[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vibration type massaging device having a vibrator that is pressed against an affected area by the spring force of a coil spring.

[0002]

[Prior art]

 An eccentric weight is rotatably housed inside the vibrator in the vibration type massaging device for shoulders and back, and this eccentric weight and the output shaft of the motor are connected via the first coil spring. It is known that a second coil spring penetrates the inside of the spring in an axial direction to support the oscillator in a cantilever manner, and the motor is built in a rod-shaped grip. This massaging device is a hand-held type and is used by pressing the vibrator against the affected area while gripping the grip.

[0003]

[Problems to be solved by the device]

 By the way, the present inventor, instead of the hand-held type, built the vibration type massage machine having the above-mentioned configuration in a main body case placed on a floor or the like, and projected a part of the vibrator from an opening of the case, We proposed a massaging device that can massage the affected area by pressing the affected area such as the sole of the foot against this protruding portion.

In this massaging device, when the vibrator is strongly pressed against the affected area to obtain a strong massage, it is necessary to increase the spring force of the second coil spring. However, as a result of trial production, it was found that the vibration of the main body case was large, even though the vibration type massaging device was attached to the main body case with a vibration-proof structure.

That is, since the pressing force of the vibrator against the affected area depends only on the elastic deformation of the second coil spring, in order to obtain a strong massage effect by the vibrator, the spring force of the second coil spring is increased. Must. When the wire diameter of the second coil spring is reduced to reduce the spring force, the second coil spring is easily deformed when the vibrator is pushed by the affected area, and the second coil spring is large against the affected area. The oscillator cannot be pressed with a reaction force.

However, when the spring force of the second coil spring is strong (the rigidity of the spring is high), the amplitude of the vibrator is suppressed to a corresponding small value and the rotation of the eccentric weight that is rotated inside the vibrator is increased. The vibration energy generated by (the higher the rotation speed of the motor, the larger the unbalanced amount of the eccentric weight, the larger the vibration energy and the larger the amplitude of the vibrator). It is easily transmitted to the motor side via the coil spring. Therefore, the main body case is likely to be vibrated greatly via the vibrator.

An object of the present invention is to obtain a massaging device capable of strongly massaging a diseased part while suppressing vibration of a main body case having a built-in vibration massaging device.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the massaging device of the present invention is provided with a main body case having a through hole formed in a case wall which is a front surface in use, and a head protruding through the through hole to the outside of the main body case. A vibrator that vibrates due to the rotation of an eccentric weight built into the head frame, a motor that is connected to the eccentric weight via a first coil spring and that rotates the eccentric weight, and a cantilevered support of the vibrator when used. A vibratory massaging device having a second coil spring that biases the vibrator toward the affected part when the vibrator is pressed by the affected part, the vibrator and the body case being built in the main body case. And a biasing means that is sandwiched between and for biasing the vibrator toward the affected area during use.

In order to be able to massage the affected area with an appropriate force according to the affected area, the urging means includes an urging portion in contact with the vibrator and the urging portion connected to the urging portion. And an adjusting portion for changing the magnitude of the reaction force of the urging portion with respect to the portion.

[0010]

[Action]

 In the structure of the massaging device of the present invention according to claim 1, the motor of the vibration type massaging device rotates the eccentric weight in the head frame of the vibrator through the first coil spring, and the eccentric weight is accompanied by the rotation. The whole vibrator is vibrated according to the balance amount. The second coil spring of the massaging device elastically deforms when the head of the head frame protruding from the opening of the main body case is pressed by the affected part such as the sole of the user's foot, and presses the entire vibrator toward the affected part. . The biasing means sandwiched between the vibrator and the main body case pushes the entire vibrator toward the affected area by elastically deforming the vibrator when the vibrator is pressed by the affected area. Therefore, when in use, the vibrating element is strongly pressed against the affected area by the spring force of the second coil spring and the urging force of the urging means so that the affected area can be vibrated and the affected area can be strongly massaged. Accordingly, the spring force of the second coil spring can be reduced. Further, in the massaging device according to claim 2, the adjusting portion of the urging means has a reaction force of the urging portion in contact with the vibrator, that is, a force of the urging means pressing the vibrator toward the affected area during use. The size is adjusted, and by the adjustment, the pressing force of the vibrator to the affected area can be adjusted to the strength according to the affected area.

