　しかしながら特許文献１では、ハンドル部とセンタパイプとの接合部にパッチを当てて補強している。そのため、部品点数が多くなることがあった。又、ハンドル部とセンタパイプとの溶接工程と、パッチとハンドル部及びセンタパイプとの溶接工程とを別工程に分ける必要があり、作業工数が多くなることがあった。 However, in Patent Document 1, the joint portion between the handle portion and the center pipe is reinforced by applying a patch. For this reason, the number of parts may increase. Further, it is necessary to divide the welding process between the handle portion and the center pipe and the welding process between the patch, the handle portion and the center pipe into separate processes, which increases the number of work steps.
　本発明の態様は、鞍乗り型車両のハンドル構造及び鞍乗り型車両のハンドル構造の製造方法において、部品点数を削減しつつ、作業工数を削減することを目的とする。 An object of the present invention is to reduce the number of work steps while reducing the number of parts in a saddle-ride type vehicle handle structure and a saddle-ride type vehicle handle structure manufacturing method.
　上記課題の解決手段として、本発明は以下の態様を採用した。
　（１）本発明の一態様に係る鞍乗り型車両のハンドル構造は、バーハンドルと、前記バーハンドルを固定するハンドルポストとを備え、前記バーハンドルが固定される側の前記ハンドルポストの端部には、前記バーハンドルの軸線に沿うように分岐して前記バーハンドルに嵌合する分岐部が形成され、前記分岐部は、前記ハンドルポストと同一の部材により一体に形成される。 As a means for solving the above problems, the present invention employs the following aspects.
(1) A handle structure of a saddle-ride type vehicle according to one aspect of the present invention includes a bar handle and a handle post that fixes the bar handle, and an end portion of the handle post on a side to which the bar handle is fixed Is formed with a branch portion that branches along the axis of the bar handle and fits into the bar handle, and the branch portion is integrally formed with the same member as the handle post.
　（２）上記（１）の態様において、前記分岐部と前記バーハンドルとの嵌合部には、前記バーハンドルと前記ハンドルポストとが溶接される第一溶接部が形成される。 (2) In the aspect of the above (1), a first welded portion where the bar handle and the handle post are welded is formed at a fitting portion between the branch portion and the bar handle.
　（３）上記（１）又は（２）の態様において、前記分岐部は、前記軸線に沿うように前記ハンドルポストの端部を二股に分岐した一対の分岐部を備える。 (3) In the above aspect (1) or (2), the branch portion includes a pair of branch portions in which the end portion of the handle post is bifurcated along the axis.
　（４）上記（１）～（３）のいずれか一項の態様において、前記分岐部と前記バーハンドルとの嵌合部には、カバーを支持するカバーステイが固定され、前記カバーステイには、前記嵌合部に重なる重なり部が形成され、前記重なり部には、前記カバーステイと前記嵌合部とが溶接される第二溶接部が形成される。 (4) In the aspect described in any one of (1) to (3) above, a cover stay that supports a cover is fixed to a fitting portion between the branch portion and the bar handle, and the cover stay An overlapping portion that overlaps the fitting portion is formed, and a second welded portion where the cover stay and the fitting portion are welded is formed in the overlapping portion.
　（５）上記（４）の態様において、前記バーハンドルと前記ハンドルポストとが溶接される第一溶接部は、前記重なり部の前記第二溶接部と連続するように前記重なり部とは重ならない位置の前記嵌合部に形成される。 (5) In the aspect of the above (4), the first welded portion where the bar handle and the handle post are welded does not overlap the overlapped portion so as to be continuous with the second welded portion of the overlapped portion. It is formed in the fitting part at a position.
　（６）上記（１）～（５）のいずれか一項の態様において、前記分岐部は、筒状の前記ハンドルポストの長手方向に沿うように前記端部にスリットを形成し、前記バーハンドルの前記分岐部への嵌合形状に沿うように前記スリットを有する前記端部を押し拡げることにより形成される。 (6) In the aspect according to any one of (1) to (5), the branch portion has a slit formed at the end portion along the longitudinal direction of the cylindrical handle post, and the bar handle Is formed by expanding the end portion having the slit so as to conform to the fitting shape to the branch portion.
