Embodiments for Carrying Out the Invention

[0011] Hereinafter, with reference to the accompanying drawings, this embodiment will be described in detail. <Schematic Configuration of Hairbrush 1> FIG. 1 is a perspective view showing the hairbrush 1 according to this embodiment. FIG. 2 is a plan view of the hairbrush 1 as viewed from the thickness direction. FIG. 3 is a side view of the hairbrush 1. First, with reference to FIGS. 1 to 3, the configuration of the hairbrush 1 to which the present embodiment is applied will be described. In the following description, after describing the schematic configuration and operation of the hairbrush 1, the details of each part will be described.

[0012] As shown in FIG. 1, the hairbrush 1 includes a handle 2 extending in a rod shape and a brush head 3 provided at the longitudinal tip 2a of the handle 2. The brush head 3 includes a head base 30 formed with a dimension in the width direction larger than that of the handle 2, and a plurality of brush hairs 41 provided on the head base 30 so as to protrude in the thickness direction of the head base 30.

[0013] A user of the hairbrush 1 holds the handle 2 by hand and, for example, moves the brush head 3 in the width direction to brush the hair with the brush hairs 41. In the following description, the longitudinal direction of the handle 2 may be simply referred to as the "longitudinal direction". Also, the thickness direction of the brush head 3 may be simply referred to as the "thickness direction", and the width direction of the brush head 3 may be simply referred to as the "width direction". Further, a virtual central axis extending in the longitudinal direction at the center in the width direction of the brush is defined as the axis P (see FIG. 2) of the hairbrush 1.

[0014] <Detailed Configuration of Hairbrush 1> As shown in FIG. 2, when viewed from the thickness direction, the handle 2 is schematically formed in a so-called teardrop shape. More specifically, the handle 2 has a configuration in which an elliptical portion (base end portion) 21 formed in an elliptical shape and a constriction portion 23 with a reduced width dimension are continuous in the longitudinal direction. The elliptical portion 21 includes the base end 2c of the handle 2. Further explaining, the elliptical portion 21 is formed such that the width dimension gradually decreases from the width maximum portion 22 where the width dimension of the handle 2 is formed to be the largest toward the base end 2c. Similarly, the elliptical portion 21 is formed such that the width dimension gradually decreases from the width maximum portion 22 toward the constriction portion 23.

[0015] The throttle portion 23 has a minimum throttle portion 24 formed with the smallest width dimension in the handle 2. To explain further, the throttle portion 23 is formed such that the width dimension gradually decreases from the elliptical portion 21 toward the minimum throttle portion 24. On the other hand, the throttle portion 23 is formed such that the width dimension gradually increases from the minimum throttle portion 24 toward the brush head 3. Note that the throttle portion 23 includes the tip portion 2a of the handle 2. However, in this embodiment, since the handle 2 is integrally formed with the brush head 3 (described later), the boundary between the handle 2 and the brush head 3 cannot be clearly distinguished in terms of shape. Therefore, in this specification, the tip portion 2a of the handle 2 is conceptually defined by focusing on the respective functions of the handle 2 and the brush head 3.

[0016] The handle 2 is formed in the elliptical portion 21 and has a first pointed portion 100 that tapers in the longitudinal direction (details will be described later). Also, the handle 2 has a maximum width portion 22 on the proximal end 2c side rather than the central portion in the longitudinal direction. The handle 2 has a throttle portion 23 on the tip portion 2a side rather than the central portion in the longitudinal direction.

[0017] The brush head 3 is a structure that holds the brush bristles 41. The brush head 3 includes a head base 30 and a brush bristle assembly (brush bristle structure) 40 having the brush bristles 41.

[0018] As shown in FIG. 2, when viewed from the thickness direction, the head base 30 is roughly formed in a so-called bell shape. More specifically, when viewed from the thickness direction, the head base 30 includes a head tip portion (tip portion) 31 that includes the tip 3c and is formed to be convex in an arc shape, and a wide portion 33 formed on the handle 2 side so as to have the largest width dimension. And the head base 30 gradually increases in width dimension from the head tip portion 31 toward the wide portion 33, and gradually decreases in width dimension from the wide portion 33 toward the throttle portion 23 of the handle 2.

