　特許文献１に記載の鞍乗型車両は、物品収納ボックスとシートの各端部にヒンジ片が設けられ、各ヒンジ片が金属製のヒンジピン（枢軸）によって連結されている。 In the saddle-ride type vehicle described in Patent Document 1, hinge pieces are provided at each end of an article storage box and a seat, and the hinge pieces are connected by metal hinge pins (pivots).
　また、鞍乗型車両のシート下の構造として、物品収納ボックスに回動可能に中蓋が設けられ、シートを跳ね上げた状態において、中蓋を物品収納ボックスのボックス開口に対して開閉できるようにしたものが知られている（例えば、特許文献２参照）。 In addition, as a structure under the seat of the saddle-ride type vehicle, an inner lid is provided rotatably in the article storage box, and the inner lid can be opened and closed with respect to the box opening of the article storage box in a state where the seat is flipped up. Those known in the art are known (see, for example, Patent Document 2).
　特許文献２に記載の鞍乗型車両は、物品収納ボックスに樹脂製の枢軸が一体に設けられ、中蓋の端部に枢軸に回動可能に係合される樹脂製の係合片が設けられている。係合片には、周方向の一部が開口した抱持部が設けられ、その抱持時に、枢軸が軸方向と略直交する方向から挿入されるようになっている。抱持部の開口は、中蓋が開き方向に所定角度以上開いた姿勢のときにのみ枢軸を受容できるように形成されており、中蓋の開き方向の回動は回動規制部材（例えば、シート）によって規制されている。
　したがって、この鞍乗型車両の場合、回動規制部材を取り外した状態では、中蓋を自由に脱着することができるが、回動規制部材が取り付けられた状態では、中蓋の脱着が規制される。 In the saddle-ride type vehicle described in Patent Document 2, a resin-made pivot is integrally provided in an article storage box, and a resin-made engagement piece rotatably engaged with the pivot is provided at the end of the inner lid. It is done. The engaging piece is provided with a holding portion in which a part in the circumferential direction is opened, and at the time of holding, the pivot is inserted from a direction substantially orthogonal to the axial direction. The opening of the holding portion is formed so as to be able to receive the pivot only when the inner lid is in the opening direction and opened in a predetermined angle or more, and rotation of the inner lid in the opening direction is a rotation restricting member (for example, Seats are regulated.
Therefore, in the case of this saddle-ride type vehicle, the inner lid can be freely attached and detached in the state in which the rotation regulating member is removed, but in the state in which the rotation regulating member is attached, the detachment of the inner lid is restricted. Ru.

(1) A saddle-ride type vehicle according to one aspect of the present invention is rotatably attached to an article storage box (4) having a box opening (10a) opening upward, and the article storage box (4). In a saddle-ride type vehicle provided with a seat (3) for occupant seating capable of opening and closing the box opening (10a), one of the article storage box (4) and the seat (3) is made of resin Of the article storage box (4) and the sheet (3), the resin holding portion (30) holding the pivot (19) in a relatively rotatable manner. And an insertion opening (30a) through which the pivot (19) can be inserted and removed in a direction perpendicular to the axis is provided in a part of the circumferential direction of the holding portion (30), and the article storage box (4) In the seat (3), the pivot (19) is inserted and opened. The article storage box (4) and the sheet (3) in the direction in which the pivot (19) is disengaged from the insertion opening (30a) when inserted into the inside of the holding portion (30) through (30a) A resin box side locking portion (22) and a sheet side locking portion (23) for regulating relative displacement are respectively provided, and the box side locking portion (22) and the sheet side locking portion (23) are provided. Is at least one of the box side locking part (22) and the sheet side locking part (23) by receiving a pressing load when the pivot (19) is inserted into the holding part (30). And a guide abutment surface (22a, 23a) which allows the insertion of the pivot (19) into the holding portion (30) by elastically deforming the support portion (30), and the pivot (19) is inserted into the holding portion (30) In mutual contact with each other from the holding portion (30) Omission regulating surface for regulating the escape of the serial pivot (19) and (22b, 23b), are provided.