　上記（１）の態様によれば、バーハンドルが固定される側のハンドルポストの端部に、バーハンドルの軸線に沿うように分岐してバーハンドルに嵌合する分岐部を形成し、分岐部をハンドルポストと同一の部材により一体に形成することで、補強部材としてのパッチを必要とせずにバーハンドルを固定できる。そのため、パッチを設ける構成と比較して、パッチ分の部品を減らすことができる。従って、部品点数を削減しつつ、作業工数を削減することができる。又、バーハンドルの軸線に沿うように分岐して分岐部を形成するため、バーハンドルの径方向に沿うように分岐して分岐部を形成する場合と比較して、分岐部とバーハンドルとの嵌合部を大きく確保することができ、バーハンドルを強固に支持することができる。 According to the aspect of the above (1), the branch portion that branches along the axis of the bar handle and fits to the bar handle is formed at the end of the handle post on the side to which the bar handle is fixed, Is integrally formed of the same member as the handle post, so that the bar handle can be fixed without requiring a patch as a reinforcing member. Therefore, the parts for the patch can be reduced as compared with the configuration in which the patch is provided. Therefore, it is possible to reduce the number of work steps while reducing the number of parts. Also, since the branch portion is formed by branching along the axis of the bar handle, the branch portion and the bar handle are compared with the case where the branch portion is formed by branching along the radial direction of the bar handle. A large fitting portion can be secured and the bar handle can be firmly supported.
　上記（２）の態様によれば、分岐部とバーハンドルとの嵌合部に、バーハンドルとハンドルポストとが溶接される溶接部を形成することで、補強部材としてのパッチを必要とせずにバーハンドルを溶接できる。そのため、パッチを設ける構成と比較して、パッチ分の溶接工程を別工程で設ける必要がなくなる。そのため、溶接工程を削減することができ、作業工数を削減することができる。 According to the above aspect (2), the welded portion where the bar handle and the handle post are welded is formed at the fitting portion between the branch portion and the bar handle, so that a patch as a reinforcing member is not required. Bar handle can be welded. Therefore, it is not necessary to provide a welding process for the patch in a separate process as compared with the configuration in which the patch is provided. Therefore, a welding process can be reduced and work man-hours can be reduced.
　上記（３）の態様によれば、分岐部が、軸線に沿うようにハンドルポストの端部を二股に分岐した一対の分岐部を備えることで、ハンドルポストにより直接バーハンドルを幅広く支持することができる。 According to the aspect of (3), the bar handle can be widely supported directly by the handle post by providing the pair of branch portions in which the end portion of the handle post is bifurcated along the axis. it can.
　上記（４）の態様によれば、カバーステイに、嵌合部に重なる重なり部を形成し、重なり部に、カバーステイと嵌合部とが溶接される溶接部を形成することで、ハンドル構造にカバーステイが設けられる場合においても、補強部材としてのパッチを必要とせずにバーハンドルを固定できる。そのため、部品点数を削減しつつ、作業工数を削減することができる。 According to the aspect of (4) above, the handle structure is formed by forming the overlapping portion overlapping the fitting portion on the cover stay, and forming the welded portion where the cover stay and the fitting portion are welded to the overlapping portion. Even when a cover stay is provided, the bar handle can be fixed without the need for a patch as a reinforcing member. Therefore, it is possible to reduce the number of work steps while reducing the number of parts.
　上記（５）の態様によれば、バーハンドルとハンドルポストとが溶接される溶接部を、重なり部の溶接部と連続するように重なり部とは重ならない位置の嵌合部に形成することで、嵌合部における溶接工程と重なり部における溶接工程とを連続して同一工程で行うことができる。そのため、嵌合部における溶接工程と重なり部における溶接工程とを別工程で行う場合と比較して、作業工数を削減することができる。 According to the above aspect (5), the welded portion where the bar handle and the handle post are welded is formed in the fitting portion at a position that does not overlap the overlapped portion so as to be continuous with the welded portion of the overlapped portion. The welding process in the fitting part and the welding process in the overlapping part can be continuously performed in the same process. Therefore, compared with the case where the welding process in a fitting part and the welding process in an overlap part are performed by another process, an operation man-hour can be reduced.
