Embodiments will be described below with reference to the drawings.
First Embodiment
As shown in FIG. 1, the facial muscle training device 21 of the first embodiment is held by the lip of the user, and the user swings the facial muscle training device 21 up and down to allow the user's mouth ring Facial muscles such as cheek muscles that connect with muscles and the orbicularis muscle, smile muscles, large zygomatic muscles, and small zygomatic muscles are trained.

  As shown in FIG. 3, FIG. 4 and FIG. 8, the face muscle training device 21 is provided with a linear band plate-like elastic plate 22 composed of a plate spring made of steel plate. As shown in FIGS. 9 and 11, a core 27 made of a hard resin such as polypropylene is fixed to a central portion in the longitudinal direction of the elastic plate 22 by molding using the elastic plate 22 as an insert. The core 27 is formed with a protrusion 272 projecting from one end of the elastic plate 22. A hollow mouthpiece 28 is removably attached to the projecting portion 272 of the core 27, and the attached mouthpiece 28 forms a holding portion 24 which is held by the lips.

  As shown in FIGS. 3, 6 and 8, the whole of the elastic plate 22 and the portion of the core 27 excluding the projecting portion 272 are molded by a coating 23 made of a synthetic resin such as polyurethane. The coating 23 is made of a softer material than the core 27. A pair of through holes 222 is formed on both end sides of the elastic plate 22 respectively. The inner through holes 222 function to allow the plastic resin to enter when molding the coating 23 and to strengthen the bond between the elastic plate 22 and the coating 23. As shown in FIGS. 5 and 6, the bush 26 is fitted in the outer through hole 222 and protrudes from both the front and back sides of the elastic plate 22. However, the bush 26 is formed at a height not exposed to the surface of the coating 23. Small holes 224 are respectively provided at both ends of the elastic plate 22. The small holes 224 also function to allow the synthetic resin to enter and to 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 plates 22 and the coverings 23 on the left and right sides of the core 27. Weights 25 are provided at the tip of the sheath 23 in the arm 31.

  Then, as shown in FIG. 1, the entire face muscle training device 21 is swung up and down by holding the holding portion 24 by the lips, based on the load of the weight portion 25 and the elasticity of the elastic plate 22 etc. Both arms 31 resonate with the swing and vibrate up and down. Here, the term “resonance” means that the arm 31 vibrates largely when vibration of a frequency within a predetermined range is applied to the holding unit 24. In particular, it is preferable that the end 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 portion 24 to train the facial muscles.

  As shown in FIGS. 9 to 13, an uneven portion 271 is formed on the outer peripheral surface of the core 27 to hold and hold the mouthpiece 28. The mouthpiece 28 is formed of a soft synthetic resin such as polyurethane that is softer and less slippery than the core 27. An uneven portion 281 engageable with the uneven portion 271 of the core 27 is formed on the inner peripheral surface of the mouthpiece 28. In the upper and lower portions of the central portion of the outer peripheral surface of the mouthpiece 28 are formed depressions 282 which are worn by the lips. As shown in FIG. 13, the outer peripheral surface of the mouthpiece 28 is formed in an elliptical shape whose major axis extends in the left-right direction at the portion of the depressed portion 282. Therefore, the curvatures at the upper and lower two positions of the recess 282 are smaller than the curvatures at the left and right two positions, and are flat. A recess 283 is formed on the outer peripheral surface of the tip of the mouthpiece 28. A spherical convex portion 284 is formed on the tip end face of the mouthpiece 28.

  A proximal end of the mouthpiece 28 is formed with a pair of flanges 285 located on both sides of the arm 31. The flange 285 protrudes from the other portion of the mouthpiece 28 and, as shown in FIG. 9, when the facial muscle training device 21 is placed on the installation surface 100 such as the upper surface of the table, the flange 285 is the installation surface. In contact with 100, the mouthpiece 28 is obliquely upward. Therefore, it is possible to maintain cleanliness by preventing the portion held by the lip of the mouthpiece 28 from coming into contact with the mounting surface 100.

