The locking flange portion 36 is inserted and positioned in the space 62.

  In this state, as shown in FIGS. 7 and 15, the operation knob member 46 is positioned in the lateral direction, and the engaging rib 40 (in FIGS. 7 to 10) of the locking flange portion 36 of the mounting pin member 12. And the locking rib 64 of the locking piece 56 of the locking operation member main body 42 are not in contact with each other.

  Further, in this state, the rotation support protrusion 58 of the locking operation member main body 42 is fitted into the rotation support recess 38 of the attachment pin member 12, and the position is shifted during the rotation of the attachment / detachment operation. It is configured so that there is nothing.

  Then, from this state, the operation knob member 46 is grasped with a finger or the like, and the locking operation member 14 is rotated in the direction of arrow A (in the attachment direction) in FIGS. In this case, when the locking operation member 14 is rotated on the back side of the opening 60, a space 62 is formed in which the locking flange portion 36 of the mounting pin member 12 can rotate, so that rotation is possible. Yes.

As the locking operation member 14 rotates, as shown in FIG. 8, the locking piece 56 of the locking operation member main body 42 and the locking flange portion 36 of the mounting pin member 12 start to engage with each other.
At this time, the locking flange portion 36 of the mounting pin member 12 and the locking piece 56 of the locking operation member main body 42 are connected to the locking rib 64 of the locking piece 56 of the locking operation member main body 42 and the mounting pin member. The engagement ribs 40 of the twelve engagement flange portions 36 make contact not by surface contact but by line contact, so that the engagement operation member 14 can be easily rotated and the attachment operation becomes smooth.

  Then, as shown in FIG. 9, by further rotating the locking operation member 14 in the direction of the arrow, the locking rib 64 of the locking piece 56 of the locking operation member main body 42 is engaged with the engaging pin member 12. It will be in the position which got over the engagement rib 40 of the stop flange part 36, and will be in the attachment completion position as shown in FIG. 10, FIG.

  When the removal operation is performed from such an attachment completion position, the operation knob member 46 is grasped with a finger or the like, and the locking operation member 14 is attached in the above attachment direction as shown in FIGS. What is necessary is just to rotate to the direction opposite to A, the arrow B direction (in the removal direction). Accordingly, the rear end 64a of the locking rib 56 of the locking piece 56 of the locking operation member main body 42 in the mounting rotation direction and the engaging rib 40 of the locking flange portion 36 of the mounting pin member 12 are locked. It is cancelled | released and the latching operation member 14 can be removed by operation opposite to said attachment. Since the operation is basically the reverse of the above mounting operation, detailed description thereof is omitted.

  Although the engagement rib 64 of the engagement piece 56 of the engagement operation member main body 42 and the engagement rib 40 of the engagement flange portion 36 of the mounting pin member 12 are not shown in the figure, their mutual engagement / release is possible. The corners and the like are rounded so as to be easy.

  In the above embodiment, the rotation support protrusion 58 of the locking operation member main body 42 is fitted in the rotation support recess 38 of the attachment pin member 12. It is also possible to provide a rotation support protrusion on the member 12 and to provide a rotation support recess in the locking operation member main body 42.

  Further, although the shape of the locking flange portion 36 of the mounting pin member 12 is substantially oblong to match the shapes of the locking component mounting hole 20 and the locked hole 24 of the locked member, It is only necessary to match the shapes of the component mounting hole 20 and the locked hole 24 of the locked member, and although not shown, for example, a circular shape, a triangular shape, a rectangular shape, a propeller shape, and the like can be appropriately changed.

  Furthermore, in the said Example, although the attachment pin member 12 was attached to the splash prevention board 22 of the partition plate 21 which is a to-be-latched member, the latching operation member 14 was attached to the wall part 18 of the container 16 which is a latching component. On the contrary, it is of course possible to attach the mounting pin member 12 to the wall portion 18 of the container 16 that is a locking part, and to attach the locking operation member 14 to the jumping prevention plate 22 of the partition plate 21 that is a locked member. It is.