　上記（６）の態様によれば、筒状のハンドルポストの長手方向に沿うように端部にスリットを形成し、バーハンドルの分岐部への嵌合形状に沿うようにスリットを有する端部を押し拡げることにより分岐部を形成することで、バーハンドルの分岐部への嵌合形状に沿うように分岐部のバーハンドルへの嵌合形状を形成することができる。そのため、ハンドルポストをバーハンドルの形状に正確に沿わせることができる。従って、バーハンドルとハンドルポストとの組み付け精度を向上することができ、バーハンドルを高精度で且つ強固に支持することができる。 According to the above aspect (6), the slit is formed at the end portion along the longitudinal direction of the cylindrical handle post, and the end portion having the slit is formed along the fitting shape to the branch portion of the bar handle. By forming the branch portion by expanding, it is possible to form the fitting shape of the branch portion to the bar handle along the fitting shape of the bar handle to the branch portion. For this reason, the handle post can be accurately aligned with the shape of the bar handle. Therefore, the assembly accuracy of the bar handle and the handle post can be improved, and the bar handle can be supported with high accuracy and strength.

　先ず、分岐部形成工程Ｓ１では、バーハンドル２０が固定される側のハンドルポスト３０の端部３２ｅを軸線Ｃ１に沿うように分岐してバーハンドル２０に嵌合する分岐部３２を形成する。具体的には図８に示すように、ハンドルポスト３０を形成するハンドルポスト形成部材６０を用意する。例えば、ハンドルポスト形成部材６０は、円筒状の鋼管により形成される。ハンドルポスト形成部材６０の端部６２ｅは、上方に山形に突出するように形成される。ハンドルポスト形成部材６０には、軸線Ｃ１０と直交する方向にハンドルポスト形成部材６０の下部６１を貫通する円形の前貫通孔３１ｈが形成される。尚、ハンドルポスト形成部材６０の下部６１は、ハンドルポスト３０の本体部３１を形成する本体部形成部に相当する。 First, in the branch portion forming step S1, the end portion 32e of the handle post 30 on the side to which the bar handle 20 is fixed is branched along the axis C1 to form the branch portion 32 that fits the bar handle 20. Specifically, a handle post forming member 60 for forming the handle post 30 is prepared as shown in FIG. For example, the handle post forming member 60 is formed of a cylindrical steel pipe. An end 62e of the handle post forming member 60 is formed so as to protrude upward in a mountain shape. The handle post forming member 60 is formed with a circular front through hole 31h that passes through the lower portion 61 of the handle post forming member 60 in a direction orthogonal to the axis C10. The lower portion 61 of the handle post forming member 60 corresponds to a main body portion forming portion that forms the main body portion 31 of the handle post 30.
　次に、図９に示すように、ハンドルポスト形成部材６０の長手方向に沿うように端部６２ｅにスリット３２ｓを形成する（スリット形成工程）。尚、図中符号Ｃ１０は、ハンドルポスト形成部材６０の中心軸を通る軸線を示す。軸線Ｃ１０は、本体部３１の中心軸を通る軸線Ｃ２（図２参照）に相当する。 Next, as shown in FIG. 9, a slit 32s is formed in the end 62e along the longitudinal direction of the handle post forming member 60 (slit forming step). In the figure, reference numeral C10 indicates an axis passing through the central axis of the handle post forming member 60. The axis C10 corresponds to an axis C2 (see FIG. 2) passing through the central axis of the main body 31.
　スリット形成工程では、先ず、ハンドルポスト形成部材６０の端部６２ｅの上方に、カッター７０を配置する。カッター７０は、軸線Ｃ１０と直交する方向に延びる軸線Ｃ１１を有する回転軸７１と、回転軸７１に取り付けられる回転刃７２とを備える。回転軸７１の一端部にはモーター等の駆動部（不図示）が接続される。例えば、回転刃７２は、駆動部による回転軸７１の回転に伴って図９に示す矢印の方向Ｖ１（軸線Ｃ１１回り）に回転する。 In the slit forming step, first, the cutter 70 is disposed above the end 62e of the handle post forming member 60. The cutter 70 includes a rotating shaft 71 having an axis C11 extending in a direction orthogonal to the axis C10, and a rotating blade 72 attached to the rotating shaft 71. A driving unit (not shown) such as a motor is connected to one end of the rotating shaft 71. For example, the rotary blade 72 rotates in the arrow direction V1 (around the axis C11) shown in FIG. 9 with the rotation of the rotary shaft 71 by the drive unit.
