When describing the chair-type massage machine 1, as shown in FIG. direction. Further, the chair-type massage machine 1 will be described with the directions shown in FIGS. These directions correspond to the up-down direction, left-right direction, and front-rear direction viewed from the user seated on the chair-type massage machine 1 .

As shown in FIG. 1 and the like, the seat portion 2 is configured by a seat portion frame 4 which is a frame structure in which square bar-shaped frame members are combined in a tower shape. A cushion (not shown) or the like can be placed on the upper side of the seat frame 4 to allow the user to sit. Specifically, the seat frame 4 is composed of two sets of frames, an outer frame 10 arranged outside in the left-right direction (width direction) and an inner frame 11 arranged inside the outer frame 10 in the left-right direction. It is composed by combining structures.

The outer frame 10 is formed in a frame shape by combining the long frame members (rod-shaped frames) described above. A cover 12 of the chair-type massage machine 1 is attached to the outer side (outer side in the width direction) of the outer frame 10, and a mechanical part (movable part) provided inside the outer frame 10 allows the hands and feet of the user to move. It is possible to prevent it from entering. In addition, on the lower side of the outer frame 10 (base end side of the frame body), leg portions 13 (grounding portions) are formed of rubber or the like to prevent the frame member from directly contacting the floor surface at the front, rear, left, and right corners. is provided, and the outer frame 10 can be installed on the floor in an upright state via the leg portions 13 . Inner frames 11 are arranged on the inner sides of the outer frames 10 in the width direction, in other words, on the inner sides of the left and right outer frames 10 .

The inner frame 11 is formed of a frame-shaped frame structure that is rectangular in plan view, and is supported by the upper portion of the outer frame 10 so that the inner frame 11 can be lifted upward from the floor surface with which the outer frame 10 is in contact (grounded). It can be supported in a floating state (suspended state). Inside the inner frame 11, seat guide rails 7 for moving the seat massaging mechanism 6 in the front-rear direction are arranged on the left side and the right side of the inner frame 11, respectively. The seat massaging mechanism 6 can be guided in the longitudinal direction.

As shown in FIGS. 2 and 3 , the seat massaging mechanism 6 is a member capable of massaging the treatment area (the treatment area from the buttocks to the thighs) of the user seated on the seat 2 . The seat massaging mechanism 6 is mounted on a base body 14, and the base body 14 is movably mounted on the seat guide rails 7, so that the seat massaging mechanism 6 moves in the front-rear direction. It is possible.

The seat massaging mechanism 6 also includes a seat massaging body 15 that performs massaging operations such as kneading, tapping, and gripping the user's treatment area. Specifically, the seat massaging body 15 of the seat massaging mechanism 6 of the first embodiment includes a lower kneading massage member 16 that kneads and massages the treatment area from the buttocks to the thighs from below, and a lower kneading massage member 16. A lateral kneading massaging member 17 that performs pressure massage with the treatment portion sandwiched therebetween is composed of two types. These lower kneading massaging member 16 and lateral kneading massaging member 17 can be simultaneously driven by one seat kneading drive unit 18 (driving motor) provided in the seat massaging mechanism 6 described above.

Specifically, the seat massaging mechanism 6 includes a seat massaging driving unit 18 (driving motor) that generates a rotational driving force, and a rotating shaft that is driven to rotate by the rotational driving force generated by the seat massaging driving unit 18. 19 and . In the chair-type massage machine 1 of the present embodiment, the seat kneading drive unit 18 is arranged substantially in the center of the base body 14 (seat massaging mechanism 6) in the left-right direction. The resulting rotational driving force is transmitted to a gear wheel 21 provided on the halfway side of the rotation shaft 19 in the left-right direction via a speed reduction mechanism 20 using a worm gear. In addition, lower kneading massage members 16 are provided on both left and right sides of the gear wheel 21, respectively, and lateral kneading massage members 17 are provided further outside the lower kneading massage members 16 in the width direction. The member 16 and the lateral kneading massaging member 17 are configured to operate using a rotational driving force generated by one seat kneading drive unit 18 .

