Then, they are stacked and stored in a row on the product carry-out mechanism 6. When the product G stored in the product storage rack 5 is sold as a cold product (cold operation mode), the cold air exchanged with the heat exchanger 10 blows out forward from the wind tunnel 12a through the internal fan 9. After the inside of the product storage rack 5 is ventilated through the vent hole of the carry-out shooter 8, the product is circulated and returned to the heat exchanger 10 through the rear duct 13 opened at the back of the inside of the warehouse. The product G stored in the storage rack 5 is kept cold as a cold product at an appropriate sales temperature. When the product G is sold as a hot product (hot operation mode), the heater 11 as a heater is energized instead of the heat exchanger 10 and the warm air heated by the heater 11 is circulated and blown into the cabinet. The product G is heated as a hot product to an appropriate sales temperature. When the product G stored in the product storage rack 5 is cooled or heated to an appropriate sales temperature, it accepts money, and when the product carry-out mechanism 6 is activated based on the operation of the product selection button, It is dropped and carried out downward in order. As is well known, the product G that has been unloaded from the product storage rack 5 and dropped onto the product carry-out shooter 8 slides or rolls on the product carry-out shooter 8 and is sent to the product take-out port 4.

  FIG. 6 shows the product carry-out mechanism 6 and the passage width restricting plate 7 disposed at the lower end outlet of the product storage rack 5. As is well known, this kind of product carry-out mechanism 6 is disposed by assembling a product carry-out mechanism having the same configuration in a back-to-back configuration between the product passages 50 arranged in the front-rear direction. Only the product unloading mechanism 6 is shown. As shown in FIG. 6, the product carry-out mechanism 6 includes a lower pedal 61 that holds the lowest-order product G (also referred to as sales product G1), and a product G that is in the second position from the bottom when the sale product G1 is carried out. And an upper pedal 62 for holding the next sale product G2. The lower pedal 61 is pivotally supported by a base plate 60 that forms the wall of the product passage at the base end, and a protruding position (also referred to as a sales standby position) in which the distal end side protrudes from the substrate 60 to the product passage 50 substantially horizontally. It is movable between a retracted position where it is retracted (immersed in the substrate), and the tip side is spring-biased in a direction protruding to the sales standby position. The base end of the upper pedal 62 is pivotally supported by the substrate 60, and the tip (product locking portion) positioned above the pivot support point protrudes obliquely upward from the substrate 60 to the product passage 50 and the product passage 50. The tip is urged in a direction to return to the retracted position (immerse into the substrate). An electromagnetic solenoid 63 excited by a sales command for a predetermined time width and a link mechanism 64 connected to a plunger of the electromagnetic solenoid 63 are disposed on the back surface of the substrate 60 (the surface opposite to the product passage 50). ing. The plunger of the electromagnetic solenoid 63 and the link mechanism 64 are held in the lowered position (standby for sale) by a return spring (not shown). The rotation stopper 65 is pivotally supported on the base 60 by the base end, and the front end (product engagement portion) is engaged with the deformed groove portion 611 of the lower pedal 61. Is movable between a projecting position (the lower pedal 61 is locked) and a retracted position retracted from the product passage 50 (immersed in the substrate 60), and is attached with a spring in a retracted direction by a coil spring (not shown). It is energized.

  The lower pedal 61 and the upper pedal 62 are driven via the link mechanism 64 by the electromagnetic solenoid 63. As shown in FIG. 6A, in the state where the electromagnetic solenoid 63 is not energized (sales standby state), the lower pedal 61 passes through the rotation stopper 65 protruding into the product passage 50 by the action of the link mechanism 64. The upper pedal 62 is spring-returned to the retracted position immersed in the substrate 60 while being held in the sales standby position and holding the sales product G1. As shown in FIG. 6B, when the electromagnetic solenoid 63 is energized, the link mechanism 64 is raised, and accordingly, the rotation stopper 65 is retracted (immersed into the substrate 60) from the product passage 50. As a result, the lower pedal 61 is unlocked and moved toward the retreat position where it is immersed in the substrate 60 by the load of the sales product G1, and the sales product G1 is unloaded (the load of the sales product G1 is not received). Return to spring. At the same time, that is, when the link mechanism 54 is raised, the upper pedal 62 protrudes from the retracted position immersed in the substrate 60 to the product passage 50 and is locked at the protruding position to lock the next sale product G2. Thereafter, when the electromagnetic solenoid 63 is not energized, the plunger of the electromagnetic solenoid 63 and the link mechanism 64 are restored by the action of the return spring, the lower pedal 61 is locked in the sales standby state, and the upper pedal 62 is returned to the retracted position. Then, the next sale product G2 locked to the upper pedal 62 falls onto the lower pedal 61 and is held.

