You.

Handles 31 are provided on both left and right sides of the casing 28 for holding the massage device 1 with both hands and carrying the massage device 1 or pressing the massage device 1 against others while using it. Is formed.

As shown in FIGS. 1 to 4, the massage unit 4 is disposed in a front-rear direction and a substantially central portion in the left-right direction of a casing 28, and is fixed to a lower half 28 B via a base 17. ing.

A drive motor 33 capable of normal and reverse rotation is attached to the upper surface of the base 17 substantially rearward, and a gear case 34 is provided on a front end face of the drive motor 33. In the gear case 34, the axial center of the rotating shaft 5 is rotatably supported, and is disposed in the casing 28 in the left-right direction.

Specifically, a pair of left and right bearings 35, 35 is provided inside the gear case 34, and the rotating shaft 5 is passed through both bearings 35, 35. A worm wheel 36 is fixed between the paired rings 35, 35 of the rotating shaft 5, and a worm gear 37 fixed to the output shaft of the drive motor 33 is mounted on the worm wheel 36. They are congruent.

The rotation of the drive motor 33 is transmitted to the rotation shaft 5 via a worm gear 37 in a gear case 34, and the rotation shaft 5 is configured to rotate freely in the forward and reverse directions. Is provided with a pair of left and right rotating bodies 6, 6 which are provided so as not to rotate relative to each other.

As shown in FIG. 2, a substantially circular orbit 11 having an axis A inclined with respect to the rotation axis 5 is formed on the peripheral surface 12 of the rotating bodies 6 and 6. The bosses 10 of the massage members 3, 3 are slidably fitted so as to slide. More specifically, an inner race of a pairing 39 is fitted into the outer peripheral surface (peripheral surface) 12 of the pair of left and right rotating bodies 6 and 6 along the track 11. At the outer side in the left-right direction, a fixing member 14 for preventing and fixing the bearing 39 is provided.

The outer race of the bearing 39 is fitted on the inner peripheral side of the ring-shaped boss 10, and through this bearing 39, the massage members 3, 3 slide on the track 11. ing. The rotating bodies 6, 6 are fixed to the rotating shaft 5 so that the inclination directions of the orbits 11 of the left and right rotating bodies 6, 6 are opposite to each other. Further, the massage members 3, 3 extend radially outward from the outer peripheral surface 12 of the boss 10. The affected part pressing body 2, 2 extends obliquely upward toward the outside of the casing 28.

As shown in FIGS. 1 to 3, the affected-part pressing bodies 2 and 2 have a width in the longitudinal direction of the track 11, and preferably have a size of a human fist. In the cross section, it is formed to be thinner than the massaging members 3 and 3 so that it can be elastically deformed in the axial direction of the rotating shaft 5. The lower part of the affected part pressing body 2, 2 which rises upward from the boss 10 of the massage members 3, 3, is formed as a flexible arm section 60, and the flexible arm section 60 is relatively easily left and right. It is formed so that it can be elastically deformed. The affected part pressing body 2, 2 continuing upward from the flexible arm part 60 is a side plate part 61, and the affected part pressing body 2 bent outward from the outer peripheral edge of the side plate part 61 in the left-right direction. , 2 are peripheral plate portions 62.

Therefore, the massage part is formed by the side plate part 61 and the peripheral plate part 62, and the pine surge part is formed so that the front-rear width increases from the lower side to the upper side.

In addition, the opposing inner side is formed in a rounded elliptical shape so as to have a soft contact surface with the neck N, and a plurality of substantially hemispherical convex portions 40 are formed in the affected area to enhance the massage effect. It is scattered on the surface of the pressing bodies 2 and 2.

A ring-shaped holding member 42 is attached to the left and right outer surfaces of the boss 10 to prevent the bearing 39 from falling off and fixed. An engaging member mounting portion 44 for mounting 3 is formed in a body, and a rod-shaped engaging member 13 is fixed so as to protrude from the boss portion 10. A cylindrical body 41 is rotatably fitted to the distal end of the engaging member 13.

