てある作業車のチルトハンドル構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention pivots a handle post so that it can swing freely within a predetermined range in the longitudinal direction of the aircraft around a horizontal axis, and also controls the swing trajectory of the handle post. An engaging member that is swingable around an axis along a plane and that is equipped with an operating lever is attached to the handle post, and the swinging end of the engaging member is engaged with a locking portion on the side fixed to the fuselage. The present invention relates to a tilt handle structure for a work vehicle, which is configured to be able to fix and hold a handle post at a set position.

The tilt handle of the work vehicle is designed to allow the operator to adjust the position of the handle depending on the operator, and to move the handle to a position where it does not get in the way when getting on or off the vehicle, making it easier for the operator to get on or off the vehicle. As mentioned above, in the structure in which the engagement member provided on the handle post is engaged and disengaged using the operating lever,
There is a model in which a coil spring is installed between the engaging member and the fuselage fixing portion to urge the engaging member toward the engagement side with the locking portion.

With the above-mentioned structure, it is necessary to punch out the engaging member from a plate material and then drill a hole for installing the coil spring, and also to bend the front and rear ends into a hook shape after cutting the coil spring to a set length. Therefore, there was room for improvement in terms of reducing production costs.
ここで本考案は前述の点に着目して、ハンドル

あり、その作用及び効果は次のとおりである。
The feature of the present invention is that in the above-mentioned tilt handle structure for a work vehicle, a convex portion that is along the plane of the rocking locus of the engaging member and that faces the outer surface of the handle post is formed on the engaging member or the operating lever. One end of a coil spring provided on one side and compressed from a free state is fitted onto the convex portion, the other end is brought into contact with the outer surface of the handle post, and the engaging member is attached to the engaging side with the locking portion. The functions and effects are as follows.

As mentioned above, if a compressed coil spring is fitted onto the protrusion provided on the engaging member or the operating lever and pressed against the outer surface of the handle post, the coil spring will not come off and the coil spring will try to expand. This biasing force biases the engaging member toward engagement with the locking portion.

た状態で組み付けることができるのである。 When the engaging member is manufactured by punching from a plate material, the convex portion can be easily manufactured integrally with the engaging member, and if the convex portion is provided on the operating lever, it is possible to engage the operating lever. The convex portion can be formed by simply slightly extending the end portion attached to the mating member. Further, there is no need to provide hooks at the front and rear ends of the spring, and the spring can be assembled after being cut to a predetermined length.

As described above, it is possible to omit the drilling of holes for the coil spring in the engaging member and the bending of the hook portion of the coil spring,
It is now possible to reduce manufacturing costs without impairing the biasing function for the engaging member.
