Will be. Since the surgical element 15 is rotatably supported with respect to the rotation support member 23 (about the second axis X2), depending on the load (friction with the scalp or hair that is in contact with the protrusion 14). Thus, for example, it is possible to rotate (turn around) the first axis X1 while maintaining the positional relationship of the protrusion 14 with respect to the second axis X2 as seen from the first axis X1 direction. Yes. Therefore, depending on the load (friction with the scalp and hair, etc.), the hair is entangled with the surgical element based on the movement in which each protrusion 14 simply rotates around the first axis X1 (each with a respective radius). It is possible to avoid such a phenomenon.

Next, characteristic effects of the above embodiment will be described below.
(1) Since the main body housing 11 is provided with the cover 31 (cover main body portion 31 b) that covers the periphery of the output shaft 12 protruding from the main body housing 11, it is possible to reduce the tangling of hair to the output shaft 12. it can.

  (2) The surgical element 15 includes a rotating member 21 provided so as to be rotatable with respect to the output shaft 12 about the second axis X2 that is shifted from the first axis X1 that is the center of the output shaft 12, and the first shaft And a plurality of protrusions 14 provided on the rotating member 21 so as to be arranged at positions deviated from X1 (positions at an equal distance from the second axis X2). Therefore, the scalp can be cared for by moving the treatment element 15 (group of the plurality of protrusions 14) over a wide range without moving the main body housing 11.

  (3) The cover 31 is a rotating member cover portion 31c that covers at least part of the periphery of the rotating member 21 (the lower side of the tube portion 21b) while allowing rotation (circulation) of the treatment element 15 about the first axis X1. Therefore, it is possible to reduce the entry of the hair to the periphery of the output shaft 12, and to further reduce the tangling of the hair to the output shaft 12.

The above embodiment may be modified as follows.
In the above embodiment, the cover 31 has the rotating member cover portion 31c that covers the lower side of the cylindrical portion 21b that is a part of the periphery of the rotating member 21, but the present invention is not limited to this. For example, FIG. As shown in FIG. 4, the rotating member 21 may be changed to have a rotating member cover portion 31g that covers the entire periphery of the rotating member 21 (in this example, the base end portion of the protrusion 14). If it does in this way, it can further reduce that hair penetrates into the circumference of output shaft 12 by rotation member cover part 31g, and can further reduce that hair gets entangled in output shaft 12 by extension. Moreover, you may change into the cover which does not have the rotation member cover parts 31c and 31g which cover the circumference | surroundings of the rotation member 21. FIG.

  The rotating member cover portions 31c and 31g of the above embodiment and other examples are deformable following deformable bodies that partition the outside and the output shaft 12 side while following the rotation of the treatment element 15 about the first axis X1. You may change so that it may have.

  For example, as shown in FIG. 3, a cloth as a follow-up deformable body provided so as to cover other than the plurality of protrusions 14 in the opening 31 e of the rotating member cover portion 31 g in the scalp care device 1 of the other example (see FIG. 2). The member 41 may be provided. The cloth member 41 is provided with a hole at a position corresponding to the protrusion 14 so that the protrusion 14 penetrates the hole. The cloth member 41 is formed and provided with a size that does not inhibit (allow) the rotation of the treatment element 15 about the first axis X1.

  In this case, the rotating member cover portion 31g has the deformable cloth member 41 that separates the outside and the output shaft 12 side while following the rotation of the treatment element 15 about the first axis X1. Intrusion to the periphery of the output shaft 12 is prevented, and as a result, hair is prevented from being entangled with the output shaft 12.