[0019] Fig. 4(a) is a plan view with the brush hair assembly 40 omitted from Fig. 2, (b) is a sectional view taken along line IVb-IVb of (a), and (c) is a sectional view taken along line IVc-IVc of (a). As shown in Fig. 4(a), the head base 30 has a mounting recess 34 to which the brush hair assembly 40 is attached. The mounting recess 34 is formed in a mounting broad surface 36 facing one side in the thickness direction of the head base 30 (the upper side in Fig. 4(a)). The mounting recess 34 is formed in an elliptical shape and has a bottom when viewed from the thickness direction. The head base 30 has an opening edge 35 surrounding the opening of the mounting recess 34. As shown in Fig. 4(b), the opening edge 35 is formed to project inward of the mounting recess 34 so as to narrow the opening area compared to the bottom of the mounting recess 34.

[0020] As shown in Fig. 2, the brush hair assembly 40 has a plurality of brush hairs 41 and a rubber seat 45 which is a cushion body to which the plurality of brush hairs 41 are fixed. The brush hair 41 is composed of a bamboo pin member. A circumferential groove (not shown) is formed on the outer peripheral surface of the proximal end side of the brush hair 41. As shown in Figs. 3 and 4(b), the rubber seat 45 is formed in a dome shape so as to bulge in one direction in the thickness direction (the upper side in Fig. 4(b)). More specifically, the rubber seat 45 has a so-called thin shape with dimensions in the longitudinal and width directions larger than those in the thickness direction. For this rubber seat 45, rubbers such as ethylene propylene rubber (EPDM), natural rubber (NR), nitrile rubber (NBR), styrene-butadiene rubber (SBR), and silicone rubber (SI) may be used. A plurality of through holes 47 for holding the brush hair 41 so as to project in one direction in the thickness direction are formed in the rubber seat 45 (see Fig. 3).

[0021] The brush hair assembly 40 is attached to the rubber seat 45 such that the tip side of the brush hair 41 protrudes in the thickness direction by fitting the circumferential groove (not shown) of the brush hair 41 into each through hole 47 of the rubber seat 45. And, as shown in Fig. 4(b), the brush hair assembly 40 is held by the head base 30 by fixing the outer peripheral edge 48 of the rubber seat 45 to the opening edge 35. Note that the fixing to the opening edge 35 may be in a manner using an adhesive or in a manner engaging with the opening edge 35. Also, as the adhesive, for example, a silicone-based adhesive may be used.

[0022] As shown in Fig. 2, such a brush hair assembly 40 has a plurality of brush hairs 41 provided on the head base 30 in the width direction and the longitudinal direction. Specifically, the brush hair assembly 40 has the brush hairs 41 arranged so as to surround quadruple six brush hairs 41 provided in series in the longitudinal direction on the center side. Further, since the rubber seat 45 bulges in a dome shape, the brush hairs 41 located on the outer peripheral side are more inclined. To explain further, the brush hairs 41 located on the outer peripheral side have a smaller angle with respect to the mounting broad surface 36 compared to the brush hairs 41 located on the inner peripheral side. Also, as shown in Fig. 2, among the plurality of brush hairs 41, the brush hairs 41 at the outer peripheral ends extend radially when viewed from the thickness direction.

[0023] As shown in Fig. 4(b), the brush head 3 has a base communication hole 37 formed at the head tip portion 31 of the head base 30 and communicating with the mounting recess 34, and a seat communication hole 49 formed on the handle 2 side of the rubber seat 45. That is, when the brush hair assembly 40 is pressed and elastically deformed during brushing, the air between the brush hair assembly 40 and the mounting recess 34 is discharged through the base communication hole 37 and the seat communication hole 49. On the other hand, when the brush hair assembly 40 elastically returns, air flows into the space between the brush hair assembly 40 and the mounting recess 34 through the base communication hole 37 and the seat communication hole 49. With such a configuration, the brush hair assembly 40 has cushioning properties. The head base 30 is formed on the handle 2 side of the side edge portions (side portions) 38A and 38B in the width direction and has second pointed portions 200A and 200B that are pointed in the width direction (details will be described later).

