First, the rolling massage part 20a will be described in detail with reference to FIGS. The rolling massage unit 20a is a first massage attachment, and can roll on a user's desired skin surface in response to driving of the electric motor 103 to give a pulsed stimulus to the skin surface. it can.

As shown in FIGS. 2 and 3, the rolling massage unit 20 a includes one rotating disk 210, three rotating shafts 213, three massage roller units 220, and three cap nuts 230. In FIG. 2, two rotating shafts 213, massage roller units 220, and cap nuts 230 are illustrated for easy viewing of the drawing.
As shown in FIG. 2, the rotating disk 210 is a base body formed in a columnar shape or a disk shape. The turntable 210 is fixed to the distal end side of the transmission shaft 106a and disposed in the accommodation space 107c, and rotates integrally with the transmission shaft 106a corresponding to the drive of the electric motor 103.
The turntable 210 has an upper surface 210a facing the lower cover 107, a lower surface 210b opposite to the upper surface 210a, and a side surface 210c connecting the upper surface 210a and the lower surface 210b.

In the turntable 210, a transmission shaft mounting hole 211 into which the transmission shaft 106a is inserted and removed freely and a plurality of rotation shaft insertion holes 212 into which the plurality of rotation shafts 213 can be inserted are formed.
The transmission shaft mounting hole 211 is formed in a shape and size that allows the transmission shaft 106a to be inserted, and is provided substantially vertically from a substantially central portion of the upper surface 210a to a substantially central portion of the lower surface 210b. A groove 211a corresponding to the thread 106b at the tip of the transmission shaft 106a is formed on the side wall near the bottom of the transmission shaft mounting hole 211. By fitting the thread 106b into the groove 211a, the turntable 210 is fitted. Can be stably fixed to the transmission shaft 106a. This prevents the turntable 210 from falling off the lower part of the housing 100. The shape of the groove 211a may be variously changed according to the shape of the tip of the transmission shaft 106a. For example, when a flange-shaped convex portion is formed at the tip of the transmission shaft 106a, a concave portion corresponding to the convex portion may be formed on the side surface near the bottom of the transmission shaft mounting hole 211.

The plurality of rotation shaft insertion holes 212 are each formed in a shape and size into which one end of the rotation shaft 213 can be inserted, and are formed at predetermined intervals in the circumferential direction of the side surface 210c. As shown in FIG. 3, the rotation shaft insertion holes 212 are formed such that, as an example, when the lower surface 210 b is viewed from the front, an interval of 120 degrees is opened.
As shown in FIG. 2, the rotation shaft 213 is a rod-shaped member, and functions as a rotation shaft of the massage roller unit 220 by pivotally supporting the massage roller unit 220.
The rotating shaft 213 is provided so that one end thereof is inserted into the rotating shaft insertion hole 212 and extends outward from the side surface 210 c of the rotating disk 210.

Further, the rotation shaft 213 may be formed integrally with the turntable 210.

A thread 213a for locking the cap nut 230 is formed at the other end of the rotating shaft 213. By locking the cap nut 230 to the rotating shaft 213, it is possible to prevent the massage roller unit 220 supported by the rotating shaft 213 and attached to the rotating plate 210 from falling off the rotating plate 210.
The massage roller unit 220 includes a pair of rollers 220a and 220b having a gear shape.
The roller 220a includes an inner ring 221a and an outer ring 226a provided so as to cover the outer edge of the inner ring 221a.
The inner ring 221a is a columnar or disk-shaped member having an upper surface 222a, a lower surface 223a opposite to the upper surface 222a, and a through hole 225a. The inner ring 221a is preferably formed of rubber or plastic. The through hole 225a is a hole that penetrates from the upper surface 222a to the lower surface 223a, and is provided at a substantially central portion of the inner ring 221a. The through hole 225a has a size and a shape into which the rotating shaft 213 can be inserted. The roller 220a can be attached to the rotating shaft 213 by the through hole 225a.

The outer ring 226a is desirably formed of rubber or foamed plastic so as to have appropriate elasticity. The outer ring 226a has a plurality of barbs 227a projecting in a gear shape along the outer peripheral surface for stimulating the skin surface of the user.
The dimension of the outer ring 226a, the dimension of the barbs 227a, and the number of installation are not particularly limited, and predetermined numerical values and numbers can be appropriately employed. For example, as the diameter of the outer ring 226a (the length from the tip of one barb 227a to the other barb 227a on the opposite side), an arbitrary numerical value in the range of 4 cm to 5 cm may be adopted as appropriate (for example, the diameter is 4.5 cm) ). For example, an arbitrary numerical value may be set as appropriate in the range of 0.6 to 1.0 cm (for example, 0.8 cm) as the height of each barb 227a. The number of barbs 227a can be set to 13, for example.

The roller 220b is configured similarly to the roller 220a, and includes an inner ring 221b and an outer ring 226b corresponding to the inner ring 221a and the outer ring 226a included in the roller 220a, respectively. The inner ring 221b includes an upper surface 222b, a lower surface 223b, and a through hole 225b corresponding to the upper surface 222a, the lower surface 223a, and the through hole 225a. The outer ring 226b includes barbs 227b corresponding to the barbs 227a.
As a result, as shown in FIG. 3, the massage roller unit 220 configured as described above has an opening at the lower end of the casing 100 so that an interval of 120 degrees is opened when the lower surface 210 b of the turntable 210 is viewed from the front. Arranged in the opening.

