[0010] A preferred embodiment of the present invention will now be described.

[0011] The comb of the present invention includes a pair of second terminal comb teeth extending from both ends of the other of the side edges, and the first terminal comb teeth are a pair extending from both ends of one of the side edges of the base, with the multiple first comb teeth arranged between the pair of first terminal comb teeth and the multiple second comb teeth arranged between the pair of second terminal comb teeth. In this case, the comb has a pair of first terminal comb teeth extending from both ends of one of the side edges of the base and a pair of second terminal comb teeth extending from both ends of the other side edge of the base, making it easy to use each of the first terminal comb teeth and each of the second terminal comb teeth. Furthermore, if the comb is dropped, either the first terminal comb teeth or the second terminal comb teeth will come into contact with the floor or the like, preventing damage to the first and second comb teeth.

[0012] In the comb of the present invention, at one end in the direction in which the side edges extend, an imaginary first straight line extending from the tip of the second terminal comb tooth to the tip of the first terminal comb tooth whose adjacent first comb tooth is spaced apart from the tip of the adjacent first comb tooth by a larger distance may be inclined toward one end of the base compared to the direction in which the first comb teeth extend. In this case, at one end in the direction in which the side edges of the base extend, the first terminal comb tooth extends away from the adjacent first comb tooth toward its tip. This makes it easy to use the first terminal comb tooth when creating a part in hair or scooping up part of the hair.

[0013] In the comb of the present invention, the tips of the first comb teeth may be located closer to the base than an imaginary second straight line connecting the tips of the first end comb teeth. In this case, when creating a part in hair or scooping up part of the hair, the first comb teeth do not get in the way and the first end comb teeth can be easily used.

[0014] In the comb of the present invention, the base has a front and back surfaces extending from one of the two side edges along which the first comb teeth and the first terminal comb teeth extend and the other of the two side edges along which the second comb teeth extend, and a recess may be formed in the center of at least one of the front and back surfaces. In this case, the comb is easy to use because a user can easily pinch the comb by placing the pads of their fingers in the recess.

[0015] In the comb of the present invention, the base has a front and back surface that extend from one of the side edges from which the first comb teeth and the first terminal comb teeth extend and the other side edge from which the second comb teeth extend, and when viewed in plan with either the front or back surface facing upward on a horizontal surface, both ends of the side edges of the base in the direction in which the side edges extend may be curved with their centers bulging outward. In this case, when a user uses the comb by pinching the front or back surface of the base, the portion that rests on the palm is curved, making it fit comfortably in the hand.

[0016] In the comb of the present invention, one of the side edges from which the first comb teeth and the first terminal comb teeth extend and the other of the side edges from which the second comb teeth and the second terminal comb teeth extend may be offset in a direction perpendicular to the direction in which the first comb teeth and the second comb teeth extend. In this case, when using the first comb teeth and the first terminal comb teeth and when using the second comb teeth and the second terminal comb teeth, the user can pinch the comb by placing both ends in the direction in which the side edges of the base extend in the same manner against the palm of the hand, making it easy to use.

[0017] Example 1 Next, a first embodiment of a comb according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, comb 1 of the first embodiment includes a base 10, a pair of first terminal comb teeth 30L, 30R, 19 first comb teeth 31, a pair of second terminal comb teeth 50L, 50R, and 34 second comb teeth 51. For ease of explanation, as shown in FIG. 1, in a plan view (hereinafter referred to as a "plan view") in which the surface of base 10 of comb 1 faces upward and the first comb teeth 31 and the second comb teeth 51 are arranged on a horizontal plane so that they extend in the vertical direction, the direction in which the pair of first terminal comb teeth 30L, 30R and the first comb teeth 31 extend from one of both side edges of base 10 is defined as "downward," and the direction in which the pair of second terminal comb teeth 50L, 50R and the second comb teeth 51 extend from the other of both side edges of base 10 is defined as "upward." In the plan view, the direction perpendicular to the vertical direction is defined as the left-right direction. In a plan view, the front side of the base 10 of the comb 1 is the front, and the back side is the rear. In the three-dimensional Cartesian coordinate system shown in each figure, the positive direction of the X axis is the "upward direction," the negative direction of the X axis is the "downward direction," the positive direction of the Y axis is the "leftward direction," the negative direction of the Y axis is the "rightward direction," the positive direction of the Z axis is the "forward direction," and the negative direction of the Z axis is the "rearward direction."