A rectangular plate-shaped backup member (support) 26 extends from the holding member 42 toward the outside in the left-right direction of the affected-part pressing bodies 2, 2. , 2 and the flexible arm 60 and the side plate 61, and are spaced apart from the affected part pressing bodies 2, 2. Knockup member 26 is formed of a synthetic resin, metal, or the like, and is formed so as to bend in the left-right direction when an external pressure exceeding a predetermined value is applied.

A back-up member is provided between the distal end side of the back-up member 26 and the affected-part pressing body 2. An elastic member 43 made of a material such as urethane, which is softer than the member 26, is sandwiched therebetween. This elastic member 43 is fixed to the tip of the backup member 26c. However, it may be fixed to the affected part pressing body 2. The outer peripheral surface of the elastic member 43 is in contact with the side plate 61 of the affected part pressing body 2.

The back-up member 26 and the elastic member 43 are provided to the affected part pressing bodies 2, 2 when a load is applied to the affected part pressing bodies 2, 2 and the affected part pressing bodies 2, 2 are deformed outward in the left-right direction. The resistor 65 provides resistance to the deformation, and the resistance 65 allows the kneading force of the affected-part pressing bodies 2 to be changed and adjusted. For example, the patient is placed on the affected part pressing parts 2, 2 such as a waist to perform a massage, and in this state, the affected part pressing bodies 2, 2 are moved close to each other in the left-right direction. As the affected part pressing bodies 2, 2 approach each other, The load for pushing the affected part pressing bodies 2 and 2 outward in the left and right direction increases, and as a result, the affected part pressing bodies 2 and 2 are gradually deformed outward in the left and right direction and the elastic members 43 are formed. Start to be compressed. Then, the affected part pressing bodies 2 and 2 are further moved to the left and right by the load, and the elastic member 43 reaches the compression limit or before that, the backup member 26 and the affected part pressing bodies 2 and 2 are moved to the left and right outside. It is designed to bend to the radius.

At this time, the rubbing force P of the affected part pressing body 2, 2 is as follows. That is, as shown in FIG. 9, in the stage T1 in which the affected part pressing bodies 2, 2 are gradually deformed outward in the left-right direction and the elastic member 43 is compressed, the repulsive force P of the affected part pressing bodies 2, 2 against the deformation is obtained. 1 (restoring force) acts on the affected part pressing bodies 2, 2, and the repulsive force P 2 due to the compression of the elastic member 4 3 acts, so that the rubbing force P of the affected part pressing bodies 2, 2 This is the sum of the repulsive force P1 and the repulsive force P2 of the elastic member 43. In this case, since the affected-part pressing bodies 2: 2 are brought close to each other, the amount of deformation of the affected-part pressing bodies 2, 2 in the left-right direction increases, and the kneading force P gradually increases.

In addition, at the stage T2 in which the affected-part pressing bodies 2, 2 gradually deform outward in the left-right direction, the elastic member 43 reaches the compression limit, and the backup member 26 deforms outward in the left-right direction. The repulsive force P 1 (restoring force) of the affected part pressing bodies 2, 2 against the deformation acts on the affected part pressing bodies 2, 2, and the repulsive force P 3 due to the deformation of the backup member 26 acts on the affected part pressing bodies 2, 2. The kneading force P is equivalent to the repulsive force P 1 of the affected part pressing body 2, 2. This is the sum of the repulsive force P 3 of the backup member 26 and the force. In this case, since the affected-part pressing bodies 2 are brought close to each other, the amount of deformation of the affected-part pressing bodies 2, 2 in the left-right direction increases, and the kneading force gradually increases. At this stage T2, since the backup member 26 is formed of a material harder than the elastic member 43, the rate of increase of the repulsive force P3 of the backup member 26 with respect to the deformation amount is equal to the elastic member 43. (For example, the rate of increase changes at the position L1 where the elastic member 43 has reached the compression limit.) In addition, the rubbing force P of the affected part pressing bodies 2, 2 becomes maximum at a position L2 at which the backup member 26 is not deformed outward in the left-right direction.