The lower kneading massaging members 16 are arranged on the right side and the left side of the seat massaging mechanism 6, respectively, and are provided as a left and right pair. Each lower kneading massaging member 16 can swing back and forth in the horizontal direction by converting the rotary motion of the rotating shaft 19 using a cam.
Specifically, the lower kneading massaging member 16 includes a lower kneading inclined boss member 22 that rotates together with the rotating shaft 19, and a proximal end that is rotatably fitted to the outer peripheral side of the lower kneading inclined boss member 22. a lower kneading massage arm 23, a lower kneading regulating portion 24 that restricts the lower kneading massage arm 23 from rotating integrally with the lower kneading inclined boss member 22, and directions away from the rotating shaft 19 (front upper side and rear upper side). and a lower kneading treatment element 25 provided on the distal end side of the lower kneading massage arm 23 projecting outward.

The lower kneading inclined boss member 22 is a substantially cylindrical member that is coaxial with the rotating shaft 19, and has a lower kneading inclined cam surface that revolves around the axis inclined with respect to the axis of the rotating shaft 19 on the outer peripheral surface. have. The base end side of the lower kneading massage arm 23 is slidably fitted on the inclined lower kneading cam surface.
The lower kneading massage arm 23 has an annular hole on the base end side that is rotatably fitted into the lower kneading inclined cam surface, and protrudes radially outward (in the direction away from the rotating shaft 19) from the base end side. A lower kneading treatment element 25 is provided on the distal end side to perform treatment by contacting the treatment area.

In the case of the chair-type massage machine 1 of the present embodiment, the lower kneading massage arm 23 has a structure in which the lower kneading massage arm 23 protrudes from the rotating shaft 19 toward the front side and the rear side of the rotating shaft 19 in a bifurcated shape. , has a lower massaging treatment element 25 at its tip. In other words, the lower kneading massage arms 23 of the present embodiment protrude slightly upward, and all of them extend in a crawling manner along the horizontal direction. Therefore, consideration is given so that it is not necessary to secure a large space in the vertical direction.

Further, of the lower kneading massage arms 23 branched in a bifurcated shape, the front arm member 23F extending forward and the rear arm member 23R extending rearward have substantially the same height at the tip. The lower massaging treatment element 25 on the front side and the lower massaging treatment element 25 on the rear side, which are attached to the respective tips, have substantially the same height.
On the other hand, on the base end side of the lower kneading massage arm 23 described above, a lower kneading restricting member 26 is provided to restrict the lower kneading massage arm 23 from rotating together with the lower kneading inclined boss member 22 . The lower kneading regulation members 26 of the present embodiment are projections (lower kneading regulation projections) that protrude from the base ends of the lower kneading massage arms 23 toward the front and rear sides. The base body 14 located on the side is provided with a lower kneading regulation plate 27 that contacts with the lower kneading regulation member 26 to regulate the rotation of the lower kneading massage arm 23 . That is, by providing the lower kneading regulating portion 24 that brings the lower kneading regulation member 26 of the lower kneading massage arm 23 into contact with the lower kneading regulation plate 27 of the base body 14 , the lower kneading massage arm 23 is entrained with the lower kneading inclined boss member 22 . Rotation is restricted. On the other hand, the lower kneading restricting portion 24 (lower kneading restricting plate 27) does not restrict swinging of the lower kneading massage arm 23 along the horizontal direction. Therefore, by providing the lower kneading restricting portion 24 (lower kneading restricting member 26 and lower kneading restricting plate 27), the lower kneading massage arm 23 can move in the left-right direction while being restricted from rotating around the axis pointing in the left-right direction. Swing becomes possible.

