The moving side member A1 is urged toward the door end portion 10A.
That is, according to the coil spring A36 of this embodiment, since the moving side member A1 is urged in the direction of the door end 10A, the moving side member A1 is turned into the coil spring by rotating the screwing member A3 in the tightening direction. By moving in the direction of the fixed side member A2 against the urging force of A36 and rotating the screwing member A3 in the loosening direction, the moving side member A1 moves in the direction of the door end 10A by the urging force of the coil spring A36. Therefore, the clearance gap between movement side member A1 and door tip part 10A can be adjusted.

Further, the coil spring A36 in the present embodiment contracts the moving force in the direction of the fixed side member A2 acting on the moving side member A1 when an impact force or the like is applied to the moving side member A1 from the outside. Since it absorbs, it functions also as a buffer material which prevents the movement side member A1 from being damaged or deformed.
Further, the coil spring A36 according to the present embodiment urges the moving side member A1 in the direction of the door end portion 10A, thereby engaging the engaging portion A34 and the support plate A31 in the screwing member A3 screwed to the fixed side member A2. Therefore, it also functions as a loosening prevention material for preventing loosening of the screwing member A3 screwed to the fixed side member A2.
The biasing means in the present invention can be applied to various types of springs such as leaf springs other than the illustrated coil spring, or a pressing force of elastic rubber material, elastic synthetic resin material, magnets repelling each other, etc. On the other hand, a means in which a repulsive force acts may be used.
Further, the biasing means may be provided in a part other than the illustrated screw part A33 as long as the moving member A1 can be biased in the direction of the door end 10A. For example, the biasing means may be provided with the coil spring A36. When using as, the effect similar to the form illustrated by providing the end so that it may contact | abut to the bottom face part 21B in the fitting recessed part 21A, and the other end may contact | abut to the back side of the to-be-adjusted part side A11 can be acquired.
