動の周波数を相対的に高くとることができる。 As a result, the four support springs 29 and the four oil dampers 30 can reduce vibrations propagated to the head guard assembly 21, thereby improving riding comfort for the operator. Recess 2 in leg 26 of head guard assembly 21
7 and the recess 28 of the vehicle body frame 20, the support spring 29 and the oil damper 30 are attached to the recess 27 and the recess 28.
The support spring 2 is housed between the head guard assembly 21 and the support spring 2, so that it does not protrude to the outside and eliminates unnecessary protrusions.
9. The distance between the vehicle body frame 20 and the head guard assembly 21 is shorter than the height of the oil damper 30, and the absence of the aforementioned protrusions makes it easier to get on and off the head guard assembly 21. .
Since the legs 26 are provided on each of the front left and right sides and the rear left and right sides of the head guard assembly 21, the support span of the head guard assembly 21 to the vehicle body frame 20 is increased, and the frequency of pitching vibration, which is a problem when starting and stopping, is reduced. It can be taken as high as possible.
以下、本考案の実施例を第１図乃至第３図に基
づいて説明する。
Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

２にシート２３、ハンドル２４等が組み込まれて
いる。ヘツドガード組立体２１は防振機構２５に
より車体フレーム２０に支持されている。 FIG. 1 shows a side view of an industrial vehicle equipped with a cab support structure according to the present invention. In the figure, 20 is a vehicle body frame, and 21 is a head guard assembly. This head guard assembly 21 includes a box-shaped head guard section 22.
2, a seat 23, a handle 24, etc. are incorporated. The head guard assembly 21 is supported by the vehicle body frame 20 by a vibration isolating mechanism 25.
これら防振機構２５はヘツドガード組立体２１
の前後部に左右側に各一組当てに設けてある。そ
して、防振機構２５の装着はヘツドガード部２２
の前、後の脚部２６の下端の空洞部分Ａを利用し
てなされている。 These anti-vibration mechanisms 25 are connected to the head guard assembly 21.
One pair each on the left and right sides are provided at the front and rear of the. The vibration isolation mechanism 25 is attached to the head guard portion 22.
This is done by utilizing the hollow portions A at the lower ends of the front and rear legs 26.
すなわち、前記脚部２６の下面部には凹部２７
が形成してあり、また車体フレーム２０にも凹部
２８が形成してあつて、両凹部２７，２８間に支
持ばね２９とオイルダンパ３０とが介装してあ
る。 That is, a recess 27 is formed on the lower surface of the leg 26.
A recess 28 is also formed in the vehicle body frame 20, and a support spring 29 and an oil damper 30 are interposed between the recesses 27 and 28.
しかして、防振機構２５を従来空洞であつたヘ
ツドガード部２２の脚部２６の内部を利用したの
で余分な突起などがなくなる。 Since the vibration isolating mechanism 25 utilizes the inside of the leg portion 26 of the head guard portion 22, which was conventionally hollow, unnecessary protrusions and the like are eliminated.
また、防振機構２５間スパン（マウント間スパ
ン）が大きいので発進、停止時問題となるピツチ
ング振動（第３図参照）の周波数を相対的に高く
とることができる。 Furthermore, since the span between the vibration isolation mechanisms 25 (the span between the mounts) is large, the frequency of pitting vibration (see FIG. 3), which becomes a problem when starting and stopping, can be made relatively high.
４つの支持ばね２９と４つのオイルダンパ３０