(How to use the rolling massager 20a)
The usage method and effect when the rolling massage part 20a having the above configuration is mounted on the electric roller massage machine 1 will be described. When the user turns ON / OFF the switch 104, the drive of the electric motor 103 (rotation of the main shaft 103a) is turned ON / OFF. The rotational speed of the main shaft 103 a is converted to an optimum speed by the gear box 106 and transmitted to the rotating disk 210. As a result, the entire rolling massage portion 20 a rotates at the lower end of the housing 100 coaxially with the electric motor 103 and relative to the housing 100. That is, the massage roller unit 220 rotates and moves along the opening edge at the bottom of the housing 100 (see the arrow in FIG. 3).

  When the drive of the electric motor 103 is in the ON state, the user grips the gripping part 100a and makes the barbs 227a and 227b of the massage roller unit 220 contact the skin surface of the user, thereby using the barbs 227a and 227b. Due to the friction with the person's skin, the massage roller unit 220 supported by the rotation shaft 213 rolls on the skin surface while rotating as indicated by the arrow in FIG. By the barbs 227a and 227b rolling on the skin surface, a pulse-like stimulus can be given (that is, tapped) to the skin surface. And a massage effect can be given to the skin surface by this pulse-like stimulus.

Next, the ball massage unit 20b will be described in detail with reference to FIGS. The ball massage unit 20b is a second massage attachment, and is detachably attached to the lower end of the housing 100 in the same manner as the rolling massage unit 20a, and corresponds to the user's desired skin corresponding to the driving of the electric motor 103. It is a stimulus applying section that rolls on the surface and gives a continuous and cool stimulus to the skin surface.
As shown in FIG. 4, the ball massage unit 20 b includes one rotating disk 310 and three massage balls 320.
The turntable 310 is disposed in the accommodation space 107c, is fixed to the transmission shaft 106a, and rotates integrally with the transmission shaft 106a corresponding to the drive of the electric motor 103.

The turntable 310 is a base body formed in a substantially cylindrical shape having a flange portion 311 at the lower end. The turntable 310 has an upper surface 310 a that faces the lower cover 107, and a lower surface 310 b that is a surface opposite to the upper surface 310 a and includes the lower surface of the flange portion 311.
In the turntable 310, a transmission shaft mounting hole 312 is formed, corresponding to the transmission shaft mounting hole 211 of FIG.
The flange portion 311 protrudes in a direction orthogonal to the vertical direction of the turntable 310. The flange portion 311 has a massage ball holding portion 311a for holding the massage ball 320 rotatably. The massage ball holding portion 311a has a substantially trapezoidal appearance, and protrudes from the lower surface 310b in a direction opposite to the upper surface 310a.

The massage ball holding portion 311a is formed so as to be longer than the radius t in the cross section of the massage ball 320 (see t1 in the figure) so that the massage ball 320 does not fall off, and its tip portion has a “caulking structure”. It is desirable.
As shown in FIG. 5, the massage ball holding portions 311a are formed so as to be spaced from each other by 120 degrees in the circumferential direction of the lower surface 310b.
As shown in FIG. 4, the transmission shaft mounting hole 312 is formed in a shape and size that allows the transmission shaft 106a to be inserted, and is provided substantially vertically from a substantially central portion of the upper surface 310a to a substantially central portion of the lower surface 310b. It is done. A groove 312a corresponding to the thread 106b at the tip of the transmission shaft 106a is formed on the side wall near the bottom of the transmission shaft mounting hole 312. By fitting the screw thread 106b into the groove 312a, the rotary disk 310 is fitted. Can be fixed to the transmission shaft 106a. This prevents the ball massage part 20b from falling off the lower part of the housing 100.

  The massage ball 320 is a stimulus imparting body, for example, a metal sphere. The massage ball 320 rolls smoothly on the user's skin surface. The massage ball 320 can also be formed of rubber or foamed plastic.

(How to use the ball massage part 20b)
A method of use and effects when the ball massage portion 20b having the above configuration is mounted on the electric roller massage machine 1 will be described. When the user turns ON / OFF the switch 104, the drive of the electric motor 103 (rotation of the main shaft 103a) is turned ON / OFF. The rotational speed of the main shaft 103 a is converted to an optimal speed by the gear box 106 and transmitted to the rotating disk 310. As a result, the entire rolling massage portion 20 a rotates at the lower end of the housing 100 coaxially with the electric motor 103 and relative to the housing 100.
That is, the massage ball 320 held by the massage ball holder 311a rotates and moves along the opening edge at the bottom of the housing 100 (see the arrow in FIG. 5).

  Thus, when the drive of the electric motor 103 is in the ON state, the user grips the gripping part 100a and brings the massage ball 320 into contact with the user's skin surface. Due to this friction, the massage ball 320 rolls smoothly on the skin surface. The skin surface can be massaged by the massage ball 320 that rolls on the skin surface. When the massage ball 320 is made of metal, when the massage ball 320 comes into contact with the skin surface, the heat of the skin surface moves to the massage ball 320 and locally lowers the body temperature of the skin. As a result, the effect of tightening the skin can be obtained.

According to the electric roller massage machine 1 according to the present invention, the user can easily replace the rolling massage part 20a and the ball massage part 20b described above at an arbitrary timing, with different stimulations. You can get a sense.
Since the rolling massage part 20a and the ball massage part 20b have different ways of giving stimulation to the skin surface, it is possible to prevent the user from getting used to the stimulation. This can prevent the user from gradually using the massager.

The electric roller massage machine 1 according to one aspect of the present invention has been described above, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention. is there.
For example, in the above-mentioned embodiment, the massage part 20 was comprised from the rolling massage part 20a or the ball massage part 20b. This massage part 20 can also be set as the structure provided with the other massage means replaced with the rolling massage part 20a or the ball massage part 20b.
