Description

[Technical Field]

[0001] The present invention relates to a resin molded product and a collar member that is insert-molded into the resin molded product. [Background technology]

[0002] A vehicle has various resin molded parts attached to the vehicle body. For example, a pedal bracket for a pedal device is attached to a dash panel (see Patent Document 1). The pedal bracket is fastened to the dash panel with a bolt. A steel collar member is fitted into a mounting hole in the resin pedal bracket by insert molding. The axial force of the bolt is borne by the steel collar member. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-98439 Summary of the Invention [Problem to be solved by the invention]

[0004] The resin molded product has a plurality of mounting holes. The resin molded product is fixed to the object to be mounted by bolts inserted through the mounting holes. The mounting holes include reference holes that regulate the mounting position of the resin molded product relative to the object to be mounted, and other holes (mounting holes excluding the reference holes) that have larger gaps between them and the bolt shanks than the reference holes. The other holes (mounting holes excluding the reference holes) absorb any dimensional variations in the resin molded product.

[0005] When the mounting holes have different diameters, multiple types of collar members with different diameters are prepared in advance. The type of collar member that matches the mounting hole diameter is selected and then insert-molded. The need to manufacture multiple types of collar members in this way increases the cost of the resin molded product.

[0006] Therefore, an object of the present invention is to provide a resin molded product into which a collar member is inserted by insert molding, which allows for reduced manufacturing costs, and a further object is to provide a collar member that is insert molded into a resin molded product, which allows for reduced manufacturing costs. [Means for solving the problem]

[0007] The resin molded product of the present invention includes a resin main body, a first fixing portion formed on the main body and through which a first bolt for fixing the main body to a workpiece is inserted, a second fixing portion formed on the main body and through which a second bolt for fixing the main body to the workpiece is inserted, and collar members fitted into each of the first fixing portion and the second fixing portion by insert molding. The collar member is formed of a steel wound collar and has a hollow cylindrical body and an entry passage for guiding the injection of resin into the inside of the cylinder during insert molding. The same type of collar member is insert molded into each of the first fixing portion and the second fixing portion, and the first fixing portion has a first mounting hole formed by resin injected into the inside of the cylinder through the entry passage of the collar member, and the second fixing portion has a second mounting hole formed by resin injected into the inside of the cylinder through the entry passage of the collar member. The gap between the first mounting hole and the shank of the first bolt is smaller than the gap between the second mounting hole and the shank of the second bolt, and the first mounting hole is formed as a reference hole. The entry passage of the collar member is formed between both end faces in the winding direction and both end faces in the axial direction of the cylindrical body, Formed between both end faces in the winding direction The passage is formed of a recessed portion located at each end of the passage and a notch formed on at least one of the end faces in the winding direction, and one recessed portion located between the recessed portions. only and a through hole formed on the wall of the cylindrical body. only and a through hole. [Effects of the Invention]

[0009] Even if the same type of collar member is used, the diameters of the first and second mounting holes can be changed as desired. The first mounting hole is formed as a reference hole, and the second mounting hole is formed as another hole (excluding the reference hole) with a larger clearance than the first mounting hole. The first mounting hole, which functions as a reference hole, regulates the mounting position of the resin molded product relative to the object to be mounted, and the second mounting hole absorbs dimensional variations and secures the product to the object to be mounted. Since there is no need to prepare collar members with different hole diameters, the cost of the resin molded product can be reduced. Furthermore, because the collar member is made of a wound collar, a resin entry passage can be easily formed. This also reduces the cost of the resin molded product. The insert-molded collar member is prevented from slipping out in the axial direction by the resin injected into the inside of the cylindrical body through the entry passage.

[0010] Since the collar member is made of a wound collar, a resin entry passage can be easily and inexpensively formed from the passage formed between both end faces in the winding direction and the through hole formed in the wall surface of the cylindrical body.

[0015] Fig. 1 is a front view schematically showing a pedal device 10 for a vehicle, and Fig. 2 is an enlarged front view showing a portion of the main body 20 of the pedal bracket 11 of Fig. 1. Fig. 3A is a cross-sectional view showing the first fixing portion 30 together with the first bolt 31, Fig. 3B is a cross-sectional view showing the second fixing portion 40 together with the second bolt 41, and Fig. 3C is a cross-sectional view showing the third fixing portion 50 together with the third bolt 51. Fig. 4A is a perspective view showing a collar member 60 fitted into each of the first fixing portion 30, the second fixing portion 40, and the third fixing portion 50 by insert molding, and Fig. 4B is a perspective view showing the collar member 60 shown in Fig. 4A with the back side rotated to the front side.