[0018] <About base 10> As shown in Figures 1 and 3, the lower edge 10B extending in the left-right direction of the base 10 is positioned slightly lower than the right edge in a plan view, and is curved so that the center is concave upward. The upper edge 10T extending in the left-right direction of the base 10 is positioned slightly lower than the right edge in a plan view, and is curved so that the center is concave downward. The lower edge 10B and upper edge 10T of the base 10 correspond to both side edges of the base 10. The lower edge 10B of the base 10 is shifted to the right compared to the upper edge 10T.

[0019] The right edge 10R of the base 10, which extends in the vertical direction, is located to the left of the lower edge in a plan view, and is curved so as to bulge slightly to the right. The left edge 10L of the base 10, which extends in the vertical direction, is located to the left of the lower edge in a plan view, and is curved so as to bulge slightly to the left. The right edge 10R of the base 10 corresponds to one end of the direction in which both side edges of the base 10 extend. The base 10 is point-symmetrical in a plan view. In a plan view, the base 10 has a parallelogram shape that is long in the left-right direction, with straight lines connecting the rectangles formed by the upper and lower side edges 10T, 10B and the left and right side edges 10L, 10R.

[0020] As shown in FIGS. 1 to 6, the base 10 is flat. The base 10 has a front and back surfaces 11F, 11B that extend from an upper edge 10T and a lower edge 10B as upper and lower end edges and a right edge 10R and a left edge 10L as left and right end edges. The front surface 11F of the base 10 faces forward. The back surface 11B of the base 10 faces rearward. Most of the front surface 11F of the base 10 is formed by a cover 300, which will be described later (see FIGS. 6 to 8). The front surface 11F of the base 10 is flat. The back surface 11B of the base 10 is flat with a recess 13 formed in the center (see FIGS. 6 and 7). The recess 13 is long in the horizontal direction, and the vertical dimension of the left side is smaller than the vertical dimension of the right side.

[0021] <Regarding the pair of first end comb teeth 30L and 30R> As shown in FIGS. 1 and 3, the pair of first terminal comb teeth 30L, 30R extend downward from both left and right ends of the lower edge 10B of the base 10. The lower edge 10B of the base 10 corresponds to one of the two side edges of the base 10. The left first terminal comb tooth 30L has a generally triangular shape with a pointed lower end in a plan view. The left edge of the left first terminal comb tooth 30L is continuous with the left edge 10L of the base 10. The left edge of the left first terminal comb tooth 30L is curved so that its lower end is located to the right of its upper end in a plan view and bulges out to the left. The right edge of the left first terminal comb tooth 30L is curved so that its upper end is located slightly to the right of its lower end in a plan view and dents slightly to the left.

[0022] The right first terminal comb tooth 30R has a tapered shape with a narrow lower end in plan view. The lower end of the right first terminal comb tooth 30R is wider in the left-right direction than the lower end of the left first terminal comb tooth 30L in plan view. The upper end of the right first terminal comb tooth 30R is narrower in the left-right direction than the upper end of the left first terminal comb tooth 30L in plan view. The right edge of the right first terminal comb tooth 30R is continuous with the right edge 10R of the base 10. In plan view, the lower end of the right edge of the right first terminal comb tooth 30R is located slightly to the left compared to the upper end, and is curved so as to bulge slightly to the right. In plan view, the left edge of the right first terminal comb tooth 30R is inclined diagonally downward to the right from the upper end and is curved so as to be slightly concave to the right.