As shown in FIG. 5, the recessed portion 7 is a portion that is opposed to each other on the arcuate peripheral surfaces of one end portion of both massage portions 5 and 6, that is, the opposed surfaces 5 a and 6 a that are curved surfaces, and is connected to these. It is formed by the one end surface 4d of the remote control housing recess 4 and has a structure in which the distance between the facing surfaces 5a and 6a is gradually narrowed toward the back (in other words, as it goes to the remote control housing recess 4). . Reference numeral 8 in FIGS. 3 and 5 is a recess formed on the other end side of the remote control housing recess 4. These recesses 7 and 8 reduce the amount of material used to form the main body case 1 and give the main body case 1 an appearance suitable for being mainly used as a foot massager. You can omit it.

The case wall 3 a of the case member 3 forming one surface of the main body case 1 has a pair of through holes 11 a and 11 b located in the first and second massaging portions 5 and 6 (see FIGS. 1, 2 and 5 references). As shown in FIG. 5, these through holes 11a and 11b are formed near both sides of the rear end of the recess 7 (that is, one end surface 4d of the remote control housing recess 4).

The through holes 11 a and 11 b are individually covered and hidden by a cover 12. As shown in FIGS. 1 and 2, the peripheral edge of the cover 12 is fitted into an annular mounting groove 13 provided in the case wall 3a of the case member 3 so as to separately surround the through holes 11a and 11b. The ring-shaped cover mounting frame 14 fitted in the groove 13 is screwed into the mounting groove 13 so that it is sandwiched between them. The cover 12 is a sheet obtained by adhering a reinforcing cloth to the back surface of a thin vinyl chloride resin layer having a thickness of about 0.9 mm, and is flexible to follow the vibration of the vibrator 55 described later. is doing.

As shown in FIG. 6, in the main body case 1, two vibrating massaging devices 21A, 21B respectively arranged in the first and second massage parts 5, 6 are arranged at a predetermined distance. It is set up. These agitators 21A and 21B are vibration-isolated and fixed apart from the inner surface of the case member 2 via a rubber 16 (see FIGS. 1 and 2). 2 and 6, 17 is a pressing washer for the anti-vibration rubber 16 and 18 is a screw, which are not in contact with the massaging devices 21A and 21B.

Further, the main body case 1 has a built-in control device 22 for performing necessary operation control on the massaging devices 21A and 21B. The control device 22 is formed by various circuit components 23 and a control printed wiring board 24 on which these components are mounted, and a motor control circuit for controlling a motor described later, a DC power supply circuit for driving this circuit, and a later-described It has a circuit such as a discrimination circuit of a control signal from a remote controller. The control device 22 is arranged between the two massaging devices 21A and 21B by utilizing the space between them.

In FIGS. 1 and 6, 34A and 34B are positioned at the ends of the first and second massage parts 5 and 6 on the side of the above-mentioned recessed portion 8 and are respectively mounted on the main body case 1 to provide printed wiring for display. A substrate, 25 is an indicator lamp such as an LED mounted on each of the printed wiring boards 34A and 34B, and 26 is a lamp cover made of black or gray sponge. The lamp cover 26 has the same number of holes penetrating in the thickness direction as the display lamps 25, and the respective display lamps 25 are separately housed in these holes, so that the printed wiring boards 34A and 34B and the inner surface of the case member 3 are covered. It is sandwiched between and to prevent chattering between them.

3 and 5, reference numeral 29 is a power cord connected to the control device 22 and projected outside the main body case 1, and 30 is also connected to the control device 22 and projected outside the main body case 1. It is a flexible spiral cord that can expand and contract. An elongated remote controller 31 is connected to the cord 30 of the spiral. The spiral cord 30 is a multi-core cord formed by covering a power line for transmitting electric power of a DC power source for driving an electronic circuit (not shown) built in the remote controller 31 and a signal line for transmitting a control signal.