　上記態様（１）により、物品収納ボックス（４）にシート（３）を取り付ける場合には、抱持部（３０）の挿入開口（３０ａ）に枢軸（１９）が軸直交方向で向き合うにようにシート（３）の姿勢を調整し、枢軸（１９）が挿入開口（３０ａ）を通して抱持部（３０）に挿入されるように、シート（３）と物品収納ボックス（４）を相対変位させる。こうして、シート（３）と物品収納ボックス（４）を相対変位させると、シート側係止部（２３）のガイド当接面（２３ａ）とボックス側係止部（２２）のガイド当接面（２２ａ）が当接して、ボックス側係止部（２２）とシート側係止部（２３）の少なくとも一方が弾性変形する。このとき、抱持部（３０）への枢軸（１９）の挿入が許容される。枢軸（１９）が抱持部（３０）に挿入されると、シート側係止部（２３）の抜け規制面（２３ｂ）とボックス側係止部（２２）の抜け規制面（２２ｂ）が相互に当接し、それによって抱持部（３０）からの枢軸（１９）の抜けが規制される。この結果、抱持部（３０）に枢軸（１９）が回動可能に保持され、シート（３）が物品収納ボックス（４）に回動可能に連結されることになる。
　また、物品収納ボックス（４）からシート（３）を取り外す場合には、シート（３）を所定の開き位置に回動させた状態で、シート（３）を捩る等してシート側係止部（２３）とボックス側係止部（２２）との係合を外す。これにより、枢軸（１９）が挿入開口（３０ａ）を通して抱持部（３０）から抜ける。この結果、シート（３）が物品収納ボックス（４）から取り外される。 According to the above aspect (1), when the sheet (3) is attached to the article storage box (4), the pivot shaft (19) faces the insertion opening (30a) of the holding portion (30) in the axial orthogonal direction. The attitude of the sheet (3) is adjusted, and the sheet (3) and the article storage box (4) are relatively displaced so that the pivot (19) is inserted into the holding portion (30) through the insertion opening (30a). Thus, when the sheet (3) and the article storage box (4) are displaced relative to each other, the guide contact surface (23a) of the seat side locking portion (23) and the guide contact surface of the box side locking portion (22) 22a) abuts, and at least one of the box-side locking portion (22) and the seat-side locking portion (23) is elastically deformed. At this time, the insertion of the pivot (19) into the holding portion (30) is permitted. When the pivot (19) is inserted into the holding portion (30), the removal restricting surface (23b) of the seat side locking portion (23) and the removal restricting surface (22b) of the box side locking portion (22) mutually Abut on the peg, thereby restricting the removal of the pivot (19) from the holding part (30). As a result, the pivot (19) is rotatably held by the holding portion (30), and the sheet (3) is rotatably connected to the article storage box (4).
Further, when removing the sheet (3) from the article storage box (4), the sheet (3) is twisted or the like while the sheet (3) is rotated to the predetermined opening position, and the sheet side locking portion Release the engagement between (23) and the box side locking part (22). Thereby, the pivot (19) comes out of the holding part (30) through the insertion opening (30a). As a result, the sheet (3) is removed from the article storage box (4).
（２）上記態様（１）において、前記ボックス側係止部（２２）と前記シート側係止部（２３）の対は、前記枢軸（１９）の軸方向に離間して二組設けられ、各組の対応する一方の前記ガイド当接面（２３ａ）は、前記抱持部（３０）に対する前記枢軸（１９）の挿抜方向に対して相反方向に傾斜するようにしても良い。 (2) In the above aspect (1), two pairs of the box-side locking portion (22) and the sheet-side locking portion (23) are provided separately in the axial direction of the pivot (19), The corresponding one of the guide contact surfaces (23a) of each set may be inclined in the opposite direction with respect to the insertion / removal direction of the pivot (19) with respect to the holding portion (30).
　上記態様（２）の場合、枢軸（１９）を抱持部（３０）に挿入するときに、二つのシート側係止部（２３）のガイド当接面（２３ａ）を対応する二つのボックス側係止部（２２）のガイド当接面（２２ａ）に当接させて変位させると、各他方のガイド当接面（２２ａ）が相反方向に傾斜する各一方のガイド当接面（２３ａ）に案内されることになる。この結果、シート（３）が枢軸（１９）の軸方向で位置決めされて物品収納ボックス（４）に組み付けられる。したがって、この構成を採用した場合には、シート（３）を物品収納ボックス（４）に容易に組み付けることができる。 In the case of the above mode (2), when the pivot (19) is inserted into the holding portion (30), the guide contact surfaces (23a) of the two seat side locking portions (23) correspond to the two corresponding box sides When the guide abutment surface (22a) of the locking portion (22) is abutted and displaced, each other guide abutment surface (22a) is inclined in the opposite direction to each one guide abutment surface (23a) It will be guided. As a result, the sheet (3) is positioned in the axial direction of the pivot (19) and assembled to the article storage box (4). Therefore, when this configuration is adopted, the sheet (3) can be easily assembled to the article storage box (4).
