  As shown in FIG. 2, the treatment device 20 of the present embodiment has a configuration in which the distal end portion of the support member 32 and a part of the heat dissipation member 60 overlap in the width direction. For this reason, the dimension in the width direction (hereinafter referred to as “width dimension HB”) from the support member 32 to the kneading ball 40 of the treatment apparatus 20 is the same as the dimension in the width direction of the heat radiating member 60 and the dimension in the width direction of the kneading ball 40. It will be. That is, the width dimension HB of the treatment apparatus 20 of this embodiment is smaller than the width dimension HX of the treatment apparatus 200 of the comparative example.

  In the treatment devices 20, 200, the distance between the one kneading ball mechanism 30, 250 and the other kneading ball mechanism 30, 250 is changed by the width driving mechanism 23. And when one kneading ball mechanism 30 and 250 and the other kneading ball mechanism 30 and 250 are mutually separated most, a pair of support members 32 and 240 have predetermined dimension HA in the width direction. At this time, in the treatment apparatus 200 (FIG. 7) of the comparative example, one kneading ball mechanism 250 and the other kneading ball mechanism 250 have a predetermined dimension HY in the width direction. Moreover, in the treatment apparatus 20 (FIG. 2) of this embodiment, one kneading ball mechanism 30 and the other kneading ball mechanism 30 have a predetermined dimension HC in the width direction.

  And in the treatment apparatus 200 (FIG. 7) of the comparative example, the maximum amount of the relative movement amount of each kneading ball mechanism 250 by the width driving mechanism 23 is a predetermined dimension HY. On the other hand, in the treatment apparatus 20 (FIG. 2) of the present embodiment, the maximum amount of relative movement of each kneading ball mechanism 30 by the width driving mechanism 23 is a predetermined dimension HC. That is, the movement range of each kneading ball mechanism 30 by the width driving mechanism 23 of the present embodiment is larger than the movement range of each kneading ball mechanism 250 by the width driving mechanism 23 of the comparative example.

  For this reason, the treatment device 20 (FIG. 2) of the present embodiment uses the kneading balls 40 for the user with a large shoulder width compared to the case where the treatment device 200 (FIG. 7) of the comparative example is used. Can be performed at an appropriate position.

(Effect of embodiment)
According to the massage machine 1 of this embodiment, the following effects are acquired.
(1) The support member 32 has a function as a cover that covers a part of the heater 51. That is, a cover that covers the heater 51 is constituted by the heat dissipation member 60 and the support member 32. According to this configuration, a member corresponding to the second cover member 132 in the treatment apparatus 100 of FIG. For this reason, the bolt 133 which fastens the 1st cover member 131 and the 2nd cover member 132 of the treatment apparatus 100 becomes unnecessary. Thereby, compared with the treatment apparatus 100, the number of parts decreases. That is, the above-described configuration relating to the support member 32 contributes to a reduction in the number of parts of the massage machine 1.

  (2) The heat application portion 62 of the heat radiating member 60 includes an intermediate portion 62A that covers the distal end surface 32A of the support member 32, and an outer portion 62C that is positioned outward in the width direction relative to the intermediate portion 62A. . According to this configuration, the cover 11B is less likely to contact the tip portion of the support member 32 as the outer portion 62C of the heat application portion 62 contacts the cover 11B. For this reason, the cover 11 </ b> B is prevented from being damaged by “burr” or “burl” of the support member 32. Each part of the support member 32 may be formed with at least one of “burr” and “burr” in the manufacturing process.

(Other embodiments)
The embodiment of the present invention is not limited to the contents of the above embodiment, and can be modified as follows, for example. Further, the following modified examples are not applied only to the above embodiment, and different modified examples can be implemented in combination with each other.

With reference to FIG. 5, the structure which provided the heat insulation member 70 as an example of the member is demonstrated.

  The support member 32 is formed with an accommodating portion 32D that accommodates the heat insulating member 70. The housing portion 32D is provided with a heat insulating member 70. As the heat insulating member 70, a member formed of a resin material and having a honeycomb structure is used.

  According to this configuration, heat transfer from the heater 51 to the support member 32 is hindered by the heat insulating member 70, so that heat is radiated from the heater 51 compared to a configuration in which the heater 51 and the support member 32 are in direct contact. The amount of heat transferred to the member 60 increases.

  -As said heat insulation member 70, what was formed from materials other than a resin material can also be used. In addition, as the thermal insulating member 70, a member having a structure different from the honeycomb structure can be used.

  In the above embodiment (FIG. 4), the entire surface of the portion of the heater 51 that faces the support member 32 is in contact with the support member 32, but a gap is formed between the support member 32 and the heater 51. You can also An example of a configuration in which a gap is formed will be described with reference to FIG.

  A plurality of projecting portions 34 projecting toward the heater 51 are formed on the inner side surface 32 </ b> B of the support member 32. The support member 32 supports the heater 51 in a state where the tip end surface of the protruding portion 34 is in contact with the heater 51 and the inner side surface 32B other than the protruding portion 34 is not in contact with the heater 51. For this reason, a gap G is formed between the support member 32 and the heater 51. According to this configuration, since the heat transfer from the heater 51 to the support member 32 is hindered by the gap G, the amount of heat transfer from the heater 51 to the heat radiating member 60 compared to the configuration in which the gap G is not provided. Will increase.

  In the modification of FIG. 6, the protruding portion 34 may be formed as a member different from the support member 32, and the protruding portion 34 may be fixed to the support member 32. According to this configuration, a material different from the support member 32 can be used as the material of the protruding portion 34. For this reason, for example, by using a resin material as the material of the protruding portion 34, the heat insulation effect between the heater 51 and the support member 32 can be further enhanced.

In the modification of FIG. 6, the gap G is formed between the support member 32 and the heater 51 by providing the protruding portion 34 on the support member 32, but the configuration for forming the gap G is as follows. It can also be changed as follows.
(A) A gap G is formed between the support member 32 and the heater 51 by forming a recess in the inner side surface 32B of the support member 32 instead of the protruding portion 34.
(B) Instead of the protruding portion 34, a gap G is formed between the support member 32 and the heater 51 by forming a recess in the surface of the heater 51 that faces the inner side surface 32 </ b> B of the support member 32.

-It is also possible to combine at least two of the configuration of the modification of FIG. 6, the configuration of (A), and the configuration of (B).
In the above embodiment (FIG. 4), the heat application portion 62 is provided with the intermediate portion 62A, the inner portion 62B, and the outer portion 62C, but the outer portion 62C can be omitted. In this case, a configuration in which the outer end face of the intermediate portion 62A is positioned on the virtual plane F2 or a configuration positioned between the virtual plane F2 and the virtual plane F1 can be employed. Even in the configuration in which the outer portion 62C is omitted, the effect (1) of the above embodiment can be obtained.
In the above embodiment (FIG. 1), an example of a configuration in which the kneading ball mechanism of the present invention is applied to the chair-type massage machine 1 having the backrest 11 and the ottoman 12 is shown, but the application of the kneading ball mechanism of the present invention is shown. The subject is not limited to the chair type massage machine 1. For example, applying the kneading ball mechanism of the present invention to a bed-type massage machine that massages while the user is sleeping, or a hand-held massage machine having a kneading ball at the tip of the gripped portion held by the user You can also.
