When the action protrusion 83 of these treatment elements 81a-81d is brought into contact with the scalp, the user's scalp moves in accordance with the action of the action protrusion 83 . Thus, care (massage) the scalp. At this time, each treatment member 81a-81d operates so that the scalp may move in one direction according to the operation|movement of the gears 41-46 and the arrangement|positioning relationship of the rotation base 55. As shown in FIG.

Here, the rotation operation|movement of each treatment element 81a-81d which the scalp care apparatus 10 has is demonstrated in detail mainly using FIG. In addition, Fig. 9 is a plan view when the scalp care device 10 is seen from the lower side. And, in FIG. 9, the direction perpendicular to the paper surface corresponds to the up-down direction, the left-right direction in FIG. The front-back direction will be described.

As shown in FIGS. 9 and 10 , the four connecting shafts 47 are arranged at the vertices of a substantially square when viewed from below. Each treatment element 81a-81d is connected to the corresponding connection shaft 47 via the rotation base 55, the output shaft 56, and the treatment element base 71 (FIG. 8), respectively. As shown in FIG. 9, the treatment element 81a, 81b adjacent to the front-back direction rotates counterclockwise. At this time, the treatment elements 81a, 81b are shifted by 180 degrees from each other by the center P1 (output shaft 56) of the treatment element base portion 82 of the treatment element 81a and the center P2 (output shaft 56) of the treatment element base portion 82 of the treatment element 81b. The phase of the rotation. On the other hand, the treatment elements 81c, 81d rotate clockwise. The same applies to the two treatment elements 81c and 81d, so that the center P3 (output shaft 56) of the treatment element base 82 of the treatment element 81c and the center P4 (output shaft 56) of the treatment element base 82 of the treatment element 81d are staggered from each other. 180 degree phase rotation. Therefore, treatment elements 81a, 81c (treatment elements 81b, 81d) adjacent to the left-right direction rotate so that respective centers P1, P3 (centers P2, P4) are line-symmetrical to each other with respect to the vertical bisector L.

In this structure, when each treatment member 81a-81d rotates 270 degrees from the position shown in FIG. The furthest state in the forward-backward direction. When each treatment element 81a-81d rotates 90 degrees from this state, as shown in FIG. 9, treatment element 81a, 81c will be closest to the left-right direction. Thereby, the operation|work of kneading a scalp is performed between the treatment protrusion 83 of the treatment element 81a, 81c. At this time, the scalp sandwiched between the treatment elements 81a, 81c moves in the rotation direction of the treatment elements 81a, 81c.

When each treatment element 81a-81d further rotates 90 degrees from this state, the centers P1, P2 of the treatment element 81a, 81b which rotated in the same direction are closest to each other at the same timing. At this time, the treatment element 81a, 81b rotates so as to shift from each other at positions close to each other in a partial view. Therefore, when the treatment elements 81a and 81b approach the scalp at the same timing, and when the treatment elements 81a and 81b deviate from each other from this state, twisting motion is given to the scalp. In this way, by bringing the treatment elements 81a, 81b that clamp and twist the scalp into contact with the scalp, the user's scalp can be effectively operated in accordance with the movement of the treatment elements 81a, 81b, and care (massage) can be performed. Moreover, treatment element 81c, 81d performs the operation|movement which clamps and twists to scalp similarly to treatment element 81a, 81b.

When each treatment member 81a to 81d is further rotated by 90 degrees from this state (rotated by 180 degrees from the state of FIG. 9 ), the treatment members 81b and 81d are closest to each other in the left and right direction, and the scalp is held between the treatment members 81b and 81d for rubbing. . That is, the action of kneading the scalp is performed between the treatment protrusions 83 of the treatment elements 81a, 81c. At this time, as described above, the scalp sandwiched between the treatment elements 81a, 81c moves to the treatment element 81b, 81d side by the operation of these treatment elements 81a, 81c. Therefore, the kneading motion of the treatment elements 81b, 81d and the treatment elements 81a, 81c continuously kneads the user's scalp.

In this way, in the example shown in FIG. 9 , different types of actions can be applied to the scalp according to the rotation angles of the respective treatment elements 81 a to 81 d (centers P1 to P4 ), thereby contributing to the improvement of the scalp care effect.

In the scalp care device 10 comprised as mentioned above, treatment elements 81a-81d are integrally formed with the cover part 61 as mentioned above.

In addition, a plurality of bar portions 64 connecting the outer frame portions 63 of the head base portion 62 are provided on the head base portion 62 . Therefore, the rigidity of the head base part 62 can be improved. Thereby, the working head part 12 can be attached and detached easily with respect to the apparatus main body part 11. As shown in FIG. Moreover, since the cylindrical engaging part 65a provided in the bar part 64 is connected with the protrusion part 61b of the cover part 61, it can prevent that the cover part 61 floats up and down with respect to the head base part 62. Therefore, treatment element 81a-81d can be operated stably.

Moreover, the treatment element base 71 with rigidity higher than each treatment element 81a-81d (operation protrusion 83) is provided in the opposite surface side (upper in the up-down direction) of the treatment element base part 82 of each treatment element 81a-81d. Thereby, the driving force of each output shaft 56 can be preferably transmitted to the treatment elements 81a-81d via the highly rigid treatment element base 71. In addition, since the treatment element base 71 with high rigidity is interposed between the treatment elements 81a to 81d and the output shaft 56, compared with the case where the treatment elements 81a to 81d are directly connected to the output shaft 56, it is possible to suppress damage caused by abrasion. Waiting to reduce lifespan.

Moreover, the treatment element 81a-81d has the fitting convex part 82a as an engaging part which engages with the treatment element base 71 at least in the operation direction of the treatment element 81a-81d. Therefore, the treatment element 81a-81d and the treatment element base 71 can be connected more reliably. Thereby, the rigidity of the proximal end side of the treatment elements 81a-81d (the action protrusion 83) can be improved, and the shape of the treatment elements 81a-81d (the action protrusion 83) can be maintained preferably.
