Abstract: front page image
(EN)

An insert includes an upper surface including at least one corner part and a plurality of side parts, and a side surface. The upper surface includes a corner region. The corner region includes a first corner surface, a second corner surface, a third corner surface, and a fourth corner surface which are located sequentially in order from a side of the corner part. The first corner surface is inclined downward. The second corner surface, the third corner surface and the fourth corner surface are inclined upward. An inclination angle θ12 of the second corner surface is greater than an inclination angle θ13 of the third corner surface. An inclination angle θ14 of the fourth corner surface is greater than the inclination angle θ12 of the second corner surface.
