By using a plurality of nuts as the adjusting member, it is possible to prevent the protruding length of the adjusting member from changing due to the rotation of the nut due to an external force such as vibration. Alternatively, the insertion hole may be formed so that the cross-sectional shape thereof is similar to the cross-sectional shape of the nut, and the insertion hole may be fixed by holding the nut so as not to rotate.

  Although the fixing member according to the present embodiment has been described as a nut and a plate that supports the nut, the fixing member is provided from the direction perpendicular to the longitudinal direction by providing a hole in the side surface of the weight main body without using the nut. The adjusting member may be fixed by inserting a screw as described above into pressure contact with the adjusting member.

  In the present embodiment, the shaft tube and the weight are described as having a single configuration. However, a configuration in which a plurality of shaft tubes are connected may be used, or a plurality of weights may be connected to adjust the mass. It may be configured. When there are a plurality of weights, the length of the gap can be adjusted if at least one weight is the weight according to the present embodiment.

  Further, the insertion of the weight into the well body portion in the wall and the shaft tube may use either the end of the weight or the end of the adjustment member as the tip. Here, when the end of the weight is inserted into the inner wall well body and the shaft tube with the end as the tip, the hook 20c shown in FIG. 4 is attached to the end of the adjusting member 21 on the side not inserted into the insertion hole of the weight body 20. Provided.

  As described above, the in-wall well-establishing structure according to the above-described embodiment is useful, for example, for using a weight that adjusts the mass for deposition.