[0023] <Regarding the first comb tooth 31> Each of the first comb teeth 31 extends straight and parallel downward from the lower edge 10B of the base 10. The first comb teeth 31 are arranged in a row at equal intervals between the left and right first terminal comb teeth 30L, 30R. As shown in FIG. 3, the tip of each first comb tooth 31 is located closer to the base 10, i.e., higher, than an imaginary second straight line L2 connecting the tips of the left and right first terminal comb teeth 30L, 30R. The tip of each first comb tooth 31 is located gradually higher toward the left-right center. In a plan view, the curvature of an imaginary curve C1 connecting the tips of each first comb tooth 31 is smaller than the curvature of the lower edge 10B of the base 10. The length of each first comb tooth 31 gradually increases toward the left-right center.

[0024] As shown in FIG. 4, each of the first comb teeth 31 has a flat shape in which the area of ​​its side surface when viewed from either the left or right direction is larger than the area of ​​its side surface when viewed from either the front or back direction. In horizontal cross section, each of the first comb teeth 31 has an elliptical shape that bulges outward to the left and right. As shown in FIGS. 1 and 4, each of the first comb teeth 31 has a constant width from its base, which is continuous with the lower edge 10B of the base 10, to its tip (lower end). The tip of each of the first comb teeth 31 has a substantially hemispherical shape. As shown in FIG. 7, each of the first comb teeth 31 has a tapered shape in which the front-to-back width gradually narrows from its base to its tip. When viewed from either the left or right direction, each of the first comb teeth 31 has a substantially isosceles triangular shape with the tip as the apex angle. Each of the first comb teeth 31 has a symmetrical shape when viewed from the front or back. This shape of each of the first comb teeth 31 can reduce friction between the first comb teeth 31 and hair when combing.

[0025] 3, the distance D3 between the tip of the first terminal comb tooth 30R on the right side and the tip of the adjacent first comb tooth 31 is wider than the distance D1 between the tips of adjacent first comb teeth 31. The distance D4 between the tip of the first terminal comb tooth 30L on the left side and the tip of the adjacent first comb tooth 31 is narrower than the distance D3 between the tip of the first terminal comb tooth 30R on the right side and the tip of the adjacent first comb tooth 31, and is wider than the distance D1 between the tips of adjacent first comb teeth 31.

[0026] <Regarding the pair of second end comb teeth 50L, 50R> As shown in FIGS. 1 and 3, the pair of second terminal comb teeth 50L, 50R extend upward from the left and right ends of the upper edge 10T of the base 10. The upper edge 10T of the base 10 corresponds to the other of the two side edges of the base 10. In plan view, the second right terminal comb tooth 50R is shaped so that it overlaps with the first left terminal comb tooth 30L when rotated 180 degrees around the center of the base 10. The right edge of the second right terminal comb tooth 50R is continuous with the right edge 10R of the base 10. In plan view, the right edge of the second right terminal comb tooth 50R is curved so that its upper end is located to the left of its lower end and bulges to the right. In plan view, the left edge of the second right terminal comb tooth 50R is curved so that its lower end is located slightly to the left of its upper end and dents slightly to the right.

[0027] The second left end comb tooth 50L has a tapered shape with a narrow upper end in plan view. In plan view, the upper end of the second left end comb tooth 50L is wider in the left-right direction than the upper end of the second right end comb tooth 50R, and is approximately equal in left-right width to the lower end of the first right end comb tooth 30R. The left edge of the second left end comb tooth 50L is continuous with the left edge 10L of the base 10. In plan view, the left edge of the second left end comb tooth 50L is located slightly to the right compared to the lower end, and is curved so as to bulge slightly to the left. In plan view, the right edge of the second left end comb tooth 50L is curved so as to be recessed slightly to the left.

[0028] <Regarding the second comb teeth 51> Each second comb tooth 51 extends straight and parallel upward from the upper edge 10T of the base 10. The second comb teeth 51 are aligned in a row at equal intervals between the left and right second terminal comb teeth 50L, 50R. As shown in FIG. 3, the distance D2 between the tips of the second comb teeth 51 is approximately ¾ of the distance D1 between the tips of the first comb teeth 31. The tip of each second comb tooth 51 is located closer to the base 10, i.e., lower, than an imaginary second straight line L3 connecting the tips of the left and right second terminal comb teeth 50L, 50R. The tip of each second comb tooth 51 gradually decreases downward toward the left-right center. In a plan view, the curvature of an imaginary curve C2 connecting the tips of each second comb tooth 51 is smaller than the curvature of the upper edge 10T of the base 10. The length of each second comb tooth 51 gradually increases toward the left-right center.