That is, in the massage mechanism of the lower kneading massaging member 16 described above, the rotary motion of the rotating shaft 19 rotating around the axis pointing in the left-right direction is controlled by the lower kneading inclined boss member 22, the lower kneading massage arm 23, the lower kneading restrictor 24, And the conversion mechanism using the lower kneading restricting plate 27 converts the translational motion along the left-right direction, thereby making it possible to swing the lower kneading massaging member 16 in the left-right direction.

In addition, in the left lower kneading massaging member 16 and the right lower kneading massaging member 16 described above, the inclination directions of the lower kneading inclined cam surfaces formed on the lower kneading inclined boss member 22 are opposite to each other. mirror image on the left and right). That is, when the lower kneading massage arm 23 provided on the left lower kneading massaging member 16 swings leftward, the right lower kneading massaging member 16 tilts the lower kneading inclined cam surface in the opposite direction. Therefore, the lower kneading massage arm 23 swings to the right, and the pair of left and right lower kneading massage members 16, 16 swing away from each other. In this manner, the pair of left and right lower kneading massaging members 16, 16 repeats the movement toward and away from each other along the left-right direction, and the treatment area positioned between the pair of left and right lower kneading massage members 16, 16 It is possible to perform a kneading massage.

On the other hand, a lateral kneading massaging member 17 is provided further outside in the width direction of the pair of left and right lower kneading massaging members 16, 16 on the rotating shaft 19 described above. The lateral kneading massaging members 17 are also arranged in pairs on the left and right like the lower kneading massaging members 16.例文帳に追加The massaging mechanisms of these lateral kneading massaging members 17 are also configured to swing along the left-right direction by converting the rotational driving force of the rotating shaft 19 by a conversion mechanism similar to that of the lower kneading massaging members 16 . That is, the lateral kneading massaging member 17 includes a lateral kneading inclined boss member 28, a lateral kneading massage arm 32, a lateral kneading inclined cam surface, a lateral kneading regulation portion 44 (lateral kneading regulation member 29, a lateral kneading regulation plate 30), and a lateral kneading body. A treatment element 31 is provided. This lateral kneading massaging member 17 differs from the lower kneading massaging member 16 described above in that the inclination direction of the lateral kneading inclined cam surface is opposite to the inclination direction of the lower kneading inclined cam surface (left and right mirror image). ).

For example, when focusing on the left lower kneading massaging member 16, if the inclination direction of the lower kneading inclined cam surface is inclined in the direction in which the lower kneading massage arm 23 swings rightward, the same left lateral kneading The inclination direction of the lateral kneading inclined cam surface provided on the massaging member 17 is inclined in the direction in which the lateral kneading massage arm 32 swings leftward. Further, when the inclination direction of the lower kneading inclined cam surface is inclined in the direction in which the lower kneading massage arm 23 rocks leftward, the lateral kneading inclined cam surface provided on the same left lateral kneading massaging member 17 is inclined in the direction in which the lateral kneading massage arm 32 swings rightward.

In this manner, the lateral kneading massaging members 17 repeatedly rock in the opposite direction to the lower kneading massaging members 16, so that the lateral kneading massaging members 17 and the lower kneading massaging members 16 adjacent to each other move closer together. By repeating the separating motion, it is possible to perform pinching massage on the treatment portion positioned between the two massaging members.
Note that the lateral kneading massage arm 32 described above also has a bifurcated structure in the same manner as the lower kneading massage arm 23 . Of the bifurcated lateral kneading massage arms 32, the forwardly extending front arm member 32F and the rearwardly extending rear arm member 32R have substantially the same tip height. That is, in the case of the first embodiment, by forming the rear arm member 32R to be longer than the front arm member 32F, the front side massaging treatment element 31 and the rear side side massaging treatment element 31 have substantially the same height. I'm trying to be.

