Description

[Technical field]

[0001] The present invention relates to a cover body. [Background technology]

[0002] A cover body that protects an object by covering at least a part of the object may be formed from a multi-color molded body. For example, an outer cover of a vehicle lamp as a cover body may constitute a part of the vehicle's appearance, and in this case, design tends to be important. The following Patent Document 1 discloses an outer cover of a vehicle lamp that is made of a multi-color molded body and constitutes a part of the vehicle's appearance.

[0003] The outer cover of the vehicle lamp in the following Patent Document 1 is a two-color molded body consisting of a first resin part which is a primary molded body and a second resin part which is a secondary molded body, and the second resin part covers the entire outer surface of the first resin part. For this reason, Patent Document 1 claims that the outer cover of this vehicle lamp can cover gate marks formed on the outer surface of the first resin part with the second resin part to make them invisible, thereby improving the design. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2011-187299 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when the gate mark is covered by another resin part, as in the outer cover of the vehicle lamp of Patent Document 1, a sink mark may occur on the surface opposite to the resin part where the gate mark is formed in the part of the other resin part that covers the gate mark and its surroundings. In the outer cover of the vehicle lamp of Patent Document 1, the second resin part that covers the gate mark of the first resin part is located outside the first resin part, and the surface of the second resin part where the sink mark occurs is exposed to the outside. For this reason, there is a concern that the sink mark will degrade the design.

[0006] Therefore, an object of the present invention is to provide a cover body capable of suppressing deterioration in design. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the cover body of the present invention comprises a multi-color molded body including a first resin part having a gate mark on its outer surface, and a second resin part of a different color from the first resin part, adhered to the outer surface of the first resin part and covering the gate mark, and is characterized in that the outer surface of the second resin part has a step portion that overlaps with the gate mark.

[0008] In this cover body, even if a sink mark occurs on the outer surface of the portion of the second resin part covering the gate mark of the first resin part and its surroundings, the sink mark and the above-mentioned step part can be overlapped. Therefore, according to this cover body, the step part can make the sink mark less noticeable, and deterioration of the design can be suppressed. Note that the color in this specification also includes colorless and transparent.

[0009] The gate mark may be a concave depression.

[0010] In this case, the height of the step portion may be smaller than the depth of the gate mark.

[0011] The step portion may cross the gate mark.

[0012] With this configuration, the step portion appearing on the outer surface of the second resin portion can cross the sink mark, making the sink mark less noticeable than when the step portion is located only in the region where the sink mark is formed.

[0013] The step portion may overlap the center of the gate mark.

[0014] The center of the sink mark tends to be located directly above the center of the gate mark, so by using this configuration, the step portion can be made to overlap with the center of the sink mark, making the sink mark less noticeable than when the step portion and the center of the gate mark do not overlap.

[0015] Further, the cover body may have a character drawn thereon, positioned closer to the second resin portion than the first resin portion, that is visible from the outside and overlaps with the gate mark.

[0016] According to this configuration, the character and the sink mark can be overlapped, and the sink mark can be made less noticeable by the character. Note that the character means a figure, a symbol, a letter, and the like.

[0017] In this case, at least a part of the character may be depicted by the stepped portion.

[0018] The step portion may be formed by an inclined surface that is inclined with respect to the outer surface of the first resin portion and crosses the gate mark, and the inclined surface may overlap with the center of the gate mark.

[0019] In this case, an edge on one side in the inclination direction of the inclined surface may overlap the center of the gate mark.

[0020] The outer surface of the second resin part bends at the edge of the inclined surface, and therefore, with this configuration, the bent portion of the outer surface of the second resin part can be made to overlap with the center of the sink mark, making the sink mark less noticeable compared to a case where the bent portion does not overlap with the center of the sink mark.

[0021] In this case, the edge on the one side may be closer to the first resin portion than the edge on the other side in the inclination direction of the inclined surface.