On the other hand, when the affected part pressing bodies 2 and 2 are moved away from each other in the left and right direction while the backup member 26 is deformed to the position L2 where the affected part pressing bodies 2 and 2 can be bent outward in the left and right direction together with the affected part pressing bodies 2 and 2. However, as the affected part pressing bodies 2, 2 move away from each other, the load for pushing the affected part pressing bodies 2, 2 outward in the left-right direction decreases, and as a result, the affected part pressing bodies 2, 2 move with the movement of the affected part pressing bodies 2, 2. Since the backup member 26 can be returned to the original state before bending, and the compressed elastic member 43 can be returned to the original state before compression, the above-described steps T l, At T2, the amount of deformation of the affected-part pressing bodies 2, 2 in the left-right direction decreases, and the kneading force P can be gradually reduced.

Therefore, as can be seen from the above, the kneading force changing means for changing and adjusting the kneading force of the affected part pressing bodies 2, 2 by giving resistance to the deformation to the affected part pressing bodies 2, 2 deformed outward in the left-right direction due to the load, as can be seen from this. The kneading force changing means makes it possible to change the kneading force in multiple stages, and to make at least two stages different in the rate of change in the kneading force with respect to the deformation amount. By doing so, it becomes possible to apply massages with different kneading forces simply by placing the waist on the affected-part pressing bodies 2 as described above.

Further, when a load is applied to push the affected part pressing bodies 2, 2 outward in the left-right direction, the elastic deformation of the elastic members 43 supports the outwardly deformed affected part pressing bodies 2, 2. Further, if the load cannot be supported only by the deformation of the elastic body 43, the backup member 26 will support the affected part pressing bodies 2, 2 while being elastically deformed.c. When performing a massage of the lumbar W etc. Even if it does, it becomes possible to prevent the destruction, deformation, etc. of the affected part pressing bodies 2, 2.

In FIG. 9, the X axis indicates the amount of deformation of the affected part pressing body 2, 2 and the resistor 45 (backup member 26, elastic member 43) in the left-right direction, and the Y axis indicates the affected part pressing body. 2, 2, and the strength of the repulsive force or kneading force of the resistor 45 (backup member 26, elastic member 43).

In the present embodiment, the massaging member 3 is assembled by molding the boss 10, the affected part pressing body 2, and the pressing member 42 individually and fixing them with fasteners such as screws. Further, the engaging member 13 is fixed to the engaging member mounting portion 44 later by a fastener such as a screw. However, these may be formed by integral molding, or the backup member 26 may be separately molded, and may be fixed by being sandwiched between the boss 10 and the pressing member 42.

On the base 17 side substantially below the engaging member 13, there are provided control members 15, 15 in which sliding grooves 16 for engaging with the engaging member 13 are formed. That is, the connecting shaft 19 serving as a connecting member is provided substantially parallel to the rotating shaft 5 in the left-right direction of the base 17 and is arranged so as to be movable in the front-rear direction. Control members 15 and 15 are provided at both left and right ends of the connecting shaft 19 so as to be rotatable around the axis.

At the approximate center of the control members 15 and 15 in a plan view, a sliding groove 16 into which the engaging member 13 is slidably fitted is formed so as to penetrate substantially vertically. The sliding groove 16 guides the massage members 3, 3 in the left-right direction and also in the front-back direction. The longitudinal direction of the sliding groove 16 is It is inclined.

In the case of this embodiment, as shown in FIG. 4, the left sliding groove 16 is formed obliquely to the right with respect to the rotating shaft 5, and the right sliding groove 16 is formed obliquely to the left. You. However, there is no problem even if the inclination is reversed.

The engaging member 13 is inserted and fitted into the sliding groove 16 from substantially above. A rotatable cylinder 41 is fitted into the engagement member 13, and the cylinder 41 is in contact with the sliding groove 16. You can slide smoothly.

As described above, the engaging member 13 provided substantially below the massaging members 3 and 3 is The control members 15, 15 are fitted into the inclined sliding grooves 16 of the sliding members 16, and can swing freely in the left and right components of the sliding grooves 16. When the massaging members 3 and 3 are fitted to 1, a swelling motion mechanism that converts the rotation of the rotating bodies 6 and 6 into swelling motions of the massaging members 3 and 3 while regulating the rotation of the massaging members 3 and 3. 7 will be configured. '

That is, when the boss 10 moves along the inclined trajectory 11, in plan view (FIG. 4), for example, the boss 10, whose co-rotation is restricted with respect to the right rotating body 6, As the rotating body 6 rotates, it swings so as to transit between three states, that is, an obliquely upward left shoulder, a substantially vertical direction, and an oblique upward right shoulder with respect to the rotation axis 5. The rotator 6 on the left side also tilts symmetrically. Therefore, the affected-body pressing bodies 2, 2 protruding from both bosses 10, 10 perform the same movement. When one end in the front-rear direction approaches each other, the other ends separate from each other, and the ends separate. At this time, the seesaw swings so that the other end approaches.