As shown in FIG. 5, the remote controller 31 displays the operation unit 32 such as a plurality of push buttons for selecting the operation mode of the massaging device M, the power button 35, and the selected mode by a lighting operation. A display unit 33 for displaying and display characters are provided, and a control signal is sent to the control device 22 by operating the operation unit 32.

The thickness of the remote controller 31 is smaller than the depth of the remote controller housing recess 4, and is housed in the remote controller housing recess 4 in a detachable manner. The cord bush 36 provided at the connecting portion between the remote controller 31 and the spiral cord 30 is removably fitted into the groove 4a formed at one end of the remote controller housing recess 4, and the fitting allows the remote controller housing to be accommodated. The remote controller 31 is positioned with respect to the recess 4.

The two massagers 21A and 21B have the same configuration and are configured as shown in FIGS. 8 and 9. That is, reference numeral 41 in these drawings denotes a motor mounting frame which is fixed to the case member 2 at the three positions with the above-mentioned vibration-proof structure, to which a motor 42 with a commutator is mounted, and the motor 42 A spring bearing portion 43 located on the protruding side of the output shaft 42a is integrally provided. One end of a first coil spring 44 for transmitting a rotational force is fixed to the output shaft 42a, and an eccentric weight 45 having a center of gravity at a position eccentric to the axis of the spring 44 is fixed to the other end of the spring 44. It is fixed.

The motor 42 rotates the eccentric weight 45 at 1000 to 2000 rpm. This is because as the rotational speed of the motor 42 is increased, the vibrator 55, which will be described later, can increase the force of pushing the affected part, but when the rotational speed of the eccentric weight 45, in other words, the rotational speed of the vibrator 55 exceeds 2000 rpm, These are set in consideration because unpleasant numbness is given to the affected area, and the massage stimulus given to the affected area by the vibrator 55 is too small at a rotation speed of 1000 rpm or less. If the rotation speed is within this range, it is possible to give a comfortable and appropriate massage stimulus to the affected area.

The eccentric weight 45 is housed in the head frame 46 and is rotatably supported by the frame 46 via a bearing 47. The head frame 46 has a substantially cylindrical shape with both ends closed (see FIG. 7), and a spring bearing portion 48 facing the spring bearing portion 43 is provided on one end wall of the motor 42 side. The ends of the second coil spring 49 are fitted and fixed to the spring receiving portions 43 and 48, respectively. The second coil spring 49 is for biasing to obtain the pressing force of the vibrator to the affected area, and the head frame 46 is cantilevered by the spring receiving portion 43 via this spring 49. The first coil spring 44 is passed through the inside of the second coil spring 49 along the axial direction.

The head mounting portion 46 a formed on the head frame 46 is mounted with a heating element 51 having a heating element 50 for thermal treatment composed of a posistor, and the heating element 51 is covered to form an aluminum die. A metal head 52 made of cast or the like is attached. The head 52 is provided with a pair of large and small projections 53a and 53b having different diameters and a hemispherical tip.

The eccentric weight 45, the head frame 46, the bearing 47, the heating element 51, and the head 52 form a vibrator 55 serving as an acupressure element that is supported via the second coil spring 49. There is.

The vibrators 55 of the both massaging devices 21A and 21B are provided so that the large-diameter projections 53a of the head 52 are arranged close to each other and the small-diameter projections 53b of the head 52 are arranged far from each other, as shown in FIG. ing. The interval between the protrusions 53a is set to be substantially the same as the interval between the crucibles that are positioned so as to sandwich the spine of the crucible of the back on both sides of the spine of the user.

Due to the mutual arrangement of the heads 52, when the user sits on a chair and massages the arch of the foot, the protrusion 53b having a small diameter is mainly used to eliminate the contact between the both feet and the contact area to the arch. It is possible to prevent the arch of the foot from being overloaded due to the excessive load given to the chair despite the massage using the small protrusion 53b. Furthermore, when massaging the affected area such as the back or waist, a large-diameter protrusion 53a is mainly used to secure a large contact area to the affected area to prevent the affected area from becoming too painful due to the effect of weight. it can.