  A plurality of mouthpieces 28 having different outer dimensions and the like are prepared, and the user selects an appropriate mouthpiece 28 according to the size, shape, etc. of the mouth, and fits it to the outside of the core 27. Can. The mouthpiece 28 is softer than the core 27 and has a hardness of, for example, 60 degrees in a type A durometer according to JIS (Japanese Industrial Standard) K6253. The weight of the main body of the face muscle training device 21 excluding the weight 30, that is, the main body composed of the elastic plate 22, the cover 23, the core 27, and the mouthpiece 28 is about 50 to 500 grams (g). Moreover, the weight of 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 coating 23. The two weight portions 25 are constituted by weights 30 detachably attached to the holding holes 29. Then, a plurality of types of weights 30 having different weights are prepared, and the weight 30 having an arbitrary weight is selected according to the degree of exercise required by the user and the like, and is detachably attached to the holding hole 29.

The facial muscle training device 21 of this embodiment is attached with a facial muscle training device 21 and a cover 51 constituting a facial muscle training device set.
As shown in FIG. 2, FIG. 15, FIG. 16 and FIG. 18, the cover 51 is made of synthetic resin such as transparent or translucent polypropylene, polyethylene, polyamide resin, etc. Cover pieces 53, 54 are provided. One of the cover pieces 53 and 54 constitutes a main body, and the other constitutes a lid. In this embodiment, the lower cover piece 53 in FIG. 15 is the main body and the upper cover piece 54 is a lid. The two cover pieces 53 and 54 are respectively formed in a concave shape, and a storage space 511 is formed therebetween. Then, the central portion of the holding portion 24 and the covering 23 of the facial muscle training device 21 is housed in the housing space 511, and this portion is covered by the cover 51. A hooking claw 55 is formed on one cover piece 53, and a receiving portion 56 to which the hooking claw 55 is engaged is formed on the other cover piece 54. When the cover pieces 53 and 54 are closed, the hooking hook 55 is hooked The engagement between the detent 55 and the receiving portion 56 keeps the cover 51 closed.

  Recesses 58 are formed on the side walls of both cover pieces 53 and 54. When the cover pieces 53 and 54 are closed, the recess 58 forms an opening 59 for passing the arm 31 while avoiding interference with the arm 31. The edge of the opening 59 and the outer peripheral surface of the arm 31 And a gap 60 is formed therebetween. The edge of the opening 59 is formed in an arc shape in cross section so that the edge is not formed in the opening 59, or the edge is formed thick so as to increase the contact area with the arm 31, or The formation of a thick and arc-shaped cross section can prevent the arm 31 from being damaged or scarred.

Next, a method of using the facial muscle training device 21 configured as described above will be described.
As shown in FIG. 2, when the facial muscle exercise device 21 is not in use, a cover 51 is attached to the central portion of the facial muscle exercise device 21 to cover the holding portion 24. Therefore, it is possible to keep the holding portion 24 which is a portion to be held by the lips clean. In addition, since the cover 51 has a shape substantially along the outer surface of the mouthpiece 28, the facial muscle training device 21 in the mounted state of the cover 51 can be housed in a special case, and the facial muscle training device 21 can be carried and stored. It becomes.

  In the case of training a facial muscle with the facial muscle training device 21, the cover 51 is removed. In addition, according to the degree of exercise etc. which the user of the face muscle exercise device 21 requires, while the mouthpiece 28 of a required outside dimension is attached to the core 27 beforehand, the weight required for the holding hole 29 of both weight parts 25 Weight 30 is attached. In this state, the depressed portion 282 of the holding portion 24 is worn on the lip to swing the face up and down. In this way, in a state where the weight of the facial muscle exercise device 21 acts on the lips, the weight portions 25 are resonated up and down via the elastic plate 22 made of a plate spring, and the vibration is transmitted to the holding portion 24 Be done. By this, a load is applied to the facial muscle via the lip, and the facial muscle is trained.