[0022] With this configuration, the thickness of the second resin portion above the center of the gate mark can be made thinner than when the edge on one side is farther from the first resin portion than the edge on the other side, making the sink smaller and less noticeable than in the above case. Effect of the Invention

[0023] As described above, according to the present invention, a cover body capable of suppressing deterioration in design is provided. [Brief description of the drawings]

[0025] Hereinafter, embodiments for carrying out the cover body according to the present invention will be illustrated with reference to the accompanying drawings. The embodiments illustrated below are intended to facilitate understanding of the present invention, and are not intended to limit the present invention. The present invention can be modified or improved from the following embodiments without departing from the spirit of the present invention. In addition, in the above-mentioned accompanying drawings, the dimensions of each member may be exaggerated in order to facilitate understanding.

[0026] Fig. 1 is a front view showing a vehicle lamp equipped with a cover body according to an embodiment of the present invention. Fig. 2 is a cross-sectional view showing the vehicle lamp taken along line II-II in Fig. 1. The vehicle lamp 100 according to this embodiment is a marker lamp for an automobile, and more specifically, is a rear combination lamp that integrates a tail lamp, a stop lamp, and a back lamp.

[0027] As shown in Figs. 1 and 2, the vehicle lamp 100 of this embodiment has a generally symmetrical configuration, and mainly includes a housing 70, a first light source 81, two second light sources 82, a first reflector 85, and a second reflector 86. The housing 70 mainly includes an outer cover 1 as a cover body and a lamp housing 71. The lamp housing 71 is configured in a box shape having one opening, and the outer cover 1 is fixed to the lamp housing 71 so as to close the opening. The space formed by the lamp housing 71 and the outer cover 1 is a lamp chamber 70R, and the first light source 81, the two second light sources 82, the first reflector 85, and the second reflector 86 are accommodated in this lamp chamber 70R.

[0028] The outer cover 1 as the cover body of this embodiment includes a multicolor molded body 2 and a sticker 3 attached to the multicolor molded body 2. In this embodiment, the shape of the multicolor molded body 2 is a plate-like shape that extends vertically and horizontally and is elongated in the left-right direction, and the thickness of the multicolor molded body 2 is generally uniform. The multicolor molded body 2 includes a first resin part 10, a second resin part 20, and a third resin part 30 that are different in color from each other, the first resin part 10 and the third resin part 30 being primary molded bodies, and the second resin part 20 being secondary molded bodies. The first resin part 10 and the third resin part 30 have light transmittance, the first resin part 10 is red, and the second resin part 20 is colorless and transparent. The color of the second resin part 20 is black, and the light transmittance of the second resin part 20 is lower than that of the first resin part 10. Examples of materials for the first resin part 10, the second resin part 20, and the third resin part 30 include acrylic resin.

[0029] 3 is a front view showing the first resin part 10 and the third resin part 30, which are primary molded bodies, as viewed from the outside. As shown in FIGS. 2 and 3, the first resin part 10 of this embodiment is composed of a plate-like main part 11 that extends vertically and horizontally and is elongated in the left-right direction, an upper flange part 12 that connects to an upper edge part of the main part 11, and a lower flange part 13 that connects to a lower edge part of the main part 11. The inner surface of the upper flange part 12 and the inner surface of the lower flange part 13 are connected to the inner surface of the main part 11, and these surfaces form an inner surface 10S2, which is the back surface of the first resin part 10. The thickness of the upper flange portion 12 and the lower flange portion 13 is thinner than that of the main portion 11, and a step portion is formed between the main portion 11 and the upper flange portion 12 and between the main portion 11 and the lower flange portion 13 on the outer surface 10S2, which is the surface of the first resin portion 10. The thickness of the upper flange portion 12 and the lower flange portion 13 is, for example, about 1.8 mm to 2.6 mm, and the thickness of the main portion is, for example, about 2.6 mm to 3.2 mm. Five gate marks 15a to 15e are formed on the outer surface of the upper flange portion 12, which is a part of the outer surface 10S1 of the first resin portion 10, and these gate marks 15a to 15e are arranged at intervals in the left-right direction. In addition, two gate marks 15f to 15g are formed at intervals in the left-right direction on the outer surface of the lower flange portion 13, which is another part of the surface 10S1. These seven gate marks 15a to 15g are concave depressions, and are generally the same in shape, with an outer edge that is generally circular and a surface that is generally the same as a part of a sphere. The depth of the gate marks is, for example, about 0.7 mm to 0.8 mm. The shape of the gate marks 15a to 15g is not particularly limited, and may be, for example, a cone-shaped depression.