On the other hand, in a front view (FIG. 2), the boss 10 swings about the rotation shaft 5 as described above, and the outer peripheral surface 12 also moves in the axial direction. However, since the affected part pressing bodies 2 and 2 are regulated to slide in the left and right directions by the sliding grooves 16 provided on the opposite side of the rotating shaft 5, the rotating shaft 5 In the axial direction (left and right direction) of each other.

In other words, focusing on a part of the opposing affected-part pressing bodies 2 in front view, the part moves toward and away from each other (reciprocating movement from side to side and near and far).

By combining these two, that is, by the combination of the seesaw swinging in a plan view and the reciprocating movement of the left and right in the front view, the affected part pressing bodies 2 and 2 move in opposite directions while moving toward and away from each other in the left and right direction. I will do it.

In addition, the massaging members 3, 3 are fitted to the rotating bodies 6, 6, and the engaging members 13 are fitted into the inclined sliding grooves 16, so that they can swing in the front-rear direction components. An attitude control mechanism 8 that reciprocates the massaging members 3, 3 and the affected-part pressing bodies 2, 2 in a fixed range in the circumferential direction of the rotating shaft 5 is configured.

Further, the engaging member 13 is fitted into the sliding groove 16 of the control members 15 and 15 so as to be interlocked with each other, and the control members 15 and 15 are moved in the front-rear direction. The massaging members 3, 3 are displaced in the circumferential direction of the rotating shaft 5 via the engaging members 13, and the affected part is pushed. The position changing mechanism 9 that changes the angle (lift angle) formed by the pressure bodies 2 and 2 with respect to the rotation axis 5 and changes the height is configured.

The position changing mechanism 9 has a moving means 18 for moving the control members 15, 15 in the front-rear direction with respect to the base 17. The moving means 18 includes an operating knob 20 which is an operating body provided on one of the left and right sides of the lower half body 28B, a driving shaft 21 for driving the connecting shaft 19, and a driving shaft 2 1 has a gear portion 3 8 for transmitting the rotation of the operating knob 20 and a connecting member 23 for moving the connecting shaft 19 back and forth by the rotation of the driving shaft 21 c. An operation rotary shaft 24 extending into the casing 28 is provided, and the drive shaft 21 can be rotated via a gear portion 38 composed of a bevel gear. A screw portion 22 is formed in the longitudinal direction of the drive shaft 21 so that one end of the connection tool 23 is screwed and the other end is fixed to the connection shaft 19.

Therefore, by turning the operation knob 20, the drive shaft 21 is rotated via the gear portion 38, and the connecting tool 23 is moved in the front-rear direction, so that the connecting shaft 19, that is, the left / right control member 1 5, 15 move in the front-back direction.

As the control members 15 and 15 move in the front-back direction, the engagement members 13 fitted in the sliding grooves 16 also move back and forth, for example, the control members 15 and 15 move rearward. In this case, the engagement member 13 also rotates rearward in a plan view. Therefore, the affected part pressing bodies 2, 2 located on the substantially opposite side to the rotation axis of the engaging member 13 rotate forward around the rotation axis 5, and the lifting angle of the affected part pressing bodies 2, 2 is small. The height of the affected part pressing bodies 2 and 2 from the bottom surface of the casing 28 decreases.

When the control members 15, 15 are moved forward, the opposite is true, and the height of the affected part pressing bodies 2, 2 increases.

As shown in FIG. 3, when the massage members 3, 3 rotate around the rotation axis 5, the protruding direction of the engagement member 13 with respect to the rotation axis 5 also changes. However, since the control members 15 and 15 are rotatable around the connecting shaft 19, the control members 15 and 15 can cope with a change in the projecting direction of the engaging member 13 and always engage the sliding groove 16 substantially vertically. The member 13 is fitted so that smooth sliding can be performed.

