  Therefore, in the bag of the present invention, the stopper main body can be removed from the lid and replaced.

Specifically, in the bag of the present invention, the stopper main body is configured to be provided with a holder that rotatably holds the operation lever portion and the engaging portion,
The holding member is formed with an insertion hole through which the holder can be inserted, and a locking member capable of locking the holder in a state of being inserted through the insertion hole is disposed on the periphery of the insertion hole. preferable.

  In the bag having the above-described configuration, the holder that rotatably holds the operation lever portion and the engaging portion is formed on the stopper body side, and the holder is inserted into the insertion hole formed in the holding member to be locked. Since the operation lever portion and the engaging portion are configured to be held by the holding member so as to be rotatable with respect to the lid body by being locked by the member, the holding member is held by the holding member. Compared with the case where a mechanism for rotating the operation lever part and the engaging part in the state is provided, the configuration can be simplified.

  Furthermore, in the scissors having the above-described configuration, a protrusion is formed on one of the outer peripheral surface of the holder or the inner peripheral surface of the insertion hole to be positioned when the holder is inserted into the insertion hole, and the outer peripheral surface of the holder or the insertion hole If the concave part into which the protrusion part can be inserted is formed on the other inner peripheral surface, the stopper main body may be mistakenly assembled to the holding member with the decorative part turned upside down or left and right. Can be easily prevented.

  Furthermore, in the bag having the above-described configuration, the locking member can be inserted and removed from the inner peripheral surface of the insertion hole by the operation piece formed on the back surface side of the lid body, and the holder is inserted into the insertion hole. It is preferable that the locking piece portion that can lock the holder is provided by projecting from the inner peripheral surface of the insertion hole so as to be inserted into the recess formed in the holder.

  In the scissors having the above-described configuration, the holder is inserted into the insertion hole in a state where the locking piece portion is pulled into the inner peripheral surface side of the insertion hole, and then the operation piece formed on the back side of the lid is operated. If the locking piece is pulled out from the inner peripheral surface of the insertion hole and inserted into the recess, and the locking piece is locked to the periphery of the recess, the stopper body can be held by the holding member. Conversely, if the operation piece is operated so that the locking piece portion is pulled into the inner peripheral surface side of the insertion hole, the locking state between the locking piece portion and the peripheral edge of the recess can be released, and the holder Can be removed from the holding member. Therefore, the stopper main body can be easily attached to and detached from the holding member.

Furthermore, in the bag having the above-described configuration, a protrusion that protrudes toward the engaged portion is formed on the engaging portion.
In the engaged part, a concave part into which the protruding part can be inserted is arranged,
An engagement protrusion is formed on the outer peripheral surface side at the distal end side of the protrusion,
On the inner peripheral surface side of the concave portion, an engaged protrusion that is engageable with the engaging protrusion and that can be disengaged from the engaging protrusion when the engaging portion is rotated is formed.
The engaging portion and the engaged portion are each configured to have a magnet,
When the magnet engages the engaging protrusion and the engaged protrusion, a magnetic force attracting each other acts, and the operation lever portion rotates in a direction to release the engagement between the engaging protrusion and the engaged protrusion. It is preferable that the engaging portion and the engaged portion are arranged so as to apply a repulsive magnetic force when moving.

  In the bag having the above-described configuration, the engagement protrusion arranged on the stopper main body side is released from the engagement state with the engagement protrusion arranged on the receiving seat portion side by rotating the operation lever portion. At the same time, it receives a repulsive force acting between the magnets arranged on both sides, and is easily separated from the receiving seat side. Further, when engaging the engaging protrusion and the engaged protrusion, if the protruding portion formed on the engaging portion side is inserted into the concave portion formed on the engaged portion side, the stopper The magnets arranged on the main body side are attracted to the magnets arranged on the receiving seat part side and rotated together with the engaging part and the operating lever part, and the magnetic forces generated between the magnets are attracted to each other. Using this, the engaging part and the engaged part are semi-automatically engaged with each other so as to engage the engaging protrusion and the engaged protrusion. Therefore, the scissors having the above-described configuration are configured to engage or disengage the engaging portion and the engaged portion using the magnetic force of the magnets disposed on the stopper main body side and the receiving seat portion side. Therefore, engagement and disengagement between the engaging portion and the engaged portion are easy, and even a small child in an elementary school lower grade can easily operate.

