PURPOSE: To provide a frame structure of an intermediate device or the like for proximity photographing and whose extending out distance is made large and which is capable of compactly housing at a housing time.

CONSTITUTION: This frame structure for proximity photographing is provided with a first cylindrical frame member 3, a second frame member 4 constituted so that it can be moved in a direction along a cylindrical center with respect to the first frame member 3, a third frame member 6 constituted so that it can be moved in the direction along the cylindrical center with respect to the second frame member 4, flexible members 28 and 29 whose both ends are fixed to the first and the third frame members 3 and 6 and which is provided with flexibility and formed to be linear or belt-like, direction change members 11 and 16 being pulleys provided on the second frame member 4, to invert the extending direction of the flexible members 28 and 29, and constituted so as to be freely rotated, and an energizing member giving tensile force to the flexible members 28 and 29. Further, it is arranged between a camera body and a lens barrel.
