Hereinafter, embodiments will be described with reference to the drawings.
As shown in FIG. 1, the facial muscle training tool 21 of this embodiment is held by the user's lips, and the user swings the facial muscle training tool 21 up and down, so that the user's mouth and muscles In addition, facial muscles such as the buccal muscles, laughing muscles, large zygomatic muscles, and small zygomatic muscles connected to the muzzle muscles are trained.

  As shown in FIGS. 3, 4, and 8, the facial muscle training tool 21 includes a linear strip-shaped elastic plate 22 made of a steel plate spring. As shown in FIGS. 9 and 11, a core 27 made of a hard resin such as polypropylene is fixed to the central portion in the length direction of the elastic plate 22 by molding using the elastic plate 22 as an insert. The core 27 is formed with a protruding portion 272 that protrudes from one end edge of the elastic plate 22. A hollow mouthpiece 28 is detachably attached to the projecting portion 272 of the core 27, and a gripping portion 24 that is held by the lips is formed by the mouthpiece 28 in this attached state.

  As shown in FIGS. 3, 6 and 8, the entire elastic plate 22 and the portion of the core 27 excluding the protruding portion 272 are molded with a coating 23 made of a synthetic resin such as polyurethane. The coating 23 is made of a material softer than the core 27. A pair of through holes 222 are formed on both ends of the elastic plate 22. The inner through-hole 222 functions to allow the synthetic resin to enter during the molding of the coating 23 and strengthen the bond between the elastic plate 22 and the coating 23. As shown in FIGS. 5 and 6, the bush 26 is forcibly fitted in the outer through hole 222 and protrudes from both the front and back surfaces of the elastic plate 22. However, the bush 26 is formed at a height that is not exposed on the surface of the coating 23. Small holes 224 are formed through both ends of the elastic plate 22. The small holes 224 also function to allow the synthetic resin to enter and strengthen the bond between the elastic plate 22 and the coating 23.

  A pair of left and right arms 31 are formed by the elastic plate 22 and the covering 23 on both the left and right sides of the core 27. In the arm 31, a weight portion 25 is provided at the distal end portion of the covering 23.

  Then, as shown in FIG. 1, the gripping portion 24 is held by the lips and the entire facial muscle training tool 21 is swung up and down, so that the weight portion 25 is elastic and the elastic plate 22 is elastic. Both arms 31 vibrate up and down in resonance with the swing. Here, the resonance means that the arm 31 vibrates greatly when a vibration having a frequency within a predetermined range is applied to the holding portion 24. In particular, it is preferable that the end portion of the arm 31 bends to a position higher than the height of the holding portion 24. As a result, a load acts on the facial muscles of the user holding the holding part 24, and the facial muscles are trained.

  As shown in FIGS. 9 to 13, an uneven portion 271 for hooking and holding the mouthpiece 28 is formed on the outer peripheral surface of the core 27. The mouthpiece 28 is made of a soft synthetic resin such as polyurethane that is softer and less slippery than the core 27. On the inner peripheral surface of the mouthpiece 28, an uneven portion 281 that can be engaged with the uneven portion 271 of the core 27 is formed. On the upper and lower sides of the central portion of the outer peripheral surface of the mouthpiece 28, recessed portions 282 that are held by the lips are formed. As shown in FIG. 13, the outer peripheral surface of the mouthpiece 28 is formed in an elliptical shape having a major axis extending in the left-right direction in the recess 282. Therefore, the curvature at the two upper and lower positions of the recess 282 is smaller than the curvature at the two left and right positions, and is flat, so that it is easy to feel. A concave portion 283 is formed on the outer peripheral surface of the distal end portion of the mouthpiece 28. A spherical convex portion 284 is formed on the distal end surface of the mouthpiece 28.

  A pair of flanges 285 are formed on the front and back sides of the arm 31 at the base end of the mouthpiece 28. The flange 285 protrudes from the other part of the mouthpiece 28. As shown in FIG. 9, when the facial muscle training tool 21 is placed on an installation surface 100 such as an upper surface of a table or the like, the flange 285 is installed on the installation surface 100. In contact with the surface 100, the mouthpiece 28 faces obliquely upward. Therefore, it is possible to prevent the portion of the mouthpiece 28 that is gripped by the lips from coming into contact with the installation surface 100 and maintain cleanliness.

