DECOMPOSITION TOOL
Document Type and Number:
Japanese Patent JP2017100263
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a decomposition tool in which a first member can be properly pulled out from a second member even when a thickness of an end part of the first member is small.SOLUTION: A decomposition tool 1 comprises a bolt member 2 and a base member 3. The base member 3 of the decomposition tool 1 comprises: a holding part 6 for sandwiching an end part of a first member 4 from both sides of a pull-out direction side and an opposite direction of the pull-out direction, for holding the end part; and a bolt hole part 7 which is aligned to a bolt through hole 12 provided on the end part of the first member 4 and to which the bolt member 2 is screwed. When the base member 3 of the decomposition tool 1 is attached to the end part of the first member 4, then the bolt member 2 is screwed to the bolt hole part 7, a tip end part of the bolt member 2 penetrates the bolt through hole 12 of the first member 4, then contacts a bolt contact surface 13 of a second member 5 on a position corresponding to the bolt through hole 12. In the state, when the bolt member 2 is further rotated to a screw fastening direction, the first member 4 can be pulled out from the second member 5.SELECTED DRAWING: Figure 4