  In this case, the holding portion 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 device 21 is held by the lip in a cantilever state, and the load on the lip is increased. 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, the hollow portion 282 is formed in a horizontally long cross-sectional oval shape, so that the mouthpiece 28 can be held in a state in which the mouth is open. By holding the mouthpiece 28 with the mouth open, the load caused by the resonance can be transmitted to the entire orbicularis oris. In addition, since the facial muscles such as the laughing muscle are connected to the orbicularis muscle, the laughing muscle etc. can be trained through the orbicular muscle, and efficient training becomes possible.

  Since the elastic plate 22 of the facial muscle exercise tool 21 of this embodiment is molded by the coating 23 of synthetic resin, when the arm 31 bends and resonates, vibration other than the vertical vibration of the arm 31 which is to be obtained for training is obtained. Movement, for example, twisting or slight vibration of the elastic plate 22 can be suppressed. Therefore, it is possible to reduce transmission of disturbing movement to the user's lips, and the facial muscle exercise device 21 can be used comfortably. Instead of molding the whole of the elastic plate 22, a plate or sheet of synthetic resin may be adhered to one of the front and back surfaces or one of the front and back surfaces by adhesion or the like.

  The mouthpiece 28 is non-slip, and has rubber properties of appropriate hardness. For this reason, it is easy to feel and, moreover, the load due to the vibration of the arm 31 can be transmitted to the lips. If the mouthpiece 28 is too hard, the mouthpiece 28 will not fit into the lips and will not be easily worn. On the other hand, if it is too soft, it is difficult to maintain the facial muscle training device 21 in a stable state even if it is worn, and the vibration of the arm 31 is absorbed, and the load for training is reduced.

  When this facial muscle exercise device 21 is used by different users, the size and shape of the mouth are different by replacing the mouthpiece 28 on the core 27 with another mouthpiece 28 having a different external dimension or the like. Even a user can share one facial muscle training device 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 face muscle and the degree of exercise.
After training, the mouthpiece 28 can be removed from the core 27 and cleaned as needed, and the cleaned mouthpiece 28 is again attached to the core 27. Thus, the mouthpiece 28 can be kept clean and hygienic. Thereafter, the cover 51 is attached to the exercise 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 carrying or storing the exercise tool 21. When the single mouthpiece 28 removed from the core 27 is housed in the cover 51, the mouthpiece 28 can be kept clean when carrying or storing the mouthpiece 28.

Below, the manufacturing method of the facial muscle training device 21 of this embodiment is demonstrated.
First, the core 27 is injection molded at the central portion of the elastic plate 22 shown in FIG. 7 using the elastic plate 22 as an insert.

Next, the bushes 26 are fitted into the pair of through holes 222 on both end sides of the elastic plate 22. As a result, the bushes 26 are provided on the front and back sides of the elastic plate 22 in a protruding manner.
Thereafter, as shown in FIG. 6, the elastic plate 22 is set in the mold 101, and the synthetic resin to be the coating 23 is injected into the mold 101. At this time, the injection pressure does not uniformly act on the elastic plate 22 at the initial stage of injection of the synthetic resin, and the pressure temporarily acts on the elastic plate 22 unevenly. For this reason, the elastic plate 22 is curved, and there is a possibility that the molding surface of the cavity 102 of the mold 101 may be scratched or the like due to the edge or the like of the end edge. However, in the present embodiment, when the elastic plate 22 is curved, it is avoided that the bush 26 abuts on the molding surface of the cavity and the elastic plate 22 abuts.

  Accordingly, the possibility of the molding surface of the cavity 102 being damaged can be prevented. In the state where the synthetic resin is completely filled in the cavity 102, since the injection pressure acts uniformly on the entire elastic plate 22, the curve of the elastic plate 22 returns to its original state, and the elastic plate 22 is in the cavity 102. It extends linearly in the central part. Therefore, after the molding is completed, the elastic plate 22 is molded in place in the molded coating 23.

