Kind Code:
B2
Abstract:
To provide a fastening structure capable of efficiently applying a bearing pressure of a fastening bolt to a main member and a laminate member, and suppressing degradation of the efficiency in a fastening work by the fastening bolt.SOLUTION: In a fastening structure including a main member, a laminate member laminated on the main member, and a fastening bolt for fastening the main member and the laminate member, the main member includes a first insertion hole, and a second insertion hole of which the other side edge is disposed on a position separating from one side edge of the first insertion hole by a distance D1 to one side. The laminate member includes a third insertion hole, and a fourth insertion hole of which the other side edge is disposed on a position separating from one side edge of the third insertion hole by a distance D2 to one side, and of which one side edge is disposed on a position separating from the other side edge of the third insertion hole by a distance D3 to one side. The distance D1 is longer than the distance D2, and shorter than the distance D3. The fastening bolt includes a first fastening bolt constituted to be diameter-enlargeable in a state of being inserted to the first and third insertion holes, and a second fastening bolt constituted to be diameter-enlargeable in a state of being inserted to the second and fourth insertion holes.SELECTED DRAWING: Figure 1
