図6は、スプラッシュガードの前方部品3と後方部品4とを接続手段である前記板状突起35A、35Bを、貫通孔45A、45Bに貫通・挿入させ一体化を図った(スプラッシュガードGとして組立てられた)状態が示されている。   In FIG. 6, the plate-like protrusions 35A and 35B as connecting means for connecting the front part 3 and the rear part 4 of the splash guard are penetrated and inserted into the through holes 45A and 45B (assembled as the splash guard G). Status).

スプラッシュガードの前後部品3,4の一体化(組付け)工程について、さらに図11〜図14を参照して詳細に説明する。   The process of integrating (assembling) the front and rear parts 3 and 4 of the splash guard will be further described in detail with reference to FIGS.

先ず、図11及び図13において、後方部品4の側面、すなわち、側板部41の接合端部41eの車両外方から前記後方部品4の当該管通孔45A、45Bに向って前記前方部品3の板状突起35A、35Bを貫通させる。   First, in FIG. 11 and FIG. 13, the side of the rear part 4, that is, the outer side of the joint end 41 e of the side plate part 41, toward the pipe through holes 45 </ b> A and 45 </ b> B of the rear part 4, The plate-like protrusions 35A and 35B are penetrated.

貫通後に、後方部品4の車両中心方向から外方に向かい(図13の矢印Y1方向)、U字状のクリップPを板状突起35Aの先端から被せる(図14の状態)。
このクリップPは、U字の内部に例えば、強力な接着剤が塗布してあり、板状突起35Aからの離脱を自ら防いでいる。
このクリップPの板状突起35Aへの装着は、装着時の厚みtが貫通孔45Aのスリット幅よりも大きいため前後部品3,4の離脱を防止する。
After the penetration, the rear part 4 is directed outward from the vehicle center direction (in the direction of arrow Y1 in FIG. 13), and a U-shaped clip P is placed over the tip of the plate-like protrusion 35A (state shown in FIG. 14).
For example, a strong adhesive is applied to the inside of the U-shape of the clip P to prevent the clip P from being detached from the plate-like protrusion 35A.
When the clip P is attached to the plate-like protrusion 35A, the thickness t at the time of attachment is larger than the slit width of the through hole 45A, thereby preventing the front and rear parts 3 and 4 from being detached.

図12は、スプラッシュガードの前後部品3,4がスプラッシュガードGに一体化された状態が示されている。   FIG. 12 shows a state in which the front and rear parts 3 and 4 of the splash guard are integrated with the splash guard G.

図15及び、図16は、上述のように一体化されたフェンダ本体F及びスプラッシュガードGを、図示しない前記フェンダ本体(の前後部品)の第2の接続部材16,26の貫通孔26c、16c(図2,3参照)にスプラッシュガードG(の前後部品3,4)のフランジ33,43に形成された取付孔33c、43cを位置合わせし(フランジ33,43に形成された取付孔33c、43cは、第2の接続部材16,26の雌ねじを有する貫通孔16c、26cの内の下方フランジ側の全てと、同時に一致するように配置されている)、締結部材、例えば図示しないビスによってショートフェンダSFとスプラッシュガードGが一体化された状態を示している。   15 and FIG. 16, the fender body F and the splash guard G integrated as described above are connected to the through holes 26c and 16c of the second connection members 16 and 26 of the fender body (front and rear parts) (not shown). (See FIGS. 2 and 3), the mounting holes 33c and 43c formed in the flanges 33 and 43 of the splash guard G (the front and rear parts 3 and 4 thereof) are aligned (the mounting holes 33c formed in the flanges 33 and 43, 43c is arranged to coincide with all of the lower flange side of the through holes 16c and 26c having the female threads of the second connecting members 16 and 26 at the same time), and is short-circuited by a fastening member, for example, a screw (not shown) A state in which the fender SF and the splash guard G are integrated is shown.

即ち、図14,15では最終目的である集合体のショートフェンダSFが完成している。   That is, in FIGS. 14 and 15, the short fender SF of the aggregate which is the final purpose is completed.

上述したような構成及び製造方法のショートフェンダSFは、フェンダ本体Fの前方部品1は標準フェンダG1と、ショートフェンダSFで共通化でき、複数種類の型を予め用意しておく必要がないので、製造コストの削減に繋がるとともに、型の管理のための労力、コストが不要である。 In the short fender SF of the configuration and manufacturing method as described above, the front part 1 of the fender body F can be shared by the standard fender G1 and the short fender SF, and it is not necessary to prepare a plurality of types of molds in advance. This leads to a reduction in manufacturing costs and does not require labor and cost for mold management.

フェンダ本体FとスプラッシュガードGとを別体に製造しており、スプラッシュガードにGおいてもフェンダ本体F同様に標準品とショートフェンダ用とで、共通化出来、同様の効果が得られる。   The fender main body F and the splash guard G are manufactured separately, and even in the splash guard G, the standard product and the short fender can be used in the same manner as the fender main body F, and the same effect can be obtained.

フェンダ本体F及びスプラッシュガードGとも、前方部品1,3と後方部品2,4に嵌合式の接合部材(第1の接合部材)15,35;25,45を形成してあるため、位置決めが容易で、作業性は向上する。 Both the fender body F and the splash guard G are easy to position because the front parts 1 and 3 and the rear parts 2 and 4 are formed with fitting-type joining members (first joining members) 15, 35; 25, 45. Thus, workability is improved.

ショートキャブ専用の型を使うよりも型の大きさが小さく出来、型費用が削減出来る。   The size of the mold can be made smaller and the cost of the mold can be reduced compared to using a dedicated mold for the short cab.

切断の際にはレーザ切断が用いることが出来、その様にレーザ切断を用いた場合は、精度は極めてよい。   When cutting, laser cutting can be used, and when laser cutting is used as such, the accuracy is very good.