（３）上記態様（１）または（２）において、前記枢軸（１９）は、前記物品収納ボックス（４）の樹脂成形部と一体に形成され、前記抱持部（３０）は、前記シート（３）の樹脂成形部と一体に形成されており、前記抱持部（３０）の前記挿入開口（３０ａ）は、前記シート（３）が前記物品収納ボックス（４）に対して開き方向に所定角度傾斜した組付け姿勢のときに、水平方向よりも下方側に向くように形成されるようにしても良い。 (3) In the above aspect (1) or (2), the pivot (19) is integrally formed with the resin molded portion of the article storage box (4), and the holding portion (30) is the sheet ( The insertion opening (30a) of the holding portion (30) is formed integrally with the resin molded portion of 3), in the opening direction of the sheet (3) relative to the article storage box (4). It may be formed to face downward with respect to the horizontal direction when in the assembly posture in which the angle inclination is made.
　上記態様（３）の場合、シート（３）を物品収納ボックス（４）に対して開き方向に所定角度傾斜した組付け姿勢にし、その状態でシート（３）を下方に変位させることにより、シート（３）側の抱持部（３０）の挿入開口（３０ａ）に物品収納ボックス（４）側の枢軸（１９）を挿入することができる。したがって、この構成を採用した場合には、シート（３）を重力方向にほぼ沿うように変位させて物品収納ボックス（４）に組み付けることができるため、シート（３）の組付け作業が容易になる。 In the case of the above aspect (3), the sheet (3) is assembled in an assembly posture inclined at a predetermined angle in the opening direction with respect to the article storage box (4), and the sheet (3) is displaced downward in that state. (3) The pivot (19) on the article storage box (4) side can be inserted into the insertion opening (30a) of the side holding portion (30). Therefore, when this configuration is adopted, the sheet (3) can be displaced along the direction of gravity and assembled to the article storage box (4), so the sheet (3) can be easily assembled. Become.
（４）上記態様（１）～（３）のいずれか１つにおいて、前記物品収納ボックス（４）の側の抜け規制面（２２ｂ）と前記シート（３）の側の抜け規制面（２３ｂ）は、前記シート（３）が前記物品収納ボックス（４）に組み付けられた状態において、前記シート（３）の開き方向の回動を規制する回動ストッパを構成するようにしても良い。 (4) In any one of the above aspects (1) to (3), the drop regulating surface (22b) on the side of the article storage box (4) and the drop regulating surface (23b) on the side of the sheet (3) In the state where the sheet (3) is assembled to the article storage box (4), a rotation stopper may be configured to restrict rotation of the sheet (3) in the opening direction.
　上記態様（４）の場合、物品収納ボックス（４）の側の抜け規制面（２２ｂ）とシート（３）の側の抜け規制面（２３ｂ）がシート（３）の開き方向の回動を規制する回動ストッパとしても機能するため、シート（３）の回動ストッパを別途設ける必要がなくなる。したがって、この構成を採用した場合には、物品収納ボックス（４）やシート（３）の構造を簡素化し、物品収納ボックス（４）やシート（３）の製造をより容易化することができる。 In the case of the above aspect (4), the removal regulating surface (22b) on the side of the article storage box (4) and the removal regulating surface (23b) on the side of the sheet (3) regulate rotation of the sheet (3) in the opening direction. Since the sheet also functions as a rotation stopper, it is not necessary to separately provide a rotation stopper for the sheet (3). Therefore, when this configuration is adopted, the structures of the article storage box (4) and the sheet (3) can be simplified, and the manufacture of the article storage box (4) and the sheet (3) can be further facilitated.
　本発明に係る態様によれば、枢軸や抱持部、ボックス側係止部、シート側係止部等のシート取付部の主要な部品が樹脂によって形成されるため、部品点数の増加を抑制しつつ、シートを物品収納ボックスに回動可能に取り付けることができる。
　また、本発明に係る態様によれば、枢軸を抱持部に挿入してシートを物品収納ボックスに回動可能に組み付けるときには、シート側係止部とボックス側係止部のガイド当接面同士を当接させることにより、シート側係止部とボックス側係止部の少なくともいずれか一方を弾性変形させて抱持部への枢軸の挿入を許容し、その後にシート側係止部とボックス側係止部の抜け規制面同士が相互に当接することにより、保持部の挿入開口からの枢軸の抜けを規制することができる。また、シートを物品収納ボックスから取り外すときには、シートを所定の開き姿勢にした状態で、シート側係止部とボックス側係止部の少なくともいずれか一方を弾性変形させることにより、枢軸を抱持部から抜くことができる。したがって、本発明に係る態様によれば、シートの脱着作業を容易に行うことができる。 According to the aspect of the present invention, the main parts of the seat attachment portion such as the pivot, the holding portion, the box side locking portion, and the seat side locking portion are formed of resin, so that the increase in the number of parts is suppressed.

