Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, for example, postural collapses such as pelvic retroversion due to the decline of trunk muscle strength, flat back posture due to ethnic skeletal characteristics, and hunchback, swayback, and excessive forward bending of the lumbar vertebrae caused by lifestyle habits and the like may deteriorate the physical health state, and it is desired to habituate the maintenance of an appropriate posture. However, it may be difficult for each person to be conscious of an appropriate posture itself, and it may be difficult to carry out specific attempts to realize an appropriate posture. For example, according to the above-mentioned conventional support, there is no suggestion as to what kind of force should be externally applied to the lumbar vertebrae or the pelvis in order to realize an appropriate posture of the body trunk, and there arises a problem that the specific action required to improve the posture of the body trunk is unclear.

[0005] An object of the present invention is to provide a body trunk wearer that can properly guide and improve the posture of the body trunk.

Means for Solving the Problems

[0006] In order to solve the above problems and achieve the above object, the present invention adopts the following aspects. (1): The body trunk wearer according to one aspect of the present invention (for example, the body trunk wearers 10, 10A, 10B, 10C, 10D, 10E in the embodiment) includes at least one pressing member (for example, the pressing member 13 in the embodiment) having a convex curved surface (for example, the curved surface 13A in the embodiment) that is pressed against the waist of the human body, and a holding member (for example, the holding member 11 in the embodiment) that holds the pressing member. The pressing member uses the vertical position (for example, the vertical position H (L4-S2) in the embodiment) between the fourth lumbar vertebra and the second sacral vertebra of the human spine as the action point (for example, the action point P in the embodiment), and inclines from the upper rear side to the lower front side with respect to the front-rear direction of the human body, and generates a force (for example, the force F in the embodiment) in a direction penetrating between the fifth lumbar vertebra and the second sacral vertebra (for example, the angular range θ (L5-S2) in the embodiment) of the spine.

[0007] (2): The body trunk wearer according to (1) above may include a plurality of the pressing members arranged on both sides in the left-right direction with respect to the spine when viewed along the front-rear direction of the human body.

[0008] (3): In the body trunk wearer according to (1) above, the holding member may be a belt-like member that is wound from the waist toward the abdomen.

[0009] (4): The body trunk wearer according to (3) above may have a surface (for example, the inner surface 31A in the embodiment) that is pressed against the abdomen, and may include at least one abdomen-side pressing member (for example, the abdomen-side pressing member 31 in the embodiment) that is held by the holding member.

[0010] (5): The trunk wearing device described in (4) above may be held by the holding member between the waist and the abdomen, and may include at least one pressure dispersion member (for example, the pressure dispersion member 33 in the embodiment) that disperses the pressure acting on the human body from the holding member.

[0011] (6): In the trunk wearing device described in (1) above, the pressing member may include a flat contact surface (for example, the flat surface 13B in the embodiment) that contacts the holding member and on which the pressure from the holding member acts.

[0012] (7): In the trunk wearing device described in (6) above, the pressing member may include an angle regulating member (for example, the second protruding portions 61c and 63c in the embodiment) that protrudes in a direction along the contact surface and regulates the inclination angle (for example, the angle θ in the embodiment) of the pressing member with respect to the vertical direction of the human body when pressed against the waist.

[0013] (8): In the trunk wearing device described in any one of (1) to (7) above, the holding member may include a positioning member (for example, the positioning member 21 in the embodiment) that adjusts the position of the pressing member, and a pressing member (for example, the pressing member 23 in the embodiment) that generates a pressure to press the pressing member against the waist.

[0014] (9): The trunk wearing device described in (8) above is disposed above the pressing member and has a surface that is pressed against the waist, and uses the vertical position (for example, the vertical position H (L1 - L3) in the embodiment) between the first lumbar vertebra and the third lumbar vertebra of the spine as the action point (for example, the action point PU in the embodiment), and may include at least one upper pressing member (for example, the upper pressing member 43 in the embodiment) that generates a force in the direction along the front - rear direction of the human body, and an upper holding member (for example, the upper holding member 41 in the embodiment) that is disposed above the holding member and holds the upper pressing member.