Therefore, when the seat massaging mechanism 6 is moved in the front-rear direction by the seat massaging movement mechanism 33 of the first embodiment, the front lower massaging treatment elements 23 and the rear lower massaging treatment elements 23 are almost at the same height. while maintaining the front side massaging treatment element 31 and the rear side lateral massaging treatment element 31 at substantially the same height. become.

A base body 14 on which the seat massaging mechanism 6 is mounted is provided below the seat massaging mechanism 6 described above. The base body 14 is provided with a seat massaging movement mechanism 33 for moving the base body 14 on which the seat massaging mechanism 6 is mounted in the front-rear direction.

Specifically, in the case of the first embodiment, the traveling gear 36 is arranged at the rear portion of the base body 14 and the slider is arranged at the front portion of the base body 14 . The slider is fitted in a slide groove formed on the upper side of the seat guide rail 7 so as to be parallel to the seat guide rail 7, and guides the base body 14 along the direction in which the slide groove is formed. It is possible. That is, the base body 14 is supported by two points, the traveling gear 36 on the rear side and the slider on the front side, and is movable in the front-rear direction while maintaining a stable posture.

In the seat massaging movement mechanism 33 of the first embodiment, the traveling gear 36 is provided on the rear side of the base body 14. And so on.
In the first embodiment, the traveling motor 34 described above is arranged on the left side of the seat kneading driving section 18 in the base body 14 . The rotational driving force of the travel motor 34 is input to the travel shaft 35 located behind the travel motor 34 via the reduction mechanism 45 . In addition, the traveling shaft 35 described above is arranged behind the rotating shaft 19 so as to be parallel to the rotating shaft 19 (with the axis centered in the left-right direction). A rotational driving force of a traveling motor 34 is input to the middle side of the traveling shaft 35 in the left-right direction, and the traveling shaft 35 is rotatable about the axis facing in the left-right direction using this rotational driving force. Further, the traveling gears 36 are provided at both left and right ends of the traveling shaft 35, respectively. These traveling gears 36 (pinion gears) are provided so as to protrude outward in the width direction from the left and right ends of the base body 14, and mesh with rack gears 37 provided on the seat portion guide rails 7 from above. It is configured.

Therefore, the lower kneading massage arm 23 and the lateral kneading massage arm 32 attached around the rotating shaft 19 are also arranged so as to protrude upward from the upper frame member. Therefore, when the seat massaging mechanism 6 exists at the position shown in FIG. 4, the user's treatment area can be reliably massaged using the lower kneading massage arm 23 and the lateral kneading massage arm 32 .

On the other hand, as shown in FIG. 5, when the running gear 36 is rotated to move the position of the running gear 36 to the middle of the seat guide rail 7 in the front-rear direction, the side-kneading massage arms 32 move toward the upper frame. The lower kneading massage arm 23 exists at a position higher than the members, but the lower kneading massage arm 23 exists at the same height as or slightly higher than the upper frame member. As a result, while pressing the lower kneading treatment element 25 provided at the tip of the lower kneading massage arm 23 against the treatment area such as the thigh from below, the lateral kneading treatment element 31 provided at the tip of the lateral kneading massage arm 32 is widened. It is possible to perform treatment by pressing from the outside of the direction.

Further, as shown in FIG. 6, when the running gear 36 is rotated to move the position of the running gear 36 to the rear end of the seat guide rail 7, the lower kneading massage arm 23 is positioned further than the upper frame member. come to exist in a lower position. Further, the lateral kneading massage arm 32 is located at a position lower than the seat surface when considering the thickness of the cushion material. As a result, the lower kneading treatment element 25 provided at the tip of the lower kneading massage arm 23 and the lateral kneading treatment element 31 provided at the tip of the lateral kneading massage arm 32 can be accommodated below the seat surface. Therefore, it is possible to store the massage mechanism at a position away from the seat surface (a low position where the user does not feel discomfort even when seated).

