(An example of a form that a massage machine can take)
[1] One embodiment of a massage machine according to the present invention includes a footrest that supports a foot, a treatment portion that is provided on the footrest so as to massage the sole, and a drive portion that drives the treatment portion. The treatment unit includes a rotation roller that is rotatable with respect to the footrest and a plurality of projections provided on an outer peripheral surface of the rotation roller, and the plurality of projections can treat the inside of a sole. It includes a first convex portion and a second convex portion capable of treating the outside of the sole, and the first convex portion is higher than the second convex portion.

  As for the shape of the sole of a general person, the inside of the sole is recessed with respect to the outside. On the other hand, according to the massage machine, the relationship between the height of the first convex portion and the height of the second convex portion is set so as to follow the shape of the sole of a general person as described in [1]. Yes. For this reason, compared with the case where the 1st convex part is lower than the 2nd convex part, or it is substantially the same height as the 2nd convex part, the 1st convex part is strongly inside the sole. Contact and massage according to the shape of the sole is provided. For this reason, a preferable massage feeling is given to the sole.

[2] According to an example of the massage machine, the first convex portion and the second convex portion have different positions in the circumferential direction of the rotating roller.
When the inside and outside of the sole are massaged simultaneously, the massage feeling given to the sole is reduced. This is related to the fact that only one massage, which has a strong stimulus to the sole, gives a strong impression to the user. That is, the other massage, which is weak on the sole, does not give a strong impression to the user. On the other hand, according to the massage machine, the inner side and the outer side of the sole are massaged alternately, so that a strong impression is given to the user regardless of whether the first convex portion or the second convex portion is massaged. For this reason, a preferable massage feeling is easily given to the sole.

  [3] According to an example of the massage machine, the outer peripheral surface of the rotating roller includes a curved surface portion where the convex portion does not exist, and the circumferential length of the curved surface portion is the circumferential direction of the first convex portion. And a length in the circumferential direction of the second convex portion.

  When a massage that continuously gives a stimulus is applied to the sole of the foot, the user gets used to the stimulus and it is difficult to give a strong impression to the user. On the other hand, according to the massage machine, since the curved surface portion is provided on the outer peripheral surface of the rotary roller, the sole is massaged with a predetermined interval. For this reason, a strong impression is given to the user and a preferable massage feeling is easily given to the sole.

  [4] According to an example of the massage machine, in addition to the first treatment part which is the treatment part, a part of the sole different from the part to be massaged by the first treatment part is massaged. A second treatment unit is further provided.

[5] According to an example of the massage machine, the drive unit includes a relative drive unit that relatively moves the first treatment unit and the second treatment unit in the front-rear direction of the foot.
[6] According to an example of the massage machine, the drive unit further includes a support shaft that supports the rotating roller, and a motor that rotates the support shaft, and the relative drive unit is eccentric with respect to the support shaft. A rotating eccentric shaft, and a link connecting the eccentric shaft and the second treatment portion so that the second treatment portion moves relative to the first treatment portion at least in the front-back direction of the foot. .

  [7] According to an example of the massage machine, the relative driving unit is configured such that one of the first convex portion and the second convex portion and the second treatment portion are closest to each other in the front-rear direction of the foot. In some cases, the second treatment section is configured to be farthest from the rotating roller.

  When the second treatment portion is closest to the rotating roller when one of the first protrusion and the second protrusion and the second treatment portion are closest, the first treatment portion and the protrusion are It is necessary to lengthen the link so that it does not touch. For this reason, when a 2nd treatment part leaves | separates most from a rotation roller, the space | interval of a 2nd treatment part and a rotation roller becomes wide. This may hinder downsizing of the massage machine. On the other hand, since the relative drive unit is configured as described in [7] above, the massage machine can be easily downsized.

  [8] According to an example of the massage machine, the first treatment part can massage a portion of the sole around the arch, and the second treatment part is around a finger base of the sole. Can be massaged.

That is, the second convex portion 232 is provided between the first convex portion 231 and the third convex portion 233 in the axial direction of the rotating roller 221. Each of the convex portions 231 to 233 has, for example, a bar shape and extends upward from the support base 234.

  The height of the first convex portion 231 is lower than that of the second convex portion 232 and the third convex portion 233. The height of the second convex part 232 is higher than that of the first convex part 231 and the third convex part 233. The third convex part 233 is higher than the first convex part 231 and lower than the second convex part 232. The relationship between the heights of the convex portions 231 to 233 is set so as to follow the shape of the thumb ball, the little finger ball, and the range between the thumb ball and the little finger ball on the sole. For this reason, it is easy to give a preferable massage feeling to the part of the sole around the base of the finger.

