PROBLEM TO BE SOLVED: To stably support a strut by adjusting a support part to an arbitrary angle. SOLUTION: A strut support 21 includes: a pile part 22 driven in the earth or the like; and a support part 23 supporting the strut extended upward in the state of being fitted to the upper side of the pile part 22. The upper end part of the pile part 22 is provided with a lower curved surface plate 26. The lower end part of the support part 23 is provided with an upper curved surface plate 31 turning the strut in an arbitrary direction in alignment with the lower curved surface plate 26 of the pile part 22. The lower curved surface plate 26 and the upper curved surface plate 31 are formed by a spherical plate piece. A bolt hole 34 is formed larger than the hole of a nut 28, and a washer 35 larger than the bolt hole 34 is provided to cover the bolt hole 34. A driving surface 29 for driving the pile part 22 in the earth or the like is provided at the central part of the lower curved surface plate 26. COPYRIGHT: (C)2004,JPO