Advantages of the Invention

[0015] According to the above (1), by providing a pressing member that generates a force in the direction penetrating from the fifth lumbar vertebra to the second sacral vertebra, the posture of the trunk can be properly induced and improved by tilting the pelvis forward or by generating a sensory stimulus. For example, by tilting the pelvis forward and standing the pelvis in a so-called intermediate position, the posture of the trunk can be properly induced and improved. Also, for example, by generating a sensory stimulus such as bone stimulation due to tilting of the pelvis or bone stimulation due to pressure applied near the lumbosacral region from the fifth lumbar vertebra, a change occurs in the motor nervous system of the central nervous system, and the exerted muscle strength increases as the electromyogram potential rises, thereby enabling proper induction and improvement of the posture of the trunk. For example, while only an increase in abdominal pressure cannot increase the maximum exerted muscle strength of the lower limbs, by properly inducing and improving the posture of the trunk, the maximum exerted muscle strength of the lower limbs can be increased, and the improvement of balance ability and the correction of posture can be promoted. An appropriate trunk posture can be habituated, muscle strength and muscle mass can be easily maintained daily, and the collapse of postures such as so-called straight neck can be prevented.

[0016] In the case of the above (2), by providing a plurality of pressing members arranged on both sides in the left-right direction with respect to the spine, a force in the direction penetrating from the fifth lumbar vertebra to the second sacral vertebra can be properly generated.

[0017] In the case of the above (3), by providing a belt-like member wound from the waist toward the abdomen, the holding property of the pressing member can be improved.

[0018] In the case of the above (4), by providing an abdominal side pressing member, the direction of abdominal pressure can be set as desired, and by sandwiching the lumbar vertebra from the front and back together with the pressing member on the lumbar side, an appropriate degree of forward bending of the lumbar vertebra can be promoted. For example, the state where the pelvis tilts forward and the lumbar vertebra bends forward excessively, that is, the occurrence of an excessive curvature posture can be suppressed.

[0019] In the case of the above (5), the pressure acting from the holding member can be dispersed so as to prevent the holding member from digging into the side portion between the waist and abdomen of the human body.

[0020] In the case of the above (6), by providing a flat contact surface that contacts the holding member, the direction in which the curved surface of the pressing member is pressed against the waist of the human body can be easily regulated as desired.

[0021] In the case of the above (7), the inclination angle of the pressing member can be easily set as desired, for example, compared to the case where the angle regulating member is not provided.

[0022] In the case of the above (8), by providing the positioning member and the pressing member, the positioning of the pressing member can be easily performed, and the pressure acting on the pressing member can be appropriately set.

[0023] In the case of the above (9), the upper pressing member and the upper holding member sandwich the lumbar vertebra from the front and back, thereby promoting an appropriate degree of forward bending of the lumbar vertebra. For example, it is possible to suppress the occurrence of a state where the pelvis tilts forward and the lumbar vertebra bends forward excessively, that is, an excessive curved posture.

Embodiments for Carrying out the Invention

[0025] Hereinafter, the trunk wearer according to the embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a view of the holding member 11 of the trunk wearer 10 of the embodiment as seen from the outside. FIG. 2 is a view of the holding member 11 of the trunk wearer 10 of the embodiment as seen from the inside (human body side). FIG. 3 is a perspective view of the pressing member 13 of the trunk wearer 10 of the embodiment. The trunk wearer 10 of the embodiment includes, for example, a holding member 11 and two pressing members 13 held by the holding member 11. As shown in FIGS. 1 and 2, the holding member 11 includes, for example, a positioning member 21 and two pressing members 23. The outer shape of each of the positioning member 21 and the pressing member 23 is, for example, a strip-like or belt-like shape that is wide and string-like. Each of the positioning member 21 and the pressing member 23 is formed of an elastic material such as rubber and resin, for example, to have elasticity and pressure application properties. For example, the pressure application property applies pressure to the body on which the holding member 11 is mounted and generates a pressure for pressing the pressing member 13 against the body.

[0026] For example, the length of the positioning member 21 in the longitudinal direction is formed to be at least the length required to be wound around the torso of the human body to form a loop. The positioning member 21 includes, for example, a detachable coupling member such as a hook-and-loop fastener on both surfaces (inner surface and outer surface) of a predetermined portion such as both ends in the longitudinal direction. The positioning member 21 is wound, for example, from the waist to the abdomen of the human body, and both ends in the longitudinal direction are overlapped in the thickness direction on the abdomen side, and the coupling members provided at the predetermined portions are coupled to each other, whereby the positioning member 21 is annularly mounted on the torso of the human body.