[0016] 1, a pedal device 10 of a vehicle includes a pedal bracket 11 (corresponding to a resin molded product) and an operating pedal 12 rotatably supported by the pedal bracket 11. The operating pedal 12 is, for example, a brake pedal.

[0017] 1 and 2, the pedal bracket 11 generally includes a resin main body 20, a first fixing portion 30 formed on the main body 20, a second fixing portion 40 formed on the main body 20, and a collar member 60 fitted into each of the first fixing portion 30 and the second fixing portion 40 by insert molding. As shown in FIG. 3A, a first bolt 31 is inserted into the first fixing portion 30 to fix the main body 20 to a vehicle body 80 (corresponding to a mounting body). As shown in FIG. 3B, a second bolt 41 is inserted into the second fixing portion 40 to fix the main body 20 to the vehicle body 80. The vehicle body 80 is a dash panel.

[0018] The pedal bracket 11 further has a third fixing portion 50 formed on the main body portion 20, and a collar member 60 fitted into the third fixing portion 50 by insert molding. The illustrated pedal bracket 11 has two third fixing portions 50. As shown in FIG. 3C , a third bolt 51 that fixes the main body portion 20 to the vehicle body 80 is inserted into the third fixing portion 50.

[0019] In this embodiment, the first bolt 31, the second bolt 41, and the third bolt 51 are the same type of bolts having the same outer diameter dimensions of the shanks 32, 42, and 52. However, the first bolt 31, the second bolt 41, and the third bolt 51 may be bolts having different outer diameter dimensions of the shanks 32, 42, and 52.

[0020] 1 and 2, the first fixing portion 30, the second fixing portion 40, and the two third fixing portions 50 are arranged so as to be located at the corners of a substantially rectangle. The first fixing portion 30 and the second fixing portion 40 are arranged diagonally, and the two third fixing portions 50 are arranged diagonally.

[0021] The illustrated pedal bracket 11 has a total of four collar members 60. All four collar members 60 are of the same type. In this specification, "collar members 60 of the same type" means that the collar members 60 have at least the same hole diameter. It is also preferable that the axial lengths of the collar members 60 are also the same.

[0022] 4A and 4B, the collar member 60 is made of a wound steel collar. The collar member 60 has a hollow cylindrical body 61 and an entrance passage 62 that guides the injection of resin into the inside of the cylindrical body 61 during insert molding.

[0023] A winding collar is generally manufactured by a progressive press method that includes multiple press processes while progressively feeding a long steel workpiece. The press processes include a trimming process for trimming the workpiece to the contour shape of the collar member 60, a bending process for bending the workpiece into a cylindrical shape, and a cutting process for cutting the bent cylindrical body 61 from the workpiece.

[0024] As shown in FIG. 4A, the entry passage 62 of the collar member 60 has a passage 65 formed between both end faces 63, 64 in the winding direction, and a through hole 66a composed of cutouts 63a, 64a formed in both end faces 63, 64 in the winding direction. The passage 65 is formed during the bending process of the winding collar. The cutouts 63a, 64a that constitute the through hole 66a are formed during the trimming process of the winding collar. The through hole 66a is formed from cutouts 63a, 64a formed facing each other in both end faces 63, 64, respectively. The cutouts 63a, 64a have a semicircular arc shape. The through hole 66a can be composed of the cutout 63a (or 64a) formed in at least one of the end faces 63, 64 in the winding direction. The shape of the through hole 66a is not limited to a circular shape, and any appropriate shape can be used as long as it can guide the injection of resin into the inside of the cylindrical body 61 during insert molding. For example, the through hole 66a can have a rectangular shape.

[0025] As shown in FIG. 4B, the entrance passage 62 further has a through hole 66b formed in the wall surface of the cylindrical body 61. The contour of the through hole 66b is formed in the trimming process of the winding collar. The through hole 66b is formed in a position facing the through hole 66a. The shape of the through hole 66b is not limited to a circular shape, and any appropriate shape can be adopted as long as it can guide the injection of resin into the inside of the cylindrical body 61 during insert molding. For example, the through hole 66b can have a rectangular shape. The through-hole 66b is The through-hole 66b can be formed at any position on the wall surface of the cylindrical body 61, taking into consideration the flow of resin during insert molding.

