  Next, in the figure, 35 is a guide groove. That is, the hooking portion 33 in the present embodiment has a guide groove 35, and the guide groove 35 has a shape and size in which the fitting projection 29 formed on the lock main body 22 can be inserted. In this case, the fitting projection 29 formed on the lock body 22 is inserted.

  The guide groove 35 will be specifically described. In the present embodiment, the central portion of the hooking portion 33 is recessed on the back surface side to form the operation space 36, and the operation knob 36 is formed at the bottom of the operation space 36. A rectangular hooking hole 37 through which the knob main body 27 is inserted is formed, and the periphery of the operation space 36 is a guide groove 35 into which the fitting projection 29 can be inserted. Therefore, the operation space 36 has an outer dimension such that the fitting projection 29 is positioned around when the knob main body 27 of the operation knob 26 is inserted into the hooking hole 37, whereby the inside of the guide groove 35 is fitted. By fitting the projection 29, the knob body 27 of the operation knob 26 can be inserted into the retaining hole 37.

  Further, an interval is formed between the fixing base 30 and the knob main body 27 such that the periphery of the hooking hole 37 in the hooking portion 33 can be inserted. Then, after the knob main body 27 of the operation knob 26 is inserted into the hook hole 37, the operation knob 26 can be turned. That is, in the present embodiment, by setting the thickness dimension of the decorative plate 25 equal to or smaller than the height dimension of the fixing base 30, the surface of the fixing base 30 is made cosmetic when connecting the decorative plate 25 to the base main body 24. Since the base main body side is not lowered further than the surface of the plate 25, the space between the fixing base 30 and the knob main body 27 and the periphery of the hooking hole 37 in the hooking portion 33 is further formed. Therefore, in a state where the knob main body 27 of the operation knob 26 is inserted into the hooking hole 37, when the operation knob 26 is rotated in the direction perpendicular to the hooking hole 37, the knob main body 27 is above the hooking portion 33. It is supposed to rotate.

  Furthermore, in the present embodiment, the side wall of the operation space 36 is tapered such that the diameter decreases toward the bottom, whereby the operation space 36 has a mortar shape. Therefore, the side wall on the inner peripheral side of the guide groove 35 is also a tapered surface whose diameter decreases as it goes down. Therefore, it is easy to insert the fitting projection 29 into the guide groove 35. That is, when inserting the fitting projection 29 into the guide groove 35, the tapered surface of the fitting projection 29 abuts against the tapered surface in the guide groove 35, and the hooking portion 33 is slipped in that state. By moving to the lock body side, it is possible to easily insert the fitting projection 29 into the guide groove 35.

  Next, the operation of the school bag according to the present embodiment configured as described above will be described. When the cover 20 is fixed to the main body 2 in the school bag according to the present embodiment, the cover 20 is closed and the cover 20 is closed. The fitting projection 29 of the lock main body 22 is inserted into the guide groove 35 while the front end portion of the lock portion 12 reaches the lower portion of the front plate 14 of the pocket portion 12. Then, the knob main body 27 of the operation knob 26 is inserted into the hooking hole 37 of the hooking portion 33. In this state, the operation knob 26 is rotated about 90 degrees, and the longitudinal direction of the knob main body 27 is hooked The direction is orthogonal to the longitudinal direction of the hole 37. This state is a locked state, and a diagram showing the structure of this state is FIG.

  As described above, and as is apparent from FIG. 12, a gap equal to or greater than the thickness dimension of the hooking portion 33 is formed between the fixing base 30 and the knob main body 27. After inserting the retaining hole 37 of the retaining portion 33, when the operation knob 26 is rotated 90 degrees, the knob main body 27 can pass above the retaining portion 33. Therefore, it is possible to securely turn the operation knob 26 and lock it.

  Although the hooking portion is made of metal in this embodiment, when the hooking portion is made of metal in this way, although not shown, as described above, a magnet is incorporated in the base 23 as described above. When the hooking portion 33 is hooked to the operation knob 26, it is preferable that the hooking portion 33 be attracted to the base 23 by a magnetic force so that it can be temporarily locked. By doing so, after inserting the hooking hole 37 of the hooking portion 33 by the knob main body 27 of the operation knob 26 and hooking the hooking portion 33 to the operation knob 26, the operation knob 26 is not rotated 90 degrees. Thus, even when the locking is not completed, the hooking portion 33 is temporarily fixed to the base 24 of the lock main body 23, so that the cover lid 17 can be prevented from moving. At this time, the magnet may be attached to the back surface of the decorative plate 25 in addition to the structure incorporated in the base main body 24. Further, as described above, the hooking portion 33 does not necessarily need to be made of metal and may be a plate made of resin, but even when the hooking portion 33 is made of resin, a magnet is built in the base 23 On the other hand, the hooking portion 33 is provided with a magnetic body, whereby when the hooking portion 33 is hooked on the operation knob 26, the hooking portion 33 is attracted to the base 23 by magnetic force and can be temporarily locked. It is also good.

  Next, when unlocking from the locked state, the operation knob 26 is turned about 90 degrees so that the longitudinal direction of the knob main body 27 and the longitudinal direction of the hooking hole 37 coincide with each other and are orthogonal to each other. This state is an unlocking state, and after this state, the latch main body 27 is removed from the hooking hole 37 while releasing the cover 20 from the main body 2 to release the hooking.

  At this time, in the school bag of the present embodiment, the fitting protrusion is formed on the lock body, and the fitting protrusion is inserted into the retaining portion when the knob body of the operation knob is inserted through the retaining hole. Since the guide groove is formed, when the hooking portion is hooked to the lock body, the knob main body can be inserted into the hooking hole by inserting the fitting projection into the guide groove. It is not necessary to grope the position of the knob body, and it is possible to easily and quickly insert the operation knob into the retaining hole.

  Further, at this time, in the present embodiment, the mutually opposing inner sides of the fitting projections 29 are tapered and the thickness is increased as going downward, whereby the fitting projections are formed by the pair of fitting projections 29. The inner peripheral side of 29 is made to be mortar-shaped, while the operating space 36 in the hooking portion 33 is also made to be mortar-shaped, so that the side wall on the inner peripheral side of the guide groove 35 also becomes smaller as it goes down.