  The passage width restricting plate 7 that is disposed opposite to the product carry-out mechanism 6 and forms one inner wall of the product passage 50 has a product width (the thickness of the product G in the lying position, the cylindrical container In the case of a can product made of, it plays the role of regulating according to the diameter) and is made of a rectangular flat plate-shaped steel plate. The passage width restricting plate 7 includes engagement shafts 71 and 71 (see FIG. 5) protruding laterally from the upper and lower left and right end portions of the rectangular flat plate-like substrate 70. By being inserted into upper and lower setting grooves 51 a and 51 b formed in the rack side plates 51 and 51, the rack side plates 51 and 51 are supported in an upright posture between the rack side plates 51 and 51. Of the setting grooves 51a and 51b, the upper setting groove 51a is formed in a stepped shape in the front-rear direction (a position away from the position close to the product carry-out mechanism 6), and the lower setting groove 5b is formed in the product passage 50. It is formed in an inverted U-shape inclined in the direction, and extends in the front and rear of the lower setting groove 51b (position close to and away from the product carry-out mechanism 6) and up and down the upper adjustment groove 51a. The front and rear grooves (positions approaching and separating from the product carry-out mechanism 6) are formed so as to be positioned on the vertical line. The passage width restricting plate 7 moves the engagement shafts 71 and 71 forward and backward along the setting grooves 51a and 51b to an advance position (narrow width setting position) and a retreat position (thick width setting position). It is comprised so that a passage width may be set (for example, patent documents 1). The passage width regulating plate 7 is a protruding portion that protrudes toward the product passage 50 at a position that substantially faces the tip (product locking portion) when the upper pedal 62 of the product carry-out mechanism 6 protrudes into the product passage 50. 72 (see FIG. 6), and the upper pedal 62 securely locks the next sale product G2 (for example, Patent Document 2).

  By the way, the passage width restricting plate 7 is configured to hold the product G in cooperation with the lower pedal 61 in the sales standby state, and to hold the product G in cooperation with the upper pedal 62 at the time of selling the product. The product load stacked and stored in the product passage 50 is received. This product load is concentrated and applied to the engagement shafts 71 and 71 in the passage width regulating plate 7 fitted in the setting grooves 51a and 51b. In this case, since the engaging shafts 71 and 71 are integrally formed with the substrate 70 of the passage width restricting plate 7, the thickness of the passage width restricting plate 7 is compensated for to compensate for the mechanical strength of the engaging shafts 71 and 71. Must be thickened. If the plate thickness of the passage width restricting plate 7 is increased, the material cost increases, and it is difficult to integrally form the relatively small engaging shafts 71 and 71 by press working, resulting in an increase in work man-hours. Therefore, in order to reduce the thickness of the passage width restricting plate 7 and prevent the deformation of the engaging shafts 71 and 71 when the plate is thinned, in addition to the passage width restricting plate 7 having the prescribed dimensions having the engaging shafts 71 and 71, In addition, an engagement shaft projecting laterally from the left and right end portions is formed on the additional extension portion that extends in the vertical direction, and then the upper and lower additional extension portions are folded back to form the passage width restricting plate 7 engagement shafts 71 and 71 having a predetermined size. It is known that even if the passage width restricting plate 7 is formed of a thin steel plate, the mechanical strength of the engagement shafts 71 and 71 is compensated (see, for example, Patent Document 3).

Japanese Patent No. 4341940 JP 2003-196728 A JP 2010-108021 A

 According to the product carrying-out device of the vending machine described in Patent Document 3 described above, the passage width regulating plate 7 can be made thinner. However, in order to compensate for the mechanical strength of the engagement shafts 71 and 71 made of thin steel plates, an additional extension portion extending in the vertical direction with respect to the passage width restricting plate 7 having a prescribed size must be provided. There is a problem to be solved in that a material having a dimension longer than that of the width regulating plate 7 is required.

