  However, in general chair type massage machines, armrests are provided on both the left and right sides of the seat part to make the sitting posture easy, and the backrest part can be laid down freely and reclining.

  In such a chair type massage machine, in order to massage both sides of the back, as described above, when protrusions are provided on both sides of the backrest, the positional relationship between the protrusions and the armrests becomes a problem. . In particular, when the backrest is tilted back and forth, the protrusion and the armrest do not interfere greatly, and a part of the body is sandwiched between the upper surface of the armrest and the lower surface of the protrusion. It is necessary to make sure that it does not become important even if it happens.

  As described above, the shape of the protrusion itself and the relationship between the armrest and the armrest are extremely important, and the shape of the armrest and the positional relationship between the protrusion and the armrest must be fully considered. However, Patent Document 1 does not disclose any of these.

  Therefore, in the massage machine that can actually treat both sides (body side) of the back, there are still problems to be solved regarding usability and safety.

  The object of the present invention is to provide a massage machine that can solve the above-mentioned problems.

And offset outward.

In this invention of Claim 5, in the massage machine of any one of Claims 1-4, the whole lower surface of the said body side treatment part was made into circular arc shape, It is characterized by the above-mentioned.

(1) In the present invention of claim 1, comprising a seat portion, a backrest portion attached to the rear portion of the seat portion so as to be raised and lowered, and an armrest portion disposed on the left and right sides of the seat portion, In the massage machine in which the body side treatment part for treating the body side including the user's shoulder is attached to the left and right side parts of the backrest part so that the lower surface of the body side treatment part faces the upper surface of the armrest part , The upper surface of the armrest portion is formed in an arch shape, and at least the latter half portion of the armrest portion is formed in an arc shape substantially the same as the trajectory of the lower end portion of the body side treatment portion accompanying the lying down operation of the backrest portion, and the backrest The distance between the locus of the lower end portion of the body-side treatment portion and the upper surface of the armrest portion accompanying the body lying down movement is set so as to change only within a range corresponding to the thickness of a standard adult hand. Therefore, the user can press and treat the body side firmly from both sides while placing the hand or arm on the armrest, and the user places the hand or arm on the armrest. In some cases, for example, when the backrest portion is raised from a state where the backrest portion is tilted, even if the lower surface of the body-side treatment portion sandwiches a hand or arm between the armrest portion, the risk of injury to the hand can be prevented.

(2) In the present invention according to claim 2, the body-side treatment portion is attached to the backrest portion so that the body-side treatment portion can be flexed in the spreading direction, and the lower end portion of the body-side treatment portion is arranged in the longitudinal direction of the upper surface of the armrest portion. Because it is offset outward with respect to the virtual center line in the direction, for example, when the backrest part is raised from a state where it is tilted, the lower surface of the body treatment part may sandwich the hand or arm between the armrest part, Both sides of the body escape to the outside, and the user can immediately remove their hands and arms.

(3) In this invention of Claim 3 , while attaching the said body side treatment part to the said backrest part so that it can freely bend in the spreading | diffusion direction, the virtual centerline in the front-back longitudinal direction of the lower surface of the said body side treatment part, and the said armrest By making the virtual center line in the longitudinal longitudinal direction of the upper surface of the part intersect in plan view, both the body side back part escapes to the outside, and the user can immediately remove the hand and arm. Further, in this case, the distance between the distal ends of the body side treatment parts is wider than the width of the backrest part. Therefore, even when leaning against the backrest part, the body side treatment parts do not get in the way and the usability is improved.

(4) In this invention of Claim 4 , while attaching the said body side treatment part to the said backrest part so that it can freely bend in the spreading | diffusion direction, the virtual centerline in the front-back longitudinal direction of the lower surface of the said body side treatment part, and the said armrest The virtual center line in the front-rear longitudinal direction of the upper surface of the part intersects in plan view, and the lower end portion of the body-side treatment part is offset outward with respect to the virtual center line in the front-rear longitudinal direction of the upper surface of the armrest part As a result, both body side back parts can easily escape to the outside, and the user can immediately remove their hands and arms. Furthermore, since the distance between the distal ends of the body-side treatment portions is wider than the width of the backrest portion, the body-side treatment portions do not get in the way even when leaning against the backrest portion, and the usability is improved.

(5) In the present invention according to claim 5, when the entire back surface of the body side treatment portion is formed in an arc shape, the locus of the lower end portion of the body side treatment portion and the upper surface of the armrest portion when the backrest portion is caused to fall down The distance between and is almost the same at any position, and there is no risk of strongly pinching the user's hand or arm .

The massage machine according to the present embodiment includes a seat portion, a backrest portion attached to the rear portion of the seat portion so as to be raised and lowered, and armrest portions disposed on the left and right sides of the seat portion. In the massage machine in which the body side treatment part for treating the body side including the user's shoulder is attached to the left right side so that the lower surface of the body side treatment part faces the upper surface of the armrest part, the armrest part The upper surface is formed in an arch shape, and at least the latter half of the armrest is formed in an arc shape substantially the same as the trajectory of the lower end of the body-side treatment part associated with the lowering operation of the backrest, and the lowering of the backrest The distance between the locus of the lower end portion of the body-side treatment portion and the upper surface of the armrest portion that accompanies the movement is set so as to change only within a range corresponding to the thickness of a standard adult hand. Therefore, even if the lower surface of the body-side treatment part sandwiches a hand or arm between the armrest part, it is possible to prevent the possibility of damaging the hand. In addition, it is possible to prevent a possibility that a hand is caught because the interval is too narrow, and that a hand is damaged, and a possibility that a child or the like accidentally pinches a neck or the like because the interval is too wide can be prevented.

Furthermore, the body side treatment part is attached to the backrest part so as to be freely bent in the spreading direction. Then, the side imaginary center line in the longitudinal length direction of the lower surface of the treatment section and the virtual center line in the longitudinal length direction of the upper surface of the armrest portion intersect in a plan view, and the lower end portion of the side treatment portion, the armrest It is offset outward with respect to the virtual center line in the longitudinal direction of the upper surface of the part. That is, the body-side treatment portion is configured to expand forward from the base end portion of the attachment to the backrest portion, and when the body-side treatment portion is disposed on the left and right of the backrest portion, it is substantially C-shaped in plan view. In addition, the lowermost end point of the body-side treatment portion is positioned so as to be shifted outward with respect to the virtual center line in the front-rear longitudinal direction of the upper surface of the armrest portion.

