Document Type and Number:
Japanese Patent JP2007046779
Kind Code:

Abstract:

To provide an assembly which is easily disassembled and fastened and a structure which is easily disassembled and fastened which do not need the control of fastening torque at the time of fastening, and which make secure operation possible.

The assembly which is easily disassembled and fastened is constituted by attaching one member having a through hole for a male screw to the female screw part of the other member having the female screw part with the male screw and a washer. The male screw has an intermediate part between the male screw part and the head having a larger diameter than the male screw part, and the intermediate part, which is provided by forming a level difference with the male screw part, has a diameter which is larger than the outer diameter of the male screw part and smaller than the diameter of the head. Then the washer is arranged between the side of the male screw part of the head of the male screw and the other member. The washer has an inner diameter, which is larger than the diameter of the intermediate part of the male screw and smaller than the diameter of the head of the male screw, and an outer diameter which is larger than the diameter of the head of the male screw. When the washer is heated to predetermined temperature or more, it is deformed and the inner diameter of the washer becomes larger than or equal to the diameter of the head of the male screw.
