Also, the configuration of the mouthpiece 18 is the same except for a concave portion (not shown) corresponding to the projection 55, which will be described later.

As shown in FIGS. 3 to 5, the mounting portion 20 on the rear side of the core 17 has an outer shape of substantially a quadrangular prism with curved corners and a spherical rear end surface. A base portion 31 of the front end portion is formed into a cone shape. The mounting portion 20 is formed with a hollow portion 32 having an open top surface or a bottom surface (bottom surface in the embodiment). A vertical wall 33 and a horizontal wall 34 are formed in the hollow portion 32 for reinforcement. These vertical walls 33 and horizontal walls 34 cross each other. A large diameter portion 37 is formed on the rear side of the mounting portion 20 . A small diameter portion 38 is formed on the front side of the large diameter portion 37 via steps 35 and 36 on both upper and lower surfaces and both side surfaces of the mounting portion 20 . A step 35 on the lower surface is formed in the vertical wall 33 . Except for the step 35 on the lower surface, the steps 35 and 36 have a curved shape in which the central portion recedes. The height of the steps 35, 36 is within the range of 0.3 to 1 mm (millimeters).

As shown in FIGS. 4 and 6 , the mouthpiece 18 has an opening formed in the front surface of the internal space 43 and has a peripheral wall portion 41 and a bottom wall portion 42 . On the outer circumference of the mouthpiece 18, approximately circular fold-like protrusions 23, 24, and 25 are formed at three locations spaced apart from each other in the front-rear direction. An annular recess 26 to be bitten is formed.

As shown in FIGS. 3, 4 and 6, the inner space 43 of the mouthpiece 18 has a shape substantially similar to the shape of the outer peripheral surface of the mounting portion 20, and the inner surface of the bottom wall portion 42 has a spherical shape. there is A tapered widening portion 44 is formed along the base portion 31 at the opening of the internal space 43 . A narrowed portion 45 is formed at a position corresponding to the annular concave portion 26 in the inner portion of the expanded portion 44 . An extended portion 46 is formed in the deep portion of the narrowed portion 45 . A plurality of vertical ribs 47 extending in the front-rear direction are formed on the inner wall surface of the extended portion 46 at four positions corresponding to the upper and lower surfaces and both side surfaces of the mounting portion 20 . The height of the vertical rib 47 is the same as the inner peripheral surface of the narrowed portion 45 or lower than the inner peripheral surface.

As shown in FIGS. 3 , 4 , 6 and 7 , an annular protrusion extending along the peripheral surface of the peripheral wall portion 41 is provided at the end of the narrowed portion 45 on the expanded portion 46 side. A lateral rib 48 is formed. This transverse rib 48 is located behind the annular recess 26 which is held by the lips. The height of the horizontal rib 48 slightly protrudes from the inner peripheral surface of the narrowed portion 45 and is formed substantially equal to the height of the steps 35 and 36 . Accordingly, the height of the transverse ribs 48 is within the range of 0.3-1 mm. The lateral rib 48 is formed with curved portions 49 and 50 having shapes corresponding to the steps 35 and 36 . As shown in FIG. 8, the angle .theta.1 of the first slope 481 of the horizontal rib 48 on the narrowed portion 45 side is larger than the angle .theta.2 of the second slope 482 on the expanded portion 46 side. Also, the rising length of the second slope 482 (in the vertical direction in FIG. 8) is longer than the rising length of the second slope 482 .

As shown in FIG. 11, in the second type of facial muscle training tool 21, a protrusion 55 is formed at the rear end of the mounting portion 20, and a recess (not shown) is formed at the deep inner portion of the mouthpiece 18. When the mouthpiece 18 is attached to the attachment portion 20, the projection 55 and the recess are fitted.

A plurality of types of mouthpieces 18 having different shapes and sizes are prepared, and an appropriate mouthpiece 18 is selected according to the size and shape of the mouth of the user.
The mouthpieces 18 of the first and second types of facial muscle training tools 11 and 21 constructed as described above act as follows.

When these facial muscle training tools 11 and 21 are used, the mouthpiece 18 is externally fitted to the mounting portion 20 of the core 17 .
In this state, as shown in FIGS. 1 and 9, the facial muscles are trained by holding the mouthpiece 14 to the lips and reciprocating the face up and down. In this case, since the horizontal ribs 48 are engaged with the steps 35, 36 of the mounting portion 20, the mouthpiece 18 remains on the mounting portion 20 at a predetermined position even if the facial muscle training tools 11, 21 are reciprocated up and down. It is possible to prevent it from being detached from its position, displaced from its position, or coming off.

Also, when the mouthpiece 18 is washed or the facial muscle training tool 21 is used by a different user, the mouthpiece 18 is removed, and the mouthpiece 18 after washing or a mouthpiece of a different size is used. 18 is reattached.

In the case of this attachment, as described above, the horizontal rib 48 is almost equal to the height of the steps 35 and 36, and is not so high. It deforms and climbs over the step 35. - 特許庁Therefore, the mouthpiece 18 can be easily removed. Also, when a new mouthpiece 18 is attached to the core 17, the height of the horizontal ribs 48 is not so high. The movement of the mouthpiece 18 is not greatly resisted, and the mouthpiece 18 can be easily attached.