[0030] The third resin part 30 of this embodiment is composed of a right resin part 30R and a left resin part 30L. The right resin part 30R and the left resin part 30L are disposed at positions generally symmetrical to each other in the left-right direction, and the shapes of the right resin part 30R and the left resin part 30L are generally symmetrical to each other in the left-right direction. For this reason, the left resin part 30L will be described, and a description of the right resin part 30R will be omitted. The left resin part 30L is disposed below the first resin part 10 and to the left of the center of the first resin part 10 in the left-right direction. The left resin part 30L is composed of a plate-shaped main part 31 that extends up, down, left and right and is elongated in the left-right direction, and a flange part 32 that is connected to an edge part of the main part 31. The flange part 32 extends continuously over the upper edge part, the right edge part, and the lower edge part of the main part 31. The inner surface of the flange portion 32 is connected to the inner surface of the main portion 31, and these surfaces form an inner surface 30S2 which is the back surface of the third resin portion 30. The thickness of the flange portion 32 is thinner than that of the main portion 31, and a step portion is formed between the main portion 31 and the flange portion 32 on an outer surface 30S1 which is the front surface of the third resin portion 30. The thickness of the main portion 31 is, for example, the same as the thickness of the main portion 11 of the first resin portion 10, and the thickness of the flange portion 32 is, for example, the same as the thickness of the upper flange portion 12 of the first resin portion 10.

[0031] FIG. 4 is a front view showing the second resin part 20, which is a secondary molded body, from the outside. In FIG. 4, the first resin part 10 and the third resin part 30 are shown by dashed lines. As shown in FIG. 2 and FIG. 4, the second resin part 20 of this embodiment is composed of an upper resin part 20U that is a plate-like part extending vertically and horizontally and is elongated in the horizontal direction, and a lower resin part 20D that is arranged below the upper resin part 20U and is a plate-like part extending vertically and horizontally and is elongated in the horizontal direction. The upper resin part 20U covers the entire upper flange part 12 of the first resin part 10 from the outside, and is bonded to the surface of the outer side of the upper flange part 12. Therefore, five gate marks 15a to 15e on the surface of the outer side of the upper flange part 12 are covered by the upper resin part 20U. The lower edge of the upper resin part 20U is connected to the entire upper edge of the main part 11 of the first resin part 10, and the outer surface of the upper resin part 20U is connected to the outer surface of the main part 11. The lower resin part 20D covers the entire lower flange part 13 and the entire flange part 32 from the outer side, and is bonded to the outer surfaces of the lower flange part 13 and the flange part 32. Therefore, two gate marks 15f to 15g on the outer surface of the lower flange part 13 are covered by the upper resin part 20U. In addition, the gap between the first resin part 10 and the third resin part 30 in the up-down direction is filled by the lower resin part 20D, and the first resin part 10 and the third resin part 30 are connected by the lower resin part 20D, and the first resin part 10, the second resin part 20, and the third resin part 30 are integrated. A part of the outer peripheral edge of the lower resin part 20D is connected to the entire lower edge of the main part 11, and the outer surface of the lower resin part 20D is connected to the outer surface of the main part 11. Another part of the outer peripheral edge of the lower resin part 20D is connected to the entire upper edge, right edge, and lower edge of the main part 31 in the left resin part 30L, and to the entire upper edge, left edge, and lower edge of the main part 31 in the right resin part 30R. The outer surface of the lower resin part 20D is connected to the outer surfaces of the main part 31 in the left resin part 30L and the right resin part 30R.Such a second resin portion 20 does not cover the main portion 11 of the first resin portion 10 and the main portions 31 in the right resin portion 30R and the left resin portion 30L, and the second resin portion 20 and these main portions 11, 31 are exposed to the outside.