[0029] As shown in FIG. 5, each second comb tooth 51 has a flat shape in which the area of ​​its side surface as viewed from either the left or right direction is larger than the area of ​​its side surface as viewed from either the front or back direction. In horizontal cross section, each second comb tooth 51 has an elliptical shape that bulges outward to the left and right. As shown in FIGS. 1 and 5, each second comb tooth 51 has a constant left-right width from its base portion, which is continuous with the upper edge 10T of the base 10, to its tip (upper end). The left-right width of each second comb tooth 51 is approximately two-thirds the left-right width of each first comb tooth 31. The tip of each second comb tooth 51 has an approximately hemispherical shape. As shown in FIG. 7, each second comb tooth 51 has a tapered shape in which the front-to-back width gradually narrows from its base portion to its tip. When viewed from either the left or right direction, each second comb tooth 51 has an approximately isosceles triangular shape with the tip as the apex angle. Each second comb tooth 51 has a symmetrical front-to-back shape. Like the first comb teeth 31, the second comb teeth 51 having such a shape can reduce friction that occurs between the second comb teeth 51 and the hair when combing the hair.

[0030] 3, the distance D5 between the tip of the right second terminal comb tooth 50R and the tip of the adjacent first comb tooth 31 is wider than the distance D2 between the tips of adjacent second comb teeth 51. The distance D6 between the tip of the left second terminal comb tooth 50L and the tip of the adjacent second comb tooth 51 is approximately equal to the distance D5 between the tip of the right second terminal comb tooth 50R and the tip of the adjacent second comb tooth 51, and is wider than the distance D2 between the tips of adjacent second comb teeth 51. The shape formed by connecting the four points of the tips of the left and right first terminal comb teeth 30L, 30R and the tips of each second terminal comb tooth 50L, 50R is a parallelogram.

[0031] In a plan view of this comb 1, as shown in Figure 3, the imaginary first straight line L1 extending from the tip of the second terminal comb tooth 50R on the right side to the tip of the first terminal comb tooth 30R on the right side is inclined to the right compared to the direction in which the first comb tooth 31 extends.

[0032] <About the components of Comb 1> As shown in Figs. 6 to 10, the comb 1 is composed of a main body 100, a weight 200, and a cover 300. The main body 100 and the cover 300 are made of resin. The surfaces of the main body 100 and the cover 300 are plated with a plating solution containing an antistatic agent. This allows the comb 1 to reduce the generation of static electricity when combing hair. The weight 200 is made of metal.

[0033] <About the main unit 100> The main body 100 has a rear wall 110, upper and lower side edges 130T, 130B, left and right side edges 130L, 130R, a pair of first terminal comb teeth 30L, 30R, 19 first comb teeth 31, a pair of second terminal comb teeth 50L, 50R, and 34 second comb teeth 51. The rear wall 110 of the main body 100 is a thin, flat plate and forms the back surface of the base 10. The rear surface of the rear wall 110 corresponds to the back surface of the base 10. The upper and lower side edges 130T, 130B of the main body 100 are the upper and lower side edges 10T, 10B of the base 10. The left and right side edges 130L, 130R of the main body 100 form the rear portions of the left and right side edges 10L, 10R of the base 10. The main body 100 is surrounded by a rear wall portion 110, upper and lower side edges 130T, 130B, and left and right side edges 130L, 130R, and forms a storage recess 170 that opens forward.