  A plurality of types of mouthpieces 28 having different external dimensions and the like are prepared, and the user selects an appropriate mouthpiece 28 according to the size and shape of the mouth and fits the outside of the core 27. Can do. The mouthpiece 28 is softer than the core 27 and has a hardness of 60 degrees in a durometer of type A in accordance with JIS (Japanese Industrial Standard) K6253, for example. The weight of the main body of the facial muscle training tool 21 excluding the weight 30, that is, the main body composed of the elastic plate 22, the covering 23, the core 27, and the mouthpiece 28 is about 50 to 500 grams (g). The weight 30 is about 3 to 120 g.

  As shown in FIGS. 5 and 14, holding holes 29 are formed at both end positions of the covering 23. Both weight portions 25 are constituted by weights 30 that are detachably attached to the holding holes 29. A plurality of types of weights 30 having different weights are prepared, and the weights 30 having an arbitrary weight are selected according to the level of training required by the user and are detachably attached to the holding holes 29.

The facial muscle training tool 21 of this embodiment is provided with a cover 51 that constitutes a facial muscle training tool set together with the facial muscle training tool 21.
As shown in FIGS. 2, 15, 16, and 18, the cover 51 is made of a synthetic resin such as transparent or translucent polypropylene, polyethylene, or polyamide resin, and a pair of halves are provided via a central integral hinge 52. Shaped cover pieces 53 and 54 are provided. One of the cover pieces 53 and 54 constitutes a main body, and the other constitutes a lid body. In this embodiment, the lower cover piece 53 in FIG. 15 is a main body, and the upper cover piece 54 is a lid body. Both cover pieces 53 and 54 are each formed in a concave shape, and an accommodation space 511 is formed between them. The gripping portion 24 of the facial muscle training tool 21 and the central portion of the covering 23 are accommodated in the accommodating space 511, and this portion is covered by the cover 51. One cover piece 53 has a latching claw 55 and the other cover piece 54 has a receiving portion 56 with which the latching claw 55 is engaged. When the cover pieces 53, 54 are closed, The cover 51 is held in the closed state by the engagement between the catch pawl 55 and the receiving portion 56.

  Concave portions 58 are formed on the side walls of the cover pieces 53 and 54. When the cover pieces 53 and 54 are closed, the concave portions 58 constitute an opening 59 for passing the arm 31 while avoiding interference with the arm 31, and the edge of the opening 59 and the outer peripheral surface of the arm 31. A gap 60 is formed between the two. It should be noted that the edge of the opening 59 is formed in a circular arc shape so that no edge is formed in the opening 59, the edge is formed thick so as to increase the contact area with the arm 31, or the edge is formed. It is possible to prevent the arm 31 from being scratched or marked by being thick and having an arcuate cross section.

Next, the usage method of the facial muscle training tool 21 comprised as mentioned above is demonstrated.
As shown in FIG. 2, when the facial muscle training tool 21 is not in use, a cover 51 is attached to the center of the facial muscle training tool 21 to cover the holding part 24. Therefore, it is possible to keep the gripping part 24 that is a part that can be gripped by the lips clean. Further, since the cover 51 is shaped substantially along the outer surface of the mouthpiece 28, the facial muscle training tool 21 with the cover 51 attached can be stored in a dedicated case, and the facial muscle training tool 21 can be carried or stored. It becomes.

  When the facial muscles are trained with the facial muscle training tool 21, the cover 51 is removed. A mouthpiece 28 having a required outer dimension is attached to the core 27 in advance according to the degree of training required by the user of the facial muscle training tool 21 and the weight necessary for the holding holes 29 of both weight portions 25. The weight 30 is attached. In this state, the face oscillates up and down with the dent 282 of the gripping part 24 held against the lips. In this way, both weight portions 25 are resonated up and down via the elastic plate 22 made of a leaf spring with the weight of the facial muscle training tool 21 acting on the lips, and the vibration is transmitted to the holding portion 24. Is done. As a result, a load is applied to the facial muscles through the lips, and the facial muscles are trained.