  The ottoman 100 further includes a first detection unit 251 and a second detection unit 252. The function of the first detection unit 251 is to detect the rotation state of the rotating roller 221.

The first protrusion 222 is higher than the second protrusion 223. Specifically, the first distance CH1, which is the distance between the outer peripheral surface of the rotating roller 221 and the tip of the first convex portion 222, is the distance between the outer peripheral surface of the rotating roller 221 and the tip of the second convex portion 223. Is longer than the second distance CH2. For this reason, the 1st convex part 222 is exposed from the recessed part 133A (refer FIG. 3) of the footrest 130 rather than the 2nd convex part 223. FIG.

  As for the shape of the sole of a general person, the inside of the sole is recessed with respect to the outside. On the other hand, the relationship between the height of the first convex portion 222 and the height of the second convex portion 223 is set so as to conform to the shape of a general human sole. For this reason, compared with the case where the 1st convex part 222 is lower than the 2nd convex part 223, or it is substantially the same height as the 2nd convex part 223, the 1st convex part 222 is a sole. A massage according to the shape of the sole is provided. For this reason, a preferable massage feeling is given to the sole.

  The curvatures of the first convex portion 222 and the second convex portion 223 are different from each other. In one example, the second convex portion 223 has a larger curvature than the first convex portion 222. For this reason, the 2nd convex part 223 can give a stronger stimulus to the sole than the 1st convex part 222 at the time of contact with the sole.

  The relative drive unit 243 includes an eccentric shaft 243A and a link 243B. The eccentric shaft 243 </ b> A is provided at a position shifted from the rotation center of the rotation roller 221 on the other side surface of the rotation roller 221, for example. The eccentric shaft 243 </ b> A rotates around the support shaft 241 together with the rotating roller 221 when the support shaft 241 rotates. For this reason, the position of the eccentric shaft 243A with respect to the rotating roller 221 moves in the front-rear direction and the height direction of the foot. That is, the eccentric shaft 243A rotates eccentrically with respect to the support shaft 241.

  The function of the link 243B is to convert the eccentric motion caused by the rotation of the eccentric shaft 243A into a linear motion along the front-rear direction of the foot. The link 243B connects the eccentric shaft 243A and the support base 234 of the second treatment unit 230 so that the second treatment unit 230 moves relative to the first treatment unit 220 in the front-rear direction of the foot. The eccentric shaft 243A and the link 243B are connected to rotate relative to each other. For this reason, when the eccentric shaft 243A rotates eccentrically, the link 243B forms a linear motion along the front-rear direction of the foot, and the second treatment unit 230 moves in the front-rear direction of the foot with respect to the first treatment unit 220. .

  Further, since the position of the eccentric shaft 243A with respect to the rotating roller 221 moves also in the height direction of the foot by rotating the support shaft 241, the connecting portion of the link 243B and the eccentric shaft 243A also moves in the height direction of the foot. To do. For this reason, the 2nd treatment part 230 swings so that the position of the front-end | tip of each convex part 231-233 may change in the height direction of a leg | foot.

  The first treatment unit 220 and the second treatment unit 230 are arranged such that the positions of the tips when the tips of the convex portions 222 and 223 of the first treatment unit 220 are in contact with the soles of the second treatment unit 230. It is provided in the footrest 130 (refer FIG. 3) so that the front-end | tip of each convex part 231-233 may become higher than the position of the front-end | tip when contacting a sole. For this reason, each convex part 222,223 of the 1st treatment part 220 contacts the cover 136 (refer FIG. 3) more strongly than each convex part 231-233 of the 2nd treatment part 230. FIG.

  When the first convex portion 222 of the first treatment portion 220 and the second treatment portion 230 are closest to each other in the front-rear direction of the foot, the relative drive portion 243 moves the second treatment portion 230 from the rotating roller 221 most. It is comprised so that it may leave | separate (refer FIG. 10). That is, when the position of the eccentric shaft 243A with respect to the rotation roller 221 takes the frontmost position in the front-rear direction of the foot, the position where the first convex portion 222 faces the second treatment portion 230 in the circumferential direction of the rotation roller 221 is determined. take.