  By the way, in the face muscle training device 21 of the present embodiment, when the holding portion 24 is held up with the lips and swung up and down, the arms 31 on both sides resonate while being bent. In this case, in the present embodiment, the length of the arm 31, the weight of the weight portion 25, the elasticity, so that the arm 31 resonates when the holding portion 24 vibrates at a frequency 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 hold the lip and make the arm 31 resonate, and the load can be used to perform effective training. On the other hand, at a frequency above 6.50 Hz, that is, when the holding portion 24 is reciprocated little by little, since the arm 31 is not resonated, it becomes the same as the state of vibrating the rigid body which does not bend, The load generated by the resonance of the arm 31 is not transmitted to the lip, and an effective training effect can not be obtained.

  Further, in the face muscle training device 21 of the present embodiment, the downward deflection ratio of the arm 31 in the stationary state, that is, the downward deflection 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% (%). For this reason, when the holding part 24 is vibrated up and down, the arm 31 bends appropriately 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 rigidity of the arm is high and it is difficult to bend, it is difficult to resonate, so it is difficult to obtain an effective training effect.

  Furthermore, in the face muscle training device 21 of the present embodiment, the load applied to the holding portion 24 when the 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 made to resonate, a suitable load acts on a user and an effective training effect can be acquired. 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 device 21 of embodiment is demonstrated based on Table 1-Table 6. FIG. In this verification, various elastic plates 22 described later shown in FIG. 20A were used. A projecting portion 223 is formed at an intermediate portion in the longitudinal direction of the elastic plate 22. In addition, various weights (not shown) described later are detachably attached to both ends of the elastic plate 22 with screws, clips, and the like.

  In Table 1, seven types of elastic plates 22 having a thickness of 0.6 mm (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, prepare five types of weights having weights of 6.0 g (g), 11.5 g, 23.5 g, 48.0 g, and 92.0 g, and put them on both ends of the 21 types of elastic plates 22. It was attached, and it was set as 105 types of samples 120 (refer FIG.20 (b)). Then, as shown in FIG. 20 (b), the projecting portion 223 of the elastic plate 22 is held by a Matsudaira type vibration tester 103 manufactured by Ito Seiki Co., Ltd., and various kinds of amplitude 20 mm in the vertical direction with respect to the sample 120. Table 1 shows the applied frequency per second when vibration was applied and the largest amplitude occurred in the left and right arms of the elastic plate 22. The value of the applied frequency when the resonance occurred was in accordance with the display on the display unit (not shown) of the vibration tester 103. Moreover, the presence or absence of resonance followed visual observation.

  Then, the various samples 120 described above were removed from the vibration tester 103, and the mouthpiece 41 was attached to the projecting portion 223 of the elastic plate 22. The mouthpiece 41 has the same size and hardness as the holding portion 24 and corresponds to the holding portion 24. Such a sample 120 was subjected to a sensation test by 10 subjects, and the results were ranked in four stages as shown in Table 2. In the four stages, six or more subjects felt that it was not possible to resonate (rank 4), hard to resonate (rank 3), easy to resonate (rank 2), especially easy to resonate (rank 1) I obeyed. "Can not resonate" indicates that the arm 31 can not resonate, and "hard to resonate" indicates that the arm 31 can resonate but it requires learning to resonate. In addition, since "measurement impossible" in Table 1 was out of the measurement range of a measuring instrument, it shows that the frequency which resonates was not clarified. Therefore, it is confirmed that some arms of the elastic plate 22 resonate even if the frequency per second is 1.17 or less.