Next, the massage method by the massage device 1 according to the present embodiment is shown in FIGS. It will be described based on.

In the massaging apparatus 1 of the present embodiment, when the drive motor 33 is turned on and rotated, the rotating shaft 5 rotates via the worm wheel 36 and the rotating bodies 6 and 6 rotate. However, since the engaging member 13 is fitted in the sliding groove 16 of the control member 15, 15, the massaging members 3, 3 are restricted from co-rotating and move along the inclined track 11. Will be activated.

When the massaging members 3, 3 move along the inclined trajectory 11, the pair of left and right affected part pressing bodies 2, 2 are separated from each other when one end in the front-rear direction approaches each other, and the other end is separated from each other. When moving away from each other, opposing swelling operation is performed so that the other end is close. Further, the massage members 3 and 3 make a swinging movement so as to move in the front-back direction by the posture control mechanism 8. That is, the engaging members 13 are guided in the front and rear directions by the sliding grooves 16, so that the massage members 3 and 3 and the affected-body pressing bodies 2 and 2 move back and forth with a certain width around the axis. I will do it.

As a result, in addition to the opposing swelling motion described above, the affected-part pressing bodies 2 and 2 make a large swinging motion in the front-rear direction, and perform a kneading up or down motion.For example, before and after the massage device 1 When the direction is made to correspond to the vertical direction of the human body H, when the affected part pressing body 2, 2 moves largely rearward, a kneading motion is performed, and when the affected body 2 moves largely forward, a kneading motion is performed.

FIG. 5 shows a state in which the neck portion N is placed so as to be sandwiched between the affected-part pressing bodies 2 and 2 to perform massage. As shown in this figure, when massaging the neck N of a human body H lying on his back, the lifting angle of the affected body pressing body 2, 2 is reduced, and the height is reduced. Massage can be performed without applying.

Also, when massaging the waist W of the human body H sitting in the chair 46, the lifting angle of the affected body pressing body 2, 2 should be increased, the height should be increased, and the backrest of the chair 46 should be increased. By placing the case 28 against the 47 and applying the waist W to the affected body pressing bodies 2 and 2, the surge can be performed. At this time, since the affected-part pressing bodies 2 and 2 are located at a position where the lifting angle is large and high, the affected-part pressing bodies 2 and 2 hit the waist W naturally without taking a posture such as sitting deeply on the chair 46. Be in touch. As described above, the height of the affected part pressing bodies 2 and 2 is changed, that is, the affected part pressing bodies 2 and 2 are changed. The lifting angle can be changed by using the position changing mechanism 9 as shown in FIG. 3, and when the control members 15 and 15 are moved forward, as shown by a two-dot chain line, The joint member 13 also moves forward, and the massage members 3, 3 rotate backward around the rotation axis, so that the lifting angle of the affected-part pressing bodies 2, 2 increases. That is, the height of the affected-body pressing body 2 is increased.

Conversely, when the control members 15, 15 are moved backward, the height of the affected-part pressing bodies 2, 2 decreases.

According to the massage device 1 of the present embodiment, it is regulated by the control members 15 and 15 that the massage members 3 and 3 are co-rotated (co-rotated) with the rotating bodies 6 and 6, whereby the massage members 3 and 3 are regulated. Since the affected part pressing bodies 2 and 2 are held at predetermined positions in the circumferential direction, when the affected part is pinched or abutted between the affected part pressing bodies 2 and 2, the affected part pressing bodies 2 and 2 do not escape in the circumferential direction, and the affected part pressing bodies 2 and 2 Can be easily aligned with the affected part.

Further, for example, when the neck N is placed so as to be sandwiched between the affected-part pressing bodies 2 and 2 and the affected-part pressing bodies 2 and 2 are moved toward and away from each other in the left-right direction and rubbed, when the affected-part pressing bodies 2 and 2 are brought close to each other, The amount of deformation of the affected part pressing body 2, 2 in the left-right direction increases in the increasing direction, and the kneading force (pressing force) of the affected part pressing body against the neck N gradually increases due to the kneading force changing means. When the pushers 2 are separated from each other, the amount of deformation of the pushers 2, 2 in the left-right direction becomes a decreasing direction, and the rubbing force (pressing force) of the pusher against the neck N gradually decreases. Therefore, the kneading force of the left and right affected part pressing portions 2 is changed, and a surge with different kneading force can be applied.