[0024] Now, as shown in FIG. 4(a), this hairbrush 1 employs a base member 10 (hairbrush base material) in which the head base 30 and the handle 2 are integrally formed. That is, when viewed by member, the hairbrush 1 is generally configured by attaching a brush hair assembly 40 to a thin base member 10. As shown in FIG. 3, the base member 10 has a flat portion 11 formed with a substantially constant thickness dimension, and an outer peripheral end portion 12 formed around the flat portion 11 and having a thickness dimension that gradually decreases as it moves away from the flat portion 11.

[0025] As shown in FIG. 4(a), the flat portion 11 is formed from the head tip portion 31 of the head base 30 to the elliptical portion 21 of the handle 2. This flat portion 11 includes the mounting wide surface 36 on which the above-described mounting concave portion 34 is formed. As shown in FIG. 4(b), the outer peripheral end portion 12 is formed with a substantially V-shaped cross-sectional shape in the thickness direction. That is, a main surface 15 directed toward one side in the thickness direction and a back surface 16 directed toward the other side in the thickness direction extend so as to approach each other from the flat portion 11 toward the outer peripheral end. That is, the main surface 15 and the back surface 16 are continuous via a ridge line R1 that becomes the outer peripheral end of the base member 10. Also, as shown in FIG. 4(a), the ridge line R1 is formed over the entire circumference of the outer peripheral end portion 12. Note that the base communication hole 37 described above opens in the main surface 15 of the head tip portion 31 of the head base 30.

[0026] Also, as shown in FIG. 4(c), the head base 30 and the handle 2 are integrally formed by a laminate formed by laminating bamboo materials 17. Here, the bamboo material 17 is a thin plate-like member. In the illustrated head base 30 and handle 2, the lamination direction of the bamboo materials 17 is oriented in the width direction.

[0027] <Massage function> Figure 5 is a view from the V direction of FIG. 4(a). As shown in FIG. 4(a), the hairbrush 1 has a massage function by including the above-described first tip portion 100 and second tip portions 200A and 200B. Hereinafter, the first tip portion 100 and the second tip portions 200A and 200B will be described.

[0028] <First tip portion 100> First, the first tip portion 100 will be described. The first tip portion 100 is formed to include the proximal end 2c in the elliptical portion 21 of the handle 2. This first tip portion 100 is pointed in the longitudinal direction. Specifically, as shown in FIG. 5, one side surface 101 on one side (the left side in FIG. 5) and the other side surface 102 on the other side (the right side in FIG. 5) with respect to the axis P are pointed so as to form a ridge line R2. That is, the first tip portion 100 is pointed such that the ridge line R1 and the ridge line R2 intersect. In other words, the proximal end 2c of the handle 2 is pointed in a conical shape with the four surfaces of one side surface 101 and the other side surface 102 on the main surface 15 and one side surface 101 and the other side surface 102 on the back surface 16 as the apex.

[0029] <Second tip portions 200A and 200B> Next, the second tip portions 200A and 200B will be described. As shown in FIG. 4(a), the second tip portions 200A and 200B are formed opposite to the both side edges 38A and 38B of the head base 30 so as to sandwich the handle 2 in the width direction. The second tip portions 200A and 200B are each formed on the handle 2 side and project in the width direction. That is, the second tip portions 200A and 200B constitute the above-described wide portion 33. More specifically, when viewed from the thickness direction, the length D from the opening edge 35 to the outer peripheral end (ridge line R1) is formed larger for the second tip portions 200A and 200B than any portion on the head tip portion 31 side of the head base 30. Further, the second tip portions 200A and 200B project in the width direction from the virtual reference line Q (see FIG. 2) connecting the tips of the brush hairs 41 at the outer peripheral end.

[0030] Even at the second tips 200A and 200B, the main surface 15 and the back surface 16 are continuous via the ridge line R1 (see Fig. 4(b)). On the other hand, as shown in Fig. 4(a), the second tips 200A and 200B are formed to be convex in an arc shape when viewed from the thickness direction. To explain further, at the second tips 200A and 200B, the tip 3c side and the base end 2c side are gently continuous compared to the first tip 100.

