あつた。 This mechanism consists of an adjustment rod 4, a nut 5 and a screw hole 2.
serves as a double lock, and by changing the amount of tightening torque of the nut 5, the amount of stress applied to the adjustment rod 4 can be freely changed. Further, in order to prevent the nut 5 from loosening during rotation of the adjustment rod 4, a pawl 6 provided on the nut 5 is inserted into a detent groove 3 provided in the cabinet case 1. However, this mechanism has a drawback in that it requires adjustment of the tightening torque of the nut 5 with respect to the adjustment rod 4.
本考案の目的は調整棒取付機構の回転トルクの

によつて全く影響されないように制限してある。 FIG. 3 is a perspective view of a cavity resonator according to an embodiment of the present invention, and FIG. 4 is an enlarged explanatory view showing an adjustment rod attachment mechanism of the present invention. In the figure, 1 is a cavity case, 7 is a mounting hole provided in the cavity case, 4 is an adjustment rod with a male thread over the entire length, and 8
are the screw hole 4a into which the adjustment rod 4 is screwed, and the male screw 4 used when installing it to the cavity case 1.
b and a flange 4c, the tip thereof is provided with a slit 9 having a certain width and a certain length, and 10 is a nut for tightening the adjustment rod guide 8 to the cavity case 1. It is. In this adjustment rod mounting mechanism, the adjustment rod guide 8 is tightened and fixed to the cavity case 1 with a nut 10, and the adjustment rod 4 is screwed into the adjustment rod guide 8. In order to rotate the adjustment rod 4 smoothly with a constant rotational torque, the adjustment rod guide 8 must be set in advance before screwing in the adjustment rod 4.
By adjusting the distance between the slits 9 to a certain fixed amount, it is possible to optimize the frictional force at the threaded joint into which the adjustment rod 4 is screwed. The position of the slit 9 is limited so that it is not affected at all by the tightening force when the adjusting rod guide 8 is tightened and fixed to the cavity case 1 with the nut 10.