　スリット形成工程では、ハンドルポスト形成部材６０の端部６２ｅの上方にカッター７０を配置した後、前記端部６２ｅからカッター７０の回転刃７２を下方に入れ込み、ハンドルポスト形成部材６０の上部６２にスリット３２ｓを形成する。尚、ハンドルポスト形成部材６０の上部６２は、ハンドルポスト３０の分岐部３２を形成する分岐部形成部に相当する。尚、カッター７０によりスリット３２ｓを形成することに限らず、例えばプレス加工によりスリット３２ｓを形成してもよい。 In the slit forming step, after the cutter 70 is disposed above the end portion 62e of the handle post forming member 60, the rotary blade 72 of the cutter 70 is inserted downward from the end portion 62e, and the slit is formed in the upper portion 62 of the handle post forming member 60. 32s is formed. The upper portion 62 of the handle post forming member 60 corresponds to a branching portion forming portion that forms the branching portion 32 of the handle post 30. Note that the slit 32s is not limited to being formed by the cutter 70, and the slit 32s may be formed by, for example, pressing.
　次に、図１０に示すように、スリット形成工程の後、プレス型８０でスリット３２ｓを有する端部６２ｅを押し拡げることにより分岐部３２を形成する（プレス工程）。プレス型８０は、スリット３２ｓが形成されたハンドルポスト形成部材６０を収容する収容部８１ｓを有する第一の型８１と、スリット３２ｓを有する端部６２ｅを挟んで第一の型８１と対向して配置される第二の型８３とを備える。第二の型８３には、上述したバーハンドル２０（図３参照）の分岐部３２への嵌合形状を有し、且つ、下方にＵ字状に突出する凸部８４が形成される。第二の型８３には、前記凸部８４に嵌合可能に下方にＵ字状に凹む凹部８２が形成される。 Next, as shown in FIG. 10, after the slit forming step, the branch portion 32 is formed by expanding the end portion 62 e having the slit 32 s with the press die 80 (pressing step). The press die 80 is opposed to the first die 81 with a first die 81 having an accommodating portion 81s for accommodating the handle post forming member 60 in which the slit 32s is formed, and an end 62e having the slit 32s. And a second mold 83 to be arranged. The second mold 83 is formed with a convex portion 84 having a fitting shape to the branch portion 32 of the above-described bar handle 20 (see FIG. 3) and protruding downward in a U shape. The second mold 83 is formed with a concave portion 82 that is recessed downward in a U shape so as to be able to fit into the convex portion 84.
　プレス工程では、先ず、スリット３２ｓが形成されたハンドルポスト形成部材６０を第一の型８１の収容部８１ｓに収容する。その後、スリット３２ｓを有する端部６２ｅを挟んで第一の型８１と対向するように第二の型８３を配置し、第一の型８１に収容されたハンドルポスト形成部材６０に対して図１０に示す矢印の方向Ｖ２にプレスする。 In the pressing step, first, the handle post forming member 60 in which the slit 32s is formed is accommodated in the accommodating portion 81s of the first die 81. Thereafter, the second die 83 is disposed so as to face the first die 81 with the end 62e having the slit 32s interposed therebetween, and the handle post forming member 60 accommodated in the first die 81 is shown in FIG. Is pressed in the direction of the arrow V2.
　これにより、ハンドルポスト形成部６０の端部６２ｅを二股に分岐し、図１１に示すように一対の分岐部３２Ｌ，３２Ｒを形成する。その後、ハンドルポスト形成部６０の上下中間部を所定角度だけ折り曲げることにより、図２に示すハンドルポスト３０を形成する。 Thereby, the end portion 62e of the handle post forming portion 60 is bifurcated to form a pair of branch portions 32L and 32R as shown in FIG. Thereafter, the handle post 30 shown in FIG. 2 is formed by bending the upper and lower intermediate portions of the handle post forming portion 60 by a predetermined angle.