  The backrest is provided with a mechanical massage unit equipped with fir balls as a treatment body so that it can be raised and lowered. On the left and right sides of the massage unit, there is also a treatment body that is an air massager. A back airbag that can be used is provided. Furthermore, although the treatment body provided in the body side treatment part provided in the right and left both sides of the backrest part may be a mechanical type, it is an airbag here.

  With the above-described configuration, the user can perform treatment by pressing the body side firmly from both sides while placing the hand or arm on the armrest, and the user can place the hand or arm on the armrest. When placed, for example, when the backrest part is raised from a tilted state, even if the lower surface of the body side treatment part sandwiches a hand or arm between the armrest part, the body side treatment part is easily bent. And since the lower end of this body side treatment part is offset to the outside with respect to the virtual center line of the armrest part, the body side back part easily escapes to the outside, so the user should immediately remove his hands and arms. Can do.

  Moreover, in the said structure, since the space | interval between the front-end | tips of a body side treatment part is wider than the width | variety of the said backrest part, even when leaning against a backrest part, a body side treatment part does not become obstructive and usability improves.

  Furthermore, it is preferable that the armrest portion and the body-side treatment portion are arranged so that the left and right lateral widths when viewed from the front are within substantially the same region.

  That is, when the user places his / her hand or arm on the armrest, for example, when the user wakes up from a state in which the backrest is tilted, the lower surface of the body-side treatment part is placed between the hand or arm and the armrest. Even if it is sandwiched between the hands and arms, the hands and arms are not strongly pinched by the edge of the lower surface of the body-side treatment section, so there is no risk of damaging the hands and arms, and the hands and arms can be easily detached.

  Moreover, it is good to form the upper surface of the said armrest part with a flexible member.

  For example, if the upper surface of the armrest portion is covered with a cover body containing a cushion material or the like, the appearance will be good. As described above, when the user places his / her hand or arm on the armrest, for example, when the user wakes up from a state in which the backrest is tilted, the lower surface of the body-side treatment unit holds the hand or arm. Even if it is pinched between the armrests, the hands and arms can sink on the upper surface of the armrests and the pinching pressure can be released, so the safety is further improved.

  Moreover, the said body side treatment part can be moved up and down.

  That is, even when the height of the user is greatly different, the optimum body treatment according to the user can be performed.

  Further, when the vertical movement is performed, a manual method may be used, but a configuration in which a separate driving unit is provided and the vertical movement is possible can be employed. In this case, for example, when a predetermined pressing force is detected and controlled so as to automatically move in a direction in which the pressing force is released, in this case as well, when the backrest portion is raised from a tilted state, the body side Even if the lower surface of the treatment part sandwiches the hand or arm between the armrest part, the body side treatment part can move upward to release the clamping pressure.

  Further, for example, it is also possible to automatically move up and down according to the user's body shape by electrical control. For example, using a massage unit that can be moved up and down arranged on the backrest, the body shape of the user is detected prior to the start of use of the massage machine, and the body side treatment unit is automatically moved up and down in conjunction with the body shape detection. It can be considered to control the movement. By the way, the technology that enables the body-side treatment unit to move up and down in this way does not necessarily require other constituent requirements.

  Moreover, the upper surface of the said armrest part and the lower surface of the said body side treatment part can each be formed in arch shape.

  With such a configuration, the armrest portion projecting upward from the seat portion and the body side treatment portion projecting forward from the backrest portion are both in an arch shape, and the appearance is balanced and the appearance is good. Since the attachment base end side of the body-side treatment part can be extended as much as possible downward, the treatment body disposed in the body-side treatment part can be disposed longer in the vertical direction. It is possible to treat as wide a range as possible on the body side.

  Furthermore, when both are arranged so that the upper surface of the armrest portion does not contact the lower surface of the body side treatment portion, the user can easily use the armrest portion even when the backrest portion is raised or tilted. You can enjoy massage with posture.

  As another embodiment, the lower end portion of the body side treatment portion may be only configured to be offset outward with respect to a virtual center line in the longitudinal longitudinal direction of the upper surface of the armrest portion, or the body side The configuration may be such that the virtual center line in the longitudinal direction of the lower surface of the treatment part and the virtual center line in the longitudinal direction of the upper surface of the armrest part intersect in plan view.

  In any case, substantially the same effect as the above-described embodiment can be obtained. That is, when the user places his / her hand or arm on the armrest, for example, when the user wakes up from a state in which the backrest is tilted, the lower surface of the body-side treatment part is placed between the hand or arm and the armrest. Even if it is sandwiched between the two, the body side treatment part is easily bent, so both the body side back parts escape to the outside, and the user can immediately remove the hand and arm. In the case of a configuration in which the virtual center line in the longitudinal longitudinal direction of the lower surface of the body side treatment part and the virtual center line in the longitudinal longitudinal direction of the upper surface of the armrest part intersect in plan view, the width of the backrest part Since the distance between the front ends of the body side treatment part is wide, the body side treatment part does not get in the way even when leaning against the backrest part, and the usability is improved.

  By the way, in each embodiment mentioned above, although it was set as the structure which provided the back airbag on the right-and-left side of the massage unit of the backrest part, this back airbag may be provided in the main part of the backrest part, You may provide in the cover which coat | covers a backrest part.

  In any case, it is desirable that the longitudinal center of the back airbag is positioned below the center of the left and right body treatment units.

  That is, when the airbag for the back is inflated with the airbag of the body-side treatment unit being pressed and held from both sides, the back is pushed slightly upward from below and the massage effect is improved. Is possible. Note that the configuration in which the center in the longitudinal direction of the back airbag is positioned below the center of the left and right body-side treatment portions does not necessarily have to include other components.

  Moreover, the airbag provided in the said body side treatment part can also add not only the function to press a body side from right and left but the function to press a user's body against the backrest part side by the arrangement number and arrangement position. .

  For example, if the first airbag disposed around the central portion of the airbag attachment body of the body-side treatment section and the second airbag disposed on the distal end side of the airbag attachment body, The body can be pressed and held from the left and right with the first airbag, and the body can be pressed against the backrest side with the second airbag. Note that this configuration does not necessarily include other configuration requirements in the present embodiment.

  As shown in FIG. 7, the above-described side wall portions 6 and 6 that can treat the body side are disposed such that the inner side portions thereof are in contact with the left and right end surfaces of the backrest portion 3.

  In order to obtain such a configuration, in the present embodiment, the rising portion 35 is formed at the end portion of the backrest plate 31 that forms the side wall portion 6 side to improve the strength, and the angle plate made of steel is used. It is attached to the left and right vertical frames 30 and 30, and a predetermined distance D is provided between each vertical frame 30 and the rising portion of the backrest plate 31.

