い。The vehicle-side connecting tool and the working machine-side connecting tool are connecting tools such as a hydraulic circuit and an electric circuit, which are connected to each other by pressing one connecting tool toward the other connecting tool. A rapid joint can be used for both of the above-mentioned connecting tools, and in this case, once connected, this connection can be maintained even if the pressing force is released. However, it is also possible to use a joint that is connected to the connecting tool of the present invention only while pressure is applied by holding the vehicle side support means in the advanced state. In this case, it is more preferable that the connection between the two connecting tools can be easily released by retracting the vehicle-side supporting means, and the detaching operation of the working machine can be simplified.

Is a structure for moving the vehicle-side supporting means by driving the vehicle. Although an electric motor or the like can be used as the above actuator, if a hydraulic cylinder is used, it can be pressed with a substantially constant pressure even if the working machine side support means moves a little due to vibration, etc., and the connection state is maintained well. It is more preferable because it can.

Although a configuration is also conceivable, if an elastic body such as a spring is placed between the surrounding frame and the work implement side support means to support the work implement side support means, the work equipment side support means is fixed to a constant neutral position before being mounted on the work vehicle. It is more preferable because it can be held at It should be noted that the elastic means for elastically pressing the working machine side supporting means refers to an elastic body such as rubber or a spring.However, when a spring is used, the amount of expansion and contraction can be set larger than when rubber is used, and during operation, etc. It is more preferable because the generated vibration can be absorbed well.

Advance to the side. When the positioning means is guided by the guide means by this advance movement, the working machine side supporting means moves as necessary in the direction orthogonal to the connecting axis of the working machine side connecting tool, and the relative positions of the both supporting means. Is positioned so that the connection axis of the vehicle-side connector and the connection axis of the work implement-side connector are exactly aligned. When the vehicle-side support means further advances in a state where the two connection axes coincide with each other, the vehicle-side connection tool and the work implement-side connection tool come into contact with each other, and the elastic pressure means is pushed by the one support means. Due to the repulsive force of the elastic pressure means, both connecting tools are pressed against each other via the both supporting means, so that they are securely connected.
