  Further, when the attachment members 41, 50, 61 are detached from the mounting main body 20, the fixing member 70 is rotated so that the screw hole insertion portion 71 rotates in a direction away from the screw hole 32 a.

  For the female screw 30 and the fixing member 70, it is preferable to select a material capable of forming a screw thread so that the screw hole insertion portion 71 functions as a male screw.

  Further, the attachment operation member 80 is held in the cylindrical space 73 so as to fill the cylindrical space 73 by being pushed into the cylindrical space 73.

Next, the procedure for fixing the attachment members 41, 50, 61 to the mounting body 20 and the operation of each part will be described with reference to FIGS.
4A is a perspective view of the fuse mounting portion 10 in which FIG. 4A shows a state where the mounting operation member 80 is temporarily locked to the fixing member 70, and FIG. 4B shows the periphery of the female screw 30 of FIG. It is sectional drawing. 5A is a perspective view of the fuse mounting portion 10 in which FIG. 5A shows a state in which the mounting operation member 80 is permanently locked to the fixing member 70, and FIG. 5B shows the periphery of the female screw 30 of FIG.

In addition, since the fixing member 70 functions as a male screw corresponding to the female screw 30, the attachment members 41, 50, 61 are detachably fixed to the mounting main body 20 and attached. It is possible to simplify the work of fixing wood 41,50,61.

  In addition, the fixing structure 1 of the mounting member according to the first embodiment of the present invention pushes the distal end portion 81 of the mounting operation member 80 forward into the wall 70a that closes the cylindrical space 73 and has a diameter larger than that of the cylindrical space 73. By the action of the large diameter portion 82 expanding the cylindrical space 73 in the radially outward direction, the screw hole insertion portion 71 can be deformed so that the outer peripheral surface 71a of the screw hole insertion portion 71 follows the inner surface 32aa of the screw hole 32a. it can.

  Further, in the mounting member fixing structure 1 according to the first embodiment of the present invention, the mounting members 41, 50, 61 can be easily detached from the mounting body 20 by rotating the flange portion 72.

(Modification)
Next, a modified example of the mounting member fixing structure 1 according to Embodiment 1 of the present invention will be described with reference to FIG.
FIG. 6 shows the main part of the fuse mounting part 100 incorporating the mounting member fixing structure 2 of the modified example of the mounting member fixing structure 1 according to the first embodiment of the present invention. It is sectional drawing which showed the internal periphery of the internal thread 30 before pushing in, (b) is sectional drawing which showed the internal periphery of the internal thread 30 after pushing in the attachment operation member 200.

Is different from the mounting member fixing structure 1 according to the first embodiment.
Other configurations are the same as those of the first embodiment, and the same components as those of the first embodiment are denoted by the same reference numerals.

  In the fixing structure 3 of the mounting member, the columnar space 403 of the fixing member 400 passes through the fixing member 400 along the axial direction of the screw hole 32a.

  Such a fixing structure 3 of the mounting member is such that when the fuse terminal 41, the connection plate 50, and the electric wire terminal 61 as the mounting member are fixed to the mounting body 20 as the mounting destination, the female screw 30 and the flange portion 72, the mounting operation member 80 is pushed into the cylindrical space 403 and penetrated through the fixing member 400 in a state where the mounting members 41, 50, and 61 overlapped with each other are sandwiched between the mounting members 41, 50, and 61.

  More specifically, the mounting operation member 80 is moved forward along the axis of the screw hole insertion portion 401, and a part of the large diameter portion 82 is inserted into the cylindrical space 403 of the screw hole insertion portion 401. The screw hole insertion portion 401 is deformed so as to swell in the radially outward direction by the action of the large diameter portion 82 expanding the cylindrical space 403 in the radially outward direction.

  Further, when the attachment members 41, 50, 61 are detached from the mounting main body 20, the fixing member 400 is rotated so that the screw hole insertion portion 401 rotates in a direction away from the screw hole 32 a.

  The fixing structure 3 of the mounting member according to the second embodiment of the present invention attaches the mounting members 41, 50, and 61 by deforming the screw hole insertion portion 401 in a state where the screw hole insertion portion 401 is inserted into the female screw 30. In order to fix to the portion 20, the fixing member 400 is prevented from being inclined and fixed, and the mounting operation member has a large-diameter portion 82 having a circular cross section orthogonal to the axis and a diameter larger than the cylindrical space 403. The fixing member 400 can be fixed by pushing 80 into the cylindrical space 403 and deforming the screw hole insertion portion 401 so that the outer peripheral surface 401a of the screw hole insertion portion 401 follows the inner surface 32aa of the screw hole 32a. The fastening member 400 does not need to be managed like a bolt and a nut, and the fixing member 400 functions as a male screw corresponding to the female screw 30. , It can be simplified with the fixing work of the mounting member 41,50,61 releasably securing the mounting body portion 20 to 50,61.

  In addition, although the fixing structure 3 of the attachment member of this Example 2 illustrated what the cylindrical space 403 penetrates the fixing member 400, it is not restricted to this, The cylindrical space 403 follows the axial direction of the screw hole 32a. Then, it may be formed so as to extend from the rear end surface to a part of the screw hole insertion portion 401. In this case, by pushing a mounting operation member having a larger diameter portion larger than the cylindrical space into the cylindrical space of the screw hole insertion portion 401, the outer peripheral surface of the screw hole insertion portion follows the inner surface of the screw hole. Deform the screw hole insertion part.

  In addition, although fixing structure 1, 2, and 3 of the attachment member which concerns on Example 1 and Example 2 of this invention illustrated what was integrated in the fuse mounting part 10, 100, 300, it is not restricted to this, To an attachment destination Any other member may be used as long as it can removably fix the attachment member formed with the attachment hole used for fixing to the attachment destination. For example, you may use for the fixing structure of the attachment member which uses the interior part of a motor vehicle as an attachment member, and uses an interior panel as an attachment destination.

  Moreover, although the fixing structure 1, 2, and 3 of the attachment member which concern on Example 1 and Example 2 illustrated what has the attachment operation part 80,200, the fixation structure of an attachment member does not have an attachment operation part. It doesn't matter. That is, a tool may be used in place of the attachment operation unit.

  Moreover, although the fixing structure 1, 2, and 3 of the attachment member which concerns on Example 1 and Example 2 illustrated what fixes the some attachment member 41, 50, 61 to an attachment destination, it is not restricted to this, One It is sufficient if two or more attachment members can be fixed to the attachment destination.

  The invention made by the present inventor has been specifically described based on the above-described embodiments of the invention. However, the present invention is not limited to the above-described embodiments of the invention and does not depart from the gist thereof. Various changes can be made.