[0027] The positioning member 21 includes, for example, two member holding portions 21a for holding the two pressing members 13 at the central portion in the longitudinal direction. The two member holding portions 21a are provided, for example, on the inner surface (the surface on the human body side) at a predetermined interval in the longitudinal direction of the positioning member 21. The outer shape of each member holding portion 21a is, for example, a bag-like shape with an open upper side.

[0028] For example, the length of the pressing member 23 in the longitudinal direction is formed to be shorter than the circumference of the torso when tightening the torso. Of the first end portion and the second end portion which are both end portions in the longitudinal direction of the pressing member 23, the first end portion is fixed to the central portion in the longitudinal direction of the positioning member 21. The pressing member 23 includes, for example, a coupling member that is detachable from the positioning member 21 such as a hook-and-loop fastener on the inner surface (the surface on the human body side) of a predetermined portion such as the second end portion.

[0029] As shown in FIG. 3, the outer shape of the pressing member 13 is, for example, a plate shape having a convex curved surface 13A and a flat surface 13B on the side surface. The convex curved surface 13A is formed in a shape that rises slightly abruptly from the flat surface 13B as it goes from the first end (for example, the upper end) to the second end (for example, the lower end) of both ends (the first end and the second end) in a predetermined direction (for example, the vertical direction) along the flat surface 13B. The convex curved surface 13A is formed in a shape that, after reaching the highest height from the flat surface 13B at a position slightly shifted toward the first end side from the central portion in the predetermined direction along the flat surface 13B, heads toward the second end side along the predetermined direction and gradually decreases in height.

[0030] The pressing member 13 is formed of a hard material such as resin or metal, for example. The pressing member 13 is housed in the member holding portion 21a such that, for example, the thickness direction is parallel to the left - right direction of the human body, the curved surface 13A faces the human body side, and the flat surface 13B faces the inside of the positioning member 21. Each pressing member 13 has the curved surface 13A pressed against the waist of the human body by the pressure acting on the entire flat surface 13B from the positioning member 21 and each pressing member 23, for example.

[0031] FIG. 4 is a view showing the positions of the two pressing members 13 in a state where the body trunk wearing device 10 of the embodiment is worn on the human body. FIG. 5 is a cross - sectional view showing a state where the body trunk wearing device 10 of the embodiment is worn on the human body. As shown in FIGS. 4 and 5, the two pressing members 13 are arranged on both sides in the left - right direction with respect to the spine (so - called backbone) SP when viewed along the front - rear direction of the human body HB, for example. The curved surfaces 13A of the two pressing members 13 are pressed against the rear - side apex portions A of the left and right erector spinae muscles of the human body HB, for example.

[0032] FIG. 6 is a view showing the vertical position of the action point P of the pressing member 13 in a state where the body trunk wearing device 10 of the embodiment is worn on the human body HB. FIG. 7 is a view showing the direction of the force F acting from the pressing member 13 on the spine SP in a state where the body trunk wearing device 10 of the embodiment is worn on the human body HB. As shown in FIGS. 6 and 7, each pressing member 13 uses, for example, the vertical position H(L4-S2) between the fourth lumbar vertebra L4 and the second sacral vertebra S2 of the spine SP of the human body HB as the action point P. Each pressing member 13 inclines, for example, from the upper rear side to the lower front side with respect to the front-rear direction of the human body HB, and generates a force F in the direction passing through the angular range θ(L5-S2) between the fifth lumbar vertebra L5 and the second sacral vertebra S2 of the spine SP as viewed from the action point P. That is, the angle θ formed by the direction of the force F with respect to the downward direction in the vertical direction is less than at least 90°.

[0033] The forces F acting on the spine SP from the two pressing members 13 generate, for example, a force FR that rotates the pelvis PV with the anterior superior iliac spine as the fulcrum Q, and by tilting the pelvis PV forward, the pelvis PV is raised to a so-called intermediate position. Also, for example, due to the generation of sensory stimulation such as bone stimulation caused by the forward tilt of the pelvis PV or bone stimulation caused by pressure applied near the sacroiliac joint from the fifth lumbar vertebra L5, a change occurs in the motor nervous system of the central nervous system, and the muscle strength increases as the myoelectric potential increases. The pressure PR acting on the abdomen and sides of the body from the holding member 11 increases, for example, the abdominal pressure and generates a force FS that supports the fulcrum Q of the anterior superior iliac spine.