  As a result of various investigations in order to solve the above problems, the present inventor paid attention to the configuration of the protruding portion 72 formed by bending the passage width regulating plate 7. In other words, the protrusion 72 formed by bending the passage width restricting plate 7 projects the upper pedal 62 into the product passage 50 in order to ensure that the next sale product G2 is locked by the upper pedal 62 of the product carry-out mechanism 6. At this time, it is formed at a position substantially opposite to the tip (product locking portion) thereof, and the next sale product G2 is locked together with the product locking portion of the upper pedal 62 protruding into the product passage 50. For this reason, in the passage width restricting plate 7, the next sale product G2 and the product load stacked thereon are applied to the position of the protrusion 72 where the next sale product G2 contacts. In the sales standby state, the sales product G1 is held in contact with the lower pedal 61 projecting into the product passage 50 and the projecting portion 72 of the passage width regulating plate 7 or the vicinity of the projecting portion 72. The sale product G1 and the product load stacked on it are applied to the protrusion 72 where the product G1 abuts or a position in the vicinity thereof. In this way, the product load is applied to the protruding portion 72 formed in the passage width restricting plate 7 or in the vicinity thereof, and the protruding portion 72 is formed to be bent in the passage width restricting plate 7, that is, simply Focusing on the point that the mechanical strength is improved when the bent portion is formed on the flat plate with respect to the flat plate, and if the shaft portion that receives the product load is formed at the protruding portion position of the passage width regulating plate 7, the plate is thinned. Also found that the shaft does not deform.

  Accordingly, the present invention has been made in view of the above points, and its object is to solve the above-mentioned problems, and to reduce the thickness of the passage width restricting plate while increasing the mechanical strength of the engaging shaft only with a material having a prescribed size. An object of the present invention is to provide a product storage device for a vending machine capable of compensation.

  In order to achieve the above object, the invention according to claim 1 is provided with a product carry-out mechanism and a passage width restricting plate that are arranged to face each other with the product passage sandwiched between the lower ends of the product passage formed between the pair of left and right rack side plates. The passage width restricting plate is inserted into the upper and lower setting grooves formed in the rack side plate through the upper and lower engaging shafts protruding laterally from the left and right end portions of the flat plate-like substrate, and the advance position and the product are advanced into the product passage. The product path can be moved forward and backward between the retracted position retracted from the path, supported in an upright position at the advanced position or the retracted position, and substantially opposed to the upper pedal of the product delivery mechanism on the flat substrate. In the product storage device of the vending machine in which the protruding portion protruding toward the side is bent, the passage width restricting plate is connected to the bent portion connecting the flat substrate and the protruding portion. A locking shaft portion that protrudes laterally from the restriction plate and has a vertical plane along the substrate surface as a locking portion is inserted and supported, and the passage width restriction plate advances. The rack side plate is provided with a locking groove having a first blocking portion and a second blocking portion that contact the locking portion of the locking shaft portion and block the backward movement of the passage width regulating plate when moved to the position or the retracted position. It is characterized by being formed.

  According to the vending machine according to claim 1 of the present invention, the product carry-out mechanism and the passage width regulating plate disposed opposite to each other with the product passage sandwiched between the lower ends of the product passage formed between the pair of left and right rack side plates. The passage width regulating plate is inserted into the upper and lower setting grooves formed in the rack side plate with the upper and lower engaging shafts protruding laterally from the left and right end portions thereof, and is advanced from the product passage and retracted from the product passage. A projecting portion that is movable forward and backward between the retracted position, is supported in an upright position at the advanced position or the retracted position, and protrudes toward the product passage at a position substantially opposed to the upper pedal of the product carry-out mechanism. In the product storage device of the vending machine formed by bending, the passage width restricting plate projects sideways from the passage width restricting plate to the bent portion that links the substrate and the protrusion, and the front A locking shaft portion having a vertical plane along the substrate surface as a locking portion is provided, the locking shaft portion is inserted and supported, and when the passage width regulating plate moves to the advanced position or the retracted position, By forming a locking groove having a first blocking portion and a second blocking portion in contact with the locking portion of the locking shaft portion to block the backward movement of the passage width regulating plate, the passage width regulating plate is The received product load is concentrated on the locking shaft. In this case, since the engagement shaft portion is formed continuously with the protrusion provided on the passage width regulating plate, the mechanical strength of the engagement shaft portion is compensated. On the other hand, the product load applied to the upper and lower engaging shafts of the passage width regulating plate is small compared to the locking shaft portion. Therefore, the upper and lower engagement shafts of the passage width restricting plate need only have a guide function to move the passage width restricting plate to a predetermined position by moving along the setting groove. When the passage width restricting plate is thinned In addition, the mechanical strength of the upper and lower engaging shafts is compensated.