  And the said side wall part 6 and the backrest board 31 are connected using the stay 40 formed in the substantially L shape which consists of the body side treatment part attachment part 40a and the backrest part side extension part 40b. That is, the side wall portion 6 is connected to the body-side treatment portion mounting portion 40 a, while the backrest portion side extension portion 40 b is connected and fixed to the back surface of the backrest plate 31. In FIG. 7, reference numeral 41 is a side wall connecting bolt, 42 is a backrest connecting screw, and 14 b is a guide roller for ascending / descending guidance of the massage unit 11, which can roll along the vertical frame 30.

  Thus, since the rising part 35 was formed in the said backrest board 31, intensity | strength improved and the backrest part 3 has sufficient intensity | strength as a whole.

  Further, with the above-described configuration, when the airbag a3 of the side wall portion 6 is inflated and the body side of the user M is pressed, the reaction force received by the side wall portion 6 at that time is the backrest plate via the stay 40. 31. However, since the weight of the user M is applied to the backrest plate 31, the user M will eventually receive the side wall portion even if the backrest plate 31 is made of resin. A particularly large load is not applied to the connecting portion with 6.

  Further, even when a force is applied in the direction in which the side wall portion 6 opens outward as in the case where the side wall portion 6 receives a reaction force, the side wall portion 6 is easily bent in the spreading direction. The stay 40 in the form of a bend can be deflected within the distance D, and the received force can be released. Accordingly, no force is applied to the vertical frames 30 and 30 and there is no possibility that the vertical frames 30 and 30 are deformed. Therefore, the vertical frames 30 and 30 are arranged to be raised and lowered via the rack 13 attached to the vertical frames 30 and 30. It is also possible to prevent the massage unit 11 from moving up and down, or to generate abnormal noise during the lifting and lowering.

  In addition, with the above-described configuration, the backrest plate 31 can be made of resin, and the back cover body 32 can be made of the same resin to reduce the weight of the massage machine A as a whole. Cost reduction can be achieved.

  By the way, the rising portion 35 is formed with a notch portion 35a for allowing the back portion extension portion 40b of the stay 40 to escape. Therefore, the backrest side extended portion 40b can be brought into direct contact with the back surface of the backrest plate 31 through the notch 35a, and the stay 40 can be firmly connected and fixed to the backrest plate 31.

  Further, since the connection structure between the side wall portion 6 and the backrest portion 3 is as described above, the inner side portion of the side wall portion 6 is disposed so as to come into contact with the left and right end surfaces of the backrest portion 3. The entire surface can be effectively used without narrowing the front surface of the unit 3, that is, the back receiving surface of the user M. Therefore, regardless of the physique of the user M, massage on both sides of the body including the shoulder portion can be performed slowly. In particular, since there is an acupuncture point called “shoulder” on the shoulder portion, any user M can effectively massage this acupuncture point.

  Further, as a modified example of the attachment structure of the side wall portion 6 to the backrest portion 3, the side wall portion 6 can be moved up and down as indicated by an arrow F shown in FIG.

  As a structure for enabling the side wall portion 6 to move up and down, although not shown, the stay 40 is provided with a rail or the like on the back surface of the backrest portion 3, and the stay 40 extends to the backrest portion side of the connecting member that slides on the rail. What is necessary is just to connect the part 40b.

  Moreover, as a drive structure for moving up and down, a manual structure may be used, but a drive structure that can automatically move up and down by electrical control can also be used.

  As described above, the massage machine A includes the seat portion 1 provided with the armrest portions 5 on the left and right side portions, and the backrest portion 3 attached to the rear portion of the seat portion 1 so as to be freely laid down, and the backrest portion. 3 is provided with side wall portions 6 that can be freely bent in the spreading direction. In this massage machine A, a feature of this embodiment is the longitudinal direction of the lower surface of the body-side treatment portion 6. And the virtual center line CL2 in the longitudinal longitudinal direction of the upper surface of the armrest portion 5 intersect in plan view, and the lower end portion 6a of the body-side treatment portion 6 is connected to the longitudinal longitudinal direction of the upper surface of the armrest portion 5. This is because the position is offset outward from the virtual center line CL2 in the direction.

  Hereinafter, FIG. 5 which is a front view of the massage machine A in a state where the backrest portion 3 is erected and FIG. 6 which is the same plan view, and further an explanatory view showing the positional relationship between the armrest portion and the side wall portion. The side wall 6 and the armrest 5 will be described in detail with reference to FIGS.

  As shown in FIGS. 5 and 6, the side wall portion 6 is formed so as to expand forward from the attachment base end portion 61 to the backrest portion 3, and the side wall portion 6 is formed on the left and right sides of the backrest portion 3. When it is disposed in the shape, it is substantially C-shaped in a plan view (FIG. 6). Therefore, the virtual center line CL1 in the longitudinal longitudinal direction of the lower surface of the body-side treatment unit 6 and the virtual center line CL2 in the longitudinal longitudinal direction of the upper surface of the armrest 5 intersect each other in plan view.

  With this configuration, the user M can perform treatment by pressing the body side firmly from both sides by the side wall portion 6 while placing the hand or arm on the armrest portion 5. When the arm is placed on the armrest part 5, for example, when the backrest part 3 is raised from a state where the armrest part 3 is tilted, the lower surface of the side wall part 6 pinches the hand or arm between the armrest part 5. However, the side wall portion 6 is easily bent, and the virtual center lines CL1 and CL2 of the side wall portion 6 and the armrest portion 5 intersect each other in a plan view, and the lower end portion 6a of the body side treatment portion 6 is the armrest portion 5. Since the side wall portion 6 is easy to escape outward with respect to the virtual center line CL2 in the front-rear longitudinal direction of the upper surface, the user M instantly holds the hand or arm when the hand or arm is pinched. It can be removed and safety is improved.

  Furthermore, in this case, since the width between the tips of the left and right side wall parts 6 is wider than the lateral width of the backrest part 3, the side wall part 6 becomes an obstacle when the user M leans against the backrest part 3. There is no, and usability improves.

