[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below is an example of a specific embodiment of the present invention, and the configuration of the present invention is not limited to this specific example.

[0021] The massage machine 1 of this embodiment is a shoulder-type massage machine that is worn on the shoulders of the user P and is mainly used to massage the neck, shoulders, etc. of the user P. Note that the massage machine 1 of this embodiment can also massage the waist, legs, etc. of the user P by changing the wearing position.

[0022] As shown in Figs. 1 to 4, the massage machine 1 includes a main body 2, a shoulder strap 3, and a mounting part 4. As shown in Figs. 1 and 2, the main body 2 includes a massage mechanism 5. The massage mechanism 5 is built into the main body 2, and massages the shoulder and surrounding areas to be treated by placing the treatment section 2S of the main body 2 against the shoulder of the user P and driving the massage mechanism 5. The detailed configuration of the massage mechanism 5 will be described later.

[0023] 5 to 7, in this embodiment, the direction corresponding to the front-to-back direction of the user P in a basic posture in which the massager is properly worn on the user P (the direction indicated by arrows X1 and X2 in FIGS. 1 and 4) will be described as the front-to-back direction of the massager 1, the direction corresponding to the left-to-right direction of the user P in the same posture (the direction indicated by arrows Y1 and Y2 in FIGS. 1 to 3) will be described as the left-to-right direction of the massager 1, and the direction corresponding to the up-to-down direction of the user P in the same posture (the direction indicated by arrows Z1 and Z2 in FIGS. 1 to 4) will be described as the up-to-down direction of the massager 1. Furthermore, the massager 1 of this embodiment has many flexibly deformable parts such as the shoulder strap part 3 and the wearing part 4, and the arrangements, extension directions, etc. of these parts will also be described based on the state of the basic posture.

[0024] 1 and 2, the shoulder straps 3 are respectively provided extending from the left and right ends of the main body 2. In other words, the body of the massage machine 1 is configured in a U-shape by the main body 2 and the pair of left and right shoulder straps 3. As a result, when the massage machine 1 is worn by the user P with the left and right shoulder straps 3 hung on the shoulders of the user P, the treatment sections 2S of the main body 2 can be held in appropriate contact with the shoulders and the surrounding treatment areas.

[0025] 1 to 4, the shoulder straps 3 are formed integrally with the main body 2 and extend like legs from the left and right ends of the main body 2. The shoulder straps 3 extend downward and forward from the left and right ends of the main body 2 and are arranged side by side in the left-right direction at a distance wider than the neck of the user P (see FIG. 5).

[0026] The main body 2 and the shoulder strap 3 have an exterior cover and cushioning material. The exterior cover is made of a flexible fabric such as artificial leather or mesh fabric. The cushioning material is made of an elastic material such as urethane. The cushioning material is placed inside the exterior cover, excluding the storage area for the massage mechanism 5 and some areas such as the treatment unit 2S. Therefore, the shoulder strap 3 has shape retention, but can be bent within a predetermined range. In other words, the shoulder strap 3 is bendable. This allows the massage machine 1 to be easily worn by the user P by bending the left and right shoulder straps 3 outward to the left and right (widening the gap between the shoulder straps 3).

[0027] As shown in FIGS. 1, 2, and 5, one of the left and right shoulder straps 3 (the left shoulder strap 3 in this embodiment) has an operating unit C1. The operating unit C1 is connected to the massage mechanism 5 via a control circuit. The user P operates the massage mechanism 5 using the operating unit C1. The massage mechanism 5 is driven by power supplied from an external power source via a power cable. The massage mechanism 5 may also be configured to be driven by power supplied from a battery built into the main body 2 or the shoulder strap 3.

[0028] The massage mechanism 5 can be any mechanism capable of performing various massages, such as kneading massage, grasping massage, and tapping massage, as long as it can appropriately massage the neck, shoulders, etc. of the user P. For example, the massage machine 1 of this embodiment can employ the mechanism disclosed in Japanese Patent Application Laid-Open No. 2018-029722 as the massage mechanism 5. Alternatively, the massage machine 1 of this embodiment may employ the mechanism disclosed in Japanese Patent Application Laid-Open No. 2013-031567 as the massage mechanism 5.