The left and right box side locking portions 22 are engageable with the corresponding sheet side locking portions 23 of the seat side hinge block 16. The box side locking portion 22 will be described in detail later.
　シート側ヒンジブロック１６は、シートベース１３の裏面の前部側領域から裏面と交差する方向（シート３が閉じられた状態で物品収納ボックス４に向かう方向）に延びる抱持部３０とシート側係止部２３とを備えている。抱持部３０とシート側係止部２３は、車幅方向左右に離間して各一対設けられている。シート側係止部２３は、左右の各抱持部３０の車幅方向外側位置に突設されている。 The seat-side hinge block 16 extends from the front side area of the back surface of the seat base 13 to a direction crossing the back surface (a direction toward the article storage box 4 with the sheet 3 closed) and the seat-side engagement A stop 23 is provided. The holding portion 30 and the seat-side locking portion 23 are provided in pairs, being separated in the lateral direction of the vehicle. The seat-side locking portion 23 is provided at a position outside the vehicle width direction of each of the left and right holding portions 30.
　抱持部３０は、ボックス側ヒンジブロック１２の枢軸１９を回動可能に受容する部分であり、内側に枢軸１９を回動可能に支持し得る円弧状の抱持面（符号省略）を有している。また、抱持部３０は、周方向の一部に挿入開口３０ａが形成されている。挿入開口３０ａは、物品収納ボックス４にシート３を組み付けるときに、枢軸１９を軸直交方向から抱持部３０の内側に挿入し、物品収納ボックス４からシート３を取り外すときに、枢軸１９を抱持部３０の内側から抜き外す部分である。 The holding portion 30 is a portion rotatably receiving the pivot 19 of the box side hinge block 12 and has an arc-shaped holding surface (reference numeral omitted) capable of rotatably supporting the pivot 19 inside. ing. Moreover, the holding part 30 is formed with the insertion opening 30a in a part of circumferential direction. The insertion opening 30 a inserts the pivot 19 into the inside of the holding portion 30 from the direction orthogonal to the axis when assembling the sheet 3 to the article storage box 4, and holds the pivot 19 when removing the sheet 3 from the article storage box 4. It is a portion pulled out from the inside of the holding portion 30.
　本実施形態の場合、挿入開口３０ａは、図７に示すように、シート３を物品収納ボックス４に対して最大に開いた組付け姿勢のとき（以下、シート３のこの姿勢を単に「組付け姿勢」と呼ぶ。）に、ほぼ下方に向かって開口するように形成されている。なお、シート３が組付け姿勢のときの挿入開口３０ａの向きは、真下に向いている必要がないが、水平方向よりも下方側に向くように形成されることが望ましい。 In the case of the present embodiment, as shown in FIG. 7, when the insertion opening 30a is in the assembly posture in which the sheet 3 is maximally opened with respect to the article storage box 4 (hereinafter, this posture of the sheet 3 is simply It is formed so as to open substantially downward. The direction of the insertion opening 30a when the seat 3 is in the assembled posture does not have to be directly below, but it is preferable that the direction of the insertion opening 30a be formed to be downward with respect to the horizontal direction.
　ここで、ボックス側係止部２２とシート側係止部２３は、シート３が組付け姿勢の状態で、枢軸１９が挿入開口３０ａを通して左右の抱持部３０に挿入されたときに相互に係合し、それによって挿入開口３０ａから枢軸１９が抜ける方向の物品収納ボックス４とシート３の相対変位を規制する。 Here, the box side locking portion 22 and the seat side locking portion 23 are engaged with each other when the pivot shaft 19 is inserted into the left and right holding portions 30 through the insertion opening 30a in the state where the seat 3 is in the assembled posture. And thereby restrict the relative displacement of the article storage box 4 and the sheet 3 in the direction in which the pivot 19 is removed from the insertion opening 30a.
　図５，図６，図８に示すように、ボックス側係止部２２は、側部延出壁１７の平坦な上面から車幅方向外側に向かって斜め下方に傾斜するボックス側ガイド当接面２２ａ（ガイド当接面）と、そのボックス側ガイド当接面２２ａの下端から鉛直下方に延びる側壁の下端から車幅方向内側に略水平に延びるボックス側抜け規制面２２ｂ（抜け規制面）と、を有している。 As shown in FIGS. 5, 6 and 8, the box-side locking portion 22 is a box-side guide contact surface that inclines obliquely downward from the flat upper surface of the side extension wall 17 toward the outer side in the vehicle width direction. 22a (guide contact surface), and box side slippage restriction surface 22b (dropout restriction surface) extending substantially horizontally inward in the vehicle width direction from the lower end of the side wall extending vertically downward from the lower end of the box side guide contact surface 22a; have.
