  In addition, this invention is not limited to the said embodiment, The other modification etc. which can achieve the objective of this invention are included, and the modification as shown below is also included in this invention.

  For example, in the embodiment, the insertion holes 212 and 313 through which the shaft portions 232 and 233 of the bolt member 23 are formed are formed in the inner contact portions 21A and 21B and the outer contact portions 31A and 31B, respectively. However, the insertion hole may not be formed in the inner contact portion and the outer contact portion, and the shaft portion of the bolt member may not be inserted. That is, the nut fixed to the inside of the inner contact portion is formed to be long in the X direction, thereby making it possible to adjust the distance between the pair of inner contact portions and, for example, a bolt inserted into the through hole 314 A pair of outer contact portions may be brought close to each other by using a nut screwed to the bolt from the outside of the outer contact portion as a fixing member. According to such a configuration, it is not necessary to form the insertion holes in the projecting pieces A1 and A2, and the operation of inserting the shaft portion of the bolt member into the insertion holes can be omitted.

  In the embodiment, the pair of inner contact portions 21A and 21B come close to each other by rotating the bolt member 23 in the forward direction, and the pair of inner contact portions 21A and 21B are rotated by rotating the bolt member 23 in the opposite direction. Although they are configured to be separated from each other, the configuration of the adjustment portion that adjusts the distance between the pair of inner contact portions is not limited to this. For example, a bolt member is fixed to one inner contact portion and a shaft of the bolt member is inserted into the other inner contact portion, and a nut screwed to the bolt member is the other inner contact portion. It may be arranged without being fixed inside, and by rotating the nut, one inner abutment may be moved away from the other inner abutment. Further, the inner contact portions are not fixed by fixing the nuts 24, 25 in the embodiment to the inner contact portions 21A, 21B, and by rotating the nuts 24, 25 while preventing the bolt member 23 from rotating by a wrench or the like. 21A and 21B may be separated from each other. According to these configurations, the direction of the spiral of the shaft portion of the bolt member may be fixed, and the configuration of the bolt member can be simplified.

  Further, in the above embodiment, although the upper surface and the lower surface where the bottom portions 22A and 22B of the pair of inner members 2A and 2B overlap alternately are provided, the bottom portions of the pair of inner members 2A and 2B One may be configured to sandwich the other from the Z direction, or one may simply overlap the upper side of the other. Further, for example, if rattling when moving the inner members 21A and 21B relative to each other is sufficiently suppressed by inserting the bolt member 23 into the insertion hole 212, the inner member does not have the bottom surface portion. It is also good. Moreover, the upper surface part of a pair of outer side members 3A, 3B may overlap similarly to bottom face part 22A, 22B, and may be abbreviate | omitted.

  In the above embodiment, the inner member 2 is disposed between the pair of projecting pieces A1 and A2, but when the projecting pieces A1 and A2 have sufficient strength, or in the X direction, they are wide. When the convex portion is formed on the roof and the convex portion is sandwiched by the outer member, the inner member 2 is not used, and only the outer member 3 may be attached to the projecting pieces A1 and A2 or the convex portion. For example, the projecting pieces A1 and A2 and the convex portion may be sandwiched by the pair of outer contact portions 31A and 31B by inserting a bolt into the through holes 314 formed in the outer contact portions 31A and 31B and tightening a nut. .