[0029] As shown in FIG. 8 , in this embodiment, the massage mechanism 5 includes a drive unit 50, a first massage mechanism 51, a second massage mechanism 52, and a power transmission mechanism 53. The drive unit 50 generates a rotational drive force. The first massage mechanism 51 performs a first massage (in this embodiment, a kneading massage and a grasping massage) on the treatment area of ​​the user P. The second massage mechanism 52 performs a second massage (in this embodiment, a tapping massage) different from the first massage on the treatment area of ​​the user P. The power transmission mechanism 53 transmits the rotational drive force of the drive unit 50 to both the first massage mechanism 51 and the second massage mechanism 52, or to only the first massage mechanism 51. In other words, the massage mechanism 5 is configured to perform a variety of massages by simultaneously or selectively driving the two massage mechanisms 51 and 52 using a single drive unit 50.

[0030] The massage mechanism 5 has a plurality of kneading treatment elements T1 and gripping treatment elements T2. The first massage mechanism 51 performs a kneading massage by pressing the kneading treatment elements T1 against the treatment area. The first massage mechanism 51 also performs a gripping massage by operating the kneading treatment elements T1 and the gripping treatment elements T2 to pinch the treatment area between them. More specifically, the first massage mechanism 51 operates the kneading treatment elements T1 and the gripping treatment elements T2 to move closer to or farther away from each other, narrowing or widening the distance between the kneading treatment elements T1 and the gripping treatment elements T2. This allows the first massage mechanism 51 to perform a pinching massage (grasping massage) of the treatment area. The second massage mechanism 52 performs a beating massage by operating the kneading treatment elements T1 to hit the treatment area at short intervals.

[0031] By performing the above massage operations, the massage mechanism 5 receives a reaction force from the area to be treated and generates a component that moves the main body 2 in the up and down direction. In particular, when the massage mechanism 5 operates to sandwich the shoulders of the user P from the front and back between the kneading treatment elements T1 and the gripping treatment elements T2 as described above, that is, when the distance between the kneading treatment elements T1 and the gripping treatment elements T2 is narrowed, a force with a directional component that lifts the main body 2 from the shoulders of the user P is generated.

[0032] As shown in Figs. 5 to 7, the wearing unit 4 secures the main body 2 to the user P with the shoulder strap 3 hung on the shoulder of the user P and the main body 2 (treatment unit 2S) in contact with the area to be treated. More specifically, as shown in Figs. 1 to 4, the wearing unit 4 has a belt member 6. The belt member 6 has a waist belt 7, a tightening belt 8, and a tightening adjustment tool 9.

[0033] 6 and 7, the belt member 6 is a member that extends from the main body 2 toward the back of the user P, passes under the armpits of the user P, and reaches the shoulder strap part 3, and holds and fixes the body part of the massage machine 1, including the main body 2 and the shoulder strap part 3, on the shoulder of the user P. In this way, by passing under the armpits of the user P, the belt member 6 prevents the main body 2 from floating up when the massage mechanism 5 is driven.

[0034] As shown in FIGS. 3 and 6, the waist belt 7 is a band formed in an inverted Y-shape or an inverted T-shape when viewed from the rear, and includes a vertical band portion 11 and a horizontal band portion 12. The waist belt 7 includes an outer cover made of the same material as the outer cover of the main body portion 2, and a bendable plate-shaped core material. Therefore, the waist belt 7 has shape retention, but can be bent within a predetermined range. In other words, the waist belt 7 is bendable. As a result, a part of the waist belt 7 (for example, the horizontal band portion 12) is positioned along the contours of the user P's back when the massage machine 1 is worn on the user P (see FIGS. 6 and 7).

[0035] More specifically, as shown in Fig. 6, in this embodiment, the waist belt 7 has the vertical belt portion 11 arranged along the space between the left and right shoulder blades of the user P, and the horizontal belt portion 12 arranged along the lower parts of the left and right shoulder blades of the user P so as to support the left and right shoulder blades from below. 1 does not easily fall off from the user P even if the user P moves a little.