　ボックス側ガイド当接面２２ａは、枢軸１９が挿入開口３０ａを通して抱持部３０の内側に挿入されるときに、シート側係止部２３の後述するシート側ガイド当接面２３ａ（ガイド当接面）に当接する。このとき、ボックス側ガイド当接面２２ａは、シート３に加わる作業者による押圧荷重を受けることで、シート側ガイド当接面２３ａと摺接しつつシート側係止部２３を車幅方向外側に弾性変形させる。また、シート側係止部２３は、枢軸１９が挿入開口３０ａを通して抱持部３０の内側に挿入された時点で形状が復帰し、ボックス側抜け規制面２２ｂがシート側係止部２３の後述するシート側抜け規制面２３ｂに当接する。これにより、抱持部３０からの枢軸１９の抜けが規制される。 The box-side guide contact surface 22a is a seat-side guide contact surface 23a (guide contact surface described later of the sheet-side locking portion 23) when the pivot 19 is inserted inside the holding portion 30 through the insertion opening 30a. Abuts). At this time, the box-side guide contact surface 22a receives the pressing load by the operator applied to the seat 3, and thereby the seat-side locking portion 23 is resilient outward in the vehicle width direction while slidingly contacting with the seat-side guide contact surface 23a. Transform it. The seat side locking portion 23 returns in shape when the pivot 19 is inserted into the inside of the holding portion 30 through the insertion opening 30a, and the box side removal restricting surface 22b will be described later of the sheet side locking portion 23. It abuts on the seat-side slippage restricting surface 23b. Thus, the removal of the pivot 19 from the holding unit 30 is restricted.
　シート側係止部２３は、図８に示すように、シート側抜け規制面２３ｂを有する短辺と、シート側ガイド当接面２３ａを有する長辺を備えた断面略Ｌ字状の板状のブロックによって構成されている。シート側係止部２３の略Ｌ字状の断面は、シートベース１３の裏面から略直交方向（シート３が閉じられた状態で物品収納ボックス４に向かう方向）に所定長さ延出している。シート側係止部２３は、シート３が組付け姿勢のとき、図８に示すように、短辺が車幅方向外側に略水平に延び、かつ、長辺が短辺との連接部から車幅方向外側に傾斜しつつ下方に延びる断面形状とされている。シート側抜け規制面２３ｂは、このとき短辺の上面となる部分によって形成されており、シート側ガイド当接面２３ａは、このとき長辺の車幅方向内側に向く面によって形成されている。左右のシート側係止部２３のシート側ガイド当接面２３ａは、図８に示すように、シート３が組付け姿勢のときに、抱持部３０に対する枢軸１９の挿抜方向（上下方向）に対して、相反方向に同角度傾斜している。具体的には、左右のシート側ガイド当接面２３ａは、下方に向かって互いの離間幅が次第に増大するように相反方向に同角度傾斜している。 As shown in FIG. 8, the sheet-side locking portion 23 is a plate having a substantially L-shaped cross section including a short side having a sheet-side slippage restricting surface 23 b and a long side having a sheet-side guide contact surface 23 a. It is composed of blocks. The substantially L-shaped cross section of the seat-side locking portion 23 extends from the back surface of the seat base 13 in a substantially orthogonal direction (direction toward the article storage box 4 with the seat 3 closed). When the seat 3 is in the assembly orientation, as shown in FIG. 8, the seat-side locking portion 23 has a short side extending substantially horizontally outward in the vehicle width direction and a long side extending from the connecting portion with the short side. It is made into the cross-sectional shape extended downward, inclining to the width direction outer side. The seat-side slippage restricting surface 23b is formed by a portion that is the upper surface of the short side at this time, and the seat-side guide contact surface 23a is formed by a surface facing inward in the vehicle width direction of the long side at this time. The seat side guide contact surfaces 23a of the left and right seat side locking portions 23 are, as shown in FIG. 8, in the insertion / removal direction (vertical direction) of the pivot 19 with respect to the holding portion 30 when the seat 3 is in the assembly posture In contrast, they are inclined at the same angle in the opposite direction. Specifically, the left and right sheet-side guide contact surfaces 23a are inclined at the same angle in the opposite direction so that the separation width gradually increases downward.