FIG. 7 shows a second embodiment of the surge device 1 according to the present invention. The present embodiment has substantially the same configuration as the first embodiment, except that the sliding grooves 16 provided in the control members 15 and 15 are not inclined grooves.

That is, the longitudinal direction of the sliding groove 16 is formed substantially parallel to the rotating shaft 5. Therefore, the massage members 3, 3 are not guided by the front-back direction component, and the affected-part pressing bodies 2, 2 perform only opposing swelling motion.

Further, the control members 15 and 15 can be moved in the front-rear direction by substantially the same moving means 18 as in the first embodiment, and the affected part pressing bodies 2 and 2 change their protruding directions around the axis. It is possible to change the lifting angle of the affected part pressing body 2, 2 It is.

With this configuration, the moving means 18 is operated in accordance with the opposing swelling motion, and the affected part pressing bodies 2 and 2 are moved in the front-rear direction, thereby rubbing up or down the affected part pressing bodies 2 and 2. Can also be performed.

FIG. 8 shows a third embodiment of the massage device 1 according to the present invention. This embodiment has substantially the same configuration as that of the first embodiment, except that the control members 15 and 15 are fixed to the base 17 side without moving in the front-rear direction. It is different.

Thereby, although the position changing mechanism 9 is omitted in a simple configuration, the affected-part pressing bodies 2 and 2 can be swelled up and down and swayed back and forth to perform the kneading up and down movements.

10 to 12 show a massage device according to a fourth embodiment of the present invention. The backup member 26 (support) is made of a synthetic resin or the like as in the first embodiment, and bends in the left-right direction when an external pressure exceeding a predetermined level is applied. The backup member 26 is disposed apart from the affected part pressing bodies 2, 2 in the left-right direction, and an elastic member 43 is fixed to the distal end side of the backup member 26.

The elastic member 43 is disposed apart from the affected part pressing bodies 2, 2 in the left-right direction. When the affected part pressing bodies 2, 2 are not deformed outward in the left-right direction, the affected part pressing bodies 2, 2 are separated from each other. When the affected part pressing bodies 2 and 2 are deformed outward in the left and right direction without contact, the outer peripheral surfaces of the affected part pressing bodies 2 and 2 (side plate portions 61 of the affected part pressing bodies 2 and 2) are brought into contact. It is composed of The compression starting point of the elastic member 43 is different from that of the first embodiment.

According to the above configuration, for example, when the patient is placed on the affected part pressing portions 2 and 2 to perform a massage, and the affected portion pressing bodies 2 and 2 are moved close to each other in the left and right direction or separated from each other in this state, The rubbing force P of the affected part pressing body 2, 2 is as follows. That is, as shown in FIG. 12, in the stage T3 until the affected part pressing bodies 2, 2 are deformed outward in the left-right direction and come into contact with the elastic member 43, the repulsive force P of the affected part pressing bodies 2, 2 against the deformation is obtained. Since only 1 (restoring force) acts on the affected-part pressing bodies 2 and 2, the rubbing force P of the affected-part pressing bodies 2 and 2 is the same as the repulsive force P1 of the affected-part pressing bodies 2 and 2. The affected body pressing body 2 At the stage T4 in which the elastic members 43 are compressed by the contact between the affected part pressing bodies 2 and 2, the rubbing force P of the affected part pressing bodies 2 and 2 is reduced to the repulsive force P 1 of the affected part pressing bodies 2 and 2. This is the sum of the repulsive force P2 of the elastic members 43.

Further, at the stage T5 in which the affected part pressing bodies 2, 2 gradually deform outward in the left-right direction, the elastic member 43 becomes the compression limit, and the backup member 26 deforms outward in the left-right direction with the load. The rubbing force P of the affected part pressing bodies 2 and 2 is the sum of the repulsive force P1 of the affected part pressing bodies 2 and 2 and the repulsive force P3 of the backup member 26.

Therefore, as can be seen from this, it is possible to change the kneading force of the affected part pressing body 2 and 2 in multiple stages, and at least three stages in which the rate of increase and decrease of the kneading force with respect to the change amount are different, for example, It is possible to apply massage with different kneading force simply by placing the waist on the affected part pressing body 2,2.