[0036] The vertical belt portion 11 extends rearward and downward from the center between the left and right sides of the main body portion 2. In this embodiment, the vertical belt portion 11 extends rearward and downward from the upper portion of the main body portion 2 (more specifically, from the top of the main body portion 2 when the massager 1 is properly worn on the user P). Therefore, by pulling the belt member 6 downward, a downward force is applied to the vertical belt portion 11, and as a result, the main body portion 2 is pressed forward and downward (in the extending direction of the shoulder strap portion 3 in this embodiment) by the vertical belt portion 11. This allows the treatment portion 2S (particularly the gripping treatment element T2) of the main body portion 2 to be more appropriately pressed against the shoulder (treatment portion) of the user P.

[0037] The horizontal belt portion 12 is integrally formed with the lower end of the vertical belt portion 11. The horizontal belt portion 12 extends in the left-right direction from the lower end of the vertical belt portion 11. In other words, the vertical belt portion 11 is connected to the center between the left and right of the horizontal belt portion 12. In this way, the waist belt 7 extends downward and rearward from the main body portion 2 and further extends forward on the left and right sides.

[0038] As shown in Figures 1 to 4, the tightening belt 8 is a flexible band made of nylon or the like, and extends forward from the side end 12E of the horizontal belt 12 (waist belt 7) when the massage machine 1 is in the basic position worn by the user P. More specifically, the tightening belt 8 extends forward from the side end 12E of the horizontal belt 12 and is inserted into a tightening adjustment tool 9 provided on the shoulder strap 3. Furthermore, the tightening belt 8 has its extending direction changed from forward to downward by the tightening adjustment tool 9, and extends downward from the shoulder strap 3.

[0039] Therefore, when the end of the tightening belt 8 is pulled downward in the extension direction (vertically downward of the main body 2, in the extension direction of the shoulder strap 3, or below the user P), the side end 12E of the horizontal band 12 is pulled toward the shoulder strap 3. As a result, the belt member 6 is attached more tightly (in a securely fastened state) around the waist of the user P. This allows the main body 2 to be fixed to the user P more stably.

[0040] As shown in FIGS. 1 to 4, the tightening belt 8 has a handle 13. The handle 13 is provided at the tip of the tightening belt 8. In this embodiment, the handle 13 is a substantially annular ring. When the user P wears the massage machine 1 as described above, the user P grasps the handle 13 with his or her hand and pulls the tightening belt 8. As such, the handle 13 is formed in an annular shape, so the user can easily place his or her hand on it. Furthermore, since a large grip strength is not required to pull the tightening belt 8, even a user P with a weak grip strength can press the main body 2 (massage mechanism 5) firmly against the area to be treated. This makes it easy to use.

[0041] The shape of the handle portion 13 is not limited to a circular shape, as long as it can appropriately pull the tightening belt 8. For example, the handle portion 13 may be formed in a rectangular ring shape or a spherical shape. Alternatively, the handle portion 13 may be formed in a T-shape or a rod shape. Furthermore, in the above embodiment, the handle portion 13 is configured as a separate member from the tightening belt 8, but the handle portion 13 may be formed integrally with the tip of the tightening belt 8. For example, the tip of the tightening belt 8 may be formed in a loop shape, or a through hole may be formed in the tip.

[0042] The fastening adjuster 9 is provided at the tip 3E of the shoulder strap 3. More specifically, as shown in FIGS. 9 to 11, the shoulder strap 3 has a loop 14. The loop 14 is provided at the tip 3E of the shoulder strap 3. The fastening adjuster 9 is connected to and held by the loop 14.

[0043] The tightening adjustment tool 9 has a support end portion 21, a middle frame portion 22, a first belt insertion hole 23, a second belt insertion hole 24, and a direction change portion 25. The support end portion 21 is a cylindrical portion that is long in the left-right direction. It is formed in a shaft shape and is provided on the upper side of the fastening adjustment tool 9. The support end 21 is inserted into the loop portion 14 and is rotatably inserted and held by the loop portion 14. In other words, the fastening adjustment tool 9 is connected and supported to the shoulder strap portion 3 so as to be rotatable with the support end 21 as a fulcrum.