[0034] As described above, according to the trunk wearing device 10 of the embodiment, by providing the pressing member 13 that generates the force F in the direction passing through the section between the fifth lumbar vertebra L5 and the second sacral vertebra S2, by tilting the pelvis PV forward, the posture of the trunk can be properly induced and improved. For example, by tilting the pelvis PV forward and raising the pelvis PV to a so-called intermediate position, the posture of the trunk can be properly induced and improved. Also, for example, due to the generation of sensory stimulation such as bone stimulation caused by the forward tilt of the pelvis PV or bone stimulation caused by pressure applied near the sacroiliac joint from the fifth lumbar vertebra L5, a change occurs in the motor nervous system of the central nervous system, and the muscle strength increases as the myoelectric potential increases, so that the posture of the trunk can be properly induced and improved. For example, only increasing abdominal pressure cannot increase the maximum exertable muscle strength of the lower limbs. However, by properly guiding and improving the posture of the trunk, it is possible to increase the maximum exertable muscle strength of the lower limbs, and at the same time, promote the improvement of balance ability and the correction of posture. It is possible to habituate an appropriate trunk posture, easily maintain muscle strength and muscle mass daily, and prevent the collapse of postures such as so-called straight neck.

[0035] By providing the belt-like holding member 11 that is wound from the waist toward the abdomen, the holding property of the pressing member 13 can be improved. By providing the holding member 11 with the positioning member 21 and the pressing member 23, the positioning of the pressing member 13 can be easily performed, and the pressure acting on the pressing member 13 can be appropriately set. By providing a plurality of pressing members 13 arranged on both sides in the left-right direction with respect to the spine SP, a force F in the direction penetrating between the fifth lumbar vertebra L5 and the second sacral vertebra S2 can be appropriately generated. By providing the pressing member 13 with the flat surface 13B that contacts the holding member 11, the direction in which the curved surface 13A of the pressing member 13 is pressed against the waist of the human body can be easily regulated as desired.

[0036] (Modification example) Hereinafter, a modification example of the embodiment will be described. For the same parts as those in the above-described embodiment, the same reference numerals are given and the description is omitted or simplified. In the above-described embodiment, it is assumed that the abdominal pressure is increased by the holding member 11, but it is not limited thereto. For example, at least one abdominal side pressing member 31 held by the holding member 11 may be provided. In the above-described embodiment, the holding member 11 is assumed to apply pressure to the body to which it is attached, but it is not limited thereto. For example, a pressure dispersion member 33 held by the holding member 11 between the waist and the abdomen may be provided. In the above-described embodiment, two pressing members 13 having the vertical position H(L4 - S2) between the fourth lumbar vertebra L4 and the second sacral vertebra S2 of the spine SP as the action point P are provided, but the present invention is not limited thereto. For example, an upper-side holding member 41 and at least one upper-side pressing member 43 disposed above the holding member 11 and each pressing member 13 may be provided.

[0037] FIG. 8 is a diagram showing the positions of the two pressing members 13 and the two upper-side pressing members 43 in a state where the trunk wearing device 10A according to the first modification of the embodiment is worn on the human body HB. FIG. 9 is a cross-sectional view showing a state where the trunk wearing device 10A according to the first modification of the embodiment is worn on the human body HB. FIG. 10 is a diagram showing the vertical positions H(L4 - S2), H(L1 - L3) of the action points P, PU of the pressing member 13 and the upper-side pressing member 43, and the positions of the abdominal-side pressing member 31 and the upper-abdominal-side pressing member 45 in a state where the trunk wearing device 10A according to the first modification of the embodiment is worn on the human body HB.

[0038] As shown in FIGS. 8, 9, and 10, the trunk wearing device 10A according to the first modification of the embodiment includes, in addition to the holding member 11 and the two pressing members 13 of the above-described embodiment, an abdominal-side pressing member 31, two pressure dispersing members 33, an upper-side holding member 41, two upper-side pressing members 43, and an upper-abdominal-side pressing member 45.