  Aside from usability, the left and right side wall portions 6 and 6 are attached to the backrest portion 3 without being particularly C-shaped in plan view, that is, the upper surface of the armrest portion 5 and the lower surface of the side wall portion 6. Even if the virtual center lines CL2 and CL1 in each longitudinal direction do not necessarily cross each other, the lower end portion 6a of the side wall portion 6 is more than the virtual center line CL2 in the longitudinal longitudinal direction of the upper surface of the armrest portion 5, as shown in FIG. It is also possible to just offset to the outside. That is, the lower end portion 6 a of the side wall portion 6 may be shifted outward from the virtual center line CL <b> 2 of the armrest portion 5. Even with this configuration, the same effects as described above can be obtained. That is, the side wall portion 6 is easy to bend and the center position of the lower end portion 6a is shifted to the outside of the virtual center line CL2 of the armrest portion 5, so that the lower surface of the side wall portion 6 can move the hand or arm to the armrest portion 5. Even if it is pinched, the side wall portion 6 bends outward, and the sandwiched arm can be immediately released.

  Moreover, without offsetting the lower end part 6a of the side wall part 6 outside the virtual center line CL2 in the longitudinal direction of the upper surface of the armrest part 5, the lower surface part of the body side treatment part 6 in the longitudinal direction of the longitudinal direction. The virtual center line CL1 and the virtual center line CL2 in the longitudinal direction of the upper surface of the armrest portion 5 may be configured to intersect each other in plan view.

  That is, if the side wall portion 6 is arranged on the left and right sides of the backrest portion 3 and has a substantially C shape in a plan view, the side wall portion 6 can easily escape to the outside, and when the hand or arm is sandwiched. The user M can immediately remove his / her hands and arms.

  Moreover, in the structure which comprises the characteristics of this invention, as shown in FIG. 11, it is desirable for the upper surface of the armrest part 5 to be a bowl-shaped mountain shape by sectional view. With such a configuration, the side wall 6 escapes to the outside more easily with respect to the sandwiched arm. By the way, this chevron shape is not limited to the one having the apex at the center (on the virtual center line CL2) as shown in FIG. For example, as shown in FIG. 12 and FIG. 13, if the lower end 6 a of the side wall 6 is shifted so as to be located outside the virtual center line CL <b> 2 of the armrest 5, the top of the mountain shape coincides with the center. There is no need. FIG. 12 shows an example in which the top is positioned slightly outside the virtual center line CL2, and FIG. 13 shows an example in which the top is positioned on the outermost side.

  Furthermore, in this embodiment, the upper surface of the said armrest part 5 is formed with the flexible member. That is, the handrail body 50 provided with a cushion material etc. is attached inside. Thus, since the part with which the hand and arm of the user M contact | abut directly is comprised by the flexible handrail body 50, the user M mounts a hand and an arm in the said armrest part 5 (handrail body 50). As described above, for example, when the backrest 3 is raised from a state where the backrest 3 is tilted, even if the lower surface of the side wall 6 sandwiches a hand or arm between the handrail body 50, Further, the arm can sink on the upper surface of the flexible handrail body 50 and the pinching pressure can be released, which makes it safer.

  In the configuration described above, in the present embodiment, as shown in FIG. 4, at least the rear half 50 a of the handrail body 50 provided on both armrests 5, the lower end of the side wall 6 associated with the overturning operation of the backrest 3. It is formed in an arc shape substantially the same as the locus of the part 6a, and the handrail body 50 and the side wall part 6 are configured not to contact each other.

  That is, the handrail body 50 is formed in a curved arch shape, and the lower end portion 6a of the side wall portion 6 is also curved so that the rear half portion 50a of the handrail body 50 and the lower end portion 6a of the side wall portion 6 are closest. Even so, there is no interference.

  Therefore, the handrail body 50 and the side wall portion 6 do not interfere with each other when the backrest portion 3 is erected or tilted, and the rear half portion 50a of the handrail body 50 has a curved shape and is gently rearward. Since the user M can use the armrest part 5 without difficulty even when the backrest part 3 is tilted, the user M can perform a massage while always maintaining an easy posture. That is, even when the user M is sitting or sleeping, the user can massage the arm resting on the armrest part 5 or placing the hand on the handrail part 50.

  More specifically, a distance d that does not exceed a predetermined range is maintained between the locus L of the lower end portion 6a of the side wall portion 6 and the handrail body 50 that accompanies the lying down operation of the backrest portion 3. It is possible to do so so that they never come into contact.

  In addition to not contacting, the closest approach is when the backrest 3 is erected, but the distance d1 = 18 mm when the backrest 3 is approached, while the maximum spread when the backrest 3 is tilted d2 = 30 mm. Here, the range of 18 to 30 mm as the distance corresponds to the thickness of a standard adult hand, and when the backrest portion 3 is reclined, the handrail body 50 and the lower end portion 6a of the side wall portion 6 are used. The distance d is shifted only within a range corresponding to the thickness of the hand.

  Therefore, the distance d is too narrow to prevent a hand from getting hurt, and the distance d is too wide to prevent a child from accidentally pinching the neck or the like. Yes.

  Moreover, it can also be set as the shape shown in FIG.14 and FIG.15 as a modification of the said side wall part 6. FIG.

  In the configuration shown in FIG. 14, the external shape of the side wall portion 6 is also an arch shape. That is, the upper surface (handrail portion 50) of the armrest portion 5 and the lower surface of the side wall portion 6 are each formed in an arch shape. With such a configuration, the external appearance of the massage machine A is balanced and the appearance is good, and the attachment base end side of the side wall portion 6 can be extended as much downward as possible. Therefore, the body side treatment portion mounting portion 40a of the stay 40 for attaching the side wall portion 6 to the backrest portion 3 can be formed vertically long, and the side wall portion 6 can be firmly attached to the stay 40. In addition, since the airbag a3 can be disposed long in the side wall portion 6 in the vertical direction, it is possible to treat the body side as widely as possible.

  In addition, what is shown in FIG. 15 is one in which the entire lower surface of the side wall portion 6 is formed in a concave shape along a handrail body 50 having an upwardly convex arch shape. In such a configuration, if the distance d is set to an appropriate value, the distance d becomes substantially the same at any position when the backrest portion 3 is inclined, and the user M's hand or arm is strongly pinched. There is no fear.

  By the way, in the present embodiment, as shown in FIG. 5, the side wall portion 6 and the handrail so that the lateral width of the bottom surface portion of the side wall portion 6 and the lateral width of the handrail body 50 fall within substantially the same region E. The body 50 is disposed facing the body 50.