As described above, if the seat guide rails 7 are arranged in a substantially straight line inclined toward the rear and downward, the seat massaging mechanism 6 can be moved rearward along the seat guide rails 7 to perform the seat massage. It becomes possible to accommodate the mechanism 6 under the seat surface. Further, if the seat portion guide rail 7 can be formed in a substantially straight shape, the manufacturing cost of the parts can be reduced compared to the conventional chair-type massage machine 1 that is curved, and the chair-type massage machine can be manufactured at a lower cost. The price of the machine 1 can be reduced.

By the way, as described above, in the chair-type massage machine 1 of this embodiment, the lower kneading massage arms 23 of the seat massaging mechanism 6 are directed toward the front side and the rear side of the rotation shaft 19 with the rotation shaft 19 as a reference. It has a structure that extends the tip horizontally, so that the thickness along the vertical direction can be reduced. By adopting the lower kneading massage arm 23 having a thin vertical thickness, the seat massaging mechanism 6 can be guided to the rear end of the seat guide rail 7 and the back massaging mechanism 8 can be guided to the lower end of the back guide rail 9. When guided and positioned, the lower kneading massaging member 16 of the seat massaging mechanism 6 is positioned further below the back massaging mechanism 8 located at the lower end of the back guide rail 9, in other words, further below the back massaging member 38. It is possible to As a result, it is possible to compactly accommodate the lower kneading massaging member 16 in the limited space provided below the back massaging mechanism 8 .

Further, as shown in FIGS. 7 and 8, the lateral kneading massage arm 32 of the lateral kneading massaging member 17 is significantly different in shape from the lower kneading massaging arm 23 of the lower kneading massaging member 16 . That is, the lateral kneading massage arms 32 provided on the lateral kneading massage member 17 are curved so as to swell outward in the width direction from the left and right ends of the base body 14, and then are three times as large as the lower kneading massage arms 23. It is formed in a shape that rises upwards to a height of about. If the lateral kneading massage arms 32 are formed in such a shape that rises greatly upward, the position of the lateral kneading treatment elements 31 provided at the tips of the lateral kneading massage arms 32 can be made higher than the position of the lower kneading treatment elements 25. It is possible to perform pressure massage so as to press the treatment part such as the thigh downward from above.

Further, if the lateral kneading massage arms 32 are curved so as to swell outward in the width direction, the seat massaging mechanism 6 is guided to the rear end of the seat guide rail 7, and the back massaging mechanism 8 is guided to the back guide rail. 9, the lateral massaging member 17 of the seat massaging mechanism 6 overlaps the back massaging mechanism 8 located at the lower end of the back guide rail 9 in the side view further outside in the width direction. It is possible to position them in an (overlapping) situation (see FIG. 6).

That is, as shown in FIG. 8, in the chair-type massage machine 1 of the present embodiment, when the seat massaging mechanism 6 is moved to the rear end of the seat guide rail 7, the back massaging mechanism 8 of the back massaging mechanism 40 When viewed from the side, the lateral massaging treatment element 31 is located outside the back massaging element 40 in the width direction, and the lower massaging massaging element 25 is located below the back massaging element 40, so that the lateral massaging massaging element 31 and the back massaging element are positioned. The lower massaging treatment element 25 and the back treatment element 40 do not interfere positionally.

Therefore, the lateral kneading massaging member 17 and the lower kneading massaging member 16, which are easy to take up space, can be moved from the seat surface where the accommodation space is limited, even though the massage mechanism capable of mechanically treating the treatment part is movable. It can be stored in a remote location.
Further, the above-described lateral kneading massage arms 32 extend forward and rearward with respect to the rotating shaft 19 in the same manner as the lower kneading massage arms 23. A lateral kneading treatment element 31 is formed. These front and rear lateral massaging treatment elements 31 are arranged at a distance from each other, and are movable along the seat guide rails 7 while maintaining the same height.