[0034] The main body 100 has three cylindrical protrusions 180A, 180B, and 180C that are substantially cylindrical and four hook-shaped protrusions 190A, 190B, 190C, and 190D within the storage recess 170. As shown in FIG. 8, the three cylindrical protrusions 180A, 180B, and 180C protrude forward from the front surface of the rear wall 110 at the center of the storage recess 170 and at the vertical centers of both left and right ends of the storage recess 170. The first cylindrical protrusion 180A provided at the center of the storage recess 170 has a portion of its right side cut out. The first cylindrical protrusion 180A has a protrusion 181 extending leftward from its left side. A pair of second cylindrical protrusions 180B and 180C provided at the vertical centers of both left and right ends of the storage recess 170 have oval shapes that are long in the left-right direction in a plan view.

[0035] Four hook-shaped protrusions 190A, 190B, 190C, and 190D protrude forward from the front surface of rear wall 110 near the four corners of storage recess 170. First hook-shaped protrusion 190A provided at the upper left corner of storage recess 170 has, in plan view, a first piece 191A extending downward from the upper end to the lower end, and a second piece 192A extending diagonally downward to the right from the upper end of first piece 191A. Second hook-shaped protrusion 190B provided at the lower left corner of storage recess 170 has, in plan view, a first piece 191B extending diagonally upward to the left from the lower end to the upper end, and a second piece 192B extending diagonally upward to the right from the lower end of first piece 191B. Third hook-shaped protrusion 190C provided at the upper right corner of storage recess 170 has, in plan view, a first piece 191C extending diagonally downward to the right from the upper end to the lower end, and a second piece 192C extending diagonally downward to the left from the upper end of first piece 191C. Fourth hook-shaped protrusion 190D provided at the lower right corner of storage recess 170 has, in plan view, a first piece 191D extending upward from the lower end to the upper end, and a second piece 192D extending diagonally upward to the left from the lower end of first piece 191D.

[0036] <About the 200mm weight> As shown in Figures 6 to 8 and 10, weight 200 is stored in a storage recess 170 formed in main body 100. As shown in Figures 8 and 10, weight 200 is in the shape of a flat plate that is long in the left-right direction. In plan view, upper edge 200T of weight 200 is aligned with the underside of upper edge 10T of base 10, and is curved so that the center is concave downward. In plan view, lower edge 200B of weight 200 is aligned with the upper surface of lower edge 10B of base 10, and is curved so that the center is concave upward.

[0037] In plan view, weight 200 has a substantially circular through-hole 201 formed in the center that penetrates in the front-to-rear direction. In plan view, this through-hole 201 has a semicircular recess 201A that protrudes rightward from the inner circumferential surface of the right-side center portion. Weight 200 has a groove 201B formed on the rear surface that is continuous with the inner circumferential surface of through-hole 201 in the left-side center portion and extends leftward. In plan view, weight 200 has a pair of left and right notches 203L, 203R formed in the top-to-bottom center portions on both left and right ends that extend in the left-to-right direction. Each of left and right notches 203L, 203R has a substantially semicircular shape on the left-to-right center portion side.

[0038] The upper left corner of weight 200 is shaped to fit inside first hook-shaped protrusion 190A when weight 200 is stored in storage recess 170 formed in main body 100. The lower left corner of weight 200 is shaped to fit inside second hook-shaped protrusion 190B when weight 200 is stored in storage recess 170 formed in main body 100. The upper right corner of weight 200 is shaped to fit inside third hook-shaped protrusion 190C when weight 200 is stored in storage recess 170 formed in main body 100. The lower right corner of weight 200 is shaped to fit inside fourth hook-shaped protrusion 190D when weight 200 is stored in storage recess 170 formed in main body 100.

[0039] 10 , when weight 200 is stored in storage recess 170 formed in main body 100, first cylindrical protrusion 180A of main body 100 is inserted into through-hole 201, protrusion 181 extending leftward from first cylindrical protrusion 180A fits into groove 201B that is continuous with through-hole 201 and extends leftward, and second cylindrical protrusions 180B, 180C of main body 100 are inserted into left and right notches 203L, 203R. When weight 200 is stored in storage recess 170 formed in main body 100, the left, right, top, and bottom corners fit inside hook-shaped protrusions 190A, 190B, 190C, 190D of main body 100. This positions weight 200 within storage recess 170 of main body 100. The weight 200 is fixed in the storage recess 170 of the main body 100 by adhering the rear surface to the front surface of the storage recess 170 of the main body 100 .

