操作部３に設けて構成した。(Means for Solving the Problems) The present invention has been made in view of the above circumstances, and even if the required rotation angle (θ) of the operating lever 2 is large in order to put the operated tool 1 into the operating state, In order to provide a lever operating mechanism that does not require any particular increase in the length of the guide groove 4', the lever operation mechanism is constructed as follows.
That is, the elongated guide groove 4 in which the grip portion 15 of the operating lever 2 pivoted on the pivot portion 5 is formed in the operating portion 3.
At a position where the operating lever 2 is brought into contact with the groove ends 6 and 7 of the guide groove 4, the operated tool 1 linked to the operating lever 2 is held in an operating position C and a non-operating position D. In the lever operating mechanism, the operating lever 2 is bent in a dogleg shape in the direction of the guide groove 4 at the intermediate portion, and both groove ends 6 and 7 of the guide groove 4 are bent at the base with respect to the bending point P of the operating lever 2. A guide groove 4 is provided in the operating part 3 so that the guide groove 4 comes into contact with the side and the tip side separately.

At the time of switching, the operating lever 2 Both groove ends 6, 7 of the guide groove 4 alternately on the base side and the tip side with respect to the bending point P of 2.
It will be held in contact with the When the required rotation angle of the operating lever 2 is the same angle (θ) as in the conventional example shown in FIG. 2, the required length of the guide groove 4 is (H 1 ) in the present invention. That is, in the present invention, the length of the guide groove 4 can be shortened by the length (H-H 1 ) compared to the conventional example.
