重によって位置を維持させる構造であった。Conventionally, the roof structure of this type of work vehicle was
A high position, such as that shown in Publication No. 14718,
In other words, the roof could be maintained in a fixed position only in the working position, and the roof could be maintained in position by its own weight in the lowered storage position.

リンク機構の寿命を早め易い不都合があった。However, when using a tractor in an orchard or a greenhouse, for example, the roof must be in a lowered position, but the roof bounces or rattles when traveling on uneven roads, causing noise and sliding. There are disadvantages in that the life of the parallel four-speed link mechanism on the roof of the work vehicle is likely to be shortened, such as the moving parts wear out quickly and the contact parts deform.
本発明は上記不都合を解消することを目的とする。The present invention aims to solve the above-mentioned disadvantages.

る事を特徴とする。In order to achieve the above object, the present invention provides a locking mechanism for fixing the roof in each of the two postures by relatively fixing the pair of swinging members in the roof structure of the work vehicle described at the beginning. In this structure, a hook having a hook shape in a plan view is pivotally supported on one member of the pair of swinging members so as to be swingable in the left and right directions around an axis along the longitudinal direction of the swinging member, and the hook has a hook shape in a plan view. The second swing member is characterized in that the other swing member is provided with an engagement member that can be engaged with the distal end portion in both the postures.

に形成してあるものであっても良い。Alternatively, in configuring a locking mechanism for positionally fixing the roof in each of the two postures by relatively fixing the pair of swinging members, one member of the pair of swinging members is provided with a left and right axis. Can be swung up and down around the center.
Further, a hook having a hook shape when viewed from the side is pivotally supported so as to be slidable in the axial direction, and the tip of the hook extends toward the other swinging member, and the hook extends from the side surface of the other swinging member. An engaging member capable of engaging with the tip member in both the postures is protruded in a cantilevered manner, and slides into contact with the hook as the pair of swinging members move relative to each other, and the hook engages with the engaging member. The other swinging member may be provided with an inclined guide portion for slidingly moving the hook along the left-right axis so as to be able to engage with the mating member.

として構成することが可能である。(El) In the locking mechanism of claim 1, since the hook is swung in the left-right direction to engage and release the engaging portion, the hook is moved in the left-right direction to engage and release the engaging portion. If the engagement is released, the hook and the engaging part will be shifted in their relative positions in the vertical direction and will no longer interfere with each other. Therefore, in order to change the attitude of the roof only by releasing the engagement, the link mechanism must be operated to swing. It can be made possible. Furthermore, because the hook and the engaging member do not interfere with each other while the link mechanism is moving due to the above-mentioned reason, the engaging part in both positions is made longer in the longitudinal direction of the swinging member and integrated, so that they can be constructed as one piece. It is possible to do so.

Since it can be moved in the axial direction, it can be operated so that the hook and the engaging part do not interfere even if the engagement is released and the link mechanism is moved.In addition, by providing an inclined guide, the roof can be locked. If the hook is moved to the position, the hook will automatically move laterally, and as a result, the hook can be engaged with the engaging portion only by swinging in the vertical direction without any operation to move the hook laterally. can.