  In this case, the holding part 24 protrudes from the side edge of the arm 31 and is disposed at a position displaced outward from the side edge. For this reason, the facial muscle training tool 21 is held on the lips in a cantilever state, and the load on the lips increases. Therefore, the load due to resonance acts efficiently as a load on the facial muscles, and the facial muscles are effectively trained. At this time, since the recess 282 is formed in an oblong cross-sectional oval shape, the mouthpiece 28 can be held with the mouth open in a round shape. By holding the mouthpiece 28 with the mouth open, a load caused by resonance can be transmitted to the entire muzzle muscle. In addition, since the facial muscles such as laughing muscles are connected to the muzzle muscles, the laughing muscles and the like can be trained through the muzzle muscles, and efficient training is possible.

  Since the elastic plate 22 is molded with the synthetic resin coating 23 in the facial muscle training tool 21 of this embodiment, when the arm 31 is bent and resonates, other than the vertical vibration of the arm 31 to be obtained for training. It is possible to suppress movement, for example, torsion and fine vibration of the elastic plate 22. Therefore, it is possible to reduce the transmission of disturbing movements to the user's lips, and the facial muscle training tool 21 can be used comfortably. Instead of molding the entire elastic plate 22, a synthetic resin plate or sheet may be fixed to the front and back surfaces or one of the front and back surfaces by adhesion or the like.

  The mouthpiece 28 is not slippery and has a rubber property with an appropriate hardness. For this reason, it is easy to hold and the load caused by the vibration of the arm 31 can be transmitted to the lips. If the mouthpiece 28 is too hard, the mouthpiece 28 does not fit into the lips and is difficult to squeeze. On the other hand, if it is too soft, it is difficult to maintain the facial muscle training tool 21 in a stable state even if it is frightened, and the vibration of the arm 31 is absorbed and the load for training is reduced.

  When different users use the facial muscle training tool 21, the mouthpiece 28 on the core 27 is replaced with another mouthpiece 28 having a different external dimension, so that the mouth size and shape are different. Even a user can share one facial muscle training tool 21.

Furthermore, the weight 30 in the holding hole 29 of the weight portion 25 can be replaced with another weight 30 having a different weight according to the strength of the facial muscles or the degree of training.
After completion of the training, the mouthpiece 28 can be removed from the core 27 as necessary and cleaned, and the mouthpiece 28 after cleaning is attached to the core 27 again. Accordingly, the mouthpiece 28 can be kept clean and hygienic. Thereafter, a cover 51 is attached to the training tool 21 so as to cover the mouthpiece 28.

  As described above, by covering the mouthpiece 28 with the cover 51, the mouthpiece 28 can be kept clean when the training tool 21 is carried or stored. If the single mouthpiece 28 removed from the core 27 is accommodated in the cover 51, the mouthpiece 28 can be kept clean when the mouthpiece 28 is carried or stored.

Below, the manufacturing method of the facial muscle training tool 21 of this embodiment is demonstrated.
First, the core 27 is injection-molded using the elastic plate 22 as an insert at the center of the elastic plate 22 shown in FIG.

Next, the bush 26 is forcibly fitted into the pair of through holes 222 on both ends of the elastic plate 22. As a result, the bushes 26 project from both the front and back surfaces of the elastic plate 22.
Thereafter, as shown in FIG. 6, the elastic plate 22 is set in the molding die 101, and a synthetic resin that becomes the coating 23 is injected into the die 101. At this time, the injection pressure of the synthetic resin at the initial stage does not act uniformly on the elastic plate 22, and the same pressure temporarily acts on the elastic plate 22 unevenly. For this reason, there is a possibility that the elastic plate 22 is curved, and the molding surface of the cavity 102 of the mold 101 is scratched by the edge of the edge. However, in this embodiment, when the elastic plate 22 is curved, it is avoided that the bush 26 comes into contact with the molding surface of the cavity and the elastic plate 22 comes into contact.

  Accordingly, it is possible to prevent the molding surface of the cavity 102 from being damaged. In the state where the synthetic resin is completely filled in the cavity 102, the injection pressure acts uniformly on the entire elastic plate 22, so that the elastic plate 22 returns to its original shape so that the elastic plate 22 is in the cavity 102. It extends linearly at the center. Therefore, after the molding, the elastic plate 22 is molded at a fixed position in the molded coating 23.

