The magnetic poles are arranged so that the opposite poles face each other so as to meet each other. The first member 21 and the second member 22 are fixed so as not to be easily separated by the magnetic attraction means formed in this way.
In the above configuration, when the angle formed by the axis of the second member 22 and the first member 21 is changed, the fixed state between the first member and the second member is applied with a force larger than the attractive force by the magnets 212 and 222. In a state where the first member and the second member form a desired angle, the hemispherical convex coupling portion 211 at the lower end of the first member is replaced with the concave concave coupling portion on the upper surface of the second member 22. After being fitted into 221, the first member and the second member are fixed again by the attractive force of the magnets 212 and 222.

FIG. 3 shows an exploded perspective view of an embodiment of the leg 2.
As shown in FIG. 3, the first member 21 includes a cylindrical upper member 213 made of a resinous material, an annular magnet 212, and a convex connecting portion 211 made of a resinous material, which are connected substantially coaxially. Has been fixed. A shaft projecting upward from the convex connecting portion 211 is inserted into the central hole of the magnet 212, and is further fitted into a central hole formed in the lower surface of the upper member 213. The member 213, the magnet 212, and the convex connecting portion 211) are connected and fixed to each other.
The upper surface of the upper member 213 is fixed to the bottom surface of the housing 1 via a notch mechanism (not shown).
Note that the first member is not limited to a columnar shape, and various shapes such as a truncated cone shape, a polygonal column shape, a polygonal frustum shape, a substantially spherical shape, a bent rod shape, and a branch shape are possible. In addition, the second member is not limited to a disk shape, but may have various shapes such as a truncated cone shape, a polygonal plate shape, a polygonal truncated cone shape, and a hemispherical shape.

The 2nd member 22 is comprised from the base 223 in which the said concave connection part 221 was formed, and the magnet 222 engage | inserted by the hollow formed in the lower surface of the base 223 which consists of a resinous material.
When the second member 22 is brought close to the first member 21, the magnet 222 of the second member 22 and the magnet 212 of the first member 21 attract each other, so that the second member 22 is the first member 21. It is adsorbed by the lower end of the plate and is not easily separated.

As shown in FIGS. 4A and 4B, a plurality of small protrusions 215 are formed on the surface of the convex connection portion 211 of the first member 21, and the corresponding second member 22 has A small concave hole 225 into which the small protrusion 215 can be fitted is formed on the surface of the concave connecting portion 221. At this time, the mutual positional relationship between the plurality of small protrusions and the mutual positional relationship between the plurality of small concave holes are equal to each other even when the angle between the first member and the second member is changed. And a small concave hole can be fitted.
Therefore, in a state where the second member 22 and the first member 21 are attracted and connected, the small protrusion 215 on the first member 21 side is fitted in the small concave hole 225 on the second member 22 side. And the relative positional relationship is not easily removed.

The rod body 53 was formed. The concave connection portion 52 is configured to fit at least a part of the convex connection portion 51. In addition, small protrusions are formed on the surface of the convex connection part 51, small concave holes are formed on the surface of the concave connection part, and the relative positional relationship does not deviate by fitting the irregularities together. Like that.

As shown in FIG. 11, it is also possible to use the connection body 5 having the above structure by sequentially connecting to the other connection bodies 6 and 7. In this case, the convex connecting portion 61 of the base connecting body 6 is fitted and connected to the concave connecting portion 81 of the fixing member 8 fixed to the wall surface, and the housing connecting plate 7 is connected to the front connecting body 7. A support structure that can support the housing at a free angle can be realized by fixing and attaching 71 and fixing a housing (not shown) to be supported to the housing fixing plate 71.