If such a lateral kneading massaging member 17 is provided, even if the lateral kneading massage mechanism is moved along the seat guide rail 7, the height and positional relationship of the lateral kneading treatment elements 31 will not change, and the massage from the buttocks will be performed. It is possible to perform the treatment by bringing the lateral massaging treatment element 31 into contact with the treatment part up to the thigh without fail.
"Second Embodiment"
Next, the chair type massage machine 1 of 2nd Embodiment is demonstrated.

As shown in FIG. 10, in the chair-type massage machine 1 of the second embodiment, the lateral kneading massage member 17 is divided into two upper and lower members, and the upper end side is attached to the lower end side so as to be elastically displaceable in the left-right direction. The lateral kneading massaging member 17 expands or narrows in the left-right direction according to the user's body type, thereby enabling good massage for users of various body types.

For example, when a user with a large figure sits on the seat portion 2, treatment portions such as the thighs are located outside in the left-right direction. In order to deal with such treatment areas, it is preferable to shift the position of the lateral kneading massaging member 17 outward in the left-right direction. However, if the lateral kneading massaging member 17 is fixed in the left-right direction, such movement of the lateral kneading massaging member 17 becomes difficult. However, if the lateral kneading massaging members 17 are deformed so as to spread outward in the width direction against the elastic force as shown in the second embodiment, the lateral kneading massaging members 17 can also be applied to the treatment areas located on the outer side in the left-right direction. Since the 31 can be reliably pressed, even a large user with a width in the left-right direction can reliably treat the treatment portion.

On the other hand, when a user with a small figure sits on the seat portion 3, an elastic force is applied to the lateral kneading massaging members 17 so that the intervals between the lateral kneading massagers 31 narrow inward in the width direction. When the position of the treatment section is located inside in the left-right direction, the lateral kneading massaging member 17 naturally moves inward in the left-right direction due to its elastic force. Therefore, since the lateral massaging treatment element 31 can be reliably pressed against the treatment area such as the user's thigh, even a user with a small figure can reliably treat the treatment area.

Specifically, the lateral kneading massaging member 17 of the second embodiment described above includes a lower massaging body 50 arranged on the lower side (driving side) and an upper massaging body 51 arranged above the lower massaging body 50. , a connecting portion 53 for connecting the upper massaging body 51 to the lower massaging body 50 so as to be swingable about an axis (swing shaft 52) facing in the front-rear direction; and an elastic member 54 that biases inward. Next, the lower massaging body 50, the upper massaging body 51, the connecting portion 53, and the elastic member 54 that constitute the lateral kneading massaging member 17 of the second embodiment will be described.

The lower massaging body 50 is arranged further outside in the width direction of the pair of left and right lower massaging members 16, 16 on the rotating shaft 19 described above. A pair of left and right lower massaging bodies 50 are arranged as in the first embodiment. These lower massaging bodies 50 also convert the rotational driving force of the rotating shaft 19 by the same conversion mechanism as the lower kneading massaging member 16 (horizontal kneading inclined boss member 28, lateral kneading inclined cam surface, and lateral kneading restricting part 44). By doing so, it is configured to swing along the left-right direction.

In addition, the lower massaging body 50 is formed in a shape that rises upward to the same height as the lower kneading massaging arm 23, and the upper end is shaped such that the central side in the front-rear direction protrudes upward. . A through hole 55 passing through the lower massaging body in the front-rear direction is formed in this upwardly projecting portion, and a swing shaft 52 is provided so as to pass through the through hole 55 in the front-rear direction.