  By the way, in the facial muscle training tool 21 of this embodiment, if the holding part 24 is rubbed up and down with a lip, the arms 31 on both sides will resonate while being bent. In this case, in the present embodiment, the length of the arm 31, the weight of the weight portion 25, and the elasticity so that the arm 31 resonates when the gripping portion 24 vibrates at a frequency of less than 6.50 hertz (Hz). The elastic coefficient and spring constant of the arm 31 including the plate 22 are set. For this reason, the user can resonate the arm 31 with a lip, and can perform effective training using the load. On the other hand, at a frequency exceeding 6.50 Hz, that is, when the gripping portion 24 is reciprocated in small increments, the arm 31 is not resonated, and therefore, it is similar to a state in which a rigid body that does not flex is vibrated, The load generated by the resonance of the arm 31 is not transmitted to the lips, and an effective training effect cannot be obtained.

  Further, in the facial muscle exercising tool 21 of the present embodiment, the downward bending rate of the arm 31 in a stationary state, that is, the downward bending amount a of the tip of the arm 31 with respect to the length b of the arm 31 shown in FIG. It is set to exceed 4.8 percent (%). For this reason, when the holding part 24 is vibrated up and down, the arm 31 is appropriately bent and vibrates. Therefore, the user can obtain an effective training effect. On the other hand, when the bending rate is 4.8% or less, that is, when the arm has high rigidity and is difficult to bend, it is difficult to resonate and it is difficult to obtain an effective training effect.

  Further, in the facial muscle training tool 21 of the present embodiment, the load applied to the holding portion 24 when resonance acts on the arm 31 is set to be less than 7.4 Newtons (N). For this reason, when the holding part 24 is shaken up and down and the arm 31 is resonated, an appropriate load acts on the user and an effective training effect can be obtained. On the other hand, when the load is 7.4 N or more, the load is too high and it is difficult to shake.

  Below, the verification result of the effect | action of the facial muscle training tool 21 of embodiment is demonstrated based on Tables 1-6. In this verification, various elastic plates 22 described later shown in FIG. A projecting portion 223 is formed at an intermediate portion in the length direction of the elastic plate 22. Various weights (not shown) described below are detachably attached to both ends of the elastic plate 22 with screws, clips, or the like.

  In Table 1, there are three types of elastic plates 22 having a thickness of 0.6 millimeters (mm), 0.8 mm, and 1.0 mm, and lengths of 300 mm, 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm. Therefore, a total of 21 types of elastic plates 22 were prepared. Then, five types of weights having weights of 6.0 grams (g), 11.5 g, 23.5 g, 48.0 g, and 92.0 g are prepared, and these are attached to both ends of the 21 types of elastic plates 22. A sample 120 of 105 types was attached (see FIG. 20B). 20B, the protrusion 223 of the elastic plate 22 is sandwiched by the Matsudaira type vibration tester 103 manufactured by Ito Seiki Co., Ltd. Table 1 shows the applied vibration frequency per second when vibration is applied and the largest amplitude is generated in the left and right arms of the elastic plate 22. The value of the applied frequency when resonance occurred was in accordance with the display on the display unit (not shown) of the vibration testing machine 103. Moreover, the presence or absence of resonance followed the visual observation.

  Then, the above-described various samples 120 are removed from the vibration testing machine 103, and the mouthpiece 41 having the same size and hardness as the holding portion 24 is attached to the protruding portion 223 of the elastic plate 22, and the sample 120 is set to 10 A sensation test was conducted by a number of subjects, and the results were ranked in four stages as shown in Table 2. The four stages are the results that 6 or more subjects felt that they could not resonate (Rank 4), were difficult to resonate (Rank 3), resonated easily (Rank 2), and particularly resonated (Rank 1). Followed. “Cannot resonate” indicates that the arm 31 cannot be resonated, and “Difficult to resonate” indicates that it is possible to resonate, but it is necessary to learn to resonate. Note that “not measurable” in Table 1 indicates that the resonance frequency was not found because it was out of the measurement range of the measuring instrument. Therefore, it has been confirmed that there are those in which the arm of the elastic plate 22 resonates even when the frequency per second is 1.17 or less.

As is clear from Tables 1 and 2, when the mouthpiece 41 vibrates at a frequency of less than 6.50 hertz (Hz), in the case of the sample 120 in which the arm of the elastic plate 22 resonates, Although it is difficult to resonate, the arm can resonate and can be used for facial muscle training. In the case of the sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency of less than 5.00 Hz, the user can easily resonate the arm, which is preferable. In the case of the sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency of less than 3.50 Hz, the user can resonate the arm more easily, which is particularly preferable.