[0044] In this embodiment, the fastening adjustment tool 9 is in a tensioned state where movement in the extension direction of the fastening belt 8 is prevented by posing the tip end 26 downward (see FIG. 10), and in a relaxed state where movement in the extension direction of the fastening belt 8 is permitted by posing the tip end 26 pulled forward (see FIG. 11). In this way, the fastening adjustment tool 9 allows tension and relaxation of the fastening belt 8 in the extension direction.

[0045] The middle frame portion 22 is a substantially flat frame body and is disposed horizontally in the vertical middle of the tightening adjustment tool 9. As shown in FIGS. 3 and 5, the upper side portion (upper oblique side portion) E1 of the middle frame portion 22 extends obliquely between the left and right side edges around the first belt insertion hole 23. In this embodiment, the upper side portion E1 extends obliquely downward from the outer side in the left-right direction of the massage machine 1 toward the center. Therefore, the tightening belt 8 inserted from the rear into the first belt insertion hole 23 comes into contact with the upper side portion E1 of the middle frame portion 22, whereby the tightening belt 8 is twisted by a predetermined angle and bent downward so as to be abducted. As a result, the tightening belt 8 is held in a more firmly tensed state relative to the tightening adjustment tool 9 by pulling it downward.

[0046] 9 to 11, the first belt insertion hole 23 and the second belt insertion hole 24 are both through-holes having approximately the same width as the tightening belt 8. The first belt insertion hole 23 is defined between the support end portion 21 and the middle frame portion 22. The second belt insertion hole 24 is defined between the middle frame portion 22 and the tip portion 26.

[0047] A lower edge portion (lower horizontal edge portion) E2 of the periphery of the second belt insertion slot 24 extends horizontally between the left and right side edges of the periphery of the second belt insertion slot 24. The tightening belt 8 inserted into the second belt insertion slot 24 comes into contact with the lower edge portion E2 of the periphery of the second belt insertion slot 24, and is thereby bent downward.

[0048] 9, the tightening belt 8 extends from the rear side (back side) of the tightening adjustment tool 9 to the front side (front side) of the tightening adjustment tool 9 through the first belt insertion hole 23. At this time, the tightening belt 8 abuts against the upper side E1 of the middle frame part 22 and is bent, changing its extending direction from forward to downward. In other words, the upper side E1 of the middle frame part 22 serves as a direction changing part 25 that bends the tightening belt 8 and changes its extending direction downward.

[0049] Furthermore, the tightening belt 8 inserted through the first belt insertion hole 23 passes in front of the middle frame portion 22 and again extends from the front side (front side) of the tightening adjustment tool 9 to the rear side (back side) of the tightening adjustment tool 9 through the second belt insertion hole 24. At this time, the tightening belt 8 abuts against the lower side E2 of the periphery of the second belt insertion hole 24 and is bent, changing its extending direction from rearward to downward. In other words, the lower side E2 of the periphery of the second belt insertion hole 24 serves as a direction changing portion 25 that bends the tightening belt 8 and changes its extending direction downward.

[0050] As described above, the direction changer 25 includes the upper side E1 of the middle frame 22 and the lower side E2 of the periphery of the second belt insertion hole 24. In other words, the direction changer 25 has the upper side E1 as an upper oblique side extending in a direction that intersects obliquely with the extension direction of the tightening belt 8, and the lower side E2 as a lower horizontal side extending in a direction that intersects with the extension direction of the tightening belt 8 at a right angle.

[0051] As shown in FIGS. 9 to 11, the lower side (lower horizontal side) E2 of the periphery of the second belt insertion hole 24 has a non-slip portion 27. The non-slip portion 27 is a small tooth-like protrusion, and is attached to the lower side E2. The anti-slip portions 27 are hooked onto the band surface of the tightening belt 8 inserted through the second belt insertion holes 24, thereby preventing the tightening belt 8 from moving in the extension direction.