  According to the structure of the relative drive part 243, the following effect is acquired. When the second treatment portion 230 and the first convex portion 222 are closest to each other, and the second treatment portion 230 is closest to the rotating roller 221, the second treatment portion 230 and the first convex portion 222 are It is necessary to lengthen the link 243B so as not to contact. For this reason, when the 2nd treatment part 230 leaves | separates most from the rotation roller 221, the space | interval of the 2nd treatment part 230 and the rotation roller 221 becomes wide. This may hinder downsizing of the massage machine. On the other hand, since the massage machine 1 includes the relative drive unit 243 as described above, the massage machine 1 can be easily downsized.

  The relative drive unit 243 is configured such that the second treatment unit 230 is closest to the rotating roller 221 when the curved surface portion 224 and the second treatment unit 230 are closest to each other in the front-rear direction of the foot (FIG. 8). reference). That is, when the position of the eccentric shaft 243A with respect to the rotation roller 221 takes the most rearward position in the front-rear direction of the foot, a position where a part of the curved surface portion 224 faces the second treatment unit 230 in the circumferential direction of the rotation roller 221 take. For this reason, compared with the case where the 2nd treatment part 230 approaches the rotation roller 221 when the 2nd treatment part 230 and each convex part 222,223 come closest, it is easy to miniaturize the massage machine 1. .

  The relative drive unit 243 is configured such that the sole and the curved surface part 224 come into contact with each other when the second treatment unit 230 moves rearward in the front-back direction of the foot. That is, in the process in which the position of the eccentric shaft 243A with respect to the rotating roller 221 moves from the front to the rear in the front-rear direction of the foot, the curved surface portion 224 takes a position facing the sole in the circumferential direction of the rotating roller 221. Specifically, in the process in which the rotating roller 221 rotates from the state shown in FIG. 11 to the state shown in FIG. 8, the state where the curved surface portion 224 and the sole contact is maintained.

The operation of the sole treatment unit 210 will be described with reference to FIGS.
The rotation roller 221 sequentially forms a first rotation state, a second rotation state, a third rotation state, and a fourth rotation state by rotating the support shaft 241.

  As shown in FIG. 8, the rotating roller 221 is in the first rotating state, which is the initial state, for example, the position of the eccentric shaft 243A with respect to the rotating roller 221 takes the rearmost position in the front-back direction of the foot. In the first rotation state, the curved surface portion 224 of the first treatment portion 220 and the convex portions 231 to 233 of the second treatment portion 230 are in contact with the soles. For this reason, when the user who uses the massage machine 1 has placed his / her foot on the footrest 130, it is stronger against the sole as compared with the case where the convex portions 222 and 223 of the first treatment unit 220 are in contact with the sole. Hard to be stimulated. Then, the rotation roller 221 starts to rotate from the first rotation state as the support shaft 241 rotates.

  As shown in FIG. 9, the rotation roller 221 takes the highest position in the foot height direction, for example, the position of the eccentric shaft 243A with respect to the rotation roller 221 as the second rotation state. That is, the second rotation state is a state in which the rotation roller 221 in the first rotation state is rotated 90 ° counterclockwise in the side view shown in FIG. In the process of the rotation roller 221 shifting from the first rotation state to the second rotation state, the first convex portion 222 of the first treatment unit 220 and the convex portions 231 to 233 of the second treatment unit 230 Contact with. For this reason, the inside of a sole is massaged by the 1st convex part 222, and the site | part around the base of the finger of the sole is massaged by the convex parts 231-233 of the 2nd treatment part 230. FIG.

  As shown in FIG. 10, the rotation roller 221 is in the third rotation state, for example, the position of the eccentric shaft 243 </ b> A with respect to the rotation roller 221 takes the foremost position in the front-back direction of the foot. That is, the third rotation state is a state in which the rotation roller 221 in the second rotation state is rotated 90 ° counterclockwise in the side view shown in FIG. In the process in which the rotation roller 221 shifts from the second rotation state to the third rotation state, the second protrusion 223 of the first treatment part 220 and the protrusions 231 to 233 of the second treatment part 230 are the soles. Contact with. For this reason, the outer side of the sole is massaged by the second convex part 223, and the part of the sole around the base of the finger is massaged by the convex parts 231 to 233 of the second treatment part 230.