  This is to prevent the distance d (d1, d2) between the handrail body 50 and the lower end portion 6a of the side wall portion 6 from becoming narrower than the standard hand thickness as described above. No, since it is a standard hand thickness, some users M may be subjected to a certain pinching pressure. At that time, for example, when one of the bottom surface portion of the side wall portion 6 and the handrail body 50 protrudes outside the region E, the pressure is received by the bottom surface portion of the side wall portion 6 and the edge of the handrail body 50, There is a possibility that a force in the shearing direction may be exerted on the pinched hand, which may cause extremely unpleasant pain, but if it is configured to fit within the same region E as described above, the user M The hand is only sandwiched between the bottom surface of the side wall portion 6 and the surface of the handrail body 50, and only needs to receive a pressing force between the surfaces (in some cases, it receives massage by pressing force). .

  In addition, as described above, in this embodiment, the virtual center line CL2 in the longitudinal direction of the upper surface of the armrest portion 5 and the virtual center line CL1 in the longitudinal direction of the lower surface of the side wall portion 6 intersect with each other in plan view. Since the virtual center lines CL2 and CL1 are offset and shifted in the left-right direction so that the hands and arms can be immediately released, a multi-layered and safe structure can be achieved.

  Further, as described in the modification of the mounting structure of the side wall portion 6 to the backrest portion 3, the side wall portion 6 can be configured to be electrically movable up and down. In this case, a predetermined pressing force is detected. It is also possible to electrically control the side wall portion 6 to move in a direction (usually upward) in which the pressing force automatically decreases. If such control is performed, safety is further improved.

  As described above, in the massage machine A according to the present embodiment, the user M can perform a massage with a relaxed and comfortable posture even when the user M is sitting or sleeping. Moreover, it has an excellent configuration in terms of safety, and can significantly increase the value as a chair type massage machine.

  FIG. 16 shows a remote controller R attached to the massage machine A according to this embodiment. A massage execution command is given to the control unit G from the remote controller R having a massage type and strength selection function.

  The remote control R has a display screen K made up of a liquid crystal display device on the upper side, and an operation unit S made up of a plurality of buttons on the lower side. In addition, a part of the operation unit S is openable and closable, and an automatic course that combines mechanical massage and air massage can be selected for the lid R1. In the opened main body R2 shown in FIG. 17, mechanical massage and air massage can be individually selected by manual operation. In addition to such a massage operation, reclining of the backrest 3 and raising / lowering of the leg rest 4 can be performed.

  Here, various operation buttons provided on the remote controller R will be briefly described. In FIG. 16, S3 is a start / storage button, which is used when starting massage or storing the balls 7, 7 even after the massage is finished. S4 is a stop button, which can stop the massage halfway. S5 is an up / down button, which can move the kneading balls 7, 7 up and down. S6 is an automatic course button group, which can be selected from a course of neck / shoulder, whole body, and waist. S7 is a strength button, and the massage strength in the automatic course can be set in five stages. S8 is an abbreviated button, and a shortened automatic course can be selected.

  S9 to S13 are operation buttons for air massage, and S9 is a shoulder button, which turns on / off the supply of air to the airbag a3 provided on the side wall 6 in the automatic course. The air pressure can be selected from five levels. S10 is a foot stretch button which can be turned on / off during the automatic course. S11 is a pulse button which can be turned on / off during an automatic course. S12 is a leg air button, which can switch between leg, leg simultaneous, and leg cut. S13 is an air strength button, which can switch the strength of the air pressure during the automatic course in five stages. S14 is a vibrator button for turning on / off the vibrator massage. S15 is a heater button for turning on / off a heater (not shown) provided in the seat portion 1 and the backrest portion 3. S16 is an ottoman button that raises / lowers the leg rest 4. Note that air supply is stopped during button operation. S17 is a reclining button, and the angle of the backrest 3 can be changed. Air supply is stopped during button operation.

  In addition, operation buttons capable of operating individual functions are arranged on the main body R2 shown in FIG. S20 is a function selection button, and a function can be selected from 10 types of massages. S21 is a stretch button, which can select a combined operation in which a stretching operation is added to the stroke. S22 is a 3D button, and it is possible to select a combined operation in which a 3D operation is also added. Here, the 3D operation is a massage function in which the back and forth movement operation of the fir balls 7 and 7 is added to the massage of “Rise Up”, “Rice Down”, “Tataki”, and “Sazanami”. S23 is a whole / partial button, which can set a massage range while moving the massage unit 11 up and down. S24 is a speed adjustment button, S25 is a width adjustment button, and S26 is a strength adjustment button, which can adjust the strength of the massage in seven stages.

  S27 is a shoulder button, which supplies and stops air to the airbag a3 on the side wall 6. With this shoulder button S27, effective air massage can be performed on the shoulder and the body, including the acupuncture points. The treatment on the body side including the shoulder by the operation of the shoulder button S27 will be described in detail later.

  Moreover, S28 is a site | part button and can select the location which performs air massage. S29 is a foot stretch button, which turns foot stretch on and off. S30 is a pulse button that turns on / off the air pulse. S31 is a leg simultaneous button, and when the button is operated while air massage is being performed at other locations, the leg can be simultaneously air massaged. S32 is an air strength button, which can switch the air pressure in five stages.

  When a command for performing a predetermined massage or massage course is given by operating the remote controller R, the control unit G controls the massage unit 11 and the airbags a1 to a8 based on the given command.

  Here, control when the shoulder button S27 is operated will be described.

  In the present embodiment, when the shoulder button S27 is operated, the air pump 25 is driven to supply air to the body side airbag a3 at a predetermined pressure, as shown in FIG. Air bag a1 is supplied with a predetermined pressure. Then, as shown in FIG. 25, the shoulder air strength setting screen is first displayed on the display screen K of the remote controller R.

  The pressing force applied to the body by the body side airbag a3 disposed on the side wall 6 varies as the massage force received by the user M depending on the body shape of the user M even if the air pressure is the same. This is because it is necessary to first set a reference strength corresponding to M. That is, unlike the case where the treatment portion is a surface and the surface is pressed, when a treatment body having a width is pinched from both sides, the massage force, that is, the pinching pressure varies depending on the size of the width. As described above, with respect to the strength depending on the body shape, it is necessary to set a reference strength corresponding to the body shape in advance.

  In the present embodiment, the strength that can be set is set to five levels, and the initial setting is an intermediate strength 3 as shown in the figure.

