As is clear from the above description, the rotation transmitting device according to the present invention has various excellent effects in practical use as listed below.

In the rotation transmitting tool according to the present invention, a front connecting member having a front gear which is a bevel gear and a rear connecting member having a rear gear which is a bevel gear are connected by a middle rod which supports the middle gear which is a bevel gear. Since the front gear and the rear gear are rotatably supported in a state in which the front gear and the rear gear mesh with each other via the middle gear, the rear connection body and the front connection body are fixed at a desired angle around the center rod. In this state, the rotational force from the rear connecting body can be transmitted to the tip tool, and it is compact and relatively weighed. Even if it is attached to the tip of the remote control rod, it can be used without impairing the operability of the remote control rod. It is easy to do.

Further, the rotation transmitting tool according to the present invention can transmit the rotational force from the rear connecting body to the tip tool in a state where the rear connecting body and the front connecting body are fixed at a desired angle around the center rod. Therefore, by connecting to the remote control rod and using it, it is possible to easily perform tightening work etc. without forcing the worker into an unreasonable posture, and also to determine the stop position of the work vehicle on which the worker rides and work. The work table does not need to be frequently moved and changed, and work can be performed efficiently.
