Since this idea has the above-mentioned configuration, the first
In the embodiment, after adjusting the screwing position of the elongated nut 23 to the ring bolt 22 to such an extent that the upper surface of the cam 25 substantially contacts the lower surface of the lower bracket 26, the lever 24 is rotated to form the screw as shown in FIG. When the pin P is set at this position, the pin P is pressed downward by the maximum thickness part t of the cam 25, so that the long nut 2
3 itself is prevented from rotating between the forks k of the lower bracket 26, and is pulled and tensioned toward the fan case F side. Everything is in a state of being strongly connected as one, and the lever 24
When the pin P is rotated in the direction of the arrow y1 or y2 in FIG. 3 and the pressure on the pin P by the cam 25 is released, the drug tank T and the fan case F are placed in a relaxed state. Note that by pulling the lever 24 to the right in FIG. 1 and removing the long nut 23 from the space g around the support shaft d, the screwing position of the ring bolt 22 into the long nut 23 can be adjusted. Since it can be adjusted as appropriate, it is possible to easily and appropriately deal with errors in assembling each part, wear of parts due to use over time, changes in fastening conditions, etc., and it is particularly easy for the operator to handle. In addition, there is no need to worry about losing parts such as bolts and nuts during assembly, and there is no need to use tools such as spanners and screwdrivers when adjusting them. Since it has a structure in which a cam with an inclined edge is attached to the lower surface of the pin to a long nut screwed into the pin, there is no need to complicate the structure, and it can be manufactured robustly and inexpensively. It has real benefits.