　プレス工程の後の嵌合工程Ｓ２では、バーハンドル２０に一対の分岐部３２Ｌ，３２Ｒを嵌合させる。本実施形態では、プレス工程において、バーハンドル２０の分岐部３２への嵌合形状を有するプレス型８０でスリット３２ｓを有する端部６２ｅを押し拡げることにより分岐部３２を形成する。そのため、バーハンドル２０の分岐部３２への嵌合形状に沿うように分岐部３２のバーハンドル２０への嵌合形状を形成することができる。したがって、嵌合工程Ｓ２では、バーハンドル２０に一対の分岐部３２Ｌ，３２Ｒを正確に嵌合することができる。 In the fitting step S2 after the pressing step, the pair of branch portions 32L and 32R are fitted to the bar handle 20. In the present embodiment, in the pressing process, the branch portion 32 is formed by expanding the end portion 62e having the slit 32s with a press die 80 having a fitting shape to the branch portion 32 of the bar handle 20. Therefore, the fitting shape to the bar handle 20 of the branch part 32 can be formed so that the fitting shape to the branch part 32 of the bar handle 20 may be followed. Therefore, in the fitting step S2, the pair of branch portions 32L and 32R can be accurately fitted to the bar handle 20.
　嵌合工程Ｓ２の後の溶接工程Ｓ３では、図６に示すように、一対の分岐部３２Ｌ，３２Ｒにバーハンドル２０を嵌合させた状態で、一対の分岐部３２Ｌ，３２Ｒとバーハンドル２０との嵌合部２５を溶接することによりバーハンドル２０をハンドルポスト３０に固定する。具体的に溶接工程Ｓ３では、図６に示すように、左右嵌合部２５Ｌ，２５Ｒにおいて、左右分岐部３２Ｌ，３２Ｒの上端縁３２ｕとバーハンドル２０の中間部２２とを溶接することによりバーハンドル２０をハンドルポスト３０に固定する。 In the welding step S3 after the fitting step S2, as shown in FIG. 6, with the bar handle 20 fitted to the pair of branch portions 32L, 32R, the pair of branch portions 32L, 32R and the bar handle 20 The bar handle 20 is fixed to the handle post 30 by welding the fitting portion 25. Specifically, in the welding step S3, as shown in FIG. 6, the bar handle is obtained by welding the upper edge 32u of the left and right branch parts 32L and 32R and the intermediate part 22 of the bar handle 20 in the left and right fitting parts 25L and 25R. 20 is fixed to the handle post 30.
　上述したようにハンドルポスト形成部材６０の端部６２ｅは上方に山形に突出するように形成される。そのため、ハンドルポスト形成部材６０の端部６２ｅが軸線Ｃ１０に直交する直線状に形成される場合と比較して、溶接工程Ｓ３において、左右分岐部３２Ｌ，３２Ｒの上端縁３２ｕとバーハンドル２０の中間部２２との溶接代を長くすることができ、バーハンドル２０をハンドルポスト３０に強固に固定することができる。 As described above, the end 62e of the handle post forming member 60 is formed so as to protrude upward in a mountain shape. Therefore, compared with the case where the end portion 62e of the handle post forming member 60 is formed in a straight line perpendicular to the axis C10, the intermediate between the upper end edge 32u of the left and right branch portions 32L and 32R and the bar handle 20 in the welding step S3. The welding allowance with the portion 22 can be increased, and the bar handle 20 can be firmly fixed to the handle post 30.
　溶接工程Ｓ３では、図３、図４に示すように、分岐部３２にバーハンドル２０を嵌合させた状態で、中央嵌合部２５Ｃに前後カバーステイ４０，５０の連結部４３，５３を重ね合わせ、中央嵌合部２５Ｃと前後カバーステイ４０，５０の連結部４３，５３との重なり部４５，５５を溶接する。
　以上の工程により、本実施形態に係るハンドル構造体２（図２参照）が製造される。 In the welding step S3, as shown in FIGS. 3 and 4, the connecting portions 43 and 53 of the front and rear cover stays 40 and 50 are overlapped on the center fitting portion 25C in a state where the bar handle 20 is fitted to the branch portion 32. In addition, the overlapping portions 45 and 55 of the center fitting portion 25C and the connecting portions 43 and 53 of the front and rear cover stays 40 and 50 are welded.
The handle structure 2 (see FIG. 2) according to this embodiment is manufactured through the above steps.