As shown in FIG. 1 and FIG. 2 as a representative, the heads 52 of the vibrators 55 included in the agitators 21A and 21B having the above-mentioned configurations are separately passed through the through holes 11a and 11b, respectively, and the main body It is projected to the outside of the case 1. The head 52 of these vibrators 55 is always in contact with the inner surface of the cover 12 by the spring force of the second coil spring 49, and pushes up the cover 12 to maintain the tension state.

As shown in FIG. 5, the longitudinal distance E between the pair of vibrators 55 and one end of the main body case 1 on the recess 7 side is equal to the distance E between the pair of vibrators 55 and the recess 8 of the main body case 1. It is smaller than the longitudinal distance F between the other end. The distance E is set to such a length that the pair of vibrators 55 correspond to the height of the waist of the sitting user when the main body case 1 is erected with the concave portion 7 facing downward. F is set to a length corresponding to the height of the portion between the scapula and hip on the back of the seated user when the main body case 1 is erected with the recess 8 facing downward. Has been.

As shown in FIG. 1, FIG. 2, FIG. 6 and FIG. 7, between the bottom wall of the case member 2 of the main body case 1 and the vibrator 55, an elastic member formed of, for example, sponge rubber is used. The bodies 61 are respectively sandwiched. The elastic body 61 is elastically deformed while being compressed when the vibrator 55 is pushed by the affected area, and the elastic force biases the vibrator 55 toward the affected area.

As shown in FIGS. 1 and 2, the elastic body 61 is in contact with the outer peripheral surface of the head frame 46 while avoiding the corner portion 46 b on the side opposite to the motor in the cylindrical portion of the head frame 46. 1 and 2, g is an escape space secured between the corner 46b and the corner side end surface 61a of the elastic body 61. By doing so, as described above, the vibration is generated along with the vibration of the vibrator 55. The corner portions 46b apply a local load to the elastic body 61 to prevent the elastic body 61 from being broken into pieces from that portion.

1, FIG. 2, FIG. 6 and FIG. 7, reference numeral 62 denotes a connecting plate which is laid across a pair of vibrators 55, and prevents twisting of both vibrators 55 caused by the second coil spring 49. It is provided in order to prevent and obtain the correct pressed state to these affected areas. Further, reference numeral 63 in FIG. 6 denotes a reflection type photo switch fixed to the inner surface of the case member 2, which is turned on when the reflected light from the connecting plate 62 is received, and the motor 42 of both the abraders 21A and 21B. Are started at the same time.

The massage device M having the above-mentioned configuration is mainly used as a foot massager. At this time, the user C sits on a chair as shown in FIG. 10 (A) and puts the arches of both feet on the pair of transducers 55 via the covers 12 separately. Then, as the vibrator 55 is pushed down by the weight of the foot, the connecting plate 62 intersects the optical path of the photo switch 63, so that the switch 63 receives the reflected light from the connecting plate 62 and is turned on. As a result, the motors 42 of the pair of massaging devices 21A and 21B are activated.

Therefore, since the output shaft 42a of the motor 42 rotates the eccentric weight 45 via the first coil spring 44, the entire vibrator 55 vibrates with this rotation, and this vibration causes the head to vibrate. 52 is transmitted to the arch through the cover 12 so that the soles of both feet can be massaged respectively.

When used as a foot massager in this way, the remote control storage recess 4 (whether or not the remote controller 31 is stored) between the pair of transducers 55 is seated on a chair. The user's C foot can be used as a guide when placing the foot of the user C on a fixed position, that is, on the pair of massage parts 5 and 6, respectively. It is useful. Even if the remote controller 31 is housed in the remote controller housing recess 4, since the thickness of the remote controller 31 is smaller than the depth of the remote controller housing recess 4, the remote controller 31 housed in the remote controller housing recess 4 is It does not get in the way when the foot is placed on the main body case 1 by being projected onto the remote control storage recess 4. Therefore, both feet can be easily set (placed) on the pair of vibrators 55, respectively.

Further, since the remote control housing recess 4 is located between the pair of vibrators 55, the vibrators 55 are arranged at positions further apart from each other. Therefore, by placing feet on both sides of the remote controller housing recess 4, it can be used. It is possible to place both legs of the person C (including the thigh, the shin and the foot) in a natural state with the legs slightly opened and to place the both feet on the vibrator 55 of the pair of massage units 5 and 6. Then, both legs of the user C sitting on the chair will not come into contact with each other, and a gap can be formed between the thighs of the user C.