  As apparent from Tables 1 and 2, in the case of the sample 120 in which the arm of the elastic plate 22 resonates when the mouthpiece 41 vibrates at a frequency of less than 6.50 Hertz (Hz), the user Although it is difficult to resonate, it is possible to resonate the arm, and it is possible to use it for facial muscle training.

  In the case of the sample 120 in which the arm is resonated 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 where the arm is resonated when the mouthpiece 41 vibrates at a frequency of less than 3.50 Hz, the user can more easily resonate the arm, which is particularly preferable.

  Then, under the above conditions, in the case of the sample 120 in which the arm is resonated when the mouthpiece 41 vibrates at a frequency above 4.67 Hz, the user can resonate although it is difficult to resonate the arm It can be used to train the face muscles.

  In the case of the sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency higher than 3.33 Hz, the user can easily resonate the arm and can be used for facial muscle training. is there. In the case of the sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency of 1.17 Hz or more, the arm is particularly easily resonated, which is particularly preferable. Even if it is less than 1.17 Hz, it is possible to resonate, but it is not preferable because the number of times the arm vibrates per second is small and the movement effect is low.

  In the case of the sample 120 in which the arm resonates when the mouthpiece 41 vibrates at a frequency of 6.33 Hz or less, although it is difficult to resonate, the user can resonate the arm and provides facial muscle training. It is possible.

  It is preferable that the sample 120 is such that the arm is resonated when the mouthpiece 41 vibrates at a frequency of 3.50 Hz or more and 4.67 Hz or less. It is particularly preferable that the arm is a sample 120 that is resonated when the mouthpiece 41 vibrates at a frequency of 1.17 Hz or more and 3.33 Hz or less.

  The sample 120 is also preferred, in which the arm is resonated when the mouthpiece 41 vibrates at a frequency of 1.17 Hz or more and 3.40 Hz or less. The sample 120 may be one in which the arm is resonated when the mouthpiece 41 vibrates at a frequency of 1.17 Hz or more and 4.80 Hz or less. It is also possible to exercise the sample 120 in which the arm is resonated when the mouthpiece 41 vibrates at a frequency of 1.17 Hz or more and 6.40 Hz or less.

  Furthermore, viewed from another point of view, the sample 120 in which the arm is resonated when the mouthpiece 41 vibrates at a frequency within the range of 1.17 Hz to 6.33 Hz can be used for training. When the mouthpiece 41 vibrates at a frequency within a range of 5.0 Hz or more and 6.33 Hz or less, the arm is resonated.

  It is also preferable in the case of the sample 120 in which the arm is resonated when the mouthpiece 41 vibrates at a frequency within the range of 3.50 Hz or more and 6.33 Hz or less. More preferably, the sample 120 is such that the arm is resonated when the mouthpiece 41 vibrates at a frequency within the range of 1.17 Hz to 4.67 Hz.

  Table 3 is a total of 18 types of elastic plates 22 with six types of thickness of 0.6 mm, 0.8 mm and 1.0 mm, and 6 types of total length of 400 mm, 500 mm, 600 mm, 700 mm, 800 mm and 1000 mm. 90 types of samples 120 were obtained in combination 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 deflection amount a of the left and right arms of the elastic plate 22 in the natural state is measured in mm units, and the numerical value is shown as a ratio to the length b of the arm of the elastic plate 22; As noted in 3. Then, these various samples 120 were subjected to a sensation test by 10 subjects in the same manner as described above, and the results were ranked in four stages in Table 4 in the same manner as in Table 2 above.

  Therefore, the user can resonate the arm when the deflection rate in the stationary state of the arm is the sample 120 which exceeds 4.8%. In the case of the sample 120 having a deflection rate of more than 8.1%, the arm is easily resonated, which is preferable. In the case of the sample 120 whose deflection rate exceeds 15.0%, the arm is particularly easily resonated, which is more preferable. Moreover, although it is hard to resonate when a bending rate is less than 8.3%, it can be made to resonate. If the deflection rate is less than 15.2%, resonance is likely to occur, which is preferable. In the case where the deflection rate is less than 60.8%, it is particularly preferable to be easily resonated.