[0026] The cylindrical body 61 has recesses 69 formed on both axial end surfaces 67, 68. The recesses 69 are formed when the cylindrical body 61 is separated from the workpiece in the winding collar cutting process. The recesses 69 also function as the entrance passage 62.

[0027] When forming a collar member from a steel pipe, it is necessary to form axial slits or through-holes in the wall surface by machining. In other words, an inlet passage for guiding resin injection must be formed inside the cylindrical body by a separate process from the formation of the cylindrical body of the collar member. In contrast, in this embodiment, the inlet passage 62 (passage 65, through-holes 66a, 66b, and recess 69) is simultaneously formed when the cylindrical body 61 of the collar member 60 is formed by press molding. Therefore, the inlet passage 62 of the collar member 60, which is made of a wound collar, can be easily formed by press molding. This allows the collar member 60 to be manufactured inexpensively, thereby minimizing the increase in cost of the pedal bracket 11 in which the collar member 60 is insert-molded.

[0028] The first fixing portion 30, the second fixing portion 40, and the three third fixing portions 50 each have the same type of collar member 60 insert-molded therein. As shown in FIGS. 1, 2, and 3A, the first fixing portion 30 has a first mounting hole 33 formed by resin injected into the inside of the cylindrical body 61 through the entrance passage 62 of the collar member 60. As shown in FIGS. 1, 2, and 3B, the second fixing portion 40 has a second mounting hole 43 formed by resin injected into the inside of the cylindrical body 61 through the entrance passage 62 of the collar member 60. As shown in FIGS. 1, 2, and 3C, the third fixing portion 50 has a third mounting hole 53 formed by resin injected into the inside of the cylindrical body 61 through the entrance passage 62 of the collar member 60.

[0029] The gap between the first mounting hole 33 and the shank 32 of the first bolt 31 is smaller than the gap between the second mounting hole 43 and the shank 42 of the second bolt 41. The first mounting hole 33 is formed as a reference hole. The mounting position of the pedal bracket 11 relative to the vehicle body 80 is regulated by the first mounting hole 33, which functions as a reference hole. There is a so-called play between the second mounting hole 43 and the shank 42 of the second bolt 41. As a result, the pedal bracket 11 is fixed to the vehicle body 80 with dimensional variations absorbed by the second mounting hole 43.

[0030] As shown in FIGS. 2 and 3A, the first mounting hole 33 has an inner diameter that matches the outer diameter of the shank 32 of the first bolt 31. This allows the first mounting hole 33 to function as a reference hole. As shown in FIG. 2, the second mounting hole 43 is an elongated hole 43a with a major diameter that is larger than the outer diameter of the shank 42 of the second bolt 41. The elongated hole 43a extends in a direction toward the first mounting hole 33. The minor diameter of the elongated hole 43a matches the outer diameter of the shank 42 of the second bolt 41. FIG. 3B shows the second mounting hole 43 aligned along the minor diameter of the elongated hole 43a. The second mounting hole 43 can absorb dimensional variations in the pedal bracket 11 along the extending direction of the elongated hole 43a. In other words, the second mounting hole 43 is formed with a shape that has play in the direction in which dimensional variations in the pedal bracket 11 occur. Since the elongated hole 43a extends in a direction toward the first mounting hole 33, the elongated hole 43a functions to regulate the rotational position of the pedal bracket 11 around the first mounting hole 33.

[0031] In this way, the second mounting hole 43 specifies a direction that can absorb dimensional variations. As a result, the first mounting hole 33 functions as a main reference hole (or a first reference hole), and the second mounting hole 43 functions as a secondary reference hole (or a second reference hole).

[0032] The third mounting hole 53 has an inner diameter that is larger than the outer diameter of the shaft 52 of the third bolt 51 and larger than the gap between the second mounting hole 43 and the shaft 42 of the second bolt 41 (the gap in the minor diameter direction of the elongated hole 43a in this embodiment). The third mounting hole 53 functions as a so-called clearance hole. This allows the third mounting hole 53 to absorb dimensional variations in the pedal bracket 11 when fixing the pedal bracket 11 to the vehicle body 80.