[0052] 10, when the tip 26 of the tightening adjuster 9 is oriented downward, the anti-slip portion 27 presses against and engages with the belt surface of the tightening belt 8. This prevents the tightening belt 8 from moving in the extension direction and puts it in a tensed state. In this state, if the handle portion 13 at the tip of the tightening belt 8 is pulled downward (toward the tip), the waist belt 7 (the side end 12E of the horizontal belt portion 12) is held in a state where it is pulled toward the shoulder part 3. In other words, by pulling the tightening belt 8 downward, the tightening adjuster 9 holds the belt member 6 tightly fastened around the waist of the user P.

[0053] 11, if the tip 26 of the tightening adjustment tool 9 is pulled forward, the anti-slip portion 27 separates from the belt surface of the tightening belt 8. As a result, the tightening belt 8 enters a relaxed state in which movement in the extension direction is permitted (a state in which the belt 8 can move freely in the extension direction), and the tightening state of the belt member 6 on the user P is released. This allows the user P to easily remove the massage machine 1.

[0054] <Modification> In the above embodiment, the fastening adjuster 9 is provided at the distal end 3E of the shoulder strap 3, but it may be provided at the intermediate portion 3D between the proximal end 3F and distal end 3E of the shoulder strap 3. More specifically, the loop portion 14 is provided at the intermediate portion 3D of the shoulder strap 3. The fastening adjuster 9 is connected to and held by the loop portion 14.

[0055] In this modified example, the upper side E1 of the middle frame portion 22 extends substantially horizontally between the left and right side edges around the periphery of the first belt insertion hole 23. In other words, the direction changer 25 has an upper side E1 as an upper horizontal side extending in a direction intersecting at a right angle with the extension direction of the tightening belt 8, and a lower side E2 as a lower horizontal side extending in a direction intersecting at a right angle with the extension direction of the tightening belt 8.

[0056] In this case, the tightening belt 8 extending forward from the side end 12E of the waist belt 7 (horizontal band 12) changes its extending direction upward as it heads toward the tightening adjuster 9 provided at the middle portion 3D of the shoulder strap 3, and is then inserted into the first belt insertion hole 23. At this time, the tightening belt 8 abuts against the upper side (upper horizontal side) E1 of the middle frame 22 and is bent, changing its extending direction from upward to forward.

[0057] Furthermore, the tightening belt 8 extending forward of the first belt insertion slot 23 passes in front of the middle frame portion 22 and is inserted into the second belt insertion slot 24 from the front. At this time, the tightening belt 8 abuts against the lower side portion (lower horizontal side portion) E2 of the periphery of the second belt insertion slot 24 and is bent, and its extending direction is changed from backward to downward. In this way, the extending direction of the tightening belt 8 is changed from upward to downward by the tightening adjustment tool 9.

[0058] As in the above embodiment, the anti-slip portion 27 is provided on the lower edge (lower horizontal edge) E2 of the periphery of the second belt insertion hole 24, and by catching on the belt surface portion of the tightening belt 8 extending downward from the second belt insertion hole 24, it prevents the tightening belt 8 from moving in the extension direction.

[0059] In the above embodiment, the massage machine 1 is configured to be attached and fixed to the user P by a waist belt 7 and a tightening belt 8, but as shown by the dotted line in Figures 5 and 7, the belt member 6 may also include a chest belt 60 in addition to the waist belt 7, tightening belt 8, and tightening adjustment device 9.

[0060] The chest belt 60 has a connecting belt 61 and a buckle 62. Similar to the tightening belt 8, the connecting belt 61 is a flexible band made of nylon or the like, and extends forward from each of the left and right side end portions 12E of the horizontal belt portion 12. Therefore, when the massage machine 1 is worn by the user P, the connecting belt 61 passes under the left and right armpits of the user P and reaches the chest side.

[0061] The buckle 62 is provided at the tip of the connecting belt 61. The buckle 62 is a fastener that can be freely separated and connected using a snap-fit ​​structure. In other words, the buckle 62 is a fastener that has a pair of male and female connecting halves (e.g., a claw piece and a claw receiving portion) and can connect the two connecting halves together using the elasticity of at least one of the connecting halves (e.g., the claw piece). Therefore, the tips of the left and right connecting belts 61 can be easily separated and connected together using the buckle 62.

