Moreover, as shown in FIG. 4, the pressure suppression part 82 is comprised so that length H2 from the vertex of the major axis direction of the pressure suppression part 82 to the frame part 81 upper surface 81c may be 8.5 mm. Thus, it is preferable that the pressure suppression part 82 is comprised low with respect to the treatment element 67e.

Next, an operation example (action) of the scalp care device 20 of the present embodiment will be described.
First, the operation switch 23 provided in the apparatus main body 21 is pushed by the user, so that the motor 32 is rotationally driven, and the driving force thereof is converted by the conversion mechanism 33 of the drive unit 31 and the first and second driver elements 40a and 40b. Converted to reciprocating linear motion. And the movable treatment part 67 attached to the treatment part mounting parts 41 and 42 of the 1st and 2nd driver elements 40a and 40b is reciprocated.

  When the user presses the movable head 65 having the movable treatment portion 67 against the scalp, the treatment element 67e of the movable treatment portion 67 reciprocated as shown in FIG. 19A slides on the scalp th. Thus, dirt and sebum on the surface of the scalp th are scraped off and the scalp th can be cleaned. In addition, in FIG. 19 (a)-(c), since the treatment head is simplified, the detailed shape is different from other drawings.

  At this time, as shown in FIG. 19B, with only a single type of treatment element 67e as in the conventional configuration, the user strongly presses the treatment part against the scalp, so that the treatment element 67e of the movable treatment part 67 is attached to the scalp th When the frictional force generated when sliding on the surface increases, the surgical element 67e may be bent. Thereby, the driving force of the reciprocating operation is not transmitted to the distal end of the treatment element 67e, and there is a possibility that the treatment element 67e cannot slide on the scalp th.

  Therefore, in the scalp care device 20 of the present embodiment, as shown in FIG. 19C, the scalp care device 67 e of the movable treatment section 67 is made to have high rigidity with respect to the treatment element 67 e of the movable treatment section 67. A pressure suppression portion 82 having a lower height is provided.

  Thereby, the pressure which contacts the scalp is distributed by the movable treatment part 67 and the pressure suppression part 82 by making the pressure suppression part 82 contact the scalp before sliding of the front-end | tip of a treatment element stops with frictional force. . For this reason, the pressure which contacts with the scalp of the movable treatment part 67 is relieved, and the frictional force which arises when the front-end | tip of the treatment element 67e slides on the scalp is relieved, so that the treatment element 67e of the movable treatment part 67 becomes a scalp. And is cleaned.

  In addition, when a load is applied to the movable treatment portion 67 of the movable head 65 in the drive state from the vertical direction Y or the front-rear direction Z that intersects the drive direction, the guide rail 55 and The engaging recess 66 c as a slide part regulates the displacement of the movable treatment part 67.

  As a result, the displacement of the drive unit 31 is suppressed, the drive unit is prevented from coming into contact with each peripheral component member, and noise generation and vibration generation are suppressed. Further, by providing a gap G between the guide rail 55 and the base 66, contact with the guide rail 55 due to displacement in the vertical direction (vertical direction Y) with respect to the lower surface 66a of the base 66 is prevented.

The scalp care device of the present embodiment has the following effects.
(1) When a load is applied to the movable treatment section 67 of the movable head 65 from the direction intersecting the drive direction, the displacement of the base 66 in the direction intersecting the drive direction is suppressed, and the drive section connected to the base 66 It is also possible to suppress displacement in a direction that intersects the driving direction of 31. For this reason, it can prevent that the drive part 31 contacts a surrounding structural member, and noise generation and vibration generation | occurrence | production are suppressed. At this time, since the movement in the driving direction is not restricted, the scalp washing performance can be maintained.

(2) The displacement toward the drive unit 31 with respect to the load applied to the movable treatment unit 67 can be restricted on the lower surface 66 a side of the base 66.
(3) Even if the base 66 is reciprocated, the positional relationship between the guide rail 55 constituting the restricting portion and the engaging recess 66c as the slide portion is constant, and the drive is performed regardless of the relative position of the reciprocating drive. The displacement of the part 31 can be stably suppressed, and the generation of vibration and noise can be further suppressed.

(4) Contact between the lower surface 66a of the base 66 and the guide rail 55 can be prevented, and generation of vibration and noise can be further suppressed.