  The user M presses the shoulder button S27 while feeling the pressing force with the initially set strength 3, and sets a reference strength according to his / her preference while feeling the change in strength with the body. Here, each time the shoulder button S27 is pressed once from the initial setting state, the strength increases by one step. In the illustrated screen, the left end is the strongest 5 and the right end is the weakest 1. The strength is displayed in blocks. Then, after the strongest position at the left end, a “cut” state is set. However, if the reference strength is set for the first time when the massage machine A is activated for the first time, the shoulder button S27 is operated and the initial strength 3 is displayed again. When the shoulder button S27 is pressed, the strength becomes “cut” instead of the strength 4, and the strength is gradually increased from 1 to 5 from the third push button operation. This is because, in the case of the initial setting, the level difference in one step of the intensity is often unknown, so that after the initial setting value, it can be experienced step by step from the weakest.

  As described above, the strength control of the predetermined treatment body (in this case, the body side airbag a3) whose massage force depends on the body shape is controlled by other treatment bodies (in this case, for example, the back airbag a1 and the waist airbag a2). In addition to being controlled independently, the standard strength of the prescribed treatment body can be set independently, so that the user M of any body shape can be treated with the strength setting that suits him / her It can be performed.

  In addition, as the treatment body which generates the clamping pressure, the body side airbags a3 and a3, the leg upper airbags a7 and a7, the leg lower airbags a8 and a8, and the like from the left and right or front and rear. Not only those that can be clamped but also one side of the body side is clamped in an oblique direction like the one side body side airbag a3 and back airbag a1 as in this embodiment. Including cases.

  As described above, the massage machine A according to the present embodiment can select and massage the automatic course from the remote controller R, and does not suit his / her preference during the course of the automatic course. You can skip this if you are in massage mode, or you can repeat it if you are in your favorite massage mode.

  For this purpose, as shown in FIG. 16, the remote controller R is provided with a repeat button S1 serving as a repeat switch and a skip button S2 serving as a skip switch. Moreover, these buttons S1 and S2 are arranged on the left and right sides at a predetermined interval at a substantially central position of the operation unit S. Therefore, it is easy to selectively operate the buttons, and it is easy to skip unnecessary massage modes, or to repeat this if it is a favorite massage mode, whenever you think of it. Can be done.

  As described above, the massage machine A according to the present embodiment is provided for the expansion and contraction of the airbags a1 to a8 and the operation of the kneading balls 7, 7 provided in the massage unit 11, and the kneading balls 7, 7. Depending on the operation of the vibrator, multiple types of massage can be performed by air massage, shiatsu, fir tree, tapping, and vibration, and the massage unit 11 can be moved up and down at an appropriate speed, or moved back and forth to adjust the strength of the massage. Various massage modes can be created by changing them.

  Then, a short program for executing each of these massage modes is created, and a plurality of types of automatic courses are set by a massage program in which such short programs are appropriately combined, and this massage program is stored in the memory unit of the control unit G. Prestored in G1. Each automatic course is programmed to finish in 15 minutes at the longest.

  Then, the user M appropriately selects from among the plurality of automatic courses according to his / her preference, and the user M repeats the remote control R provided while the selected automatic course is being executed in accordance with the massage program. By operating the button S1 or the skip button S2, each massage mode is appropriately skipped to shift to the next massage mode, or if it is a favorite massage mode, this is repeatedly executed for a certain time (for example, for 60 seconds). It can be done.

  Therefore, the user M does not have to unnecessarily perform a massage that does not suit his / her preference, and can be treated in a longer time than a preset time if it is a massage that suits his / her preference, which is more comfortable. It becomes possible to receive a massage.

  In addition, as described above, the short program includes, for example, the inflating / shrinking operation of the airbags a1 to a8, the operation type, operation speed, operation time, vertical and front / rear positions of the kneading balls 7, 7, etc. This short program is assembled into one massage program.

  For example, a short program for the fir mode that performs fir massage with a predetermined strength from the waist to the shoulder, a short program for the fist mode that performs a tapping massage with a predetermined strength from the shoulder to the back, or only the waist An automatic course is configured by combining a number of different short programs, such as a short program for acupressure mode that performs acupressure massage of a predetermined strength.

  Therefore, the skip and repeat of the massage mode in the present embodiment can be easily realized by skipping or repeating the short program.

  Further, some massage modes are accompanied by rolling, such as “rolling tapping” in which the kneading balls 7 and 7 are swung up and down while being in contact with the back of the user M.

  In this case, in the present embodiment, when the skip operation is performed, the massage operation by the tapping is not performed, and the massage unit 11 is in the “weak” position, the “sanding mode” position, or the kneading balls 7, 7 moves backward to a position where it does not touch the back to prepare for the next massage.

  Since the massage unit 11 is originally rolling up and down, the movement to the treatment site designated in the next massage mode is performed smoothly, and the pressing force to the user by the kneading balls 7 and 7 is weak. Therefore, the user M can enjoy the next massage mode without strongly experiencing at least the massage of “tapping rolling”. In particular, when rolling with the kneading balls 7, 7 in contact with at least the back, the user M knows the position of the kneading balls 7, 7 even during skipping, so there is a sense of security and the next massage without any sense of incongruity Can receive.

  In addition, as control of the massage unit 11 during skipping, not only the above-described form but also the position of the massage unit 11 when the kneading balls 7 and 7 are retracted and the contact with the back is weakened, the kneading balls 7 , 7 may continue to move up to that point. In this case, it is desirable to increase the moving speed. The skip button S2 of the remote controller R can be configured not to accept a button operation from the user M if the skip operation is currently being performed.

  In order to realize the skip operation and the repeat operation in the massage mode with such rolling, in the present embodiment, specifically, control as described below is performed.

  That is, in the case of the skip operation, as shown in FIG. 18 (a), for example, a short program (B) for 30 seconds of massage massage at the neck position → rolling for 30 seconds from the neck to the vicinity of the scapula Short program (C) → There is a short program (D) for 30 seconds of rolling up from the vicinity of the scapula to the neck position, and an automatic course massage program with the following part, among which the short program for rolling (C) When the skip button S2 is operated after about 5 seconds from the start of execution (indicated by the arrow g), the fir balls 7, 7 (massage unit 11) skip as shown by the broken line in FIG. Move to the vicinity of the scapula at a relatively higher speed than the speed set in the short program (C) To. Here, the speed is set so that the movement is completed in about 5 seconds. At this time, the strength of the massage unit 11 is the “weak” position, or the “rubbing mode” position where the kneading balls 7 and 7 touch the back lightly, or the kneading balls 7 and 7 touch the back. The user M is retracted to a position where there is no such a feeling that the user M is being massaged, and only the rolling operation is performed. As shown in the figure, this operation is as if a temporary temporary short program (C ') for skipping is automatically generated and inserted, so that the massage program proceeds smoothly.