[0032] FIG. 5 is an enlarged cross-sectional view showing the vicinity of the gate mark 15a in FIG. 2. As shown in FIGS. 4 and 5, the outer surface of the upper resin part 20U has a step portion 25. In this embodiment, the step portion 25 extends linearly from the right edge to the left edge of the surface. The step portion 25 is formed by an inclined surface 26. The inclined surface 26 is inclined upwardly with respect to the outer surface of the upper flange portion 12, which is a part of the outer surface 10S1 of the first resin part 10, so as to approach the upper flange portion 12. Therefore, the thickness of the upper resin part 20U above the step portion 25 is thinner than that below the step portion 25. Such a step portion 25 overlaps with five gate marks 15a to 15e when the outer surface of the upper resin part 20U is viewed from the front as shown in FIG. 4. Also, the width 25w of the step portion 25 in the inclination direction of the inclined surface 26 in this case is smaller than the maximum width of each of the gate marks 15a to 15e with which the step portion 25 overlaps, and is, for example, 0.5 mm or less. Such a step portion 25 crosses each of the gate marks 15a to 15e. Also, the step portion 25 overlaps with the center C of each of the gate marks 15a to 15e. More specifically, an edge 26e1 on one side in the inclination direction of the inclined surface 26 overlaps with the center C of the gate marks 15a to 15e. This edge 26e1 on one side is closer to the first resin portion 10 than an edge 26e2 on the other side in the inclination direction of the inclined surface 26. Also, the height 25h of the step portion 25 is smaller than the depth 15D of the gate marks 15a to 15e, and is, for example, about 0.1 mm to 0.3 mm. Height 25h of step 25 is the height in a direction perpendicular to the outer surface of upper flange 12 in the vicinity of step 25. Height 25h of step 25 may be equal to or greater than depth 15D of gate marks 15a to 15e.

[0033] Next, a method for producing the multicolor molded body 2 in the outer cover 1 of this embodiment will be described.

[0034] FIG. 6 is a cross-sectional view showing an outline of an example of a state in which the first resin part 10 and the third resin part 30, which are primary molded bodies, are molded, and is a cross section passing through a gate forming a gate mark 15a. As shown in FIG. 6, the first resin part 10 and the third resin part 30 are formed using a fixed first mold 41 and a second mold 42 movable relative to the first mold 41. In a state in which the second mold 42 is pressed against the first mold 41 to bring the first mold 41 and the second mold 42 together, a space 51 corresponding to the first resin part 10 and a space 53 corresponding to the third resin part 30 are formed between the first mold 41 and the second mold 42. Seven direct gates 45 are formed in the second mold 42 at positions corresponding to the first resin part 10. In addition, side gates are formed in the second mold 42 at positions corresponding to the right resin part 30R and the left resin part 30L of the third resin part 30, respectively. In FIG. 3, the positions corresponding to these side gates are indicated by arrow A, and in FIG. 6, the side gate 46 corresponding to the left resin portion 30L is indicated by a broken line. In this manner, when the first mold 41 and the second mold 42 are mated, the molten resin that will become the first resin portion 10 is injected from the direct gate 45 into the space 51 to fill the space 51. Then, the tip of a gate pin (not shown) closes the direct gate 45 to hold the filled molten resin under pressure. In addition, the molten resin that will become the third resin portion 30 is injected from the side gate 46 into the space 53 to fill the space 53, and the filled molten resin is held under pressure. In this manner, the molten resin filled in each of the spaces 51 and 53 is cooled and solidified, thereby forming the first resin portion 10 and the third resin portion 30, which are primary molded bodies. At this time, the above-mentioned gate marks 15a to 15g are formed in the first resin portion 10 due to the tip of the gate pin blocking the direct gate 45, and the shape of the gate marks 15a to 15g generally corresponds to the shape of this tip. The position of the gate for injecting the molten resin to become the first resin portion 10 into the space 51 and the position of the gate for injecting the molten resin to become the third resin portion 30 into the space 53 are not particularly limited. Next, the second mold 42 is replaced with a third mold to mold the second resin portion 20, which is a secondary molded body.