  In the case of the sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency exceeding 4.67 Hz under the above conditions, the user can resonate although it is difficult for the user to resonate the arm. It can be used for facial muscle training. In the case of the sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency exceeding 3.33 Hz, the user can easily resonate the arm and can be used for facial muscle training. . In the case where the mouthpiece 41 is the sample 120 whose arm resonates at a frequency of 1.17 Hz or higher, the arm is particularly likely to resonate, which is particularly preferable.

  Although it is possible to resonate even if the frequency is less than 1.17 Hz, it is not preferable because the number of times the arm vibrates per second is small and the motion effect is low. Although the mouthpiece 41 is difficult to resonate in the case of the sample 120 in which the arm resonates at a frequency of 6.33 Hz or less, the user can resonate the arm and can be used for facial muscle training. . It is preferable that the sample 120 is such that the arm resonates when the mouthpiece 41 vibrates at a frequency of 4.67 Hz to 3.50 Hz. It is particularly preferable that the sample 120 is such that the arm resonates when the mouthpiece 41 vibrates at a frequency of 3.33 Hz to 1.17 Hz. A sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency of 1.17 Hz to 3.40 Hz is also preferable. It may be the sample 120 whose arm is resonated when the mouthpiece 41 vibrates at a frequency of 1.17 Hz to 4.80 Hz. The sample 120 whose arm resonates when the mouthpiece 41 vibrates at a frequency of 1.17 Hz to 6.40 Hz can be trained.

  Furthermore, from another viewpoint, the sample 120 whose arm is resonated when the mouthpiece 41 vibrates at a frequency in the range of 6.33 to 1.17 Hz can be used for training. The arm is resonated when 24 vibrates at a frequency in the range of 6.33 to 5.0 Hz. It is also preferable for the sample 120 whose arm resonates when the mouthpiece 41 vibrates at a frequency in the range of 6.33 to 3.50 Hz. More preferably, the sample 120 is such that the arm resonates when the mouthpiece 41 vibrates at a frequency in the range of 4.67 to 1.17 Hz.

  Table 3 shows three types of elastic plates 22 having a thickness of 0.6 mm, 0.8 mm, and 1.0 mm, and a total length of 18 types of elastic plates 22 having a total length of 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm. 90 types of samples 120 were combined with five types of weights of 6.0 g, 11.5 g, 23.5 g, 48.0 g, and 92.0 g. Then, as shown in FIG. 18, the bending amount a of the left and right arms of the elastic plate 22 in the natural state is measured in mm, and the numerical value is expressed as a ratio to the arm length b of the elastic plate 22, that is, the bending rate. 3. Then, these various samples 120 were subjected to a bodily sensation test by 10 subjects in the same manner as described above, and the results were ranked in four stages in Table 4 as in Table 2.

Therefore, the user can resonate the arm when the bending rate of the arm in a stationary state is the sample 120 exceeding 4.8%. In the case of the sample 120 having a deflection rate exceeding 8.1%, the arm is likely to resonate, which is preferable. In the case of the sample 120 having a deflection rate exceeding 15.0%, the arm is particularly easily resonated, which is further preferable. Further, although it is difficult to resonate when the deflection rate is less than 8.3%, it can be resonated. When the bending rate is less than 15.2%, it is preferable because resonance easily occurs. In the case where the deflection rate is less than 60.8%, it is particularly preferable because resonance easily occurs.

  From another point of view, resonance can be achieved when the deflection rate is 5.0% to 60.8%. More specifically, the resonance can be achieved when the deflection rate is 5.0% to 8.1%, and the resonance can be easily performed when the deflection rate is 8.3% to 60.8%. It was shown that the resonance was easy when the ratio was from 3% to 15.0% and less than 48.8% to 60.8%, and the resonance was particularly easy when the ratio was from 15.2% to 48.8%. As described above, when the deflection rate is 60.8%, it is easy to resonate. However, if the deflection rate greatly exceeds 60.8%, the movement of the mouthpiece 41 becomes difficult to be transmitted to the elastic plate 22, and resonance occurs. It is guessed that it is difficult to do. It is easy to resonate even when the deflection rate is 15.1% to 60%. It is easy to resonate even when the deflection rate is 8.2% to 60.0%. Furthermore, it is possible to resonate even when the deflection rate is 4.9% to 60.0%.

