An inclined side end portion 15 that is tapered toward the end portion 14 is provided. And in this embodiment, although the said blade part 12 is formed in the right-angled equilateral triangle shape, it is not limited to this shape in particular, As shown in FIG. The extended portion 16 having both end portions parallel to each other may be formed at the base of the right-angled equilateral triangular blade portion 12 to form a trapezoidal blade portion 12 as a whole. A small right-angled equilateral triangular blade portion 12 may be formed. In short, the lower end portion of the column main body 11 is cut out by an appropriate means such as a press or a laser beam, leaving a portion to be the blade portion 12, and is projected below the column main body 11 as a single body, not a separate body. The plurality of blade portions 12 may be formed at intervals in the circumferential direction.

  The shape of the blade portion 12 may be a U-shape, a rectangle, or the like as shown in FIGS. 6 and 7, or a combination of them to form a right-angled triangular blade portion 12 and a U-shaped blade portion.