[0035] FIG. 7 is a cross-sectional view showing an example of a state in which the second resin part 20 is molded, and is a cross-sectional view at the same position as FIG. 6. As shown in FIG. 7, when the third mold 43 is pressed against the first mold 41 and the first mold 41 and the third mold 43 are mated, a space 52 corresponding to the second resin part 20 is formed between the first mold 41 and the third mold 43. A plurality of side gates 47 are formed in the third mold 43 at positions corresponding to the second resin part 20. Note that in FIG. 4, the positions corresponding to these side gates 47 are indicated by arrows B. In this manner, when the first mold 41 and the third mold 43 are mated, the molten resin that will become the second resin part 20 is injected from the side gate 47 into the space 52 to fill the space 52, and the filled molten resin is kept under pressure. The molten resin filled in the space 52 is cooled and solidified, thereby forming the second resin part 20, which is a secondary molded body, and the multicolor molded body 2 is manufactured. The position of the gate through which the molten resin to become the second resin portion 20 is injected into the space 52 is not particularly limited.

[0036] Next, returning to FIG. 1, the seal 3 will be described. The seal 3 of this embodiment is attached to the outer surface of the upper resin part 20U, which is a part of the outer surface 20S1 of the second resin part 20 in the multi-color molded body 2. A plurality of characters are drawn on the seal 3. The seal 3 draws characters on the outer cover 1 that are located on the second resin part 20 side from the first resin part 10 and are visible from the outside. The characters of this embodiment are the white letters "A", "B" and "C", and "B" overlaps with the gate mark 15c. The characters may be figures, symbols, letters, etc., and the number and color of the characters are not particularly limited. As the seal 3, for example, a laminate having a colorless and transparent base layer, a printing layer formed on one side of the writing layer, and a colorless and transparent adhesive layer formed on the other side of the base layer can be mentioned, and the characters are drawn by the printing layer.

[0037] The first light source 81 shown in FIG. 1 and FIG. 2 emits light as a tail lamp or a stop lamp. In this embodiment, the first light source 81 is a so-called LED array in which a plurality of LEDs (Light Emitting Diodes) are arranged in the left-right direction, and each LED emits white light. The first light source 81 is disposed to face the main part 11 in the first resin part 10, and the light emitted from the first light source 81 passes through the main part 11 and is emitted to the outside. Since the first resin part 10 is red, the light of the red component of the light emitted from the first light source 81 is emitted to the outside. In addition, the periphery of the first light source 81 is surrounded by a first reflector 85 so that the light emitted from the first light source 81 is effectively incident on the main part 11. In addition, the first reflector 85 prevents the light emitted from the first light source 81 from being incident on the main part 31 in the third resin part 30.

[0038] The two second light sources 82 emit light as a back lamp. In this embodiment, the second light source 82 is a so-called LED array in which a plurality of LEDs are arranged in the left-right direction, and each LED emits white light. One of the second light sources 82 is arranged to face the main part 31 in the right resin part 30R of the third resin part 30, and the other second light source 82 is arranged to face the main part 31 in the left resin part 30L. The light emitted from each of the second light sources 82 passes through the main part 31 and is emitted to the outside. Since the third resin part 30 is colorless, the white light emitted from the first light source 81 is emitted to the outside. In addition, the periphery of each of the second light sources 82 is surrounded by a second reflector 86 so that the light emitted from the second light source 82 is effectively incident on the main part 31. In addition, the second reflector 86 prevents the light emitted from the second light source 82 from being incident on the main part 11 in the first resin part.

[0039] As described above, the outer cover 1 as the cover body in this embodiment includes the multicolor molded body 2. The multicolor molded body 2 includes the first resin part 10 having the gate marks 15a to 15g on the outer surface 10S1, and the second resin part 20, which is a different color from the first resin part 10 and is bonded to the outer surface 10S1 of the first resin part 10 to cover the gate marks 15a to 15g. The outer surface 20S1 of the second resin part 20 has a step part 25 that overlaps with the gate marks 15a to 15e. Therefore, even if a sink occurs on the outer surface 20S1 of the second resin part 20 in a portion covering the gate marks 15a to 15e of the first resin part 10 and its surroundings, the sink and the step part 25 can be overlapped. Therefore, according to the outer cover 1 of this embodiment, the step part 25 can make the sink less noticeable, and deterioration of the design can be suppressed.