  In this way, when rolling tapping from the neck to the vicinity of the scapula is not desired, the user M may operate the skip button S2 of the remote control R at any time. While retreating to such an extent that the operation is not conscious, it quickly moves to the treatment position set in the next short program, and massage is started in the next massage mode. That is, massage is started in accordance with a short program of rolling up (D) from the vicinity of the scapula to the neck.

  Also, if you do not like this rolling up (D), you can skip at any time as described above.

  Further, the fact that the skip has been made can be displayed on the display screen K of the remote controller R.

  That is, as shown in FIG. 19, on this display screen K, during the automatic course execution, the type of massage mode being performed and the treatment position are displayed visually and in an easy-to-understand manner using characters or designs. . That is, on the display screen K, the course display (for example, “whole body”, “shoulder”, “waist”, “leg”, etc.), the currently performed massage mode, the remaining massage time of the automatic course currently being executed, The massage mode to be performed next to the currently performed massage mode, massage strength, items related to air massage and vibrator massage, etc. are displayed in text, and the operation state of the airbags a1 to a8 and the massage unit 11 are described by following the human body. The current position can be displayed as an image. In particular, since the massage mode to be performed next can be visually recognized, it is easy to determine whether or not to skip the currently performed massage mode when the next massage mode is the preference of the user M. The display screen K may be provided not only on the remote controller R but also a large display screen. Further, the display screen K does not necessarily need to be configured by a liquid crystal display device.

  As described above, during the execution of the predetermined automatic course, the “rolling tapping” massage mode is executed, and the user M skips this “rolling tapping” so that the skip button S2 of the remote control R can be skipped. Is operated from the steady display screen showing the massage mode of “rolling tapping” shown in FIG. 19A, the position where “rolling tapping” was displayed on the steady display screen as shown in FIG. 19B. “Skip” is displayed on the screen. During this time, the massage unit 11 prepares for the next short program (here, “rolling up”). By the way, in the present embodiment, as the massage strength displayed on the display screen K during skipping, the strength of “rolling hit” (here “3”) currently being skipped is displayed as it is. The contents of the skipped massage mode can be grasped to some extent. For example, the actual position in the front-rear direction of the skipped balls 7 and 7 is converted into "massage strength" and displayed numerically. You can also. In this case, there is an advantage that it is possible to visually confirm how much the kneading balls 7 and 7 are retracted or not.

  On the other hand, when the repeat button S1 is operated, the currently executed massage mode is repeated for a certain time. In this embodiment, the repetition time is set to 60 seconds.

  For example, when a predetermined automatic course is executed, as shown in FIG. 20A, a massage mode of “shoulder pressure on the shoulder 15 seconds” is executed, and the user M applies this “shoulder pressure on the shoulder”. Likely, when the repeat button S1 of the remote controller R is operated, the control unit G controls to perform “shoulder pressure on the shoulder” again for 60 seconds from the operation timing (FIG. 20B). That is, the user M can receive a massage by “shoulder shiatsu” for 70 seconds. Then, when the repeat button S1 is operated again after 40 seconds from the previous repeat operation, that is, 50 seconds after the first massage of “shoulder shiatsu” is started, the “shoulder shiatsu” of 60 seconds from that point of time is operated. It starts (FIG. 20 (c)). That is, the user M can enjoy a massage by “shoulder pressure on the shoulder” for 110 seconds. It is not always necessary to execute “shoulder pressure on the shoulder” for 110 seconds, and the skip operation by the skip button S2 described above can be performed at any time to shift to the next massage mode.

  By the way, when it is desired to repeat this “shoulder pressure on the shoulder”, the user M may operate the repeat button 52 again while executing this “shoulder pressure on the shoulder”. From that point on, “tapping” for 60 seconds is executed again, so that the user M can enjoy his / her favorite massage mode until the end.

  Note that the repeat operation substantially extends the execution time of a predetermined massage mode in one automatic course, but the 15-minute massage time set for the entire automatic course does not change. In this case, for example, the short program set at or near the end in the program of the automatic course is omitted.

  Further, the repeat function is effective even when this repeat operation is performed during the aforementioned massage with rolling, and in this case, the repeat function is repeated for at least 60 seconds. If the position of the massage unit 11 after 60 seconds is different from the position specified in the next short program, the massage with the rolling during the repeat is continued and moved to the predetermined position while rolling. I am doing so. That is, in the repeat operation, the short program for executing the massage is not stopped halfway. That is, it is determined that the user M likes the current massage as much as a repeat operation is required, so there is no problem even if the massage time is slightly shifted in the extension direction.

  In order to realize the repeat operation of the massage mode with such rolling, in the present embodiment, specifically, the following control is performed.

  As shown in FIG. 21 (a), for example, a short program (B) for performing a 30-second napping massage at the neck position → a short program (C) for performing a 30-second rolling napping from the neck to the vicinity of the scapula → scapula There is a short program (D) that runs rolling up from the vicinity to the neck position for 30 seconds and an automatic course massage program that has the following part, and the short program (C) for rolling is started within 25 seconds. When the repeat button S1 is operated after a short time (indicated by an arrow h), as shown in FIG. 21 (b), after the remaining 5 seconds of the short program, the fir balls 7, 7 (massage unit 11) are broken lines. As shown in the above, the speed is relatively higher than the speed set in the short program (C) for rolling. Moves to the initial position of the program (neck position) (so that complete move here in about 5 seconds), to perform rolling bashing up scapula near again.

  Then, even if 30 seconds, which is the execution time of this short program, has passed, it is within 60 seconds, so the short program (C) for rolling and rolling is repeated again, and the rice balls 7, 7 (massage unit 11) Moves to the neck position again and repeats massage by rolling. In the second repetition (repeat), 60 seconds elapse in the middle of rolling, but as shown in the figure, the short program set to 30 seconds is executed to the end. Therefore, in this case, when the repeat button S1 is operated, the rolling short program (C) is substantially extended for 75 seconds.

  Even at this time, when the short program is repeated and the massage unit 11 returns from the vicinity of the scapula to the neck position, the strength as the massage unit 11 is the “weak” position, or the fir balls 7, 7 are on the back. It is made to retreat to the position of the “surging mode” where it touches lightly, or to the position where the kneading balls 7 and 7 do not touch the back.

  As described above, when the user M likes the rolling strike from the neck to the vicinity of the scapula, the user M may operate the repeat button S1 of the remote controller R at any time, and until at least 60 seconds from the operation point to the vicinity of the scapula. The rolling tapping is repeated.