[0040] As shown in Figures 8 and 10, weight 200 has a semicircular upper-left cutout 205A that protrudes downward from the upper left corner toward the left-right center. Weight 200 has a semicircular lower-left cutout 205B that protrudes upward from the lower left corner toward the left-right center. Weight 200 has a semicircular upper-right cutout 205C that protrudes downward from the upper right corner toward the left-right center. Weight 200 has a semicircular lower-right cutout 205D that protrudes upward from the lower right corner toward the left-right center. When the cover 300 described below is attached to the main body 100, the upper left notch 205A, the lower left notch 205B, the upper right notch 205C, and the lower right notch 205D are used to insert the folded pieces 333A, 333B, 333C, and 333D of each protruding wall 330A, 330B, 330C, and 330D of the cover 300.

[0041] <About Cover 300> As shown in Figures 1, 6 to 8, the cover 300 is attached to the main body 100 so as to cover the storage recess 170 of the main body 100 that stores the weight 200. The front surface of the cover 300 constitutes most of the surface of the base 10. The cover 300 is long in the left-right direction and has a thin, flat plate shape. As shown in Figures 1, 8 and 9, the upper edge 300T of the cover 300 is aligned with the underside of the upper edge 10T of the base 10 in a plan view, and is curved so that the center is concave downward. The lower edge 300B of the cover 300 is aligned with the upper surface of the lower edge 10B of the base 10 in a plan view, and is curved so that the center is concave upward.

[0042] As shown in FIG. 1 , the left edge 300L of the cover 300 constitutes the left edge 10L of the base 10. The lower end of the left edge 300L of the cover 300 is continuous with the left edge of the first left terminal comb tooth 30L. The upper end of the left edge 300L of the cover 300 is continuous with the left edge of the second left terminal comb tooth 50L. The left edge 300L of the cover 300 is curved to bulge slightly to the left in a plan view. The right edge 300R of the cover 300 constitutes the right edge 10R of the base 10.

The upper end of the right edge 300R of the cover 300 is continuous with the right edge of the second right terminal comb tooth 50R. The right edge 300R of the cover 300 is curved to bulge slightly to the right in a plan view.

[0043] 9, the cover 300 has three substantially cylindrical insertion protrusions 310A, 310B, and 310C and four protruding walls 330A, 330B, 330C, and 330D. The three insertion protrusions 310A, 310B, and 310C protrude rearward from the back surface (rear surface) of the cover 300 at the center of the back surface of the cover 300 and at the vertical centers of both left and right ends of the back surface of the cover 300. The first insertion protrusion 310A provided at the center of the back surface of the cover 300 has a protrusion piece 311 extending rightward from the right side surface. The outer diameter of the first insertion protrusion 310A is smaller than the inner diameter of the first cylindrical protrusion 180A provided in the storage recess 170 of the main body 100. The vertical width of the protruding piece 311 is smaller than the width of the notch on the right side surface of the first cylindrical protrusion 180A provided in the storage recess 170 of the main body 100. The pair of second insertion protrusions 310B, 310C provided in the vertical center of both left and right ends of the back surface of the cover 300 are smaller than the upper width of each of the second cylindrical protrusions 180B, 180C provided in the storage recess 170 of the main body 100.

