66 regardless of the thickness of the joining flange 21. Since it is a structure, it does not cause a lock failure.

<Embodiment 2>
The lock structure of the pressing plates 52 and 53 with respect to the shaft portion 65 in the first embodiment is based on a stepped lock structure in which a plurality of lock teeth 66 are provided on the shaft portion 65 and the elastic lock pieces 62 are selectively locked thereto. However, in the second embodiment, the lock structure is continuously changed, and the other configurations are the same as those of the first embodiment. Therefore, the same parts are denoted by the same reference numerals and the description thereof is omitted. It shall be.

  As shown in FIG.14 and FIG.15, in Embodiment 2, the lock tooth | gear is not formed in the outer periphery at the side of the axial part 70, but the surface is flat. On the other hand, the elastic lock pieces 75 formed on the holding plates 52 and 53 are configured by a pair facing each other in the same manner as in the first embodiment. In the second embodiment, the elastic lock pieces 75 are formed by bending a flat plate material. The lock piece 76 is inserted into the holding plates 52 and 53. Specifically, the proximal end portion of the lock piece 76 is embedded in the resin layer, while the distal end portion of the lock piece 76, that is, the portion that is locked to the shaft portion 70 is exposed from the resin layer. .

As in the first embodiment, the elastic lock piece 75 is slightly inclined with respect to the insertion direction of the shaft portion 70. When the elastic lock piece 75 is pushed into the shaft portion 70, the inserted lock piece 76 is The guide action by the guide portion 71 at the tip of the shaft portion 70 is also helped to be slightly expanded outward, and the pushing operation is allowed. However, once the pushing operation is stopped, the tip of the elastic lock piece 75 is engaged with the surface of the shaft portion 70 to slightly bite at that position. Thereafter, even if the pressing plates 52 and 52 are pressed in the direction of removing from the shaft portion 70, the pressed force acts in a direction to further bite the lock piece 76 into the shaft portion 70. Will not come off.
In this way, if the elastic lock piece 75 is made of metal and the shaft portion 70 side is made of resin, the presser plates 52 and 53 can be attached to the shaft portion 70 at any position by the metal biting into the surface of the resin. It becomes possible to lock it.