　左右のボックス側係止部２２の前端部は、シート３が物品収納ボックス４に組み付けられた状態では、図９Ａ，図９Ｂに示すように、枢軸１９の軸心ｏ１とほぼ重なるように形成されている。左右のシート側抜け規制面２３ｂは、シート３が、図９Ａに示す組付け姿勢のときに、枢軸１９の軸心ｏ１よりも後方側領域のみでボックス側抜け規制面２２ｂに当接するようになっている。したがって、この状態からシート３に閉じ方向の回動操作力が加わった場合には、図９Ｂに示すように、シート側係止部２３がボックス側係止部２２と干渉せずに自由に回動することができる。そして、シート側係止部２３は、シート側抜け規制面２３ｂがボックス側係止部２２のボックス側抜け規制面２２ｂと当接することにより、シート３の所定角度以上の回動を規制する。本実施形態の場合、ボックス側抜け規制面２２ｂとシート側抜け規制面２３ｂは、シート３が物品収納ボックス４に組み付けられた状態においては、シート３の開き方向の回動ストッパとしても機能する。 The front end portions of the left and right box side locking portions 22 are formed so as to substantially overlap with the axial center o1 of the pivot 19 as shown in FIGS. 9A and 9B in a state where the sheet 3 is assembled to the article storage box 4. ing. When the seat 3 is in the assembly posture shown in FIG. 9A, the left and right seat side slip restriction surfaces 23b come into contact with the box side slip restriction surface 22b only in the rear side region with respect to the axial center o1 of the pivot 19 ing. Therefore, when a rotational operation force in the closing direction is applied to the sheet 3 from this state, as shown in FIG. 9B, the sheet side locking portion 23 does not interfere with the box side locking portion 22 and is freely rotated. Can move. The seat-side locking portion 23 regulates the rotation of the sheet 3 by a predetermined angle or more by the sheet-side slippage regulating surface 23b coming into contact with the box-side slippage regulating surface 22b of the box-side hooking portion 22. In the case of the present embodiment, the box-side slip restriction surface 22 b and the sheet-side slip restriction surface 23 b also function as a rotation stopper in the opening direction of the sheet 3 in a state where the sheet 3 is assembled to the article storage box 4.
　以上の構成において、実際にシート３を物品収納ボックス４に組み付ける場合には、抱持部３０の挿入開口３０ａがほぼ下方を向くようにシート３を組付姿勢にし、挿入開口３０ａをボックス側ヒンジブロック１２の枢軸１９の上方側で枢軸１９と向かい合わせる。
　このとき、左右のシート側係止部２３は、図８中の仮想線で示すように、ボックス側ヒンジブロック１２の左右の対応するボックス側係止部２２の上方に位置される。 In the above configuration, when the sheet 3 is actually assembled to the article storage box 4, the sheet 3 is assembled so that the insertion opening 30a of the holding portion 30 faces substantially downward, and the insertion opening 30a is hinged on the box side. It faces the pivot 19 on the upper side of the pivot 19 of the block 12.
At this time, the left and right seat-side locking portions 23 are positioned above the corresponding left and right box-side locking portions 22 of the box-side hinge block 12, as shown by the phantom lines in FIG.
　次に、この状態から枢軸１９が挿入開口３０ａを通して左右の抱持部３０に挿入されるように、物品収納ボックス４に対してシート３を下方に変位させる。こうして、シート３を下方に変位させると、左右のシート側ガイド当接面２３ａが対応するボックス側ガイド当接面２２ａに当接し、ボックス側ガイド当接面２２ａに摺接しつつ車幅方向外側に弾性変型する。このとき、左右のシート側係止部２３のシート側ガイド当接面２３ａは、抱持部３０に対する枢軸１９の挿抜方向（上下方向）に対して相反方向に傾斜しているため、シート３の下方変位の進行とともにシート３が車幅方向の規定の位置に自然に位置決めされる。 Next, the sheet 3 is displaced downward with respect to the article storage box 4 so that the pivot 19 is inserted into the left and right holding parts 30 through the insertion opening 30a from this state. Thus, when the seat 3 is displaced downward, the left and right seat-side guide contact surfaces 23a contact the corresponding box-side guide contact surfaces 22a and make sliding contact with the box-side guide contact surfaces 22a outward in the vehicle width direction. Elastic deformation. At this time, the sheet-side guide contact surfaces 23 a of the left and right seat-side locking portions 23 are inclined in opposite directions with respect to the insertion and removal direction (vertical direction) of the pivot 19 with respect to the holding portion 30. As the downward displacement progresses, the seat 3 is naturally positioned at a prescribed position in the vehicle width direction.