  As shown in FIG. 11, the rotation roller 221 takes the lowest position in the foot height direction, for example, the position of the eccentric shaft 243 </ b> A with respect to the rotation roller 221 as the fourth rotation state. That is, the fourth rotation state is a state in which the rotation roller 221 in the third rotation state is rotated 90 ° counterclockwise in the side view shown in FIG. In the process in which the rotation roller 221 shifts from the third rotation state to the fourth rotation state, the curved surface part 224 of the first treatment part 220 and the convex parts 231 to 233 of the second treatment part 230 are in contact with the soles. To do.

  When the curved surface part 224 of the first treatment part 220 is in contact with the sole, the first treatment part 220 does not substantially massage the sole. In this state, when each convex part 231-233 of the 2nd treatment part 230 massages a sole, a user learns only the massage feeling given to a sole by each convex part 231-233.

  For example, when the soles are massaged by the projections 231 to 233 of the second treatment unit 230 in a state where the projections 222 and 223 of the first treatment unit 220 are in contact with the soles, The force applied to the sole by the convex portions 222 and 223 of the treatment section 220 is stronger than that of the second treatment section 230, and the user has a strong impression of the massage performed on the sole by the second treatment section 230. Hateful. On the other hand, in the fourth rotation state shown in FIG. 11, since the sole is not substantially massaged by the first treatment unit 220, the user can put the sole on the sole by the convex portions 231 to 233 of the second treatment unit 230. It is easy to get a strong impression about the massage given. For this reason, a favorable massage feeling is given to the site | part around the base of the finger | toe among soles.

  Then, the rotation roller 221 rotates 90 ° counterclockwise from the fourth rotation state in the side view shown in FIG. 11, and shifts to the first rotation state shown in FIG. In the process in which the rotation roller 221 shifts from the fourth rotation state to the first rotation state, the curved surface portion 224 of the first treatment portion 220 and the convex portions 231 to 233 of the second treatment portion 230 are in contact with the soles. To do. At this time, since each convex part 231-233 contacts a sole, moving back in the front-back direction of a foot, it massages so that the site | part around the base of a finger in a sole may be scratched. For this reason, a user tends to receive a stronger impression about the massage given to the sole by each convex part 231-233.

  As described above, the rotation roller 221 repeatedly forms the first rotation state, the second rotation state, the third rotation state, and the fourth rotation state as the support shaft 241 rotates. And the operation | movement of the massage machine 1 stops after the power supply of the massage machine 1 is set to OFF, after the rotation roller 221 forms the 1st rotation state which is an initial state. In addition, when the support shaft 241 rotates so that the rotation roller 221 rotates clockwise in the side view illustrated in FIG. 8, the rotation roller 221 has a first rotation state, a fourth rotation state, and a third rotation state. And the second rotation state is repeatedly formed.

  With reference to FIG. 12 and FIG. 13, the relationship between the sole treatment unit 210 and the sole when the foot is arranged on the footrest 130 will be described. 12 shows the relationship with the sole when the second treatment part 230 takes the most forward position in the front-rear direction of the foot, and FIG. 13 shows the second treatment part 230 in the rearward direction of the foot. The relationship with the sole when taking the position of is shown.

  The 1st convex part 222 of the 1st treatment part 220 contacts the site | part around the arch in a sole by the rotation roller 221 rotating. For this reason, the part around the arch in the sole is massaged by the first convex portion 222. The 2nd convex part 223 of the 1st treatment part 220 contacts a part outside the arch in a sole by rotation of rotation roller 221. For this reason, the part of the sole outside the arch is massaged by the second convex portion 223. It should be noted that the position of the sole where the first convex portion 222 contacts and the position of the sole where the second convex portion 223 contacts are substantially the same in the front-rear direction of the sole.

  As FIG. 12 shows, the 2nd treatment part 230 contacts the site | part around the base of the finger | toe of the sole. Specifically, the first convex part 231 contacts the part of the sole around the base of the thumb, and the second convex part 232 contacts the part of the sole of the index finger and the base of the middle finger. The third convex portion 233 comes into contact with a portion of the sole around the base of the ring finger and little finger. For this reason, the site | part around the base of each finger | toe of a sole is massaged by each convex part 231-233.

  As FIG. 13 shows, the 2nd treatment part 230 contacts the site | part behind the base of the finger | toe among the soles. Specifically, the first convex portion 231 is in contact with a portion of the sole around the thumb ball, and the second convex portion 232 is a range between the thumb ball and the little finger ball of the sole. The third convex portion 233 comes into contact with the portion of the sole around the little ball. For this reason, a part of the range between a thumb ball, a little finger ball, and a thumb ball and a little finger ball is massaged by each convex part 231-233. In addition, the site | part massaged by each convex part 231-233 depends on the shape of a leg | foot, a magnitude | size, etc.