　以上説明したように、本実施形態の鞍乗り型車両のハンドル構造は、バーハンドル２０と、バーハンドル２０を固定するハンドルポスト３０とを備え、バーハンドル２０が固定される側のハンドルポスト３０の端部３２ｅには、バーハンドル２０の軸線Ｃ１に沿うように分岐してバーハンドル２０に嵌合する分岐部３２が形成され、分岐部３２は、ハンドルポスト３０と同一の部材により一体に形成される。
　この構成によれば、バーハンドル２０が固定される側のハンドルポスト３０の端部３２ｅに、バーハンドル２０の軸線Ｃ１に沿うように分岐してバーハンドル２０に嵌合する分岐部３２を形成し、分岐部３２をハンドルポスト３０と同一の部材により一体に形成することで、補強部材としてのパッチを必要とせずにバーハンドル２０を固定できる。そのため、パッチを設ける構成と比較して、パッチ分の部品を減らすことができる。従って、部品点数を削減しつつ、作業工数を削減することができる。又、バーハンドル２０の軸線Ｃ１に沿うように分岐して分岐部３２を形成するため、バーハンドル２０の径方向に沿うように分岐して分岐部を形成する場合と比較して、分岐部３２とバーハンドル２０との嵌合部２５を大きく確保することができ、バーハンドル２０を強固に支持することができる。 As described above, the handle structure of the saddle-ride type vehicle according to the present embodiment includes the bar handle 20 and the handle post 30 that fixes the bar handle 20, and the handle post 30 on the side to which the bar handle 20 is fixed. The end portion 32e is formed with a branch portion 32 that branches along the axis C1 of the bar handle 20 and fits with the bar handle 20, and the branch portion 32 is integrally formed by the same member as the handle post 30. The
According to this configuration, a branch portion 32 that branches along the axis C1 of the bar handle 20 and fits to the bar handle 20 is formed at the end portion 32e of the handle post 30 on the side to which the bar handle 20 is fixed. By forming the branch portion 32 integrally with the same member as the handle post 30, the bar handle 20 can be fixed without requiring a patch as a reinforcing member. Therefore, the parts for the patch can be reduced as compared with the configuration in which the patch is provided. Therefore, it is possible to reduce the number of work steps while reducing the number of parts. Further, since the branch portion 32 is formed by branching along the axis C1 of the bar handle 20, the branch portion 32 is compared with the case where the branch portion is formed by branching along the radial direction of the bar handle 20. And a large fitting portion 25 between the bar handle 20 and the bar handle 20 can be firmly supported.
　又、分岐部３２とバーハンドル２０との嵌合部２５に、バーハンドル２０とハンドルポスト３０とが溶接される溶接部３２ｕを形成することで、補強部材としてのパッチを必要とせずにバーハンドル２０を溶接できる。そのため、パッチを設ける構成と比較して、パッチ分の溶接工程を別工程で設ける必要がなくなる。そのため、溶接工程を削減することができ、作業工数を削減することができる。 Further, by forming a welded portion 32u where the bar handle 20 and the handle post 30 are welded to the fitting portion 25 between the branch portion 32 and the bar handle 20, the bar handle is not required as a reinforcing member. 20 can be welded. Therefore, it is not necessary to provide a welding process for the patch in a separate process as compared with the configuration in which the patch is provided. Therefore, a welding process can be reduced and work man-hours can be reduced.
　又、分岐部３２が、軸線Ｃ１に沿うようにハンドルポスト３０の端部３２ｅを二股に分岐した一対の分岐部３２Ｌ，３２Ｒを備えることで、ハンドルポスト３０により直接バーハンドル２０を幅広く支持することができる。 Further, since the branch portion 32 includes a pair of branch portions 32L and 32R in which the end portion 32e of the handle post 30 is bifurcated along the axis C1, the bar handle 20 can be directly supported by the handle post 30 widely. Can do.
　又、前後カバーステイ４０，５０に、嵌合部２５に重なる重なり部４５，５５を形成し、重なり部４５，５５に、前後カバーステイ４０，５０と嵌合部２５とが溶接される溶接部４３ｕ，４３ｌ，４３ｒ，５３ｕ，５３ｌ，５３ｒを形成することで、ハンドル構造に前後カバーステイ４０，５０が設けられる場合においても、補強部材としてのパッチを必要とせずにバーハンドル２０を固定できる。そのため、部品点数を削減しつつ、作業工数を削減することができる。 The front and rear cover stays 40 and 50 are formed with overlapping portions 45 and 55 that overlap the fitting portion 25, and the overlapping portions 45 and 55 are welded portions where the front and rear cover stays 40 and 50 and the fitting portion 25 are welded. By forming 43u, 43l, 43r, 53u, 53l, 53r, the bar handle 20 can be fixed without requiring a patch as a reinforcing member even when the front and rear cover stays 40, 50 are provided in the handle structure. Therefore, it is possible to reduce the number of work steps while reducing the number of parts.
