Description of the Related Art When a three-point link type working machine mounting device is mounted on the rear part of a tractor, the top link of the three-point link is pivotally mounted on the rear part of the tractor body so as to be vertically rotatable. When the work machine attached to the rear of the three-point link type work equipment mounting device is removed, the top link is swingably mounted, so it swings during running and hits other parts, which damages those parts. A technique is known in which a hook is attached to a position where the top link is rotated upward so that the top link is fixed so that the top link is not removed, and the top link is fixed. For example, it is a technique disclosed in Japanese Patent Laid-Open No. 2000-232802. As shown in FIG. 9, the conventional hook 50 has a hook-shaped hook 50a at its tip and is made of a plated metal. Further, the inner diameter of the hook portion 50a is formed to be the same as the outer diameter of the top link 51, and while swinging the top link 51 sideways, the hook portion 50a
And fixed the top link 51.

I had to use both hands to store it with great force, and it took time to store the top link. Further, although the storage member is plated, the metal surface is engaged with the top link, so that the coating is easily peeled off, which causes rust. Moreover, since the conventional storage member has a small contact surface with the top link, it causes noise due to shaking during traveling of the tractor.

The storage member 23 is arranged at a position as close as possible. That is, as shown in FIG. 3, the lower end of the storage member 23 and the top link 20 when the lift arm 19 is maximally raised are separated by a distance L, and the distance L is reduced. The storage member 23 is arranged.

It will be described with reference to FIGS. As shown in FIG. 3, the storage member 23 is formed by bending a rod made of a steel rod or the like, and is formed in a substantially L shape in a side view. The upper portion (rear portion) of the storage member 23 serves as the storage portion 25.
Is coated or fitted with a protective member 25c made of synthetic resin, rubber or the like to protect the painted surface of the top link 20 from being scratched or peeled off due to friction or the like when the top link 20 is engaged. The member 25c is made of a softer material than the top link 20.
Further, the protective member 25c is elastic and capable of absorbing sound so that chattering noise or the like is not generated even when vibration occurs during traveling. However, when the storage member 23 is made of synthetic resin, aluminum, or the like that is softer than the top link 20, the protective member may be omitted.

It is arranged. The inner diameter of the large diameter portion 25b is substantially the same as or slightly smaller than the outer diameter of the top link 20, so that the storage portion 25
In the above, the size is set so that the top link 20 can be held so as not to rattle. The small-diameter portion 25a is provided on the inner side of the large-diameter portion 25b opposite to the open side with a spring force,
By providing the small-diameter portion 25a, the elastic force of the storage portion 25 can be reduced by providing the small-diameter portion 25a, so that the force for storing the top link 20 in the large-diameter portion 25b can be reduced. It is easy to operate when attaching and detaching. Further, since the surface pressure of the contact portion between the top link 20 and the storage portion 25 decreases, it is possible to prevent the coating of the storage portion 25 from peeling off. In this embodiment, a small diameter portion 25 smaller than the diameter of the top link is provided in front of the storage portion 25.
a is projected and the storage portion 25 has an elastic force,
However, the present invention is not limited to this.
It is also possible to adopt a configuration in which the elastic force is imparted to.