[0031] Fig. 6 is a view taken along the arrow VI in Fig. 4(a). Here, the configurations of the second tips 200A and 200B will be described while comparing them with each other. First, as shown in Fig. 6, the protruding amount L1 of the second tip 200A is slightly larger than the protruding amount L2 in the width direction of the second tip 200B. Specifically, the second tip 200A is formed to be larger in the width direction by the difference L1 - L2 compared to the second tip 200B. Also, as shown in Fig. 4(a), the second tip 200A is formed at a position slightly closer to the tip 3c of the head base 30 by the length L3 compared to the second tip 200B. Thus, the second tips 200A and 200B have a shape that is non-axisymmetric with respect to the axis P. Note that the first tip 100 and the second tips 200A and 200B each have a different shape. To explain further, when viewed from the thickness direction, the first tip 100, the second tip 200A, and the second tip 200B are sharply pointed in this order.

[0032] Next, the structure around the second tips 200A and 200B will be described. First, as shown in Fig. 4(a), the head base 30 includes first arc connection portions 18A and 18B that smoothly connect the second tips 200A and 200B and the side edge portions 28A and 28B of the handle 2 so as to be concave in an arc shape when viewed from the thickness direction. Note that the first arc connection portions 18A and 18B and the side edge portions 28A and 28B are part of the outer peripheral end portion 12 of the hairbrush 1.

[0033] The first arc connecting portions 18A and 18B are formed from the side edge portions 28A and 28B in the constriction portion 23 of the handle 2 to the second pointed portions 200A and 200B. Further, as described above, the second pointed portion 200A is formed at a position closer to the tip 3c by a length L3 compared to the second pointed portion 200B, and the curvature of the first arc connecting portion 18A is formed smaller than that of the first arc connecting portion 18B. Further, in each of the first arc connecting portions 18A and 18B, it extends in an arc shape such that the ridge line R1 is concave when viewed from the thickness direction.

[0034] Furthermore, the head base 30 has second arc connecting portions 19A and 19B that connect the second pointed portions 200A and 200B and the head tip portion 31 sides of the side edge portions 38A and 38B of the head base 30 in an arc shape that is concave when viewed from the thickness direction. The curvature of the second arc connecting portions 19A and 19B is smaller than that of the first arc connecting portions 18A and 18B. Note that the second arc connecting portions 19A and 19B and the side edge portions 38A and 38B are part of the outer peripheral end portion 12 of the hairbrush 1.

[0035] As shown in FIG. 4(a), the outer peripheral end portion 12 of the hairbrush 1 around the second pointed portion 200A (200B) extends in an arc shape that is concave at the first arc connecting portion 18A (18B) when viewed from the thickness direction. Similarly, the outer peripheral end portion 12 of the hairbrush 1 extends in an arc shape that is convex at the second pointed portion 200A (200B) and extends in an arc shape that is concave at the second arc connecting portion 19A (19B).

[0036] FIG. 7(a) is a cross-sectional view taken along line VIIa-VIIa of FIG. 4(a), (b) is a cross-sectional view taken along line VIIb-IVIIb of FIG. 4(a), and (c) is a cross-sectional view taken along line VIIc-VIIc of FIG. 4(a). As shown in FIGS. 7(a) and (b), in the first arc connecting portion 18A (18B), the front main surface 15 and the back surface 16 are continuously connected via a ridge line R1 so as to form a more acute angle than the second arc connecting portion 19A (19B). Further, as shown in FIGS. 7(b) and (c), in the first arc connecting portion 18A (18B), the front main surface 15 and the back surface 16 are continuously connected via a ridge line R1 so as to form a more acute angle than the side edge portions 28A (28B) in the elliptical portion 21 of the handle 2.

[0037] <Operation of the hairbrush 1> FIG. 8 is a schematic diagram for explaining one aspect of brushing with the hairbrush 1. Next, the operation of the hairbrush 1 will be described. Note that the gripping method and usage method of the hairbrush 1 in the following description are representative examples. As shown in FIG. 8, first, during brushing, the elliptical portion 21 of the handle 2 is gripped by pinching it with the three fingers, i.e., the middle finger F3, the ring finger F4, and the little finger F5, and the palm F0, and at the same time, the constriction portion 23 is pinched by the thumb F1 and the index finger F2. In this state, since the ridge line R1 is formed on the elliptical portion 21 and the constriction portion 23 of the handle 2, the hand is less likely to slip and a good brushing experience can be obtained.