　又、バーハンドル２０とハンドルポスト３０とが溶接される溶接部３２ｕを、重なり部４５，５５の溶接部４３ｕ，４３ｌ，４３ｒ，５３ｕ，５３ｌ，５３ｒと連続するように重なり部４５，５５とは重ならない位置の嵌合部２５に形成することで、嵌合部２５における溶接工程と重なり部４５，５５における溶接工程とを連続して同一工程で行うことができる。そのため、嵌合部２５における溶接工程と重なり部４５，５５における溶接工程とを別工程で行う場合と比較して、作業工数を削減することができる。 Further, the welded portion 32u where the bar handle 20 and the handle post 30 are welded is connected to the welded portions 43u, 43l, 43r, 53u, 53l, and 53r of the overlapped portions 45 and 55 with the overlapped portions 45 and 55. By forming in the fitting part 25 of the position which does not overlap, the welding process in the fitting part 25 and the welding process in the overlapping parts 45 and 55 can be performed continuously in the same process. Therefore, compared with the case where the welding process in the fitting part 25 and the welding process in the overlap parts 45 and 55 are performed by another process, an operation man-hour can be reduced.
　又、筒状のハンドルポスト３０の長手方向に沿うように端部３２ｅにスリット３２ｓを形成し、バーハンドル２０の分岐部３２への嵌合形状に沿うようにスリット３２ｓを有する端部３２ｅを押し拡げることにより分岐部３２を形成することで、バーハンドル２０の分岐部３２への嵌合形状に沿うように分岐部３２のバーハンドル２０への嵌合形状を形成することができる。そのため、ハンドルポスト３０をバーハンドル２０の形状に正確に沿わせることができる。従って、バーハンドル２０とハンドルポスト３０との組み付け精度を向上することができ、バーハンドル２０を高精度で且つ強固に支持することができる。 Further, a slit 32s is formed in the end portion 32e along the longitudinal direction of the cylindrical handle post 30, and the end portion 32e having the slit 32s is pushed along the fitting shape of the bar handle 20 to the branch portion 32. By forming the branch portion 32 by spreading, the fitting shape of the branch portion 32 to the bar handle 20 can be formed so as to follow the fitting shape of the bar handle 20 to the branch portion 32. Therefore, the handle post 30 can be accurately aligned with the shape of the bar handle 20. Therefore, the assembly accuracy of the bar handle 20 and the handle post 30 can be improved, and the bar handle 20 can be supported with high accuracy and strength.

For example, the front and rear cover stays 40 and 50 may not be provided in the handle structure. Further, only one of the front and rear cover stays 40 and 50 may be provided in the handle structure.
　又、上記実施形態では、カバーとしてハンドルカバー５を支持するカバーステイ４０，５０を備える例を挙げて説明したが、これに限らない。例えば、カバーとして車体カバー６を支持するカバーステイを備えてもよい。 In the above embodiment, the cover stays 40 and 50 that support the handle cover 5 are described as examples of the cover. However, the present invention is not limited to this. For example, a cover stay that supports the vehicle body cover 6 may be provided as a cover.
　尚、本発明は上記実施形態に限られるものではない。例えば、前記鞍乗型車両には、運転者が車体を跨いで乗車する車両全般が含まれ、自動二輪車（原動機付自転車及びスクータ型車両を含む）のみならず、三輪（前一輪且つ後二輪の他に、前二輪且つ後一輪の車両も含む）又は四輪の車両も含まれる。
　そして、上記実施形態における構成は本発明の一例であり、実施形態の構成要素を周知の構成要素に置き換える等、本発明の要旨を逸脱しない範囲で種々の変更が可能である。 The present invention is not limited to the above embodiment. For example, the straddle-type vehicle includes all vehicles on which the driver rides across the vehicle body, and includes not only motorcycles (including motorbikes and scooter type vehicles) but also three-wheelers (front one wheel and rear two wheels). Other examples include a front two-wheel and a rear one vehicle) or a four-wheel vehicle.