The upper massaging body 51 is formed in such a shape that it curves so as to swell greatly outward in the width direction from the upper end of the lower massaging body 50 and then rises upward to a height about three times that of the lower massaging arm 23 . ing.
Specifically, the upper massaging body 51 is a member that is bifurcated into a front portion and a rear portion and has a substantially V shape when viewed from the side. The lower part of the upper massaging body 51 is formed in a gate shape in which the middle side in the front-rear direction is concave upward in a rectangular shape. A communication hole 56 that penetrates the upper massaging body 51 in the front-rear direction is formed in the gate-shaped portion. there is

The connecting portion 53 has the through hole 55 of the lower massaging body 50 described above, the communicating hole 56 of the upper massaging body 51 , and the swing shaft 52 that communicates the through hole 55 and the communicating hole 56 . The swing shaft 52 is arranged to face in the front-rear direction, and connects the upper massaging body 51 to the lower massaging body 50 so as to be swingable around the front-rear direction axis.
The elastic member 54 is a member that biases the upper massaging body 51 toward the inside in the width direction with respect to the lower massaging body 50, and in this embodiment, a coil spring is used. This coil spring (elastic member 54) is arranged between the through hole 55 of the lower massaging body 50 and the communication hole 56 of the upper massaging body 31, and is arranged so as to wind around the swing shaft 52. Thus, an urging force (elastic force) can be generated in a direction that presses the upper massaging body 51 toward the inner side in the width direction with respect to the lower massaging body 50 .

The body shape measurement sensor measures the angle of inclination of the upper massaging body 51 with respect to the lower massaging body 50 (widthwise inner side or The body shape of the user seated on the seat portion 2 is determined by measuring the change in the angle of inclination to the outside.
For example, the lateral kneading massaging member 17 is moved from the front to the rear using the seat guide rail 7 so that the rotational driving force is not transmitted to the lower massaging body 50, in other words, in a state in which the rotation of the rotating shaft 19 is stopped. Let Here, when the seat massaging mechanism 6 is positioned at the front end of the seat guide rail 7, the distance between the lateral massaging members 31 of the left and right lateral massaging members 17 is larger than the lateral size of the user. Consider the case where is widened. In this case, the upper massaging body 51 does not contact the treatment area, and the upper massaging body 51 is biased most inward in the left-right direction due to the elastic force of the elastic member 54 .

However, when the seat massaging mechanism 6 is further moved to the rear end side of the seat guide rail 7, the lateral size of the user and the interval between the lateral kneading treatment elements 31 of the left and right lateral kneading massaging members 17 eventually become equal. Then, the upper massaging body 51 hits the treatment area, and the upper massaging body 51 begins to swing outward in the left-right direction against the elastic force of the elastic member 54 . By measuring the rocking movement of the upper massaging body 51 with a body type measuring sensor, the user's body type (the size in the left-right direction) can be determined.

It should be noted that the embodiments disclosed this time should be considered as examples and not restrictive in all respects. In particular, matters not explicitly disclosed in the embodiments disclosed this time, such as operating conditions, operating conditions, various parameters, dimensions of components, weights, volumes, etc. Instead, a value that can be easily assumed by a person skilled in the art is adopted.

For example, in the present embodiment, a rack-and-pinion mechanism is used as a specific configuration of the seat guide rails 7, but other moving mechanisms may be used. Similarly, a rack-and-pinion mechanism may be employed as a specific configuration of the back guide rail 9, or another movement mechanism such as a shaft mechanism having a feed screw formed on the outer peripheral surface may be used.
In addition, regarding the lower massaging treatment element 25 and the lateral massaging massaging element 31, by rocking the lower massaging massaging element 25 and the lateral massaging massaging element 31 in the horizontal direction in the same phase, the lower part and the lateral part of the user's buttocks are moved. can be effectively massaged. On the other hand, when the lower kneading treatment element 25 and the lateral kneading treatment element 31 are rocked in the opposite phase in the lateral direction, the treatment part is massaged so as to be sandwiched between the lower kneading treatment element 25 and the lateral kneading treatment element 31. is also possible.

Further, in the present embodiment, a two-motor type including the drive motor 18 as the seat massaging drive unit and the traveling motor 34 for moving the seat massaging mechanism 6 back and forth is disclosed. , 34 can be shared to form a one-motor system.