It is a side view of the vending machine used as the implementation object of this invention. It is a principal part perspective view of the goods storage apparatus of FIG. 4A and 4B show a product carry-out mechanism and a passage width regulating plate of FIG. 4, in which FIG. 4A is a side view in a sales standby state, and FIG.

  Hereinafter, a product storage device of a vending machine according to an embodiment of the present invention will be described with reference to the accompanying drawings. The merchandise storage device of the vending machine according to the embodiment of the present invention is mainly different from the conventional device in the passage width regulating plate 70, and the entire configuration of the vending machine is the same as that shown in FIG. In addition, since the configuration of the merchandise carry-out mechanism 6 is the same as that shown in FIG. 6, description will be made with reference to FIGS. 4 and 6 as appropriate.

  In FIG. 1, reference numeral 5 denotes a product storage rack, which includes a pair of left and right rack side plates 51, 51, and arc-shaped rack segments 52 are erected on the pair of left and right rack side plates 51, 51 in a vertically connected manner. Yes. A product path 50 (see FIG. 4) meandering in the vertical direction is formed by opposingly arranging the segment rows connecting the rack segments 52 in the vertical direction so as to be shifted by a half pitch back and forth, and a path at the upper end of the product path 50 A top tray 53 is laid by linking the inlet and the front opening (product input port) of the main body cabinet 1, while the product discharge mechanism 6 (see FIG. 4) sandwiching the product passage 50 at the lower end outlet of the product passage 50. The passage width restricting plate 7A is disposed to face the other. The merchandise passage 50 and the merchandise carry-out mechanism 6 are hidden behind the rack side plate 51 in FIG. 1, but the merchandise carry-out mechanism 6 is a merchandise carry-out mechanism having the same configuration between the merchandise paths 50 arranged in the front and rear as is well known. Are assembled and arranged so as to form a pair.

  As shown in FIG. 2, the passage width restricting plate 7A, which is disposed opposite to the product carry-out mechanism 6 and forms one inner wall of the product passage 50, is formed laterally from the upper and lower left and right ends of the rectangular flat plate-like substrate 70. The product passage is provided at a position that includes the projecting engagement shafts 71, 71 and faces the tip (product engagement portion) when the upper pedal 62 (see FIG. 6) of the product delivery mechanism 6 projects into the product passage 50. A protrusion 72 protruding toward 50 is provided, and these points are the same as those of the conventional apparatus shown in FIG. The passage width restricting plate 7A is different from the conventional device in two points: material and structure. First, the point of the first material is that it is made of a steel plate having a rectangular flat plate shape as in the conventional device, but uses a thin steel plate whose plate thickness is thinner than that of the conventional device. Incidentally, the plate width of the passage width regulating plate 7 in the conventional apparatus is 5 mm, whereas a 3 mm thin steel plate is used for the passage width regulating plate 7A of the first embodiment. Next, the point of the second structure is that locking shaft portions 73, 73 projecting sideways from the passage width regulating plate 7 </ b> A are provided so as to continue to the protruding portion 72. The locking shaft portions 73 and 73 will be described later. Further, as shown in FIG. 3, the rack side plate 51 includes upper and lower setting grooves 51a and 51b through which the upper and lower engaging shafts 71 and 71 of the passage width regulating plate 7A are inserted. Are the same. The rack side plates 51 and 51 are different from the conventional apparatus in that a locking groove 51c into which the locking shaft portions 73 and 73 are inserted and supported is additionally provided. The locking groove 51c will also be described later. To do.

  As shown in FIG. 2, the locking shaft portions 73 and 73 of the passage width regulating plate 7 </ b> A are laterally connected to the bent portion 731 linking the flat plate-like substrate 70 and the protruding portion 72. And formed of a locking portion 73A formed of a vertical plane along the plate surface of the substrate 70 and an inclined portion 73B inclined obliquely upward. As described above, the locking shaft portions 73 and 73 include the locking portion 73A formed of a vertical plane along the plate surface of the substrate 70 and the inclined portion 73B inclined obliquely upward with the bent portion 731 interposed therebetween. Thus, the inclined portion 73B has a function as a flange with respect to the locking portion 73A. Accordingly, the mechanical strength of the locking shaft portions 73 and 73 is enhanced even when the substrate 70 is made of a thin steel plate.