[0044] Four protruding walls 330A, 330B, 330C, and 330D protrude rearward from the back surface of cover 300 near the four corners of the back surface of cover 300. First protruding wall 330A, located at the upper left corner of cover 300, has a first piece 331A extending downward from the top to the bottom along the left edge of cover 300, a second piece 332A extending diagonally downward to the right from the top end of first piece 331A, and a folded piece 333A extending downward from the right end of second piece 332A. Second protruding wall 330B, located at the lower left corner of cover 300, has a first piece 331B extending upward from the bottom to the top along the left edge of cover 300, a second piece 332B extending diagonally upward to the right from the bottom end of the first piece, and a folded piece 333B extending upward from second piece 332B. Third protruding wall 330C provided at the upper right corner of cover 300 has a first piece 331C extending downward from the upper end to the lower end along the right edge of cover 300, a second piece 332C extending diagonally downward to the left from the upper end of first piece 331C, and a folded piece 333C extending downward from the left end of second piece 332C. Fourth protruding wall 330D provided at the lower right corner of cover 300 has a first piece 331D extending upward from the lower end to the upper end along the right edge of cover 300, a second piece 332D extending diagonally upward to the left from the lower end of first piece 331D, and a folded piece 333D extending upward from second piece 332D.

[0045] 6 and 7, when the cover 300 is attached to the main body 100, the first insertion protrusion 310A is inserted into the first cylindrical protrusion 180A of the main body 100, and the protrusion piece 311 extending rightward from the right side surface of the first insertion protrusion 310A is inserted into the notch in the right side surface of the first cylindrical protrusion 180A of the main body 100 and into the semicircular recess 201A protruding rightward of the through-hole 201 of the weight 200. When the cover 300 is attached to the main body 100, the pair of second insertion protrusions 310B, 310C are inserted into the second cylindrical protrusions 180B, 180C of the main body 100, respectively. When the cover 300 is attached to the main body 100, the first pieces 331A, 331B, 331C, 331D and second pieces 332A, 332B, 332C, 332D of the upper, lower, left, and right protruding walls 330A, 330B, 330C, 330D are arranged along the outer edges of the first pieces 191A, 191B, 191C, 191D and second pieces 192A, 192B, 192C, 192D of the hook-shaped protrusions 190A, 190B, 190C, 190D of the main body 100, and the folded pieces 333A, 333B, 333C, 333D are inserted into the notches 205A, 205B, 205C, 205D formed on the upper, lower, left, right, and right of the weight 200. This positions the cover 300 relative to the main body 100. The cover 300 is adhered and fixed to the main body 100 by inserting the insertion protrusions 310A, 310B, and 310C into the cylindrical protrusions 180A, 180B, and 180C into which adhesive has been poured.

[0046] In this comb 1, the base 10 is formed by the main body 100 and the cover 300, and the base 10 has a thickness in the front-to-rear direction. This makes it easy for a user to grip the base 10 when using this comb 1. Furthermore, even though the base 10 of this comb 1 has a thickness in the front-to-rear direction, the rear wall 110 of the main body 100 and the cover 300 are thin and flat, which prevents deformation of the resin that occurs during manufacturing and does not impair the design of the front and back surfaces 11F, 11B of the base 10.

[0047] This comb 1 is easy to operate because the weight 200 is stored in the base 10. In addition, this comb 1 can fill the space between the main body 100 and the cover 300 by placing the weight 200 there, thereby preventing reverberation at the base 10 when the comb 1 is dropped.

[0048] As described above, the comb 1 of Example 1 comprises a base 10, a pair of first terminal comb teeth 30L, 30R extending from both ends of the lower edge 10B of the base 10, 19 first comb teeth 31 aligned between the first terminal comb teeth 30L, 30R and extending in the same direction from the lower edge 10B, a pair of second terminal comb teeth 50L, 50R extending from both ends of the upper edge 10T, and 34 second comb teeth 51 aligned between the second terminal comb teeth 50L, 50R and extending in the same direction from the upper edge 10T, the distance between the tips of adjacent first comb teeth 31 is wider than the distance between the tips of adjacent second comb teeth 51, and the distance between the tip of the right-side first terminal comb tooth 30R and the tip of the adjacent first comb tooth 31 is wider than the distance between the tips of adjacent first comb teeth 31.

[0049] In this comb 1, the distance between the tip of the first end comb tooth 30R on the right side and the tip of the adjacent first comb tooth 31 is wider than the distance between the tips of the adjacent first comb teeth 31, so this first end comb tooth 30R can be used to make a part in the hair or to scoop up part of the hair.