  From another point of view, resonance can be achieved when the deflection rate is 5.0% to 60.8%. Furthermore, in detail, it is possible to resonate when the deflection rate is 5.0% to 81%, and easily resonate when the deflection rate is 8.3% to 60.8%, 8 The results show that resonance occurs easily in the cases of 3% to 15.0% and 60.8%, and in particular, in the case of 15.2% to 48.8%. As described above, although it is easy to resonate when the deflection rate is 60.8%, if the deflection rate greatly exceeds 60.8%, the movement of the mouthpiece 41 is hardly transmitted to the elastic plate 22. It is assumed that it is difficult to resonate.

  In Table 5, in the same manner as described above, a total of 18 types of elastic plates having three types of 0.6 mm, 0.8 mm and 1.0 mm, and 6 types of total lengths of 400 mm, 500 mm, 600 mm, 700 mm, 800 mm and 1000 mm. Ninety types of samples 120 were obtained by combining 22 and five types of weights having weights 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 projection 223 of the elastic plate 22 is sandwiched from above and below by the vibration tester 103, and the vibration tester 103 is used to hold the elastic plate 22 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 distortion sensor, the product name Strain Gauges TYPE: FLA-5-11-3L of Tokyo Sokki Kenkyusho 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 tester 103 sets the output of the strain sensor 104 in the stationary state to zero, which is a reference value, and measures the load applied to the projecting portion 223 of the elastic plate 22 from the strain amount of the elastic plate 22 detected by the strain sensor 104 Be done. Further, the action of gravity applied to the elastic plate 22 is added, and the maximum value of the load calculated in this manner is shown in Table 5. Then, using each sample 120, a sensation test is performed by 10 subjects in the same manner as described above, and the result can not be resonated (rank 3), but it is difficult to resonate, but is possible (rank 2) It was ranked in 3 stages of easy to resonate (rank 1). Table 6 shows the rankings.

  As a result, the user can resonate the arm in the case of the sample 120 in which the load is less than 7.4 N and the arm is resonated, and particularly in the case of the sample 120 in which the load is less than 3.9 N and the arm is resonated. It is easy to do. In addition, it can be inferred that the case where the load is less than 1.5 N and the arm is resonated is also easy to resonate.

  From another point of view, if the load applied to the mouthpiece 41 is the sample 120 to which the arm is resonated within the range of 3.9 N to 7.1 N, the user can resonate the arm, In particular, when the arm is a sample 120 to be resonated within the range of 1.5 N to 3.8 N, the arm is easily resonated. The arm can be made to resonate also when the load is the sample 120 to which the arm is resonated within the range of 1.5N to 3.85N. When the load is less than 1.5 N, the arm can be resonated, but the amount of load is small and the exercise effect is small.

  Therefore, if various conditions such as the length of the arm 31 of the facial muscle training device 21 and the weight of the weight 30 are set arbitrarily, the facial muscle training device 21 showing various behaviors described in Tables 1 to 6 Is embodied. Such a facial muscle training device 21 can obtain the same function as the verification result.

  Table 7 shows the elastic plates 22 used in the various tests described above, having three types of thicknesses of 0.6 mm, 0.8 mm and 1.0 mm, and full lengths of 300 mm, 400 mm, 500 mm, 600 mm and 700 mm. The spring constant (g / mm) of a total of 21 types of elastic plates 22 of 7 types of 800 mm and 1000 mm are described. As apparent from Table 7, the lowest spring constant is 0.23 g / mm and the highest spring constant is 39.35 g / mm. The present invention is not limited to these spring constants, and any spring constant can be set. Then, it is possible to embody the facial muscle training device using the elastic plate 22 of the spring constant of Table 7 or an arbitrary spring constant. The arbitrary spring constant is the numerical spring constant that fills in between each numerical value of the spring constant in Table 7, and the spring constant of the value that exceeds the value of the maximum spring constant in Table 7 or the value of the minimum spring constant. It is.