  As shown in FIG. 3, the rack side plates 51, 51 are additionally equipped with locking grooves 51c with respect to the locking shaft portions 73, 73 of the passage width regulating plate 7A. The locking groove 51c is formed wider than the upper and lower setting grooves 51a and 51b through which the upper and lower engagement shafts 71 and 71 of the passage width restricting plate 7A are inserted, and the passage width restricting plate 7A is When moved to the advanced position (narrow width setting position) or the retracted position (thick width setting position), the locking shaft portions 73 and 73 are brought into contact with the locking portions 73A to prevent the passage width regulating plate 7A from moving backward. A first blocking unit 51c1 and a second blocking unit 51c2 are provided. The locking grooves 51c are formed wider than the upper and lower setting grooves 51a and 51b because the engaging shafts 71 and 71 are moved forward along the setting grooves 51a and 51b (narrow width setting) by manual operation. Position) and retracted position (thick width setting position) when the passage width is set by moving it forward and backward, the locking shaft portions 73 and 73 abut against the groove edge of the locking groove 51c to obstruct passage width setting. It is intended to prevent it from happening. Further, the first blocking portion 51c1 and the second blocking portion 51c2 of the locking groove 51c are arranged at the front and rear ends of the lower setting groove 51b (positions separated from the position close to the product carry-out mechanism 6), It is formed so that it may be located on the line which connects the groove part of the back and front (position approaching the goods carrying-out mechanism 6 and the position spaced apart) extended up and down of this adjustment groove | channel 51a.

  The passage width restricting plate 7A is engaged with upper and lower setting grooves 51a and 51b in which upper and lower engaging shafts 71 and 71 and an engaging shaft portion 73 are formed in a pair of left and right rack side plates 51 and 51, as in the conventional device. By being inserted into the groove 51c, it is supported in an upright posture between the rack side plates, and the upper and lower engaging shafts 71, 71 are moved along the setting grooves 51a, 51b by manual operation, and the retracted position (thick position). The passage width is set by moving to the width setting position. The passage width regulating plate 7A according to this embodiment is different from the conventional apparatus in that the passage width regulating plate 7A is moved to the advanced position (narrow width setting position) and the retracted position (thick width setting position). In this case, the locking portion 73A of the locking shaft portion 73 is configured to contact the first blocking portion 51c1 and the second blocking portion 51c2 of the locking groove 51c. FIG. 3 shows a state in which the passage width regulating plate 7A has moved to the retracted position (thick width setting position), and the locking portion 73A of the locking shaft portion 73 is in contact with the second blocking portion 51c2 of the locking groove 51c. Yes. When the upper and lower engaging shafts 71, 71 are moved to the advanced position (narrow setting position) along the setting grooves 51a, 51b by manual operation from the state of FIG. 73A contacts the first blocking portion 51c1 of the locking groove 51c.

  As described above, when the passage width regulating plate 7A is moved to the advanced position (narrow width setting position) and the retracted position (thick width setting position), the locking portion 73A of the locking shaft portion 73 is formed in the locking groove 51c. By configuring the first blocking portion 51c1 and the second blocking portion 51c2 to contact each other, the product load applied to the passage width regulating plate 7A is concentrated on the locking shaft portion 73. The reason why the product load is concentrated on the locking shaft 73 is as follows. That is, as shown in FIG. 6, the protrusion 72 formed by bending the passage width regulating plate 7 is an upper pedal for securing the next sale product G <b> 2 by the upper pedal 62 of the product carry-out mechanism 6. When 62 protrudes into the product passage 50, it is formed at a position substantially opposite to the tip (product engagement portion), and the product sale portion G2 is engaged with the product engagement portion of the upper pedal 62 protruding into the product passage 50. Stop. For this reason, in the passage width restricting plate 7, the next sale product G2 and the product load stacked thereon are concentrated on the position of the protrusion 72 where the next sale product G2 contacts. In the sales standby state, the sales product G1 is held in contact with the lower pedal 61 projecting into the product passage 50 and the projecting portion 72 of the passage width regulating plate 7 or the vicinity of the projecting portion 72. The sale product G1 and the product load stacked thereon are concentrated and applied to the protrusion 72 where the product G1 abuts or a position in the vicinity thereof. In this way, since the product load is concentrated and applied to the protruding portion 72 bent in the passage width regulating plate 7 or a position in the vicinity thereof, the locking shaft portion 73 is formed continuously with the protruding portion 72 and the rack side plate. When the first blocking portion 51c1 or the second blocking portion 51c2 of the locking groove 51c formed in the first contact portion 51c2 comes into contact with the locking shaft portion 73, the product load is concentrated.