  For example, as shown in FIGS. 4 and 5, the follower deformable body may be changed to a bellows-shaped bellows member 42 made of an elastic body. Specifically, the scalp care device 1 of this example includes a rotating member cover portion that covers the periphery of the rotating member 21 on the cover body portion 31h that extends in a cylindrical shape so as to cover the exposed periphery (radially outer side) of the output shaft 12. The bellows member 42 as a deformable follow-up deformable body that partitions the outside and the output shaft 12 side while following the rotation around the first axis X1 of the treatment element 15 is provided. One end opening of the bellows member 42 is fixed to the opening 31 i of the cover main body 31 h, and the other end opening is externally fitted to the cylindrical portion 21 b of the rotating member 21 of the treatment element 15.

  Even in this case, the rotating member cover portion has the deformable bellows member 42 that partitions the outside and the output shaft 12 side while following the rotation around the first axis X1 of the treatment element 15, so that the hair is Intrusion to the periphery of the output shaft 12 is prevented, and as a result, hair is prevented from being tangled with the output shaft 12. Further, since the follower deformable body is a bellows-shaped bellows member 42 made of an elastic body, the follower deformable body can smoothly follow the rotation around the first axis X1 of the treatment element 15, and for example, the follower deformable body can be a cloth member. As in the case of FIG. 3 (see FIG. 3), irregular and large slack does not occur.

  Further, for example, as shown in FIGS. 6 and 7, the follower deformable body 15 maintains the state in which the positional relationship of the projection 14 with respect to the second axis X2 does not change when viewed from the first axis X1 direction. May be changed to the bellows member 43 connected to the treatment element 15 so as to rotate (circulate) around the first axis X1. Specifically, in this example, the bellows member 43 is provided so as to cover other than the plurality of projections 14, and each projection 14 passes through a hole 43 a (see FIG. 7) formed in the bellows member 43, and each of the bellows members 43. By engaging with the member 43, the state in which the positional relationship of the protrusion 14 with respect to the second axis X2 does not change when viewed from the first axis X1 direction is maintained. That is, in this example, the bellows member 43 made of an elastic body allows the movement (rotation) of the surgical element 15 about the first axis X1, but resists the rotation of the surgical element 15 that twists itself. Thus, the positional relationship of the protrusion 14 with respect to the second axis X2 is prevented from changing. In this example (see FIGS. 6 and 7), a bellows is provided in the opening 31k of the rotating member cover portion 31j extending from the cover main body portion 31b so as to cover a part of the periphery (cylinder portion 21b) of the rotating member 21. One end opening of the member 43 is fixed.

  Even in this case, the rotating member cover portion 31j has the deformable bellows member 43 that partitions the outside and the output shaft 12 side while following the rotation of the treatment element 15 about the first axis X1. Is prevented from entering the periphery of the output shaft 12 and, in turn, hair is prevented from being tangled with the output shaft 12. Further, since the follower deformable body is a bellows-shaped bellows member 43 made of an elastic body, the follower deformable body can smoothly follow the rotation around the first axis X1 of the treatment element 15, and for example, the follower deformable body can be a cloth member. As in the case of FIG. 3 (see FIG. 3), irregular and large slack does not occur.

  In this example, the bellows member 43 is such that the surgical element 15 is centered on the first axis X1 while the positional relationship of the projection 14 with respect to the second axis X2 remains unchanged as viewed from the first axis X1 direction. It is connected to the treatment element 15 so as to rotate (circulate). Therefore, it is possible to avoid the phenomenon that the hair is entangled with the treatment element 15 based on the movement in which each protrusion 14 simply rotates around the first axis X1 (each with a respective radius). Further, in this example, the bellows member 43 is provided so as to cover other than the plurality of projections 14, and each projection 14 penetrates the bellows member 43 and engages with the bellows member 43. A state in which the positional relationship of the protrusion 14 with respect to the second axis X2 does not change when viewed from the direction of the axis X1 is maintained. Therefore, the above-described effects can be obtained with a simple configuration without adding a separately engaged configuration (special shape, adhesive, or the like).

  In the above embodiment, the treatment element 15 is provided so as to be rotatable about the second axis X2 that is shifted from the first axis X1 that is the center of the output shaft 12. A structure that rotates integrally with the shaft 12 may be used.