FIG. 14 shows a state where the foot treatment unit 300 is deployed.
The foot treatment part 300 includes a first treatment member 311, a second treatment member 312, and a support part 320. The function of the first treatment member 311 is to intensively massage around the heel located inside the foot. The function of the second treatment member 312 is to intensively massage around the heel located outside the foot.

  It was confirmed that a comfortable massage feeling was given to the feet by massaging around the heel. For this reason, when the surroundings of the heel are massaged by the treatment members 311 and 312, a comfortable massage feeling is given to the feet. On the other hand, when another part close to the periphery of the heel is massaged simultaneously with the periphery of the heel, the massage feeling felt by the user is lowered. This is related to the fact that when a plurality of parts close to each other are massaged at the same time, the feeling of massage given to each part tends to blur. In addition, when another part is massaged at the same time in addition to the periphery of the heel by the foot treatment unit 300, the force applied by the foot treatment unit 300 is dispersed, and the massage feeling applied to the periphery of the heel is reduced. According to the foot treatment unit 300 shown in FIG. 14, since the surroundings of the heel are massaged intensively by the treatment members 311 and 312, a preferable massage feeling is given to the heel.

An example of the material of each of the treatment members 311 and 312 is TPV (Thermo-Plastic-Vulcanizates) resin. Each treatment member 311, 312 is supported by the support part 320.
The function of the support part 320 is to support each treatment member 311, 312 so that the strength of massage by each treatment member 311, 312 can be adjusted. The support part 320 includes a first side part 321, a second side part 322, and an intermediate part 323. The function of the first side 321 is to support the first treatment member 311. The function of the second side 322 is to support the second treatment member 312. The intermediate part 323 is a part connected to the first side part 321 and the second side part 322.

  The support part 320 includes an airbag. In one example, the support part 320 forms an airbag. For this reason, compared with the case where the support part 320 and an airbag are provided separately, the number of parts which comprise the massage machine 1 is reduced. The support part 320 further includes a non-expanding part 323A and an air supply port 323B. The non-expandable portion 323A is a portion of the support portion 320 that does not expand, and is formed, for example, by welding one surface and the other surface of the support portion 320 to each other. The non-expanding part 323A is provided in the intermediate part 323, for example. That is, the intermediate part 323 does not substantially expand.

  The air supply port 323 </ b> B is a hole for supplying air into the support portion 320. The air supply port 323B is provided, for example, in the intermediate portion 323. The air supply port 323 </ b> B is connected to an air pump 340 which is an adjustment unit constituting a part of the massage machine 1. By supplying air from the air pump 340, the first side portion 321 and the second side portion 322 of the support portion 320 are expanded, and the treatment members 311 and 312 are pressed around the heel. That is, the air pump 340 can adjust the strength of the massage by the foot treatment unit 300. The air pump 340 is connected to both the air supply ports 323B of the pair of foot treatment units 300.

  The shape of each of the treatment members 311 and 312 is a curved shape along the periphery of the heel. In this shape, the treatment members 311 and 312 can easily fit around the heel when the foot is placed on the footrest 130 (see FIG. 15). For this reason, each treatment member 311 and 312 and the circumference | surroundings of a heel appropriately contact, and a preferable massage feeling is given to the circumference | surroundings of a heel.

  For example, the first treatment member 311 and the second treatment member 312 have a line-symmetric relationship with respect to the center line in the width direction of the support portion 320. In the example shown in FIG. 14, the first treatment member 311 and the second treatment member 312 are curved so as to form a square shape on the support portion 320. That is, the first treatment member 311 is supported by the support portion 320 so as to massage the water fountain FS (see FIG. 16) around the heel. The second treatment member 312 is supported by the support 320 so as to massage at least one of the personal FB and the lymph node FL (see FIG. 17) around the heel.

  The support part 320 further includes a first fixing part 331, a second fixing part 332, and a third fixing part 333. The function of each fixing part 331 to 333 is to fix the position of the support part 320 with respect to the footrest 130. The first fixing portion 331 and the second fixing portion 332 are provided at the bottom of the intermediate portion 323, for example. The third fixing portion 333 is provided at the bottom of the first side portion 321, for example.

