Japanese Patent JP3769743
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To facilitate fitting of a fixing machine screw and prevent slip-off of the screw by forming such a structure that one or more through-holes move in a nearly orthogonal direction to a hole axis, in relation to the other hole and move in the direction of shifting the center of each axial hole after insertion of the machine screw.
SOLUTION: At the time of inserting a fixing machine screw 3, the center axis of a through-hole part of a first member 2a of an optional unit 2, and the center axis of a through-hole of a second member 2b are adjusted to each other to penetrate the second member 2b with an external thread part 7. At this time, the center axis of a machine screw hole of the first member 2a, and the center axis of a machine screw hole of the second member 2b are offset from each other. Either the center axis of the through-hole of the first member 2a or the center axis of the second member 2b are then shifted. The external thread part 7 of the fixing machine screw 3 thereby comes in contact with a step part 2c of the second member 2b so as to prevent slip-off of the fixing machine screw 3, and a connecting machine screw 8 is fastened into a machine screw hole 4 to fix the first member 2a and the second member 2b to each other.