[0033] The first mounting hole 33, the second mounting hole 43, and the third mounting hole 53 are formed by resin injected into the inside of the cylindrical body 61 through the entrance passage 62. The shapes (circular, elongated) and diameters of the first mounting hole 33, the second mounting hole 43, and the third mounting hole 53 can be changed as desired depending on the mold structure used during resin molding. Therefore, it is only necessary to prepare one type of collar member 60 with the same hole diameter.

[0034] As shown in FIG. 3A , the first fixing portion 30 has a first guide surface 34 that guides the first bolt 31 toward the first mounting hole 33. As shown in FIG. 3B , the second fixing portion 40 has a second guide surface 44 that guides the second bolt 41 toward the second mounting hole 43. As shown in FIG. 3C , the third fixing portion 50 has a third guide surface 54 that guides the third bolt 51 toward the third mounting hole 53. The first bolt 31 is guided by the first guide surface 34 to pass through the first mounting hole 33 and is inserted into the first fixing portion 30. Similarly, the second bolt 41 is guided by the second guide surface 44 to pass through the second mounting hole 43 and is inserted into the second fixing portion 40. The third bolt 51 is guided by the third guide surface 54 to pass through the third mounting hole 53 and is inserted into the third fixing portion 50. When fixing the pedal bracket 11 to the vehicle body 80, the first bolt 31, the second bolt 41 and the third bolt 51 can be easily inserted, making the work of attaching the pedal bracket 11 easier.

[0035] 5A and 5B are cross-sectional views that schematically show how the collar member 60 is insert-molded into the first fixing portion 30. FIG.

[0036] As shown in FIG. 5A, the pedal bracket 11 is molded using a first molding die 101 and a second molding die 102 that can be opened and closed relative to each other. When the first molding die 101 and the second molding die 102 are clamped together, a cavity 103 that matches the outer shape of the pedal bracket 11 is formed. The collar member 60 is positioned and set in a predetermined position within the cavity 103. The first molding die 101 has a slide die 104 that is inserted into the cylindrical body 61 of the collar member 60. The slide die 104 is disposed in the first molding die 101 so that it can move forward and backward relative to the collar member 60. The slide die 104 has a tapered pin shape and includes a large-diameter portion 105 located on the base end on the left side of the figure and a reduced-diameter portion 106 whose diameter gradually decreases toward the tip end on the right side of the figure. The large-diameter portion 105 extends to the positions of the through-holes 66a and 66b of the collar member 60. A space of a constant thickness is formed between the outer peripheral surface of the large diameter portion 105 and the inner peripheral surface of the cylindrical body 61. A space whose thickness gradually increases toward the tip is formed between the outer peripheral surface of the reduced diameter portion 106 and the inner peripheral surface of the cylindrical body 61. The reduced diameter portion 106 has an outer shape that forms the first guide surface 34. The tip of the reduced diameter portion 106 has an outer shape that forms the first mounting hole 33.

[0037] When molding the pedal bracket 11, first, the first molding die 101 and the second molding die 102 are opened relatively to each other, and the collar member 60 is set in a predetermined position. The first molding die 101 and the second molding die 102 are then closed, and the slide die 104 is inserted into the cylindrical body 61 of the collar member 60.

[0038] As shown in FIG. 5B , in a clamped state, molten resin is injected into the cavity 103 through a gate (not shown). The molten resin flows through the cavity 103 and reaches the outer periphery of the cylindrical body 61 of the collar member 60. The molten resin is guided through the entry passage 62 (passage 65, through holes 66a, 66b, and recessed portion 69) of the collar member 60 and injected into the inside of the cylindrical body 61. The molten resin is injected into the space between the inner circumferential surface of the cylindrical body 61 and the outer circumferential surface of the slide mold 104. In this way, the first fixing portion 30 is insert-molded into the collar member 60. Furthermore, the first guide surface 34 of the first fixing portion 30 is formed by the reduced diameter portion 106, and the first mounting hole 33 is formed by the tip of the reduced diameter portion 106.

[0039] Similarly, the same type of collar member 60 is insert-molded for the second fixing portion 40 and the third fixing portion 50. Furthermore, the second fixing portion 40 and the third fixing portion 50 have a second guide surface 44 and a third guide surface 54 formed therein, and a second mounting hole 43 and a third mounting hole 53 formed therein.