[0038] FIG. 9(a) is a schematic diagram for explaining one aspect of the massage using the first tip portion 100 of the hairbrush 1, and (b) is a schematic diagram for explaining another aspect of the massage using the first tip portion 100 of the hairbrush 1. Subsequently, a massage method using the hairbrush 1 will be described. First, a massage method using the first tip 100 will be described. As shown in FIG. 9(a), in the massage method using the first tip 100, the user of the hairbrush 1 grips the throttle portion 23 of the handle 2 with five fingers (F1 to F5), and presses the first tip 100 against the pressed portion D1, which is an arbitrary part of the user's body, in the longitudinal direction (acupressure method, see arrow A1). At this time, since the elliptical portion 21 of the handle 2 is formed wider than the throttle portion 23, it is difficult for the hairbrush 1 pushed back from the pressed portion D1 to slip out of the hand. Therefore, the force applied to the hand is directly converted into the pressing force on the pressed portion D1.

[0039] On the other hand, when it is desired to press a pressed portion D2 such as the back, for example, in the above pressing method, the first tip 100 may be difficult to reach the pressed portion D2. In this case, as shown in FIG. 9(b), by gripping the head base 30 with five fingers (F1 to F5), a large distance is ensured between the hand and the first tip 100. As a result, the first tip 100 can be pressed against the difficult-to-reach pressed portion D2 (see arrow A2). At this time, since the second tips 200A and 200B are sharp in the width direction, by aligning the little finger F5 along the second tip 200A and the palm F0 along the second tip 200B, it becomes difficult for the hairbrush 1 to slip out of the hand. Further explanation is as follows. For example, when gripping the brush hairs 41 toward the palm F0, when the brush hairs 41 interfere with the palm F0 and it is difficult to grip, the anti-slip effect of the second tips 200A and 200B is effective. When pressing the first tips 100 against the pressed portions D1 and D2, as described above, since the lamination direction of the base member 10 is oriented in the width direction, even if the hairbrush 1 is formed thin, it is difficult to bend in the thickness direction. That is, the force applied to the hand is easily transmitted directly to the pressed portions D1 and D2.

[0040] FIG. 10 is a schematic diagram for explaining an aspect of the massage using the second tips 200A and 200B of the hairbrush 1. Next, a massage method using the second tips 200A and 200B will be described. First, as shown in FIG. 10, in the massage using the second tip 200B, the elliptical portion 21 of the handle 2 is gripped with five fingers (F1 to F5) so as to apply a force in the circumferential direction (see arrow A3) to press the pressed portion D3. In this method, compared with the massage using the first tip 100, the positional relationship between the pressing portion and the hand and the direction of applying force are different, and further, since the shape of the second tip 200B is different from that of the first tip 100, the pressed portion D3 is stimulated with a pressing feeling different from that of the first tip 100. Also, since the shapes of the second tips 200A and 200B are different, by turning the hairbrush 1 over and switching to the second tip 200A and pressing it against the pressed portion D3, the pressed portion D3 is stimulated with a different pressing feeling. At this time, since the second tips 200A and 200B protrude in the width direction from the virtual reference line Q (see FIG. 2), the second tips 200A and 200B can be pressed deeply against the pressed portion D3. Also, even when the second tips 200A and 200B are pressed against the pressed portion D3, the brush hairs 41 are less likely to interfere with the pressed portion D3 and its periphery.

[0041] FIG. 11 is a schematic diagram for explaining an aspect of the massage using the first arc connection portions 18A and 18B of the hairbrush 1. As shown in FIG. 11, in the massage using the first arc connection portion 18B, the elliptical portion 21 of the handle 2 is gripped with the thumb F1 (not shown), the index finger F2, and the middle finger F3 so as to expose the ridge line R1 of the first arc connection portion 18B to the outside. Then, for example, while pressing the first arc connection portion 18B against the pressed portion D4 such as the neck, the skin is slid, that is, rubbed, whereby blood flow and lymph flow are promoted (kassa method).

