造に関する。[Detailed description of the invention] [Field of industrial application] The present invention relates to a tractor body structure that improves the ride comfort of the driver. A tunnel-like housing part is bored upward through which a transmission shaft from the rear hydrostatic oil stage transmission is inserted, and a gear change pedal linked to the continuously variable transmission is disposed on one side of the housing part. This article relates to the body structure of the tractor.

[Conventional technology]

この種のトラクタの車体構造としては、例えば
実開昭56−106972号公報で示すように、ハウジン

席左右の中心と重なり合うように夫々を配置して
ある。 As shown in, for example, Japanese Utility Model Application No. 56-106972, the body structure of this type of tractor has a housing portion disposed along the center line of the width of the body. In other words, the housing parts are arranged so that the center line in the width direction overlaps with the center of the left and right sides of the seat.

[Problem that the invention attempts to solve]

しかし乍ら、上述の如くハウジング部と座席と
を配置したことによつて次のような不都合が生じ
ていた。即ち、静油圧式の無段変速装置を装備し
たトラクタにあつては変速ペダルを固定して定速

足をハウジング部の両側のステツプに置いて運転
することになるが、ハウジング部の横側には変速
ペダルを配設してあるため、そちら側のステツプ
側に置いた方の足は変速ペダルが邪魔になつて幾
分開き気味になつてしまう。そしてそれが元で運
転者の運転姿勢が次第に崩れていってしまうので
ある。 However, the following inconveniences have arisen due to the arrangement of the housing portion and the seat as described above. In other words, tractors equipped with hydrostatic continuously variable transmissions are often driven at a constant speed with the gear change pedal fixed, and in that case, the driver places both feet on the steps on both sides of the housing. When driving, the gear shift pedal is placed on the side of the housing, so the foot placed on the step side of the housing gets in the way and tends to open slightly. Put it away. This causes the driver's driving posture to gradually deteriorate.

そこで、本考案はこのような点に着目し、運転
者が左右対照にステツプを踏めるようにすること
によつて運転姿勢を良くし、楽に運転を行えるよ
うにすることを目的としている。 Therefore, the present invention focuses on this point and aims to improve the driving posture by allowing the driver to take steps symmetrically to the left and right, thereby allowing the driver to drive comfortably.

[Means for solving problems]

上記目的を達成するためになされた本考案の特
徴構成は、ハウジング部を座席の左右中心より変
速ペダル配設側と反対の横側方に偏位して設けて
ある点にあり、その作用・効果は次のとおりであ
る。 The characteristic configuration of the present invention, which has been made to achieve the above object, is that the housing portion is provided offset from the left-right center of the seat to the side opposite to the side where the speed change pedal is disposed. The effects are as follows.

[Effect]

つまり、ハウジング部を偏位した分変速ペダル
を中心側へ寄せることで、変速ペダルを避けて足
を外側のステツプに置いても両足を均等に開くこ
とができるのである。 In other words, by moving the gear shift pedal closer to the center by the amount that the housing part is displaced, it is possible to spread both feet equally even if you avoid the gear shift pedal and place your feet on the outside steps.

[Effect of idea]

従つて本考案によれば、運転者が左右対称に足
を開いてステツプを踏むことができるので運転姿
勢が良くなり、楽に運転を行えるようになつた。 Therefore, according to the present invention, the driver can spread his legs symmetrically and step on the steps, which improves his driving posture and allows him to drive comfortably.

An engine 4 is disposed within a bonnet 3 at the front of the fuselage supported by an engine 2, a clutch housing 5 is connected to the rear of the engine 4, and the clutch housing 5 and transmission case 6 are configured in a tunnel shape. connected by the housing part 7,
A hydrostatic continuously variable transmission 8 attached to the output shaft of the clutch housing 5 and the front of the transmission case 6
(hereinafter referred to as HST) is interlocked and connected via a transmission shaft 9.

２に足を置けるようになつている。 As shown in FIG. 1, the transmission shaft 9 is inserted through the inside of the housing part 7, and a speed change pedal 10 linked to the HST 8 is disposed on the right side of the housing part 7. It has been done. and,
The center line _l1 in the width direction of the housing part 7 is offset from the left-right center line _l2 of the seat 11 to the side opposite to the side where the speed change pedal is disposed, that is, slightly to the left of the center in the width direction of the aircraft body, As a result, even if the driver avoids the gear shift pedal 10, the driver can spread his left and right feet evenly and take the left and right steps 1.
You can put your feet on 2.
