PROBLEM TO BE SOLVED: To prevent a positional displacement when a component is fixed by a screw without increasing a manufacturing cost.SOLUTION: This invention relates to a fixing structure in which a base end part of a plate-like blade member 42 is inserted into a hollow inner side through a long hole 22a of an upper frame 22 and a right screw is fastened through a screw insertion hole 42b of the blade member 42 against a thread hole 61a of a fixing surface 61b arranged at the upper frame 22, the extremity end part is protruded out of the long hole 22a, and the blade member 42 is supported by the upper frame 22 under an attitude in which the extremity end is oriented to cross at a right angle with respect to a longitudinal direction of the upper frame 22. The long hole 22a is eccentrically formed with respect to the thread hole 61a of the fixing surface 61b, thereby a distance between the right side surface 42c of the blade member 42 and one end surface 22aA of the long hole 22a is made shorter than a distance between the left side surface 42d of the blade member 42 and the other end surface 22aB of the long hole 22a under the fixing attitude.SELECTED DRAWING: Figure 7 |