Therefore, the operation unit 32 of the remote controller 31 housed in the remote control housing recess 4 can be operated from above without being obstructed by both feet through the gap between the thighs, and the display unit 33 of the remote controller 31 can be operated. Can be seen from above through the gap between the thighs without being disturbed by both feet. As described above, when massaging the sole as shown in FIG. 10A, the operation mode setting operation can be facilitated and the operation mode display can be easily seen.

Further, as shown in FIG. 10B, the calves of both feet are separately placed on the pair of transducers 55 while sitting on the floor, so that the calves of both feet are massaged respectively. it can.

Then, as shown in FIG. 10C, in a state of sitting on the chair, the massage device M is inserted between the back of the chair and the back so that the concave portion 7 faces upward, and the back is placed. By leaning against the back, the motor 42 of the pair of massaging devices 21A and 21B can be activated to massage the back with the pair of vibrators 55.

Similarly, by inserting the massaging device M between the backrest and the waist of the chair with the concave portion 7 thereof facing downward, and leaning against the backrest, the pair of vibrators 55 are respectively vibrated. You can massage the lower back.

When using FIG. 10 (C), the remote controller 31 is detached from the remote control accommodating concave portion 4 and placed in the hand of the user C. Therefore, if the operation mode is changed during this use, it can be handled by hand operation, and the massaging device M can be taken out from between the backrest of the chair and the upper body of the user C to operate the operation mode. There is no need to change the mode. Also, when using FIG. 10B, it is possible to operate with the remote controller 31 at hand.

The strength of the massage when the massage device M is used is given by the spring force of the second coil spring 49 and the elastic force of the elastic body 61. That is, as shown in FIG. 2 as a representative, when the transducer 55 is pushed down from the solid line position to the one-dot chain line position and further to the two-dot chain line position through the cover 12 in the affected area such as the sole of the foot, as a result, The second coil spring 49, which cantilever-supports the oscillator 55, is largely deflected to increase the spring force to urge the oscillator 55 toward the affected area and support the oscillator 55 from below. An elastic force (reaction force) generated by the elastic body 61 being compressed urges the vibrator 55 toward the affected part.

In this way, not only the spring force of the second coil spring 49 but also the elastic force of the elastic body 61 is taken into consideration, and the oscillator 55 can be strongly pressed against the affected area to give a strong massage.

Therefore, since the spring force of the second coil spring 49 can be reduced corresponding to the elastic force of the elastic body 61, the second coil spring 49 having a small wire diameter can be adopted. Therefore, the amplitude of the vibrator 55 due to the easiness of bending of the second coil spring 49 can be increased, and the massage operation can be improved. The energy absorbed by the deformation can be reduced from being transmitted to the motor 42 side through the second coil spring 49. In accordance therewith, the vibration that propagates from the vibration type abraders 21A and 21B to the case member 2 of the main body case 1 can be suppressed to a small level.

That is, in this massaging device M, the affected area can be strongly massaged while suppressing the vibration of the main body case 1. In addition to the fact that the main body case 1 can be used with reduced vibration in this way, the elastic body 61 is sponge rubber, so no sound is generated by its elastic deformation, and therefore quiet operation is possible. it can.

11 and 12 show a second embodiment of the present invention. In this embodiment, the same components as those in the first embodiment will be designated by the same reference numerals as those in the first embodiment, and the description thereof will be omitted. The configurations different from those of the first embodiment will be described below. To do.

In the second embodiment, one vibration type massaging device 21 is built in the main body case 1. The head 52 of the massaging device 21 uses one projection 53 provided on the upper surface of the central portion, and the case member 3 of the main body case 1 is provided with one through hole 11 accordingly. ing. Further, as shown in FIG. 11, the biasing means 71 includes a biasing portion 72 that contacts the vibrator 55 from the lower side, and a magnitude of the reaction force of the biasing portion 72 with respect to the affected part, which is connected to the biasing portion 72. And an adjusting unit 73 for changing the height.