Therefore, according to the configuration of the first embodiment, the following effects can be obtained.
(1) The height of the horizontal rib 48 is formed as low as the height of the steps 35 and 36 . Therefore, when the mouthpiece 18 is attached to the core 17 of the mouth-holding portion 14 prior to use of the facial muscle training tools 11 and 21, the lateral ribs 48 provide great resistance to the attachment of the mouthpiece 18. Therefore, the mouthpiece 18 can be easily attached.

(2) The angle θ1 of the first slope 481 of the lateral rib 48 that contacts the distal end portion of the core 17 and the outer peripheral surface of the core 17 is formed to be large when it is attached to the attachment portion 20 . Therefore, the lateral ribs 48 do not create a large resistance to the mounting of the mouthpiece 18 , and the mouthpiece 18 can be easily attached to the mounting portion 20 of the core 17 .

(3) Since the expanded portion 46 is formed behind the narrowed portion 45 of the mouthpiece 18, the end of the narrowed portion 45 on the side of the expanded portion 46 tends to widen. Therefore, when the mouthpiece 18 is attached to the attachment portion 20, the mouthpiece 18 can be easily attached even if the diaphragm portion 45 has the lateral ribs 48 formed thereon.

(4) When the mouthpiece 18 is attached to the mounting portion 20 at a predetermined position, the horizontal ribs 48 drop into the steps 35 and 36 of the core 17 and engage with the steps 35 and 36 . Therefore, in this state, when the face is reciprocated up and down with the mouth-holding portion 14 held in the mouth, the core 17 is disengaged due to the engagement between the lateral ribs 48 and the steps 35 and 36 as described above. The mouthpiece 18 is prevented from slipping out of. In particular, in the second type facial muscle training device 21, the weight portion may be swung left and right. Since it is formed correspondingly, the mouthpiece 18 is appropriately prevented from coming off even in such a case. In addition, since the horizontal rib 48 is positioned on the bottom wall portion 42 side behind the annular recess 26 that is held by the lips, the presence of the horizontal rib 48 is felt by the user when the annular recess 26 is held. You can get a good feeling of use.

(5) A vertical rib 47 is formed on the inner surface of the extended portion 46, and the vertical rib 47 engages the outer peripheral surface of the large-diameter portion 37 of the core 17. Therefore, even if the extended portion 46 is formed, the mouthpiece is A portion of the eighteen extensions 46 can be adequately retained against the core 17 . Further, when the user pinches the expanded portion 46 instead of the annular recess 26, the engagement between the longitudinal rib 47 and the large-diameter portion 37 prevents deformation of the pinched portion. , it is possible to avoid giving a sense of discomfort to the user.

(6) When using the facial muscle training tools 11 and 21, the annular concave portion 26 of the mouthpiece 18 corresponds to the narrowed portion 45, and the narrowed portion 45 has a smaller diameter on the front side of the steps 35 and 36 of the core 17. Since the mouthpiece 18 is engaged with the portion 38 by wrapping around it, the mouthpiece 18 is stably fitted onto the core 17 and is easy to use.

(7) Since the angle θ2 of the second slope 482 on the side of the steps 35 and 36 of the core 17 is smaller than the angle θ1 of the first slope 481 on the opposite side, and the height of the second slope 482 is high, the mouthpiece 18 The mouthpiece 18 is hard to come off unless you pull it backward. Thus, as noted above, the mouthpiece 18 is held in place for ease of use.

(8) The lateral rib 48 is positioned at the rear end of the constricted portion 45, in other words, at the rear end of the annular recess 26 that is held by the user. Therefore, when the annular recess 26 is engaged, a force acts in the direction of narrowing the inner diameters of the constricted portion 45 and the lateral ribs 48, making it difficult for the mouthpiece 18 to come off during use, making it easy to use. Become.

(9) Since the steps 35 and the lateral ribs 48 are curved, their contact areas are widened, and the mouthpiece 18 is more reliably prevented from coming off.
(10) When removing the mouthpiece 18 for cleaning or replacement of the mouthpiece 18, as described above, since the height of the horizontal ribs 48 is not so high, a certain amount of force is applied to the mouthpiece 18. is applied in the pulling direction, the lateral rib 48 is deformed to climb over the step 35 . Therefore, the mouthpiece 18 can be removed without strong resistance.

(11) Since the lateral ribs 48 are formed on the inner peripheral surface of the mouthpiece 18 without being exposed to the outside, the lateral ribs 48 can be prevented from being damaged or worn by external factors as much as possible. The function of the lateral ribs 48 such as holding action of the piece 18 can be maintained for a long period of time.

(12) The tip of the mouthpiece 18 is closed by the bottom wall 42 . Therefore, when the mouthpiece 18 is attached to the attachment portion 20 of the core 17, the inside of the mouthpiece 18 can be kept clean, and the tip of the core 17 is also closed by the bottom wall portion 42, so the core 17 is also kept clean. can be maintained. In addition, the bottom wall portion 42 prevents the mouthpiece 18 from moving toward the base portion 31 of the core 17 more than necessary, so that the mouthpiece 18 can be mounted at a predetermined position. can avoid unnecessary deformation of Therefore, the facial muscle training tool can be comfortably used without causing discomfort when the mouthpiece 18 is held in the mouth, and the durability of the mouthpiece 18 can be improved.

(13) In the second type of facial muscle training tool 21, the mating projection 55 and recess are provided at the contact portion between the rear end of the core 17 and the bottom wall portion 42 of the mouthpiece 18. It is possible to prevent erroneous assembly of mouthpieces 18 of different types of facial muscle training tools 11 that do not have recesses and mouthpieces with different positions of recesses.