[0040] After the molten resin has solidified, the slide mold 104 is retracted from the cylindrical body 61 of the collar member 60, and the first molding mold 101 and the second molding mold 102 are relatively opened. The pedal bracket 11 is removed from the mold, and molding is completed.

[0041] The insert-molded collar member 60 is prevented from coming out axially from each of the first fixing portion 30, the second fixing portion 40 and the third fixing portion 50 by the resin that has entered the entry passage 62 (passage 65, through holes 66a, 66b and recess portion 69).

[0042] The first fixing portion 30, the second fixing portion 40, and the third fixing portion 50 are each formed by insert molding with the same type of collar member 60. The first fixing hole 33, the second fixing hole 43, and the third fixing hole 53 are formed by resin injected into the inside of the cylindrical body 61 through the entrance passage 62. Therefore, by changing the external shape of the slide mold 104, the shapes (circular shape, elongated hole shape) and hole diameters of the first fixing hole 33, the second fixing hole 43, and the third fixing hole 53 can be changed as desired. Therefore, it is only necessary to prepare one type of collar member 60 with the same hole diameter, which helps prevent an increase in the cost of the pedal bracket 11.

[0043] As described above, the pedal bracket 11 has a resin main body 20, a first fixing portion 30 formed on the main body 20 and through which a first bolt 31 for fixing the main body 20 to the vehicle body 80 is inserted, a second fixing portion 40 formed on the main body 20 and through which a second bolt 41 for fixing the main body 20 to the vehicle body 80 is inserted, and a collar member 60 fitted by insert molding into each of the first fixing portion 30 and the second fixing portion 40. The collar member 60 is made of a steel wound collar and has a cylindrical body 61 having a hollow cylindrical shape and an entrance passage 62 for guiding the injection of resin into the inside of the cylindrical body 61 during insert molding. The same type of collar member 60 is insert-molded into each of the first and second fixed portions 30 and 40. The first fixed portion 30 has a first mounting hole 33 formed by resin injected into the inside of the cylindrical body 61 through the entry passage 62 of the collar member 60, and the second fixed portion 40 has a second mounting hole 43 formed by resin injected into the inside of the cylindrical body 61 through the entry passage 62 of the collar member 60. The gap between the first mounting hole 33 and the shank 32 of the first bolt 31 is smaller than the gap between the second mounting hole 43 and the shank 42 of the second bolt 41, and the first mounting hole 33 is formed as a reference hole.

[0044] With this configuration, even if the same type of collar member 60 is used, the diameters of the first mounting hole 33 and the second mounting hole 43 can be changed as desired. The first mounting hole 33 is formed as a reference hole, and the second mounting hole 43 is formed as another hole (a mounting hole excluding the reference hole) with a larger amount of play than the first mounting hole 33. The pedal bracket 11 is fixed to the vehicle body 80 with its mounting position determined by the first mounting hole 33, which functions as a reference hole, and dimensional variations are absorbed by the second mounting hole 43. Since there is no need to prepare collar members 60 with different hole diameters, the cost of the pedal bracket 11 can be reduced. Furthermore, because the collar member 60 is formed from a wound collar, the resin entry passage 62 can be easily formed. This also reduces the cost of the pedal bracket 11. The insert-molded collar member 60 is prevented from slipping out in the axial direction by the resin injected into the inside of the cylindrical body 61 through the entry passage 62.

[0045] The first mounting hole 33 has an inner diameter that matches the outer diameter of the shank 32 of the first bolt 31. The second mounting hole 43 is an elongated hole 43a that has a major diameter that is larger than the outer diameter of the shank 42 of the second bolt 41. The elongated hole 43a extends in a direction toward the first mounting hole 33. With this configuration, the first mounting hole 33 functions as a reference hole. The second mounting hole 43 can absorb dimensional variations of the pedal bracket 11 along the extending direction of the elongated hole 43a when fixing the pedal bracket 11 to the vehicle body 80. Because the elongated hole 43a extends in a direction toward the first mounting hole 33, the rotational position of the pedal bracket 11 around the first mounting hole 33 can be regulated.