[0042] Also, since the curvatures of the first arc connection portions 18A and 18B are different, by turning the hairbrush 1 over and switching to the first arc connection portion 18A and pressing it against the pressed portion D4, the pressed portion D4 is stimulated with a different pressing feeling. In these cases, since the second pointed portions 200A and 200B are formed and the first arc connection portions 18A and 18B are ensured to be long, the pressed portion D4 is stimulated over a wide range in a single operation. Further, since the second pointed portions 200A and 200B are formed, even when the first arc connection portions 18A and 18B are pressed against the skin to slide the skin, the brush hairs 41 protruding in the thickness direction are less likely to interfere with the pressed portion D4 and its periphery.

[0043] As described above, according to the hairbrush 1, since it has the first pointed portion 100 formed in the elliptical portion 21 of the handle 2 and pointed in the longitudinal direction, and the second pointed portions 200A and 200B formed in the side edge portions 38A and 38B of the head base 30 and pointed in the width direction, the range of the pressed portion that can be pressed by the acupressure method becomes wider. Thereby, it is possible to massage the pressed portions at various sites. Also, the pressed portion can be stimulated with different pressing sensations. Thereby, the effect of the massage can be enhanced. Therefore, it is possible to provide a hairbrush 1 having a high massage function.

[0044] The second pointed portions 200A and 200B are formed in the both side edge portions 38A and 38B as a pair and have a shape that is non-linearly symmetric with respect to the axis P. Therefore, by switching the second pointed portions 200A and 200B and pressing them against the pressed portion, the pressed portion is stimulated with different pressing sensations. Thereby, the effect of the massage can be further enhanced. Also, since the second pointed portions 200A and 200B protrude in the width direction from the virtual reference line Q connecting the tips of the brush hairs 41 at the outer peripheral end, the second pointed portions 200A and 200B can be deeply pressed against the pressed portion. Further, even when the second pointed portions 200A and 200B are pressed against the pressed portion, the brush hairs 41 are less likely to interfere with the pressed portion and its periphery. Due to these, it becomes easier to press the second pointed portions 200A and 200B against the pressed portion, so that the ease of massage can be enhanced. Also, since the first pointed portion 100 and the second pointed portions 200A and 200B are pointed such that the main surface 15 and the back surface 16 form a ridge line R1, the first pointed portion 100 and the second pointed portions 200A and 200B can be pointed with a simple configuration.

[0045] In addition, when viewed from the thickness direction, first arc connection portions 18A and 18B are provided to smoothly connect the second pointed portions 200A and 200B and the side edge portions 28A and 28B of the handle 2 in an arc shape that is concave. Since the main surface 15 and the back surface 16 are sharp so as to form a ridge line R1, a kassatsu method for promoting blood flow and lymph flow can be applied to the pressed portion. Further, since the second pointed portions 200A and 200B protrude in the width direction, a long ridge line R1 of the first arc connection portions 18A and 18B can be secured, and the pressed portion can be stimulated over a wide range in a single operation. At this time, since the second pointed portions 200A and 200B protrude in the width direction more than the virtual reference line Q, even if the second pointed portions 200A and 200B are pressed against the pressed portion, the brush hairs 41 are less likely to interfere with the pressed portion and its periphery, and a good feeling of use can be obtained. In addition, the first arc connection portions 18A and 18B have a more acute angle of the surface forming the ridge line R1 than the second arc connection portions 19A and 19B and the side edge portions 28A and 28B of the elliptical portion 21 of the handle 2. Therefore, while considering the ease of gripping the handle 2 and the interference with the head of the head base 30, the effect of the kassatsu method can be enhanced.

[0046] In addition, since the head base 30 and the handle 2 are made of bamboo, the hairbrush 1 can be made relatively lightweight. Thereby, the feeling of use of brushing and massage can be enhanced. In addition, since the handle 2 is formed thin so that the thickness dimension is smaller than the width dimension, the ease of gripping when brushing in the width direction can be enhanced. In addition, the handle 2 and the head base 30 are configured such that thin bamboo materials are laminated in the width direction to form an integral laminate. Therefore, even if the head base 30 and the handle 2 are thin, the rigidity in the thickness direction can be enhanced compared to the case where they are laminated in the thickness direction. As a result, the force applied by hand can be easily transmitted to the pressed portion, and the massage function can be further enhanced.

