  The present invention is a method in which heat generated by the operation of a solenoid that is a drive source of the ball ball is cut off by a thermal protector in the prior art, but this method has a problem in terms of safety and use, and the drive source It is characterized in that a metal chassis is interposed between the solenoid and the covering material such as a foam surrounding the solenoid.

  Embodiments of the present invention will be described below with reference to the drawings. In the following description, parts common to those in the conventional example shown in FIG.

  FIG. 2 is a perspective view showing the surrounding structure of the Tataka ball, which is the basic structure of the massage device of the present invention. In the figure, 1 is a ball, 2 is a solenoid, 2a is its plunger, 3 is a coil for generating a magnetic field, 4 is a solenoid frame, 5 is a thermal protector, and 6 is a urethane foam cover. When actually used as a massage device, this structure is used as one element, and a plurality of these are used and housed inside a cover material or the like to be used as a single device. As in the conventional example, the surface ball 1 has a spherical top surface and a flat bottom surface. However, the surface ball used in the present invention is not limited to this shape. The shape can be adopted.

  The foamed urethane cover 6 encloses the entire solenoid 2 that is driven by the supply of phase-controlled electric power, etc., and uses the cushioning and heat insulation properties to generate heat from the solenoid 2 when using a massager. It is the same as the conventional example in that it is difficult to convey to the user.

However, unlike the conventional example, the metal chassis 10 is interposed between the solenoid 2 and the urethane foam cover 6. this is,
(1) By interposing the metal chassis 10 having a high thermal conductivity, the heat from the solenoid 2 is first efficiently transmitted to the entire metal chassis 10,
(2) Since the entire metal chassis 10 becomes a heat source, the heat dissipation surface is significantly wider than the conventional example, and the cooling effect is enhanced.
(3) The cooling effect is further enhanced by providing the foamed urethane cover 6 with a large number of open holes 11 that connect the metal chassis 10 and an outer cover (not shown) made of synthetic leather as an exterior material.

  In the illustrated example, four open holes 11 are drawn in the vertical direction and one in the horizontal direction. However, this is merely an example, and the present invention is limited to this example. There is no need to select the optimum number, position, opening area, etc. in terms of design. Moreover, it is not necessary to open directly with respect to the metal chassis 10 and the jacket cover which is an exterior material, respectively, and the structure which has a bottom part like a hole may be sufficient. In short, it is only necessary to have an opening and a hole as a path for releasing heat to the outside, and the present invention is not limited to the illustrated example.

In this embodiment,
(1) As a result of the metal chassis 10 being interposed, the solenoid frame 4 is fixed to a rigid body (screwed in the illustrated example), and the tapping force of the ball 1 is increased.
(2) When power is supplied as usual, the power is too strong, so a method of adjusting the strength by suppressing the power supply has been adopted. However, this leads to power saving and the heat generation of the solenoid 2 as a result. It could be further reduced.
(3) Further, conventionally, when used for a certain period of time, due to the restriction of the temperature rise of the solenoid 2, the use time up to that time or the rest time longer than that was required. However, in this embodiment, the restriction on temperature is eliminated. Long continuous use is possible.