  In Table 5, there are a total of 18 types of elastic plates, three types having a thickness of 0.6 mm, 0.8 mm, and 1.0 mm, and six types having a total length of 400 mm, 500 mm, 600 mm, 700 mm, 800 mm, and 1000 mm, as described above. 90 and 120 types of samples 120 in combination with 5 types of weights having a weight of 6.0 g, 11.5 g, 23.5 g, 48.0 g, and 92.0 g. Then, as shown in FIG. 20 (b), the protruding portion 223 of the elastic plate 22 is sandwiched from above and below by the vibration tester 103, and the elastic plate 22 is held by the vibration tester 103 under the same conditions as in Table 1 above. Vibrate up and down. At this time, the maximum load acting on the sample 120 was detected by the strain sensor 104. As a strain sensor, the product name Strain Gauges TYPE: FLA-5-11-3L of Tokyo Sokki Kenkyujo Co., Ltd. was used. Incidentally, the load acting on the sample 120 depends on the load of the elastic plate 22 and the weight, the repulsive force of the elastic plate 22, and the acceleration applied by the vibration. Then, the test machine 103 sets the output of the strain sensor 104 in a stationary state to zero which is a reference value, and measures the load applied to the protruding portion 223 of the elastic plate 22 from the amount of strain of the elastic plate 22 detected by the strain sensor 104. Is done. Further, the amount of gravity applied to the elastic plate 22 is added, and the maximum value of the load calculated in this way is shown in Table 5. Then, each of the samples 120 was subjected to a sensation test by 10 subjects in the same manner as described above, and the results could not be resonated (rank 3), but could not be resonated (rank 2). , It was ranked in three stages that are easy to resonate (rank 1). Table 6 shows the ranking.

As a result, the user can resonate the arm when the load is less than 7.4 N and the arm is resonated, and the user is particularly resonated when the load is less than 3.9 N and the arm is resonated. Easy to make. It can be assumed that the sample 120 whose arm is resonated with a load of less than 1.5 N is likely to resonate.

  From another viewpoint, when the load applied to the mouthpiece 41 is the sample 120 whose arm is resonated within the range of 3.9N to 7.1N, the user can resonate, and the load is 1 It is particularly easy to resonate when the sample is a sample 120 whose arm is resonated within the range of .5N to 3.8N. Resonance can also be achieved when the load is the sample 120 whose arm is resonated within the range of 1.5N to 3.85N. When the load is less than 1.5N, the arm can resonate, but the load amount is small and the exercise effect is small.

That is, in the photographs before and after use, the distance 106 between the mouth corners and the corners of the eyes of 67 subjects was measured, and the change in the distance 106 before and after use was calculated. Then, the calculation results before and after use of 67 people were averaged and plotted in FIG. As apparent from FIG. 22, after use, the distance 106 was shortened by about 0.6 mm on average, and the mouth angle was raised, and a training effect was recognized.

  FIGS. 23 (a), 23 (b), and 24 show the elevation of the cheek. That is, before and after the use of 67 people, a horizontal line 107 that passes through the intercostal notch of the ear and a horizontal line 108 that passes through the corner of the mouth are set, and the intervertebral notch is the starting point between the horizontal lines 107 and 108. The longest point 110 on the cheek contour, which was 109, was determined, and the distance from the starting point 109 to the longest point 110 was measured before and after use. However, nine persons with unclear nicks and cheek outlines were excluded from the verification target, and the data of 58 persons were averaged. In this case, as a result of training, the position of the longest point 110 is moved upward. And the change before and after use of 67 persons was calculated, and it graphed in FIG. As is clear from FIG. 23, after use, the distance was reduced by about 0.7 mm on average compared to before use, and a training effect was recognized.

  25 (a), 25 (b) and 26 show the effect of tightening the face line. That is, in the front photograph before and after use of 67 persons, the horizontal line 111 passing through the base of the nose wing leg is set, and the facial outline 112 below the horizontal line 111 is set. And while calculating the area between the said horizontal line 111 and the outline 112 before and after use, the change was calculated and it graphed in FIG. In this case, however, eleven photographs with unclear facial contours 112 were excluded from the verification target, and the data of 56 persons were averaged. As apparent from FIG. 26, an average area reduction of about 0.7 square centimeters was observed before use compared to after use.

As described above, by using the facial muscle training tool 21, the size of each part of the face is shortened, and a rejuvenation effect is recognized.
