また、キャビン２０の側方において、把手３０ａを有した透明な乗降ドア３０が開閉自在に設けられていると共に、その後方には２段階調整式のリアウィンドウ３４が開閉自在に設けられている。乗降ドア３０は、ヒンジ３１，３１によって中部フレーム２２に取付けられ、リアウィンドウ３４はヒンジ３３，３３によって後部フレーム２３に取付けられている。   Further, on the side of the cabin 20, a transparent entrance door 30 having a handle 30 a is provided so as to be openable and closable, and a two-stage adjustable rear window 34 is provided in the rear thereof so as to be openable and closable. The passenger door 30 is attached to the middle frame 22 by hinges 31, 31, and the rear window 34 is attached to the rear frame 23 by hinges 33, 33.

更に、左右一対の後部フレーム２３，２３の間には、上部フレーム２４に設けられたヒンジ４３，４３によって後部ウィンドウ４２が上部に大きく開くように構成されると共に、該上部フレーム２４にルーフ３９が取付けられることによってキャビン２０は外部から密閉して構成されている。なお、後部ウィンドウ４２が上部に大きく開くため、オペレータは三点リンク機構４４に取付けられる作業機を容易に調整可能である。   Further, between the pair of left and right rear frames 23, 23, a rear window 42 is configured to be opened upward by hinges 43, 43 provided on the upper frame 24, and a roof 39 is provided on the upper frame 24. By being attached, the cabin 20 is configured to be sealed from the outside. In addition, since the rear window 42 opens to the upper part, the operator can easily adjust the work machine attached to the three-point link mechanism 44.

次に本願発明の要部である灯火装置１，３６について説明をする。   Next, the lighting devices 1 and 36 which are the main part of this invention are demonstrated.

リアリアウィンドウ３４の下方かつ後輪１３の上方にはリアフェンダ３５が設けられており、該リアフェンダ３５には後方用灯火装置３６が設けられている。図９に示すように後方用灯火装置３６は、機体外側に後方方向指示器４０、機体内側にブレーキ灯４１が設けられている。   A rear fender 35 is provided below the rear rear window 34 and above the rear wheel 13, and a rear lighting device 36 is provided on the rear fender 35. As shown in FIG. 9, the rear lighting device 36 is provided with a rear direction indicator 40 on the outer side of the body and a brake light 41 on the inner side of the body.

また、キャビン２０の前部フレーム２１には、サイドミラー４５，４５及び前部灯火装置１，１が左右一対ずつ取付けられており、図１（ａ），（ｂ）に示すように該前部灯火装置１は、前方方向指示器２、側方方向指示器３、車幅灯４、ステップランプ５、遮光板（遮光部材）６及びこれらを一体に取付けているブラケット８から構成されている。   In addition, side mirrors 45 and 45 and a pair of front lighting devices 1 and 1 are attached to the front frame 21 of the cabin 20 one by one, as shown in FIGS. 1 (a) and 1 (b). The lighting device 1 includes a front direction indicator 2, a side direction indicator 3, a vehicle width lamp 4, a step lamp 5, a light shielding plate (light shielding member) 6, and a bracket 8 on which these are integrally attached.

図２（ａ），（ｂ）に示すようにブラケット８は、ボルト７によって前部フレーム２１に固定されており、機体の上下方向に長い略々長方形をしている。該ブラケット８の機体前方からみた正面部には、前方方向指示器２及び車幅灯４が配設され、底部には、乗降ドア３０の下方のステップ３２及びその周囲を照らすステップランプ５が取付けられている。   As shown in FIGS. 2 (a) and 2 (b), the bracket 8 is fixed to the front frame 21 by bolts 7 and has a substantially rectangular shape that is long in the vertical direction of the fuselage. A front direction indicator 2 and a vehicle width lamp 4 are arranged on the front portion of the bracket 8 as viewed from the front of the machine body, and a step 32 below the entrance door 30 and a step lamp 5 that illuminates the surrounding area are attached to the bottom. It has been.

更に、ブラケット８の側面部のうち、機体外側には側方方向指示器３が配設されており、機体内側の運転手側の側面には遮光板６がブラケット８のカバー８ａより延設されている。オペレータは、該遮光板６により、前方方向指示器２及び車幅灯４の照射光によって眩惑することはない。   Further, of the side portions of the bracket 8, the side direction indicator 3 is disposed outside the fuselage, and the light shielding plate 6 extends from the cover 8 a of the bracket 8 on the driver side surface inside the fuselage. ing. An operator is not dazzled by the light emitted from the front direction indicator 2 and the vehicle width lamp 4 by the light shielding plate 6.

図３に示すように前方方向指示器２と車幅灯４とは一体に装着されており、機体上下方向に長い略々長方形の形状をしている。この一体に装着された前方方向指示器２及び車幅灯４は、該前方方向指示器２が上方に、車幅灯４が下方に配設されると共に、前方方向指示器２は車幅灯４よりも長く構成されている。なお、遮光板６の高さ（機体上下方向）及び幅（機体前後方向）は前方方向指示器２と車幅灯４とが一体に装着された状態の高さ及び幅よりも大きく形成される。   As shown in FIG. 3, the front direction indicator 2 and the vehicle width lamp 4 are integrally mounted and have a substantially rectangular shape that is long in the vertical direction of the fuselage. The front direction indicator 2 and the vehicle width lamp 4 that are integrally mounted are arranged such that the front direction indicator 2 is disposed above and the vehicle width light 4 is disposed below, and the front direction indicator 2 is disposed on the vehicle width light. It is longer than 4. In addition, the height (width direction of the machine body) and the width (back and forth direction of the machine body) of the light shielding plate 6 are formed larger than the height and width when the front direction indicator 2 and the vehicle width lamp 4 are integrally mounted. .