　この状態でシート３がさらに下方に変位すると、左右のシート側係止部２３が左右の対応するボックス側係止部２２を乗り越えて自身の弾性によって形状復帰し、左右のシート側抜け規制面２３ｂが対応するボックス側抜け規制面２２ｂに当接するようになる（図８，図９Ａ参照）。この結果、挿入開口３０ａを通した抱持部３０からの枢軸１９の抜けが規制され、枢軸１９が抱持部３０内に回動可能に保持されるようになる。シート３は、その後に枢軸１９を中心として閉じ方向に回動操作され、物品収納ボックス４の上部に重ねられた状態で車体フレームＦ側の係止部に固定される。 When the sheet 3 is further displaced downward in this state, the left and right seat side locking portions 23 get over the corresponding left and right box side locking portions 22 and return in shape due to their own elasticity, and the left and right sheet side slippage restricting surfaces 23b Comes into contact with the corresponding box side removal restricting surface 22b (see FIGS. 8 and 9A). As a result, the removal of the pivot 19 from the holding portion 30 through the insertion opening 30 a is restricted, and the pivot 19 is rotatably held in the holding portion 30. Thereafter, the seat 3 is pivoted in the closing direction about the pivot 19 and fixed to the locking portion on the vehicle body frame F side in a state of being superimposed on the upper part of the article storage box 4.
　また、物品収納ボックス４からシート３を取り外す場合には、シート３を所定の開き位置に回動させた状態（シート３を組付姿勢にした状態）で、作業者がシート３を左右に捩る等して、左右のシート側係止部２３とボックス側係止部２２との係合を外す。これにより、抱持部３０に対する枢軸１９の抜け規制が解除され、枢軸１９からの抱持部３０の引き抜きが可能になる。この状態でシート３を上方に持ち上げることにより、シート３が物品収納ボックス４から取り外される。 Further, when removing the sheet 3 from the article storage box 4, the operator twists the sheet 3 to the left and right in a state in which the sheet 3 is rotated to a predetermined opening position (a state in which the sheet 3 is in the assembling posture). Similarly, the engagement between the left and right seat side locking portions 23 and the box side locking portion 22 is released. Thereby, the removal restriction of the pivot 19 with respect to the holding unit 30 is released, and the holding unit 30 can be pulled out from the pivot 19. The sheet 3 is removed from the article storage box 4 by lifting the sheet 3 upward in this state.
　以上のように、本実施形態に係る自動二輪車１は、シート取付部の枢軸１９や抱持部３０、ボックス側係止部２２、シート側係止部２３等の主要な部品が樹脂によって形成されるため、部品点数の増加を抑制しつつ、シート３を物品収納ボックス４に回動可能に取り付けることができる。特に、本実施形態のようにシート取付部の上記の主要な部品を、ボックス本体部１０やシートベース１３と樹脂によって一体に形成するようにした場合には、部品点数のさらなる削減と製造の容易化を図ることができる。 As described above, in the motorcycle 1 according to the present embodiment, main parts such as the pivot 19 of the seat mounting portion, the holding portion 30, the box side locking portion 22 and the seat side locking portion 23 are formed of resin. Therefore, the sheet 3 can be rotatably attached to the article storage box 4 while suppressing an increase in the number of parts. In particular, when the above main components of the sheet mounting portion are integrally formed with the box main body 10 and the sheet base 13 by resin as in the present embodiment, the number of parts can be further reduced and the manufacture can be facilitated. Can be implemented.
　また、本実施形態に係る自動二輪車１においては、枢軸１９を挿入開口３０ａを通して抱持部３０に挿入してシート３を物品収納ボックス４に組み付けるときに、シート側ガイド当接面２３ａをボックス側ガイド当接面２２ａに摺接させつつ、シート３を挿入方向に押圧することにより、シート側係止部２３を車幅方向外側に弾性変型させて抱持部３０への枢軸１９の挿入を許容し、シート側係止部２３がボックス側係止部２２を乗り越えて形状復帰することによってシート側抜け規制面２３ｂをボックス側抜け規制面２２ｂに当接させることができる。したがって、本実施形態の構成を採用した場合には、物品収納ボックス４に対するシート３の取付作業を容易に行うことができる。 Further, in the motorcycle 1 according to the present embodiment, when the pivot 19 is inserted into the gripping portion 30 through the insertion opening 30a and the seat 3 is assembled to the article storage box 4, the seat side guide contact surface 23a is on the box side. By pressing the seat 3 in the insertion direction while making sliding contact with the guide contact surface 22a, the seat side locking portion 23 is elastically deformed outward in the vehicle width direction, and insertion of the pivot 19 into the holding portion 30 is permitted. When the seat-side locking portion 23 passes over the box-side locking portion 22 and returns in shape, the sheet-side slippage restricting surface 23b can be brought into contact with the box-side slippage restriction surface 22b. Therefore, when the configuration of the present embodiment is adopted, the work of attaching the sheet 3 to the article storage box 4 can be easily performed.