[0046] The first fixing portion 30 has a first guide surface 34 that guides the first bolt 31 toward the first mounting hole 33, and the second fixing portion 40 has a second guide surface 44 that guides the second bolt 41 toward the second mounting hole 43. With this configuration, the first bolt 31 is guided by the first guide surface 34 to pass through the first mounting hole 33 and is inserted into the first fixing portion 30. Similarly, the second bolt 41 is guided by the second guide surface 44 to pass through the second mounting hole 43 and is inserted into the second fixing portion 40. When fixing the pedal bracket 11 to the vehicle body 80, the first bolt 31 and the second bolt 41 can be easily inserted, facilitating the installation of the pedal bracket 11.

[0047] The pedal bracket 11 further has a third fixing portion 50 formed in the main body 20, through which a third bolt 51 is inserted to fix the main body 20 to the vehicle body 80. A collar member 60 of the same type is insert-molded into the third fixing portion 50, and the third fixing portion 50 has a third mounting hole 53 formed by resin injected into the inside of the cylindrical body 61 through the entry passage 62 of the collar member 60. The third mounting hole 53 has an inner diameter that is larger than the outer diameter of the shank 52 of the third bolt 51 and larger than the gap between the second mounting hole 43 and the shank 42 of the second bolt 41. With this configuration, the third mounting hole 53 can absorb dimensional variations of the pedal bracket 11 when fixing the pedal bracket 11 to the vehicle body 80.

[0048] The third fixing portion 50 has a third guide surface 54 that guides the third bolt 51 toward the third mounting hole 53. With this configuration, the third bolt 51 passes through the third mounting hole 53 while being guided by the third guide surface 54, and is then inserted into the third fixing portion 50. When fixing the pedal bracket 11 to the vehicle body 80, the third bolt 51 can be easily inserted, facilitating the installation work of the pedal bracket 11.

[0049] The entry passage 62 of the collar member 60 has a passage 65 formed between both end faces 63, 64 in the winding direction, and a through hole 66a constituted by a notch 63a (or 64a) formed in at least one of the end faces 63 (or 64) of the end faces 63, 64 in the winding direction. By configuring the collar member 60 in this manner, the resin entry passage 62 can be easily and inexpensively formed from the passage 65 and the through hole 66a in the collar member 60 formed from a winding collar. From this perspective, an increase in the cost of the pedal bracket 11 can also be suppressed.

[0050] The entrance passage 62 further includes a through-hole 66b formed in the wall surface of the cylindrical body 61. By configuring the collar member 60, which is made of a wound collar, the entrance passage 62 for resin can be easily and inexpensively formed from the through-hole 66b. From this perspective, an increase in the cost of the pedal bracket 11 can be suppressed.

[0051] The main body 20 constitutes the main body 20 of the pedal bracket 11 for the pedal device 10 of a vehicle, and the body to which it is attached is the vehicle body 80. By configuring it in this way, it is possible to provide a pedal bracket 11 that keeps costs down.

[0052] In the collar member 60 used in a resin molded product such as the pedal bracket 11 described above, the inlet passage 62 has a passage 65 formed between both end faces 63, 64 in the winding direction, and a through hole 66a constituted by a notch 63a (or 64a) formed in at least one of the end faces 63 (or 64) in the winding direction. By configuring the collar member 60 as a winding collar, the resin inlet passage 62 can be easily and inexpensively formed from the passage 65 and the through hole 66a.

[0053] The entrance passage 62 further has a through hole 66b formed in the wall surface of the cylindrical body 61. By configuring it in this way, the collar member 60 made of a winding collar can easily and inexpensively form the entrance passage 62 for the resin further from the through hole 66b.

[0054] The present invention is not limited to the above-described embodiment and can be modified as appropriate. For example, although the second mounting hole 43 is a linear elongated hole 43a in the above embodiment, the shape of the second mounting hole 43 is not limited to this. Like the third mounting hole 53, the second mounting hole 43 can be formed in a circular shape with an inner diameter larger than the outer diameter of the shank 42 of the second bolt 41. Furthermore, the resin molded product may have a main body 20 that can be fixed in a position slightly rotated around the first mounting hole 33, which serves as a reference hole. In such cases, the second mounting hole 43 can be formed as an elongated hole having an arc shape centered on the first mounting hole 33. It goes without saying that the resin molded product is not limited to the pedal bracket 11. [Explanation of symbols]