FIG. 15 shows a state where the pair of foot treatment units 300 is attached to the footrest 130.
The support part 320 is attached to the bottom wall 133 of the footrest 130, for example. In one example, the first side portion 321 is provided so as to face the inner wall 131, the second side portion 322 is provided so as to face the outer wall 132, and the intermediate portion 323 faces the back wall 134. Is provided. Each fixing part 331 to 333 is fixed to the bottom wall 133, for example. Thereby, the first side portion 321 and the intermediate portion 323 are not easily displaced with respect to the footrest 130. On the other hand, the second side portion 322 is not fixed to any part of the footrest 130 so that it can be displaced with respect to the footrest 130.

  When a strong force is applied to the heel located on the outside of the foot and the surrounding bone, it is easy for the user to feel uncomfortable. This is related to the fact that the heel located on the outside of the foot and the surrounding bone are likely to feel pain. On the other hand, since the second side portion 322 can be displaced with respect to the footrest 130, even if the second treatment member 312 and the bone of the foot come into contact with each other, the foot moves in response to pain or the like. The position of the second treatment member 312 with respect to the bone is easily shifted. For this reason, the heel and its surrounding bone and the second treatment member 312 are not easily in contact with each other, and the possibility that the user feels uncomfortable is reduced.

  The support part 320 is provided on the footrest 130 so that the first side part 321 overlaps with the inner leg airbag 141 and the second side part 322 overlaps with the outer leg airbag 142, for example. That is, the treatment members 311 and 312 are pressed around the heel by the force of at least two airbags. In the example shown in FIG. 15, a part of the first side part 321 overlaps with the inner leg airbag 141, and a part of the second side part 322 overlaps with the outer leg airbag 142. For this reason, a stronger force can be applied to the periphery of the heel by the treatment members 311 and 312, and massages with various strengths can be provided around the heel depending on the combination of airbags to be inflated.

  The support part 320 is attached to the footrest 130 so that the first treatment member 311 and the second treatment member 312 face each other. Air is supplied from the air pump 340 (see FIG. 14) to the support portion 320 via the air supply port 323B, and the first side member 321 and the second side portion 322 are expanded, so that the first treatment member 311 and the first treatment member 311 2 treatment members 312 are brought close to each other. Therefore, the treatment members 311 and 312 are pressed around the heel.

With reference to FIG. 16 and FIG. 17, the relationship between each treatment member 311 and 312 when a foot | leg is arrange | positioned on the footrest 130 and the circumference | surroundings of a heel is demonstrated.
As FIG. 16 shows, the 1st treatment member 311 contacts the circumference | surroundings of the heel located inside a leg | foot. Specifically, the first treatment member 311 contacts the water fountain FS around the heel located on the inside of the foot. For this reason, the 1st side part 321 (refer FIG. 14) expands, and the circumference | surroundings of the heel including the water fountain FS are massaged by the 1st treatment member 311.

  It was confirmed that if the water fountain FS around the heel is massaged, a more preferable massage feeling is given around the heel located inside the foot. For this reason, when the water fountain FS is massaged by the first treatment member 311, a more preferable massage feeling is given around the heel located on the inner side of the foot.

  As FIG. 17 shows, the 2nd treatment member 312 contacts the circumference | surroundings of the heel located in the outer side of a leg | foot. Specifically, the second treatment member 312 is in contact with the personal FB and the lymph node FL around the heel located outside the foot. For this reason, when the second side portion 322 (see FIG. 14) expands, the second treatment member 312 massages the periphery of the heel including the personal FB and the lymph node FL.

  It was confirmed that if at least one of the personal FB and lymph node FL around the heel is massaged, a more preferable massage feeling is given around the heel located outside the foot. For this reason, since the personality FB and the lymph node FL are massaged by the second treatment member 312, a more preferable massage feeling is given around the heel located outside the foot.

-The structure of the relative drive part 243 can be changed arbitrarily. In the first example, the relative driving unit 243 is configured so that the second treatment unit 230 is located when the first convex portion 222 of the first treatment unit 220 and the second treatment unit 230 are closest to each other in the front-back direction of the foot. Is configured to be closest to the rotating roller 221. In the second example, the relative driving unit 243 moves the second treatment unit 230 when the second convex portion 223 of the first treatment unit 220 and the second treatment unit 230 are closest to each other in the front-back direction of the foot. Is configured to be farthest from the rotating roller 221.