As shown in FIG. 12, the biasing portion 72 is formed by incorporating an auxiliary elastic body 75 in an air bag 74 made of a flexible material such as vinyl chloride resin or rubber having excellent wear resistance. ing. The air bag 74 has a connecting pipe 74a (see FIG. 11). The auxiliary elastic body 75 is positioned so as not to move by such means as bonding only the lower surface thereof to the inner surface of the air bag 74. The biasing portion 72 is sandwiched between the bottom wall of the case member 2 and the vibrator 55.

The auxiliary elastic body 75 is formed of sponge rubber, and even when the air in the air bag 74 is exhausted to the atmospheric pressure, the vibrator 55 during operation as described in the first embodiment. It is adopted to provide a vibration between the case member 2 and the case member 2 and to apply a biasing force to the affected part to the vibrator 55.

The adjusting section 73 includes an air pump 76 and a solenoid valve 77. The solenoid valve 77 has first to third ports, and the air outlet of the air pump 76 is connected to the first port via the air supply tube 78. The connecting pipe 74a is connected to the second port, and the third port is open to the atmosphere. The solenoid valve 77 closes the third port when it is operated so that the first port and the second port communicate with each other, and keeps the second port closed during operation or closes the first port. The one that connects the 2nd port and the 3rd port is adopted.

The air pump 76 and the solenoid valve 77 are electrically connected to the control device 22 a incorporated in the main body case 1, and their operations are controlled via the control device 22 a and the control thereof is performed. The command is given by the remote controller 31a. The remote controller 31a is also provided with an operation section (not shown) for giving a command to change the magnitude of the biasing force of the biasing means 71 toward the vibrator 55 toward the affected area.

The configuration other than the points described above is the same as that of the first embodiment, including the portion not shown.

In the structure of the second embodiment, not only can the intended purpose of the present invention be achieved by the same operation as that of the first embodiment, but also by the affected part such as the sole of the foot, the back, the waist, or the affected part. Also, depending on the shape, the force that the projection 53 of the vibrator 55 pushes the affected part (massaging force) is different, so that the optimum massage intensity according to the affected part can be arbitrarily obtained.

That is, the force by which the protrusion 53 of the vibrator 55 pushes the affected part is due to the static load due to the total of the reaction force at the second coil spring 49 and the reaction force at the biasing means 71 and the centrifugal force of the eccentric weight 45. This is the total of the dynamic load, but since the reaction force of the second coil spring 49 and the dynamic load in a specific operation mode are constant, the reaction force is adjusted by the urging means 71. You can set the optimal massage strength.

The reaction force of the urging means 71 is adjusted as follows. First, the remote controller 31a is operated to operate the air pump 76 regardless of whether the massage device is stopped or in use. At this stage, since the solenoid valve 77 is in the operated state and the first and second ports thereof are in communication with each other, the air from the air pump 76 passes through the air supply tube 78 and passes through the solenoid valve 77. The air bag 74 is inflated by being supplied into the air bag 74 of the biasing means 71.

Then, when the air bag 74 is appropriately inflated, the operation of the air pump 76 is stopped, and at the same time, the solenoid valve 77 is operated to close the second port thereof. The operation of the electromagnetic valve 77 is interlocked with the stop operation of the air pump 76, and the operating state thereof is maintained. Therefore, the vibrator 55 is urged upward, that is, toward the affected area according to the internal pressure of the air bag 74.

In this state, when the remote controller 31a is operated to close the first port of the solenoid valve 77 and to switch the communication between the second and third ports, the inside of the air bag 74 is closed by the solenoid valve 77. The air in the air bag 74 can be evacuated because it is communicated with the atmosphere via the. Therefore, when the internal pressure of the air bladder 74 becomes too high, the internal pressure of the air bladder 74 can be lowered by the above operation, and the air bladder 74 can be finely adjusted to inflate at an appropriate pressure.

By increasing the internal pressure of the air bag 74 as described above, the magnitude of the reaction force of the biasing means 71 toward the affected area when the projection 53 is pressed by the affected area is changed to obtain the optimum value according to the affected area. Therefore, a more comfortable massage can be performed when the massage device according to the second embodiment is used.