[0050] Therefore, the comb 1 of Example 1 is easy to use.

[0051] In the comb 1 of Example 1, the imaginary first straight line L1 extending from the tip of the second right-side terminal comb tooth 50R to the tip of the first right-side terminal comb tooth 30R is inclined to the right compared to the direction in which the first comb teeth 31 extend. Therefore, in this comb 1, the first right-side terminal comb tooth 30R extends away from the adjacent first comb tooth 31 toward its tip. Therefore, with this comb 1, the first terminal comb tooth 30R can be easily used when creating a part in hair or scooping up part of the hair.

[0052] In the comb 1 of Example 1, the tip of each of the first comb teeth 31 is located closer to the base 10 than the imaginary second straight line L2 connecting the tips of each of the first terminal comb teeth 30L, 30R. Therefore, when using this comb 1 to create a part in hair or scoop up part of the hair, the first comb teeth 31 do not get in the way, making it easy to use each of the first terminal comb teeth 30L, 30R.

[0053] In the comb 1 of Example 1, the base 10 has front and back surfaces 11F and 11B that extend from a lower edge 10B from which the first comb teeth 31 and the first terminal comb teeth 30L, 30R extend, and an upper edge 10T from which the second comb teeth 51 and the second terminal comb teeth 50L, 50R extend, and a recess 13 is formed in the center of the back surface 11B. This makes the comb 1 easy to use because a user can easily pinch the comb 1 by placing the pads of their fingers against the recess 13.

[0054] In the comb 1 of Example 1, the base 10 has front and back surfaces 11F and 11B that extend from a lower edge 10B from which the first comb teeth 31 and the first terminal comb teeth 30L and 30R extend, and an upper edge 10T from which the second comb teeth 51 and the second terminal comb teeth 50L and 50R extend. When viewed from above with the front surface facing upward and placed on a horizontal surface, the left and right side edges 10L and 10R are curved and bulge outward at their centers. Therefore, when the user uses the comb 1 by pinching the front and back surfaces 11F and 11B of the base 10, the curved portions that come into contact with the palm of the hand fit comfortably in the hand.

[0055] In the comb 1 of Example 1, the lower edge 10B from which the first comb teeth 31 and the first terminal comb teeth 30L, 30R extend is shifted to the right compared to the upper edge 10T from which the second comb teeth 51 and the second terminal comb teeth 50L, 50R extend. In other words, the lower edge 10B of the base 10 and the upper edge 10T of the base 10 are shifted in a direction perpendicular to the direction in which the first comb teeth 31 and the second comb teeth 51 extend. Therefore, when using the first comb teeth 31 and the first terminal comb teeth 30L, 30R and when using the second comb teeth 51 and the second terminal comb teeth 50L, 50R, the user can pinch the comb 1 by placing both ends on the palm of the hand in the same way, making it easy to use.

[0056] The present invention is not limited to the first embodiment described above with reference to the drawings, and the following embodiments are also included within the technical scope of the present invention. (1) For both the left and right first terminal comb teeth 30L, 30R, the distance between the tip of the first comb tooth 31 and the tip of the adjacent first comb tooth 31 may be wider than the distance between the tips of the adjacent first comb teeth 31. (2) The tip of each first comb tooth 31 may be located on the imaginary second straight line L2 or on the opposite side of the imaginary second straight line L2 from the base 10. The tip of each second comb tooth 51 may be located on the imaginary third straight line L3 or on the opposite side of the imaginary third straight line L3 from the base 10. (3) Recesses may be formed on both the front and rear surfaces 11F, 11B of the base 10, or recesses may not be formed on either the front and rear surfaces 11F, 11B. (4) The left and right side edges 10L, 10R of the base 10 may extend linearly in the vertical direction. (5) The lower edge 10B and the upper edge 10T of the base 10 do not need to be misaligned in the left-right direction. (6) The comb 1 does not have to be made up of three members, namely, the main body 100, the weight 200, and the cover 300, but may be made up of one member. [Explanation of symbols]
