2. Description of the Related Art As this kind of column height adjusting mechanism,
For example, there is one disclosed in JP-A-6-339415. That is, a receiving bracket is formed by a substantially square bottom plate portion that receives the lower end of the rectangular column, and a vertical plate portion that stands upward from two mutually parallel sides of four sides of the outer peripheral edge of the bottom plate portion. The support metal height adjusting mechanism is constituted by the receiving metal fitting and an adjuster screwed into a screw hole formed in the center of the bottom plate portion. A plurality of projections are formed on the outer surface of each of the pair of vertical plate portions of the receiving metal fitting so as to be engaged with a plurality of through holes formed in the column, and the column is formed on the pair of vertical plate portions from above. By externally fitting, the convex portion is engaged with the through hole of the column to complete the fixing between the receiving bracket and the column.

According to the above configuration, not only must a plurality of protrusions and a plurality of through-holes be formed for fixing the receiving bracket and the support, but also a plurality of protrusions and a plurality of through-holes must be accurately formed. It has to be formed, resulting in high cost.
In addition, since the support is externally fitted to the support, the support can be made excellent in design without being exposed to the outside. , There was a negative in that point. Further, the configuration is such that the load from the column is received by the pair of vertical plates, but the load cannot be received by only one of the vertical plates depending on the direction of the load, so that a large load cannot be received. Incidentally, it is conceivable to increase the thickness of the receiving fitting so as to be able to receive a large load. However, it is disadvantageous in terms of material cost, processing, and handling, and is difficult to implement.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention is intended to solve the above-mentioned problem, while suppressing an increase in cost and preventing the receiving bracket from being exposed to the outside. Another object of the present invention is to provide a column height adjusting mechanism capable of reliably receiving a large load while suppressing an increase in weight.

The receiving bracket and the support are fitted so that the outer surfaces of the other second vertical plate portions except for the first vertical plate portion abut on the inner surfaces of the two second vertical wall portions. Therefore, in a state where the receiving bracket and the support are fitted, when the support is viewed with the first vertical plate portion facing the front,
The first vertical wall portion is located on the inner surface side of the first vertical plate portion,
Since the two second vertical wall portions are located behind the left and right widths of the first vertical plate portion, the first vertical wall portion and the two second vertical wall portions cannot be seen. And, by forming the strut and the receiving bracket into a substantially triangular shape, the strut and the receiving bracket are less likely to buckle due to the strut action from three directions, as compared with the case where they are formed in a quadrangular shape, and from the second vertical plate portion. A large load receiving area can be secured in the second vertical wall portion, and a large load can be endured.
In addition, it is possible to fix both of them simply by fitting the receiving fitting and the support.

In a state in which the receiving fitting and the support are fitted, the outer surface of the first vertical wall portion is provided on each of the inner surfaces of the inner surface of the first vertical plate portion located at both ends on the second vertical plate portion side. Abuts, and the outer surface of the first vertical wall portion projects outwardly toward the middle portion so that the inner surface is not in contact with the outer surface of the first vertical wall portion,
By allowing the first vertical plate portion to protrude outward when the receiving fitting and the support are fitted, when there is some dimensional error in the receiving fitting and the support, or when the fitting of the both is performed. Even if you set both dimensions to be strong,
Since the first vertical plate portion can be protruded and deformed outward when the receiving fitting and the support are fitted, the above-mentioned slight dimensional error can be absorbed and both can be forcibly fitted. is there.