  Further, the fact that such a repeat has been made is also displayed on the display screen K of the remote controller R.

  That is, as shown in FIG. 22, the massage mode of “rolling tapping” is performed, and when the user M operates the repeat button S1 of the remote controller R in order to repeat this “rolling tapping”, FIG. ) From the steady display screen showing the massage mode of “rolling tap” as shown in FIG. 22 (b), “in repeat” is displayed at the position where “rolling tap” was displayed on the steady display screen. The “rolling strike” is extended for at least 60 seconds from the time of this operation.

  In addition, in the repeat of the massage accompanied by rolling, as described above, not only the massage is terminated and then repeated again after the repeat, but, for example, when the repeat button S1 is operated, 7 may be immediately returned to the initial rolling position, and the reciprocating operation from the initial position to the end position may be repeated a predetermined number of times.

  As described above, in the massage machine A according to the present embodiment, a predetermined massage mode can be skipped or repeated during the automatic course, and the physical condition and mood of the user M that day. Although the massage according to this can be performed, it is also possible to reflect the result of skipping or repeating in the massage program of the automatic course. That is, when the same automatic course is performed next time, the short program that executes the previously skipped massage mode is deleted from the massage program, and the short program is updated so that the previously repeated massage mode is repeatedly executed for a predetermined time. You may make it do.

  Alternatively, a preset automatic course may be stored as it is, and the contents skipped or repeated as described above may be registered in the control unit G as a new automatic course.

  In addition, this massage machine A has a shoulder position adjustment function that allows the user M to adjust his / her shoulder position so that the optimum massage can be executed when the user M selects the automatic course described above. I have.

  Conventionally, there are massage machines equipped with a shoulder position adjustment function, but these are performed while performing a “fir” massage that moves the fir balls 7, 7 in a circular motion. In the massage machine A according to the form, the shoulder position can be adjusted while performing acupressure massage.

  In the present embodiment, the user M first moves the massage unit 11 to an appropriate position near the shoulder, and operates the shoulder position adjustment up / down button S5 provided on the remote controller R. The massage unit 11 is driven by this operation, and as shown in FIG. 3, the kneading balls 7 and 7 themselves do not perform an arcuate operation, and move up and down according to the operation while performing a “acupressure” massage only for a straight movement To do.

  In order to adjust the shoulder position as described above, in the present embodiment, the control unit G has a function of detecting the vertical position coordinates of the kneading balls 7 and 7 during the massage and storing the detected data. Yes.

  That is, when the user M operates the up / down button S5 of the remote controller R so as to move the massage unit 11 to a predetermined position, the lifting / lowering motor m1 provided in the lifting / lowering driving mechanism 12 provided in the massage unit 11 is driven to massage. The unit 11 is moved. When the user M operates the upper / lower button S5 for adjusting the shoulder position, the elevating motor m1 is driven to move the massage unit 11 up and down (arrow f1) within a predetermined range, and the advancing / retreating motor m2 is driven. The acupuncture balls 7, 7 are moved back and forth (arrow f2) to perform acupressure massage (see FIG. 3).

  At this time, from the feeling when the kneading balls 7 and 7 hit the back, the user M stops driving the massage unit 11 with the remote control R when the kneading balls 7 and 7 come to the shoulder position that seems to be optimal for him. To do.

  The coordinate-converted data at the time of the stop is stored in the RAM of the memory unit G1, and the massage machine A uses this position as a reference for the optimum shoulder position of the user M. Based on this reference position, Each massage mode is performed.

  Moreover, the body shape detection function which detects the body shape of the user M can be provided to this massage machine.

  For example, a load current detecting means for detecting a load current during massage is provided as a body shape detecting means. The lift motor m1 is driven so that the massage unit 11 is first placed at the waist position of the user M. While lowering to a certain lowermost position, driving the advancing / retracting motor m2 causes the balls 7 and 7 to retreat to the rearmost position. Then, even if the forward / backward motor m2 is driven at that position, the balls 7 and 7 are protruded toward the back of the user M, and the load current of the forward / backward motor m2 increases when hitting the back. Detected by the load current detecting means and stored in the RAM. Specifically, the detection output of the rotary encoder E provided in the massage unit 11 as advance / retreat drive amount detection means is converted into coordinates via the control unit G and stored in the RAM as the waist position.

  Thereafter, even if the advance / retreat motor m2 is further driven, the balls 7 and 7 are moved rearward to the rearmost position, and the elevating motor m1 is also driven, which is also provided in the massage unit 11. The massage unit 11 is raised by a predetermined distance based on the detection of the rotary encoder E, and the balls 7 and 7 are moved forward even if the advance / retreat motor m2 is driven at that position as described above. By repeating such an operation up to the shoulder position of the user M, the body shape of the user M such as the height and width of the shoulder of the user M and the shape of the back can be detected.

  In the case of having such a body shape detection function, when performing the shoulder position adjustment described above, the kneading balls 7, 7 can be automatically set to the optimum position from the body shape detection result. Even if the kneading balls 7 and 7 are moved up and down, the contact force of the kneading balls 7 and 7 to the user M is not too strong, and the shoulder position can be adjusted comfortably.

  Further, as described above, since the optimum shoulder position is determined while performing acupressure massage, it can be regarded as the optimum shoulder position for the user M when performing acupressure massage. As described above, even when the kneading balls 7 and 7 are rotationally driven even when the lifting and lowering of the massage unit 11 is stopped, the optimum shoulder position may be different even for the same user M.

  Therefore, a correction value can be determined in advance for each of various massage modes so that the optimum shoulder position can be corrected each time the user M selects the massage mode. That is, the vertical position coordinate data of the kneading balls 7 and 7 stored when the user M adjusts the shoulder position is automatically corrected by a predetermined value according to the selected massage mode.

  With the massage machine A having such a correction function, a comfortable massage for the user M is always possible regardless of the massage mode selected by the user M.

  In addition, when the body shape detecting means described above is provided, the side wall portion 6 is automatically moved to the optimum position for the user M in conjunction with the body shape detection in combination with the control that enables the side wall portion 6 to be moved vertically. Can be controlled to move up and down automatically. Thus, if the body shape is detected prior to starting the massage, and the side wall portion 6 is automatically moved up and down to the optimum position based on the result, any height and body shape can be obtained. By simply sitting on the seat 1 and leaning on the backrest 3, effective body-side treatment can be performed, including acupuncture points called “shoulders”.