[0039] The outer shape of the abdominal side pressing member 31 is, for example, a rectangular plate shape having flat surfaces on both sides (inner and outer surfaces). The abdominal side pressing member 31 is formed of a hard material such as resin or metal, for example. The abdominal side pressing member 31 is accommodated in the abdominal side member holding portion 21b of the positioning member 21 such that, for example, the flat surfaces face the human body side and the inside of the positioning member 21 while the thickness direction is parallel to the front-rear direction of the human body. The abdominal side member holding portion 21b is provided on, for example, at least one of the inner surfaces (the surface on the human body side) at both ends in the longitudinal direction of the positioning member 21. The outer shape of the abdominal side member holding portion 21b is, for example, a bag shape with an open upper side. The abdominal side pressing member 31 generates a force F1 in the direction along the front-rear direction of the human body HB by pressing the flat inner surface 31A against the abdomen of the human body by the pressure acting from the holding member 11, for example. The force F1 acting on the abdomen from the abdominal side pressing member 31 increases the abdominal pressure and generates a force FS that supports the fulcrum Q of the anterior superior iliac spine, for example.

[0040] The outer shape of the pressure dispersion member 33 is, for example, a rectangular plate shape. The pressure dispersion member 33 is formed of a flexible material such as soft foam polyurethane or gel-like silicone, for example. The pressure dispersion member 33 is accommodated in the side member holding portion 21c on the side portion of the positioning member 21. The side member holding portion 21c on the side portion is provided on the inner surface (the surface on the human body side) between the two member holding portions 21a and the abdominal side member holding portion 21b in the longitudinal direction of the positioning member 21. The outer shape of the side member holding portion 21c on the side portion is, for example, a bag shape with an open upper side. The pressure dispersion member 33 disperses the pressure acting from the holding member 11 so as to prevent the holding member 11 from digging into the side portion between the waist and abdomen of the human body, for example.

[0041] The upper side holding member 41 includes, for example, an upper side positioning member 51 and two upper side pressing members 53. The outer shape of the upper side holding member 41 is substantially the same as the outer shape of the holding member 11 in the above-described embodiment, and the upper side holding member 41 is formed of substantially the same material as the holding member 11 in the above-described embodiment. The outer shapes of the upper positioning member 51 and the upper pressing member 53 are, for example, strip-shaped or belt-shaped with a wide string shape. Each of the upper positioning member 51 and the upper pressing member 53 is formed of an elastic material such as rubber and resin, for example, and thus has stretchability and pressure-applying properties.

[0042] For example, the length of the upper positioning member 51 in the longitudinal direction is formed to be at least the length required to be wound around the body of the human body to form a ring shape. The positioning member 21 is provided with detachable coupling members such as hook-and-loop fasteners on both surfaces (inner surface and outer surface) of a predetermined portion such as both ends in the longitudinal direction, for example. The upper positioning member 51 is wound around from the waist to the abdomen of the human body, for example, and both ends in the longitudinal direction are overlapped in the thickness direction on the abdomen side, and the coupling members provided at the predetermined portions are coupled to each other, so that the upper positioning member 51 is annularly attached to the body of the human body.

[0043] The upper positioning member 51 is provided with two upper member holding portions (not shown) for holding two upper pressing members 43 at the central portion in the longitudinal direction, for example. The two upper member holding portions are provided on the inner surface (the surface on the human body side) at a predetermined interval in the longitudinal direction of the upper positioning member 51, for example. The outer shape of each upper member holding portion is, for example, a bag shape with an opening on the upper side. The upper positioning member 51 is provided with an upper abdomen pressing member holding portion (not shown) for holding the upper abdomen pressing member 45 on at least one of the inner surfaces (the surface on the human body side) at both ends in the longitudinal direction, for example. The outer shape of the upper abdomen pressing member holding portion is, for example, a bag shape with an opening on the upper side.

[0044] For example, the length of each upper pressing member 53 in the longitudinal direction is formed to be shorter than the circumference of the body when the body is tightened. Among the first end portion and the second end portion which are both end portions in the longitudinal direction of each upper pressing member 53, the first end portion is fixed to the central portion in the longitudinal direction of the upper positioning member 51. Each upper pressing member 53 is provided with a coupling member that is detachable from the upper positioning member 51 such as a hook-and-loop fastener on the inner surface (the surface on the human body side) of a predetermined portion such as the second end portion, for example.