[0062] In this way, the massage machine 1 of this embodiment can be fixed to the user P using the chest belt 60 in addition to the waist belt 7 and the tightening belt 8, so it can be more stably attached to the user P. This makes it more difficult for the massage machine 1 to fall off the user P, making it even easier to use.

[0063] In the above embodiment, the waist belt 7 is formed in an inverted Y-shape or an inverted T-shape when viewed from behind, but as long as the massage machine 1 can be stably attached to the user P, it may have a shape other than the above, such as being formed in an approximately H-shape when viewed from behind, or the vertical belt portion 11 being formed in an approximately V-shape when viewed from behind.

[0064] In the above embodiment, the waist belt 7 is connected to the main body 2 by sewing the upper end of the vertical belt portion 11 to the main body 2. However, it may be removably connected to the main body 2. Specifically, the upper end of the vertical belt portion 11 of the waist belt 7 is connected to the main body 2 by a connecting member such as a slide fastener or snap buttons. Preferably, the waist belt 7 is connected to the main body 2 by a slide fastener so that it does not easily come off when pulled downward. The handle portion 13 is formed by bending the end of the tightening belt 8 into a loop. Therefore, the tightening belt 8 can be removed from the tightening adjustment device 9 by pulling it in the extension direction opposite to the end. In this way, the waist belt 7 can be separated from the main body 2 and the shoulder strap portion 3 by releasing the engagement of the slide fastener and removing the end of the tightening belt 8 from the tightening adjustment device 9. By removing the waist belt 7 from the main body 2 and the shoulder strap portion 3, the user P can change their style of use to suit their preferences, improving versatility.

[0065] The belt member 6 may be provided with a pad member that is placed between the belt member 6 and the body of the user P. Preferably, the pad member has a soft cover body and a cushioning material (a shock-absorbing material) that is housed inside the cover body. In this case, the belt member 6 and the fastening belt 8 do not come into direct contact with the body of the user P, improving comfort.

[0066] As such, the massage machine 1 of this embodiment is a massage machine comprising a main body 2 equipped with a massage mechanism 5 that massages the treatment area including the shoulders of the user P, and a pair of shoulder straps 3 extending to the left and right of the main body 2, and is provided with an attachment part 4 that secures the main body 2 to the user P when the shoulder straps 3 are placed on the shoulders and the main body 2 is placed against the treatment area, and the attachment part 4 has a belt member 6 that is provided on the shoulder straps 3 and passes under the armpits of the user P to secure the main body 2 to the user P.

[0067] According to this massage machine 1, the main body 2 can be attached and fixed to the user P by the belt member 6 so that the user P can carry it on his / her back, and therefore the user P can massage the area to be treated in a hands-free state. In other words, the user P can use both hands freely even during the massage. This makes it possible to realize a massage machine 1 that is easy to use. Furthermore, in the massage machine 1 of this embodiment, the shoulder strap part 3 and the belt member 6 form a loop shape, and the user P places his / her arms in the loop and carries the main body part 2 on his / her back with the belt member 6, so there is no problem that the main body part 2 floats up from the treatment part 2S.

[0068] The belt member 6 includes a waist belt 7 that extends downward and rearward from the main body 2 and further extends forward on both sides, a tightening belt 8 that extends from the side end 12E of the waist belt 7 to the shoulder strap 3 and pulls the side end 12E toward the shoulder strap 3 in the extending direction, and a tightening adjustment device 9 that allows the tightening belt 8 to be tensioned and relaxed in the extending direction.

[0069] According to this massage machine 1, by pulling the tightening belt 8, the side end portion 12E of the waist belt 7 and the shoulder strap portion 3 are pulled toward each other, so that the main body portion 2 can be quickly and easily attached and fixed to the user P. Also, by loosening the tightening belt 8 with the tightening adjustment tool 9, the massage machine 1 can be easily removed from the user P. Therefore, usability is further improved.