一方、図４に示すように側方方向指示器３は、楕円形状に形成され、差込部３ａをブラケット８のソケットに差込んで取付けられており、前方方向指示器２とは別々のフラッシャランプによって点滅している。また、図５に示すようにステップランプ５は半球形状に形成され、差込部５ａをブラケット８のソケットに差込んで取付けられている。該ステップランプ５は、ブラケット８のカバー８ａによって周囲を囲まれており、機体後方下側に向って傾斜してステップ３２及びその周辺の路面のみ照らすように構成されている。   On the other hand, as shown in FIG. 4, the side direction indicator 3 is formed in an elliptical shape, and is attached by inserting the insertion portion 3 a into the socket of the bracket 8, and is a flasher separate from the front direction indicator 2. It is flashing by the lamp. Further, as shown in FIG. 5, the step lamp 5 is formed in a hemispherical shape, and is attached by inserting the insertion portion 5 a into the socket of the bracket 8. The step lamp 5 is surrounded by a cover 8a of the bracket 8 and is inclined so as to illuminate only the step 32 and the surrounding road surface by inclining toward the rear lower side of the fuselage.

なお、前方灯火装置１は、前部フレーム２１の中途部のうち、サイドミラー４５の下方、かつ乗降ドア３０の把手３０aの斜め上方の高さに装着されているが、より下方である把手３０aと同位置の高さ等に装着しても良い。   The front lighting device 1 is mounted at a height below the side mirror 45 and obliquely above the handle 30a of the entry / exit door 30 in the middle part of the front frame 21, but the handle 30a at a lower position. It may be mounted at the same position as the height.

次に本発明に係る灯火装置１，３６の作用について説明する。   Next, the operation of the lighting devices 1 and 36 according to the present invention will be described.

オペレータは、圃場までの移動に際して、トラクタ１０によって路上を走行する。オペレータは右左折もしくは車線変更等をする際、方向指示器スイッチを左右のどちらか曲がりたい方向に操作し、前方方向指示器２、側方方向指示器３及び後方方向指示器４０の左右一方を点滅させる。上記方向指示器２，３，３６の照射光は、周囲のどの車輌からでも視認することができ、安全に右左折等ができる。   The operator travels on the road by the tractor 10 when moving to the field. When the operator turns right or left or changes lanes, the operator operates the direction indicator switch in either the left or right direction, and turns the left or right of the front direction indicator 2, the side direction indicator 3 and the rear direction indicator 40. Blink. Irradiation light from the direction indicators 2, 3, and 36 can be viewed from any surrounding vehicle, and can be safely turned right and left.

また、夜間走行時には車幅灯４を点灯させると共に、乗降ドア３０の開閉の際にはステップランプ５がステップ３２及び足元の路面を照らすため、オペレータは安全にトラクタ１０の操縦部に乗降することができる。更に、遮光板６によって前部灯火装置１によって眩惑することもない。   In addition, the vehicle width lamp 4 is turned on when driving at night, and the step lamp 5 illuminates the step 32 and the road surface of the foot when the passenger door 30 is opened and closed, so that the operator can safely get on and off the control section of the tractor 10. Can do. Furthermore, the front lighting device 1 is not dazzled by the light shielding plate 6.

上記のように前部灯火装置１を構成したため、キャビン２０の前部フレーム２１の中途部にブラケット８を取付け、該ブラケット８に前方方向指示器２、側方方向指示器３を一体に装着することができた。それにより取付け部材の削減ができると共に、側方方向指示器３を比較的車体の低い位置に配設可能となり、前方方向指示器２、後方方向指示器４０と相俟って各方向への方向指示器２，３，３６の被視認性を向上させることができる。   Since the front lighting device 1 is configured as described above, the bracket 8 is attached to the middle portion of the front frame 21 of the cabin 20, and the front direction indicator 2 and the side direction indicator 3 are integrally attached to the bracket 8. I was able to. As a result, the number of mounting members can be reduced, and the side direction indicator 3 can be disposed at a relatively low position on the vehicle body, and the direction in each direction is combined with the front direction indicator 2 and the rear direction indicator 40. The visibility of the indicators 2, 3, and 36 can be improved.

また、ブラケット８に車幅灯４及びステップランプ５をも一体に装着することによって、より一層の取付け部材の削減を図ることができると共に、省エネ性、装着性及びデザイン性も向上することができる。更に、遮光板６をブラケット８の側面部の運転手側に設けたことにより、前方方向指示器２もしくは車幅灯４の照射光によってオペレータが眩惑することも防止することができる。   Moreover, by attaching the vehicle width lamp 4 and the step lamp 5 to the bracket 8 as well, it is possible to further reduce the number of mounting members, and to improve the energy saving, the mountability and the design. . Further, by providing the light shielding plate 6 on the driver side of the side surface portion of the bracket 8, it is possible to prevent the operator from being dazzled by the irradiation light of the front direction indicator 2 or the vehicle width lamp 4.