[0047] The first tip 100 is sharp such that the front surface 15 and the back surface 16 form a ridge line R1, and is also sharp such that one side surface 101 on one side and the other side surface 102 on the other side form a ridge line R2 with respect to the axis P. Therefore, the first tip 100 can be sharpened with a simple configuration. In particular, when the thin handle 2 is adopted as in this embodiment, the first tip 100 can be easily sharpened. In addition, since the second tips 200A and 200B have convex portions that are arcuate when viewed in the thickness direction, even if the second tips 200A and 200B accidentally interfere with the user's head during brushing, the discomfort of the user can be suppressed. Thereby, the usability during brushing and massaging can be enhanced. In addition, since the head base 30 has second arc connection portions 19A and 19B that connect the second tips 200A and 200B and the head tip portion 31 side of the head base 30 so as to be concave in an arc shape when viewed in the thickness direction, compared with the case where the second tips 200A and 200B and the head tip portion 31 side of the head base 30 are connected linearly, while suppressing the width dimension of the head base 30 to be small, the second tips 200A and 200B can be made sharper.

[0048] In addition, since the head tip portion 31 of the head base 30 is formed to be convex in an arc shape when viewed in the thickness direction, even if the head tip portion 31 accidentally interferes with the user's head or hand during brushing, the discomfort of the user can be suppressed. Thereby, the usability during brushing and massaging can be enhanced. In addition, since the base communication hole 37 communicating with the mounting recess 34 opens on the front surface 15 of the head tip portion 31 of the head base 30, compared with the case where the base communication hole 37 is formed at the tip 3c or the outer peripheral end (ridge line R1) of the head base 30, it is difficult for the base communication hole 37 to come into contact with the user's head or hand. Thereby, the usability during brushing and massaging can be enhanced.

[0049] It should be noted that the present disclosure is not limited to the above-described embodiments, and can be implemented in various forms without departing from the gist of the present disclosure. For example, although the hairbrush 1 employs a thin handle 2, alternatively, an axial handle 2 such as a cylindrical or polygonal prism shape may be adopted. In this case, the first pointed portion 100 may be sharpened into a conical shape or a polygonal pyramid shape. Also, although the second pointed portions 200A and 200B are formed at both side edges 38A and 38B of the head base 30, they may be formed on only one side. Further, the angles and sizes at which the first pointed portion 100 and the second pointed portions 200A and 200B are sharpened are not limited to the above-described embodiment and can be appropriately changed. Also, although the brush bristles 41 employ pin members, animal hairs or nylon hairs may be provided over the entire surface of the rubber seat 45, or a plurality of these formed into tufts may be provided at intervals. Further, the rubber seat 45 may be omitted and the brush bristles 41 may be directly provided on the head base 30. Also, although the head base 30 and the handle 2 are formed of a bamboo laminate, they may be formed of wood, synthetic resin, or the like. Also, the head base 30 and the handle 2 may be configured such that separate members are connected without being integrally formed. Also, although the head tip portion 31 of the head base 30 is formed to be convex in an arc shape when viewed from the thickness direction, it may be formed, for example, to be angular in a polygonal shape. Also, although the base communication hole 37 is formed in the main surface 15 of the head tip portion 31, it may be formed at other positions of the head base 30. Also, although the formation of the base communication hole 37 and the sheet communication hole 49 has been described, a configuration in which only one of them is formed may be employed. Further, a configuration in which neither the base communication hole 37 nor the sheet communication hole 49 is formed may be employed. Also, although the ridge line R1 is formed over the entire circumference of the outer peripheral end portion 12, it may be formed only in a part of the circumferential direction. Also, the position of the ridge line R1 may be formed closer to one side or the other side in the thickness direction. Also, although the brush bristle assembly 40 combining the brush bristles 41 and the rubber seat 45 is used, a brush bristle structure in which the brush bristles 41 and the rubber seat 45 are integrally molded may be used.