In the case of this configuration, although not shown, the elastic plate 22 is preferably provided with the through hole 222 and the bush 26, and the bush 26 is preferably provided at the tip of the large area portion 122.

In this embodiment, the number of parts is reduced, and the configuration is simplified.
Third Embodiment
Next, a third embodiment of the present invention will be described with reference to FIGS. 21 to 26, focusing on the differences from the above-described embodiments.

  As shown in FIGS. 21 and 22, a large area portion 122 made of the coating 23 is formed on both ends of the coating 23. The elastic plate 22 is formed to have a length reaching the central portion of the large area portion 122. The elastic plate 22 is formed such that its thickness dimension and width dimension gradually decrease from the longitudinal center to the tip.

  As shown in FIGS. 22 and 23, weight pieces 330 made of a metal plate are embedded at both ends of the large-area portion 122 of the face training tool. The weight piece 330 is formed with one first through hole 331 and a pair of second through holes 332, and the second through holes 332 are located in the sheath 23. The synthetic resin forming the coating 23 enters the second through holes 332, and the bonding strength between the weight piece 330 and the coating 23 is secured. Notches 333 are formed at both ends of the coating 23 on both the front and back sides of the weight piece 330, and the first through holes 331 are located in the notches 333.

  A decorative clip 334 made of synthetic resin is fitted in the notch 333. The decorative clip 334 is colored in a color different from that of the coating 23, and its outer surface is continuous with the outer surface of the coating 23. . As shown in FIG. 24 to FIG. 26, in the decorative clip 334, a pair of sandwiching pieces 335 are connected via the connecting portion 338, and the sandwiching pieces 335 are formed in a side acute angle as a whole. A clamping projection 336 is formed at the base of both clamping pieces 335, and the weight piece 330 is clamped by these clamping projections 336. Fitting projections 337 are formed on the inner surfaces of the tips of the two holding pieces 335, respectively. The fitting projection 337 is fitted in the first through hole 331 of the weight piece 330. The decorative clip 334 is fixed to the weight piece 330 by this fitting.

The facial muscle training device 21 configured as described above is used in the same manner as the facial muscle training device 21 of the embodiment.

(1) Since the weight separate from the main body as in the first embodiment is not provided, the number of parts is reduced, and the manufacturing cost can be reduced.
(2) Weight pieces 330 are embedded at both ends of the arm 21. Therefore, the weight of the weight piece 330 can be used to greatly vibrate the both end portions of the arm 21 and training can be performed effectively.

  (3) A space is provided between both ends of the arm 21 and the weight piece 330. For this reason, the synthetic resin in this space portion is easily bent, and both ends of the arm 21 are easily vibrated by using this bending, and forging can be effectively performed by using this characteristic. In addition, since a space is provided between both ends of the arm 21 and the weight piece 330, even if a small vibration that does not contribute much to wrought is generated in the weight piece 330 or the coating 23 around it due to the movement of the weight piece 330. Part or most of the vibration is absorbed by the coating 23 of the part of the space. Therefore, the bending motion of the arm 21 becomes flexible and easy to use.

  (4) Since the thickness dimension and width dimension of the elastic plate 22 are formed so as to gradually decrease from the longitudinal center to the tip, both ends of the elastic plate 22 are easily bent. Therefore, both ends of the arm 21 can be vibrated to a large extent, and the elasticity of both ends of the elastic plate 22 can be used effectively to perform forging.

  (5) When forming the coating 23, the weight piece 330 is held in a hollow state by the core clip in a mold (not shown). And the notch 333 which the weight piece 330 exposed is formed in the both ends of the coating | cover 22 by demolding accompanying completion | finish of shaping | molding. Therefore, the notch 333 can be used to easily attach the decorative clip 334 as an accent on the design.