[0070] Moreover, in this device, by pulling the side end portion 12E of the waist belt 7 and the shoulder strap portion 3 toward each other as described above, the main body portion 2 is pressed firmly against the area to be treated. In other words, the user P can simultaneously pull the fastening belt 8 to attach and fix the main body portion 2 to the user P and press the main body portion 2 against the area to be treated. This makes it possible to realize a massage machine 1 that is even easier to use.

[0071] Furthermore, with this device, the degree of pressure of the main body 2 against the area to be treated can be adjusted by pulling or loosening the tightening belt 8 as described above. In other words, the strength of the massage can be adjusted by changing the degree of tightening of the tightening belt 8. This further improves usability.

[0072] The tightening adjustment tool 9 has a direction change portion 25 that bends the tightening belt 8 to change the extending direction downward.

[0073] According to this massage machine 1, the pulling direction (extension direction) of the tightening belt 8 can be made to coincide with the direction in which the main body part 2 is pressed against the part to be treated, which further improves usability.

[0074] The tightening adjustment device 9 is provided at the tip 3E of the shoulder strap portion 3, and the direction change portion 25 has an upper oblique side portion E1 extending in a direction that intersects obliquely with the extension direction, and a lower horizontal side portion E2 extending in a direction that intersects at a right angle with the extension direction.

[0075] With this massage machine 1, when the tightening belt 8 extending below the tightening adjustment tool 9 is pulled in the extending direction, the side end 12E of the waist belt 7 is pulled in conjunction with the tightening belt 8 toward the tip 3E of the shoulder strap 3, and the tightening belt 8 can be held in a tight state at that position, resulting in better wearability. Therefore, usability is further improved.

[0076] The tightening adjustment device 9 is provided at the midpoint 3D between the base end 3F and the tip end 3E of the shoulder strap portion 3, and the direction change portion 25 has an upper horizontal edge portion E1 extending in a direction intersecting perpendicularly to the extension direction, and a lower horizontal edge portion E2 extending in a direction intersecting perpendicularly to the extension direction.

[0077] According to this massage machine 1, the tightening belt 8 extending below the tightening adjustment tool 9 is When the bag is pulled in the direction of the shoulder strap 3, the side end 12E of the waist belt 7 is pulled toward the middle part 3D of the shoulder strap 3, and the fastening belt 8 can be held in a tight state at that position, resulting in better wearability. This further improves usability.

[0078] The lower horizontal side E2 has a slip prevention portion 27 that can be caught on the fastening belt 8 to prevent the fastening belt from moving in the extension direction.

[0079] According to this massage machine 1, the movement of the tightening belt 8 in the extension direction is more reliably prevented by the anti-slip portion 27, so that better wearability can be obtained, and usability is further improved.

[0080] The waist belt 7 extends downward and rearward from the upper portion of the main body 2 .

[0081] According to this massage machine 1, the force generated when the side end portion 12E of the waist belt 7 is pulled toward the shoulder strap portion 3 is applied to the upper portion of the main body portion 2, so that the main body portion 2 can be more stably attached to the user P. This further improves usability.

[0082] The waist belt 7 has one vertical belt portion 11 extending rearward and downward from the center between the left and right sides of the main body portion 2.

[0083] According to this massage machine 1, the force generated when the side end portion 12E of the waist belt 7 is pulled toward the shoulder strap portion 3 is applied to the center between the left and right sides of the main body portion 2, so that the main body portion 2 can be more stably attached to the user P. This further improves usability.

[0084] The waist belt 7 is formed in an inverted Y-shape or an inverted T-shape when viewed from the rear.

[0085] According to this massage machine 1, the waist belt 7 can be placed around the shoulder blades of the user P, so the main body 2 can be more stably attached to the user P. This further improves usability.

[0086] The massage mechanism 5 is configured to generate a component that moves the main body part 2 in an up and down direction when driven, so that the main body part 2 is lifted up from the shoulder, and the belt member 6 passes under the armpit to prevent the main body part 2 from lifting up.

[0087] According to this massage machine 1, the main body 2 can be prevented from floating up during massage, so that the massage machine 1 can be made easier to use.
