PROBLEM TO BE SOLVED: To enable a fixing mechanism for a rotatable linking part that makes two members fixable with a screw in any desired rotating position to generate frictional force against large rotational force in a configuration that can be easily machined.SOLUTION: A fixing mechanism has a first member 11 and a second member 12 enabled to be fixed with screws in any desired rotating position and two opposing faces 11b and 12b formed around the screw hole of a fastening screw 13 that is thread-inserted between the two members to form frictional faces 11c and 12c in face contact with each other and pressed by the fastening screw. The frictional faces are formed on the outer circumferential parts of the opposing faces to be not greater than the half of the diametric length from the outer circumference of the opposing faces to the circumferential wall of the screw hole, and constitute separated parts that are not brought into contact with each other within the contacting frictional faces even by the tightening of the fastening screw.SELECTED DRAWING: Figure 1 |