[0040] Furthermore, in the outer cover 1 of this embodiment, the step portion 25 crosses the gate marks 15a to 15e. Therefore, according to the outer cover 1 of this embodiment, the step portion 25 appearing on the outer surface 20S1 of the second resin portion 20 can cross the sink mark, making the sink mark less noticeable than when the step portion 25 is located within the region where the sink mark is formed.

[0041] Furthermore, in the outer cover 1 of this embodiment, the step portion 25 overlaps with the center C of each of the gate marks 15a to 15e. The center of the sink marks tends to be located directly above the center of the gate marks. Therefore, according to the outer cover 1 of this embodiment, the step portion 25 can overlap with the center of the sink marks, and the sink marks can be made less noticeable compared to a case where the step portion 25 does not overlap with the center C of each of the gate marks 15a to 15e.

[0042] Furthermore, on the outer cover 1 of this embodiment, a character, the letter "B," is drawn which is located closer to the second resin part 20 than the first resin part 10, is visible from the outside, and overlaps with the gate mark 15c. Therefore, the character, the letter "B," can overlap with the sink mark, and the character, the letter "B," can make the sink mark less noticeable.

[0043] In the outer cover 1 of this embodiment, the step portion 25 is formed by an inclined surface 26 that is inclined with respect to the outer surface of the upper flange portion 12, which is a part of the outer surface 10S1 of the first resin portion 10, and crosses each of the gate marks 15a to 15e. Furthermore, an edge 26e1 on one side in the inclination direction of the inclined surface 26 overlaps with the center C of the gate marks 15a to 15e. The outer surface 20S1 of the second resin portion 20 is bent at the edge of the inclined surface 26. According to the outer cover 1 of this embodiment, the bent portion on the outer surface 20S1 of the second resin portion 20 can be made to overlap with the center of the sink mark, and the sink mark can be made less noticeable compared to a case where the bent portion does not overlap with the center of the sink mark. The inclined surface 26 does not have to overlap with the center C of the gate marks 15a to 15e. However, from the viewpoint of making the sink marks less noticeable, it is preferable that the inclined surface 26 and the center C of the gate marks 15a-15e overlap, and it is more preferable that the edge 26e1 on one side of the inclined surface 26 overlaps with the center C of the gate marks 15a-15e. Furthermore, in the outer cover 1 of this embodiment, the inclination angle of the inclined surface 26 with respect to the outer surface of the upper flange portion 12 is an acute angle. Therefore, according to the outer cover 1 of this embodiment, burrs can be less likely to occur on the edges on both sides in the inclination direction of the inclined surface 26, compared to when the inclination angle of the inclined surface 26 is approximately 90 degrees.

[0044] In the outer cover 1 of this embodiment, the edge 26e1 on one side is closer to the first resin part 10 than the edge 26e2 on the other side in the inclination direction of the inclined surface 26. Therefore, the thickness of the second resin part 20 on the center C of each of the gate marks 15a to 15e can be made thinner than when the edge 26e1 on one side is farther from the first resin part 10 than the edge 26e2 on the other side. Therefore, according to the outer cover 1 of this embodiment, the sink mark can be made smaller than in the above case, and the sink mark can be made less noticeable. Note that the edge 26e1 on one side may be farther from the first resin part 10 than the edge 26e2 on the other side. Even in such a case, the bent portion on the outer surface 20S1 of the second resin part 20 can be made to overlap with the center of the sink mark, and the sink mark can be made less noticeable than when the bent portion does not overlap with the center of the sink mark.

[0045] Although the present invention has been described above using the above-mentioned embodiments as examples, the present invention is not limited to these.