[0045] The outer shapes of the upper-side pressing member 43 and the upper-abdomen-side pressing member 45 are, for example, rectangular plate-shaped with flat surfaces on both sides (inner and outer surfaces). The upper-side pressing member 43 and the upper-abdomen-side pressing member 45 are formed of a hard material such as resin or metal, for example. The upper-side pressing member 43 and the upper-abdomen-side pressing member 45 are accommodated in the upper-side member holding portion and the upper-abdomen-side member holding portion such that, for example, while the thickness direction is parallel to the front-rear direction of the human body, the flat surfaces face the inside of the human-body-side and upper-side positioning member 51. The upper-side pressing member 43 and the upper-abdomen-side pressing member 45 are, for example, pressed against the waist and abdomen of the human body by the pressure acting from the upper-side holding member 41, with the flat inner surfaces 43A and 45A.

[0046] The flat inner surfaces 43A of the two upper-side pressing members 43 are, for example, pressed against the rear-side apex portions A of the left and right erector spinae muscles. Each upper-side pressing member 43 has, for example, the vertical position H (L1 - L3) between the first lumbar vertebra L1 and the third lumbar vertebra L3 of the spine SP of the human body HB as the action point PU. Each upper-side pressing member 43 generates, for example, a force FU in the direction along the front-rear direction of the human body HB. The upper-abdomen-side pressing member 45 is, for example, pressed against the abdomen of the human body by the pressure acting from the upper-side holding member 41, with the flat inner surface 45A, and generates a force F2 in the direction along the front-rear direction of the human body HB.

[0047] The force FU acting on the spine SP from the two upper-side pressing members 43 and the force F2 acting on the abdomen from the upper-abdomen-side pressing member 45 increase the abdominal pressure by sandwiching the lumbar vertebra from the front and back, and generate a force FL acting on the lumbar vertebra. The force FL acting on the lumbar vertebra promotes an appropriate degree of forward bending of the lumbar vertebra, and suppresses, for example, a state in which the pelvis PV tilts forward and the lumbar vertebra bends forward excessively, that is, the occurrence of an excessive curvature posture.

[0048] According to the above-described first modification example, by providing the abdominal side pressing member 31, the direction of the abdominal pressure can be set as desired, and by sandwiching the lumbar vertebra from the front and back together with the pressing member 13 on the lumbar side, an appropriate degree of forward bending of the lumbar vertebra can be promoted. For example, it is possible to suppress the occurrence of a state in which the pelvis PV tilts forward and the lumbar vertebra bends forward excessively, that is, an excessive curvature posture. By providing the pressure dispersion member 33, the pressure acting from the holding member 11 can be dispersed so as to suppress the holding member 11 from biting into the side portion between the lumbar region and the abdominal region of the human body. By providing the upper side holding member 41, the two upper side pressing members 43, and the upper abdominal side pressing member 45, by sandwiching the lumbar vertebra from the front and back, an appropriate degree of forward bending of the lumbar vertebra can be promoted. For example, it is possible to suppress the occurrence of a state in which the pelvis PV tilts forward and the lumbar vertebra bends forward excessively, that is, an excessive curvature posture.

[0049] In the above-described embodiment and the first modification example, at least any one of the pressing member 13, the abdominal side pressing member 31, the pressure dispersion member 33, the upper side pressing member 43, and the upper abdominal side pressing member 45 may be integrally held with the holding member 11 or the upper side holding member 41, or may be removably or replaceably held. In the above-described first modification example, it is assumed that each one abdominal side pressing member 31 and upper abdominal side pressing member 45 are provided, but the present invention is not limited thereto, and a plurality of each abdominal side pressing member 31 and upper abdominal side pressing member 45 may be provided. In the above-described first modification example, the outer shapes of the abdominal side pressing member 31, the upper side pressing member 43, and the upper abdominal side pressing member 45 are each in a flat plate shape, but the present invention is not limited thereto, and for example, a curved plate shape or the like may be used.

[0050] In the above-described embodiment and the first modification example, the body trunk wearables 10, 10A are provided with two pressing members 13, but the present invention is not limited thereto, and it is sufficient to be provided with at least one pressing member 13. In the first modification described above, the trunk wearing device 10A is provided with two upper pressing members 43, but the present invention is not limited to this, and it may be provided with at least one upper pressing member 43.
