The first direction Y is parallel to the width direction of the base plate 11, and the first direction Y is perpendicular to the second direction X.

In order to even out the forces exerted on the base plate 11, the plurality of connecting columns 12 are also rotationally symmetrical about the first center line X1. The first center line X1 is perpendicular to the bottom plate 11 and passes through a midpoint of a center line of the bottom plate 11 extending along the first direction Y.