  Thus, when the product load is concentrated and applied to the locking shaft portion 73, the locking shaft portion 73 according to the present invention is deformed when the rigidity of the locking shaft portion 73 is weak. The flat plate 70 and the protruding portion 72 are formed so as to protrude from the substrate 70 in a side-by-side relationship with the bent portion 731 and the mechanical strength is increased. There is nothing. Since the locking portion 73A of the locking shaft portion 73 is in contact with the first blocking portion 51c1 or the second blocking portion 51c2 of the locking groove 51c, it is responsible for most of the product load applied to the passage width regulating plate 7A. The product load is hardly applied to the upper and lower engagement shafts 71, 71 of the passage width regulating plate 7A. Therefore, the upper and lower engagement shafts 71 and 71 may perform the function of a guide when the passage width restricting plate 7A is set at the advanced position (thin width setting position) and the retracted position (thick width setting position). Even when the plate 7A is made of a thin steel plate, the mechanical strength of the upper and lower engaging shafts 71 and 71 does not become a problem.

  In addition, since the lamination | stacking state of the goods stacked | stacked on the merchandise path 50 is various, it cannot be avoided that a merchandise load is applied to the upper and lower engaging shafts 71 and 71 in the passage width regulation plate 7A. The product load applied to the engagement shafts 71 and 71 is small compared to the product load that the engagement shaft portion 72 is responsible for. Therefore, the mechanical strength of the upper and lower engagement shafts 71 and 71 is compensated even when the passage width regulating plate 7A is formed of a thin steel plate.

  As described above, according to the present invention, the product carry-out mechanism 6 and the passage width regulating plate 7A that are disposed to face each other with the product passage 50 sandwiched between the lower ends of the product passage 50 formed between the pair of left and right rack side plates 51. The passage width restricting plate 7A is inserted into upper and lower setting grooves 51a and 51b formed in the rack side plate 51 with upper and lower engaging shafts 71 and 71 protruding laterally from the left and right ends of the flat substrate 70, respectively. The advancing position can be moved back and forth between the advancing position (thin width setting position) that has advanced into the product passage 50 and the retreating position (thick width setting position) that has been retracted from the product path, and is supported in an upright position at the advancing position or the retreating position. In addition, the product storage device of the vending machine in which a protruding portion 72 protruding toward the product passage 50 is formed at a position substantially opposite to the upper pedal 62 of the product delivery mechanism 6 on the flat board 70. The passage width restricting plate 7A protrudes laterally from the passage width restricting plate 7A so as to be connected to a bent portion 731 that links the flat substrate 70 and the protruding portion 72, and the plate surface of the substrate 70. When the locking shaft portion 73 is inserted and supported, and the passage width restricting plate 7A moves to the advanced position or the retracted position. The rack side plate 51 is formed with a locking groove 51c having a first blocking portion 51c1 and a second blocking portion 51c2 that contact the locking portion 73A of the locking shaft portion 73 and block the backward movement of the passage width regulating plate 7A. As a result, the product load received by the passage width restricting plate 7A is concentrated and applied to the locking shaft portion 73. However, since the locking shaft portion 73 includes the bent portion 731 and the mechanical strength is increased, Depending on the load There is no also be deformed. Thereby, it is possible to make the product load applied to the upper and lower engagement shafts 71, 71 that share and handle the product load applied to the passage width regulating plate 7 </ b> A together with the locking shaft portion 73 small. Therefore, the upper and lower engagement shafts 71 and 71 move only along the setting grooves 51a and 51b, thereby only having a guide function for guiding the passage width regulating plate 7A to a predetermined position (narrow width setting position, thick width setting position). Just have it. Therefore, even when the passage width restricting plate 7A is thinned, the upper and lower engaging shafts 71 and 71 are mechanically formed by forming the locking shaft portion 73 connected to the protrusion 72 provided on the passage width restricting plate 7A. Strength is compensated.

  In the embodiment described above, the locking shaft portion 73 of the passage width regulating plate 7A has been described using the bent portion below the protrusion 72. However, the locking shaft portion 73 uses the bent portion above the protrusion 72. It is also possible. Further, the shape of the locking groove 51c formed in the rack side plates 51, 51 is not limited to the illustrated shape, and the present invention is not limited to the above-described embodiment.