[0046] For example, in the above embodiment, the multicolor molded body 2 including the first resin part 10, the second resin part 20, and the third resin part 30, which are different from each other in color, has been described as an example. However, the multicolor molded body 2 may include the first resin part 10 and the second resin part 20, which are different from each other in color, and for example, the multicolor molded body 2 may not include the third resin part 30. In addition, the color of the resin part including the first resin part 10 and the second resin part 20 is not particularly limited. For example, in the above embodiment, the third resin part 30 may be orange having translucency, and the two second light sources 82 may be configured to emit light as turn lamps. In this way, the vehicle lamp 100 can be a rear combination lamp in which the tail and stop lamps and the turn lamps are integrated. In this way, the vehicle lamp in which the outer cover 1 is used is not particularly limited.

[0047] In the above embodiment, the outer cover 1 used in the vehicle lamp 100 has been described as an example of the cover body. However, the cover body is not particularly limited. For example, the cover body may be a part of a housing that houses a sensor such as a millimeter wave radar or a lidar. In this case, the multi-color molded body in the cover body may be made of multiple resin parts with low light transmittance, and may be configured so that the inside cannot be seen from the outside.

[0048] In the above embodiment, the first resin portion 10 has seven gate marks 15a to 15g on the outer surface 10S1. However, the number of gate marks is not particularly limited, and may be, for example, one.

[0049] In the above embodiment, the step portion 25 extending linearly and crossing the five gate marks 15a to 15e has been described as an example. However, the step portion 25 only needs to overlap the gate marks, and the number of gate marks that the step portion 25 overlaps is not particularly limited. For example, the step portion 25 may extend in a curved line and cross a plurality of gate marks. Also, the entire step portion 25 may overlap a part of one gate mark, and an example of such a step portion 25 may be one formed by a groove. Also, the number of step portions 25 that the surface 20S1 on the outer side of the second resin portion 20 has is not particularly limited. For example, in the above embodiment, the surface 20S1 may further have another step portion that extends linearly and overlaps two gate marks 15f to 15g. Furthermore, surface 20S1 may have step portions 25 in the same number as the number of gate marks, and each step portion 25 may overlap a different gate mark, or multiple step portions may overlap the same gate mark.

[0050] In the above embodiment, the step portion 25 is formed by the inclined surface 26 that is inclined with respect to the outer surface 10S1 of the first resin portion 10. However, the step portion 25 may be formed by a surface that is approximately perpendicular to the outer surface 10S1.

[0051] In the above embodiment, the outer cover 1 is described by way of example, in which a character visible from the outside is drawn by the sticker 3 attached to the multicolor molded body 2. However, the character only needs to be located closer to the second resin part 20 than the first resin part 10 and visible from the outside, and for example, at least a part of the character may be drawn by the step part 25. FIG. 8 is a front view showing an enlarged part of an outer cover according to a modified example. The outer cover 1 of the modified example shown in FIG. 8 differs from the outer cover 1 of the above embodiment in that it further includes a step part 125 different from the step part 25, and this step part 125 differs from the step part 25 in that it is arranged differently. In this modified example, the outer surface of the lower resin part 20D, which is a part of the outer surface 20S1 of the second resin part 20, has the step part 125. The step part 125 extends to draw a rectangle and crosses the two gate marks 15f to 15g. The area surrounded by the step portion 125 on the outer surface of the lower resin part 20D is closer to the first resin part 10 than the other areas. In this way, in the outer cover 1 of this modified example, a square as a character is drawn by the step portion 125, and the square as the character is located closer to the second resin part 20 side than the first resin part 10 and overlaps with the two gate marks 15f to 15g. Even if the character is a square, it is possible to make the sink mark on the outer surface 20S1 of the second resin part 20 less noticeable. Note that a part of the character may be drawn by the step portion of the outer surface 20S1 of the second resin part 20, and another part of the character may be drawn by a sticker attached to this surface 20S1. In addition, when the second resin part 20 has translucency, for example, a sticker on which a character is drawn may be placed inside the second resin part 20, and the character may be visible from the outside and overlap with the gate marks.