FIG. 13 shows a third embodiment of the present invention. In this embodiment, the same components as those of the second embodiment will be designated by the same reference numerals as those of the second embodiment, and the description thereof will be omitted. The configurations different from those of the second embodiment will be described below. explain.

The third embodiment differs from the second embodiment in the configuration of the biasing means 81. That is, the urging means 81 includes an urging portion 82 that contacts the vibrator 55 from below and an adjustment that is connected to the urging portion 82 and that changes the magnitude of the reaction force of the urging portion 82 with respect to the affected area. Section 83.

The urging portion 82 has an elastic body 86 such as a coil spring sandwiched between a plate-shaped pressure body 84 having excellent wear resistance and a plate-shaped pressure base 85 arranged below the plate-shaped pressure body 84. These are housed and formed in a frame 87 whose upper and lower surfaces are open. The frame 87 regulates the pressing body 84 and the pressing base 85 so as not to rotate. The biasing portion 82 is mounted on the wall portion 2b having a U-shaped cross section provided on the bottom wall of the main body case 1, and the upper surface of the pressing body 84 is applied to the vibrator 55 by the biasing force of the elastic body 86. It is contacted from below.

The adjusting portion 83 is formed by attaching a knob 89 to a lower end portion of the operation shaft 88 which is rotatably attached to the central portion of the wall portion 2b. The operation shaft 88 is provided so as not to move up and down by a pair of upper and lower stop rings 90, and a screw portion formed on the upper portion thereof is screwed into the central portion of the pressure base 85. The operating shaft 88 can be manually rotated through the knob 89, and the knob 89 is housed in a recess 91 formed in the lower surface and formed by the wall portion 2b.

The configuration other than the points described above is the same as that of the second embodiment, including the portion not shown.

In the configuration of the third embodiment, by pinching the knob 89 in the recess 91 and rotating the operating shaft 88, the pressure base 85 screwed to the shaft 88 can be moved up and down. Due to this vertical movement, when the pressure base 85 approaches the pressure body 84, the initial strain of the elastic body 86 increases, and when the pressure base 85 moves away from the pressure body 84, The initial strain of the elastic body 86 becomes small.

By adjusting the initial strain of the elastic body 86 as described above, the magnitude of the reaction force toward the affected area by the urging means 81 when the protrusion 53 is pushed by the affected area is changed, and the optimum value according to the affected area is obtained. You can get a good massage strength. Therefore, when using the massage device according to the third embodiment, a more comfortable massage can be performed.

The present invention is not limited to the above embodiments. For example, a leaf spring or the like may be used for the elastic body 61 in place of sponge rubber in the first embodiment. Also, when the oscillators 55 form a pair, it does not matter if one and the other of the pair of oscillators 55 are plural, and the motor part of the massaging device is shared by the pair of oscillators 55. Alternatively, the through holes 11a and 11b of the main body case 1 may be one through hole. Further, when the vibrators 55 form a pair, the pair of vibrators 55 may be biased by the biasing means shown in the second and third embodiments. In such a case, If the reaction force of the biasing means is adjusted individually, the massage strength given to the affected part by the projection 53 of the vibrator 55 can be made different from each other according to the preference of the user according to the affected part. Alternatively, the cover 12 may be omitted and the vibrator 55 may be directly contacted with the affected area.

[Effect of device]

 As described above in detail, in the massaging device according to the first aspect of the present invention, when the vibrator is pushed by the affected part, the second coil spring of the massaging device is elastically deformed and the whole vibrator is pressed toward the affected part. At the same time as the attachment, the biasing means sandwiched between the vibrator and the main body case also presses the entire vibrator toward the affected area, so that the vibrator can be pressed strongly against the affected area and the affected area can be massaged strongly. Since the spring force of the second coil spring can be reduced according to the urging force of the urging means, the transmission of vibration from the vibrator side to the motor side is suppressed via the second coil spring, so that the vibration of the main body case is suppressed. Can be made smaller.

Further, in the massage device of the present invention according to claim 2, since the magnitude of the reaction force for pressing the vibrator toward the affected area can be adjusted by the biasing means, the pressing force of the vibrator against the affected area can be adjusted. You can massage the affected area comfortably by adjusting the size to the position and shape of the affected area.
