Abstract: A structure for fixing a planting base 100 supporting a planted raising member 106 by a bottom plate 101 to a laying face 300, the structure being provided with a cylinder portion 105 which projects from the bottom plate 101 of the planting base 100 to a top side and top and bottom of which are opened in which an inner diameter is gradually contracted from a top end to a bottom side, a bolt 110 constituting a fixing member is inserted to the cylinder portion 105, the bolt 110 is screwed to and fixed by an anchor holder 120 of the laying face 300 until a position at which a bolt head portion 110a is brought into contact with and caught by an inner face of the cylinder portion 105, and a top face of the bolt head portion 110a is arranged at a height the same as that of a top end of the cylinder portion 105, or arranged at inside of the cylinder portion 105.

Abstract: A greening structure comprising a plant-cultivatable planting portion on a water-reserving portion and laid on a pavement for forming a greening area. The greening structure further comprises post-shaped members provided substantially consecutively from a portion where an external force loaded on the planting portion is directly received, to the bottom of the water-reserving portion or to the pavement, so that the external force loaded on the planting portion is received on the pavement through the post-shaped members. The greening structure is excellent in the supporting strength and the stability to provide a satisfactory treading feel. The substantially consecutive post-shaped members include: first post-shaped members disposed upward from the bottom of the planting portion; and second post-shaped members disposed downward from the bottom of the planting portion.