Further, since the elastic member 43 and the affected part pressing bodies 2 are separated from each other, the front and rear ends of the affected part pressing bodies 2 can be freely deformed in the left-right direction. That is, when the affected part pressing bodies 2 and 2 are separated from the elastic member 43, for example, the front ends of the affected part pressing bodies 2 and 2 are deformed inward in the left and right direction, and the rear ends of the affected part pressing bodies 2 and 2 are deformed. The affected part pressing body 2 can be twisted in the left-right direction, for example, to deform the part outward in the left-right direction. Therefore, for example, even in a part having a different width and shape, such as a waist and a neck, the affected part can be fitted (fitted) to the affected part pressing bodies 2 corresponding to the shape of the affected part.

FIGS. 13 to 14 show a massage device according to a fifth embodiment of the present invention.

As shown in FIG. 14, the affected-part pressing bodies 2, 2 are formed such that the massage parts are bifurcated in the front-rear direction. In other words, the side plate 61 and the peripheral plate 62 of the affected part pressing bodies 2 and 2 have a shape in which the front and rear center portions are depressed downward, and the front and rear both sides have a circular shape protruding upward. I have.

The back-up member 26 is formed in a rectangular plate shape as in the first embodiment, and its front-rear width is slightly smaller than the front-rear width of the flexible arm 60 of the affected part pressing bodies 2, 2. Has become. An elastic member 43 is externally fitted to the distal end of the backup member 26. The shape of the elastic member 43 when viewed from the side is the shape of the pressing body 2, 2 when viewed from the side. The shape is almost the same as the shape.

That is, the elastic member 43 has a shape that is bifurcated in the front-rear direction and protrudes upward from the fitting portion 70 fitted with the backup member 26, and projects upward. It has substantially the same shape.

Therefore, when the front and rear ends 71F, 71R of the affected part pressing bodies 2, 2 are deformed outward in the left-right direction, the front and rear ends 71 of the affected part pressing bodies 2, 2 are formed by the front and rear protruding parts 72F, 72R of the elastic member 43. F, 71R can be supported. For example, the affected part is

Even when only the front end 7 IF, which is a part of the affected part pressing bodies 2 and 2, is deformed outward in the left and right direction when placed on the affected part 2, the affected part pressing bodies 2 and 2 are The front end 71F can be supported, so that even if only a part of the affected part pressing body 2, 2 is deformed in the left and right direction, massage can be performed while changing the kneading force. It becomes possible.

In the above description, the shape of the elastic member 43 in a side view is substantially the same as the shape of the affected part pressing body 2, 2 in a side view, but the shape of the knock-up member 26 in a side view is changed to the affected part pressing body 2. , 2 may be substantially the same as the shape in side view. Also, as shown in FIG. 15, only the backup member 26 is provided so as to be opposed to the side plate 61 of the affected part pressing bodies 2 and 2 and to be separated from the affected part pressing bodies 2 and 2 so that the affected part pressing bodies 2 and 2 are provided. May be changed.

Note that the present invention is not limited to the above embodiment.

For example, the surge unit 4 may be built into the back of a massaging chair so that a wide area from the shoulder to the waist can be massaged.

The moving means 18 is provided with a connecting member 19 slidably in the front-rear direction with respect to the base 17, extends the connecting member 19 to the outside of the casing 28, and slides the both ends of the connecting member 19 back and forth by hand. May be performed.

Further, the engaging member 13 is rod-shaped, and the control members 15 and 15 are formed with the sliding grooves 16 into which the engaging members 13 are fitted. That is, the sliding groove 16 is formed in the peripheral surface 12 of the boss portion 10, and the engaging member 13 may protrude from the control members 15 and 15, and the engaging member 13 is provided directly on the base 17. The control members 15 and 15 may be used. Further, the sliding groove 16 does not need to penetrate the control members 15, 15, and may be a groove having a concave cross section. There is no problem even if the rolling members are formed in the recesses and the rolling balls are accommodated in the respective concave portions, and the massage members 3 and 3 slide on the track 11 via the rolling balls.

[Industrial applicability]

The present invention is useful as a massage machine, particularly as a stationary massage machine.