Furthermore, in the scissors having the above-described configuration, the engaging protrusions are formed at two locations that are substantially symmetric with respect to the rotation center of the operation lever portion, and each is a region that is approximately ¼ of the circumference of the protrusion. In addition, in each of the sections along the rotation center axis of the operation lever portion, the outer surface is inclined so as to be expanded toward the base portion side,
Each engaged protrusion is configured such that the inner surface thereof is inclined along the outer surface of each engaging protrusion in the cross section along the rotation center axis of the operation lever portion, and the concave portion is formed by the urging means. It is preferable to adopt a configuration in which the inner peripheral surface of the concave portion is attached to a storage portion formed by being depressed so as to protrude from the inner peripheral surface.

  In the bag having the above-described configuration, the engagement state can be stably maintained by the two pairs of the engagement protrusions and the engagement protrusions disposed at symmetrical positions around the rotation center of the operation lever portion. Further, in the scissors having the above-described configuration, each of the engaged protrusions arranged so as to protrude from the inner peripheral surface of the concave portion is formed by denting the inner peripheral surface of the concave portion via the biasing means. The engagement protrusion is moved so as to be stored in the storage recess when the engagement protrusions are pressed against the urging force of the urging means. be able to. Further, the inner surface of the engaged protrusion is inclined so as to substantially follow the outer surface of each engaging protrusion formed on the engaging portion. Therefore, in the scissors having the above-described configuration, even when the stopper main body is moved closer to the seat portion side with the operation lever portion being in the non-rotating position, the engaged protrusion is used to enter the protrusion into the recess. At the same time, it can be moved so as to be housed in the housing part by being pressed by the engaging protrusion, and when the insertion of the protruding portion into the recessed portion is completed, the engaged protrusion causes the biasing means to move. As it is restored, it returns to protrude from the inner peripheral surface of the recess, and is engaged with each engaging protrusion. That is, in the bag having the above-described configuration, even when the operation lever portion (stopper main body) is arranged at the non-rotating position, the operation lever portion is not rotated, and the engagement portion of the stopper main body is simply moved. The engaging protrusion can be engaged with the engaged protrusion simply by inserting the formed protrusion into the recess formed in the engaged part of the receiving seat. At this time, a magnetic force is generated between the magnets arranged in the engaging portion and the engaged portion so as to attract each other. Therefore, in the scissors having the above-described configuration, if the stopper main body arranged on the front end side of the lid body is brought close to the receiving seat part side arranged on the scissors main body side, the engagement part and the operation lever part will be Even in this state, due to the mutually attracting magnetic force generated between the magnets, the stopper main body moves semi-automatically so that the protrusion is inserted into the recess, and the engagement protrusion and the engagement protrusion Are semi-automatically engaged with each other. As a result, the operability of the stopper main body is further improved.

Furthermore, the bag of the present invention as a school bag,
The main body has a substantially rectangular parallelepiped shape configured by opening the upper part,
The lid is configured such that the lower end when closed is secured to the heel body by a lid stopper,
The receiving seat is arranged at the lower end side portion of the rear wall arranged on the rear side of the bag body,
The stopper main body is preferably arranged on the surface side of the lid so that the decorative portion is exposed.

  If a school bag is made into the said structure, when a school bag is carried on the back at the time of use, a fastener main body will be arrange | positioned in the position which can be visually recognized from a side. That is, the decorative portion can be satisfactorily visually recognized with the school bag on the back during use. Therefore, as in the past, compared to a school bag with a structure in which a stopper body is disposed on the distal end side of the connecting piece extending from the distal end of the lid body and the stopper body is secured to the bottom wall side of the heel body, the design is As a result, the effect of arranging the decorative portion is increased.