　さらに、本実施形態に係る自動二輪車１においては、シート３を物品収納ボックス４から取り外すときに、シート３を所定の開き姿勢にした状態でシート側係止部２３を弾性変形させることにより、枢軸１９から抱持部３０を容易に抜くことができる。したがって、本実施形態の構成を採用した場合には、物品収納ボックス４からのシート３の取り外し作業も容易に行うことができる。 Furthermore, in the motorcycle 1 according to the present embodiment, when the seat 3 is removed from the article storage box 4, the pivot is achieved by elastically deforming the seat side locking portion 23 in a state in which the seat 3 is in the predetermined opening posture. The holding unit 30 can be easily pulled out from 19. Therefore, when the configuration of the present embodiment is adopted, the work of removing the sheet 3 from the article storage box 4 can be easily performed.
　また、本実施形態に係る自動二輪車１は、ボックス側係止部２２とシート側係止部２３の対が枢軸１９の軸方向に離間して二組設けられ、左右の各組のシート側ガイド当接面２３ａが抱持部３０に対する枢軸１９の挿抜方向（上下方向）に対して相反方向に傾斜している。このため、シート３側の抱持部３０に物品収納ボックス４の枢軸１９を挿入するときに、相反方向に傾斜した左右のシート側ガイド当接面２３ａを対応するボックス側ガイド当接面２２ａに当接させることにより、シート３を車幅方向の所定位置に自然に位置決めすることができる。したがって、この構成を採用した場合には、物品収納ボックス４に対するシート３の組付け作業がより容易になる。 Further, in the motorcycle 1 according to the present embodiment, two pairs of the box-side locking portion 22 and the seat-side locking portion 23 are provided apart from each other in the axial direction of the pivot shaft 19 The contact surface 23 a is inclined in the opposite direction with respect to the insertion / removal direction (vertical direction) of the pivot 19 with respect to the holding portion 30. For this reason, when inserting the pivot 19 of the article storage box 4 into the holding portion 30 on the sheet 3 side, the left and right sheet side guide contact surfaces 23a inclined in the opposite direction to the corresponding box side guide contact surfaces 22a. By bringing the seat 3 into contact, the seat 3 can be naturally positioned at a predetermined position in the vehicle width direction. Therefore, when this configuration is adopted, the work of assembling the sheet 3 to the article storage box 4 becomes easier.
　また、本実施形態に係る自動二輪車１は、枢軸１９が物品収納ボックス４のボックス本体部１０と一体に樹脂形成され、抱持部３０がシート３のシートベース１３と一体に樹脂成形されており、抱持部３０の挿入開口３０ａが、シート３が組付姿勢のときに、水平方向よりも下方に向くように形成されている。このため、この構成を採用した場合には、シート３を重力方向にほぼ沿うように変位させて物品収納ボックス４に組み付けることができることから、物品収納ボックス４に対するシート３の組付けをより容易にすることができる。 Further, in the motorcycle 1 according to the present embodiment, the pivot 19 is made of resin integrally with the box body 10 of the article storage box 4, and the holding portion 30 is made of resin integrally with the seat base 13 of the seat 3. The insertion opening 30a of the holding portion 30 is formed to face downward as compared to the horizontal direction when the sheet 3 is in the assembly posture. For this reason, when this configuration is adopted, the sheet 3 can be attached to the article storage box 4 by displacing the sheet 3 substantially along the direction of gravity, so the assembly of the sheet 3 to the article storage box 4 is made easier. can do.
　さらに、本実施形態に係る自動二輪車１では、ボックス側抜け規制面２２ｂとシート側抜け規制面２３ｂが、シート３の開き方向の回動を規制する回動ストッパの機能を兼ねるように構成されている。したがって、この構成を採用した場合には、シート３の開き方向の回動を規制する回動ストッパを別途設ける必要がなくなるため、物品収納ボックス４やシート３の構造を簡素化して、物品収納ボックス４やシート３の製造をより容易化することができる。 Furthermore, in the motorcycle 1 according to the present embodiment, the box-side slip restricting surface 22b and the seat-side slip restricting surface 23b are configured to double as the function of a rotation stopper that restricts the rotation of the seat 3 in the opening direction. There is. Therefore, when this configuration is adopted, there is no need to separately provide a rotation stopper for restricting the rotation of the sheet 3 in the opening direction, so the structures of the article storage box 4 and the sheet 3 are simplified The manufacture of the sheet 4 and the sheet 3 can be further facilitated.
