Description

FIELD OF THE DISCLOSURE The present disclosure relates to pressure devices used to restrict blood flow in an exerciser during strength training.

As an example of strength training, a method is known in which the body part to be trained is compressed to restrict the blood flow mainly in the capillaries in the muscle, and to apply a load to the hypoxic muscle. there is According to this strength training, the activity of the slow-twitch fibers can be slowed down while the activity of the fast-twitch fibers can be activated by restricting the blood flow. It becomes possible. Hereinafter, such strength training is also referred to as "blood flow restriction training" in this specification.

Blood flow restriction training may use a band-like compression device, also called a "cuff," that is wrapped around the body part of the exerciser to restrict blood flow. In such pressurizing devices, gas such as air is normally supplied to the belt-shaped member from a pressurizing pump placed at a position away from the exerciser through a flexible piping member such as a tube. It has a configuration in which an expanding pressurizing portion is provided. For example, Patent Literature 1 below discloses a cuff having a structure in which a rubber tube is inserted into a fabric tube.

In order to more reliably restrict blood flow and increase training effects, it is desirable that the pressurization device described above can pressurize a wide range of body parts to be trained, such as the upper arms and thighs of the exerciser. . Moreover, it is desirable that the gas can be smoothly supplied to the pressurizing portion during pressurization. However, for example, in order to expand the pressurization range, when the pressurization device is configured by a plurality of elongated cloth tubes wound in parallel around the body part of the exerciser, In some cases, the branched cloth tubes become entangled, making it difficult to handle them. Moreover, in such a configuration, if a situation arises in which some of the fabric tubes are not properly wound around the body part of the exerciser, the supply of pressurized air to the part of the fabric tubes is not properly performed. In some cases, it was lost.

Means the average value of the opening area on the surface where The “channel width Wa” of the gas channel 21 is the average value of the dimensions of the gas channel 21 in the direction perpendicular to the central axis of the gas channel 21 and along the surface of the belt-shaped member 11 . Due to the configuration in which the gas flow path 21 closer to the first width end portion 13a has a smaller flow path area, the belt-shaped member 11 is wound around the body part of the exerciser, and when the pressurizing portion 12 is filled with gas, the belt-shaped member 11 is wound. The member 11 can be brought into closer contact with the exerciser's body part. Therefore, more effective blood flow restriction is possible.

In this embodiment, the width of each channel wall 22 is substantially the same. The width of the channel wall 22 means the average value of the dimensions in the direction perpendicular to the central axis of each channel wall and along the surface of the belt-shaped member 11 . Note that in other embodiments, the width of each channel wall 22 may be different. In the pressurizing section 12 , the width of the channel wall 22 may be made larger than the width of the other channel walls 22 at the portion where swelling is desired to be suppressed when filled with gas. For example, the width of the channel wall 22 provided in the central portion in the width direction may be larger than the width of the channel wall 22 arranged on the outermost side in the width direction. As a result, when the pressurizing portion 12 is filled with gas, it is possible to prevent the central portion of the pressurizing portion 12 from expanding excessively in the width direction.

Please refer to FIG. In this embodiment, the pressurizing portion 12 is provided with the pipe connection portion 25 in the center region of the strip member 11 in the width direction. As a result, the gas supplied from the pipe connection portion 25 flows through the gas flow path 21 on the first width end portion 13a side with respect to the pipe connection portion 25 and the second width end portion 13b side with respect to the pipe connection portion 25 . , and the gas flow path 21 located at . Therefore, it is suppressed that the pressurizing portion 12 is biasedly swollen due to unevenly flowing in either the first width end portion 13a side or the second width end portion 13b side.

As described above, in the present embodiment, the first communication paths 23a and the second communication paths 23b having different channel cross-sectional areas are arranged alternately in the width direction. As a result, most of the gas sent to the pressurizing portion 12 through the pipe connection portion 25 flows from the pipe connection portion 25 to the gas flow path 21 as indicated by the arrow FL, and then turns back at the first communication passage 23a to flow into the adjacent gas passage 23a. is guided to flow into the gas flow path 21 of the Thus, it is interpreted that the internal space 20 of the pressurizing part 12 is partitioned into a channel-shaped space in which the return channels that are folded back so as to reciprocate in the longitudinal direction of the strip-shaped member 11 are arranged in the width direction of the strip-shaped member 11. can. With a channel configuration that allows such a flow of gas, the gas channels 21 can be expanded in order, and the gas can be spread smoothly over the entire pressurizing section 12 .

Further, in this embodiment, a second communication path 23b is provided in addition to the first communication path 23a. As a result, in addition to the gas path indicated by the arrow FL described above, a gas path via the second communication path 23b is formed. can. Further, even if the gas flow is blocked in the first communication path 23a corresponding to the folded portion of the adjacent gas flow path 21, the gas can flow into the adjacent gas flow path 21 through the second communication path 23b. . Therefore, it is possible to prevent the gas from flowing into each gas flow path 21 unevenly.

In addition, the provision of the second communication path 23b allows the gas in each gas flow path 21 to quickly flow to the pipe connection part 25 when the exerciser removes gas from the pressurizing part 12 after training. can be drained to Therefore, the discharge of gas from the pressurizing part 12 is facilitated, and the labor and time required for discharging the gas from the pressurizing part 12 can be reduced.

In the configuration of the first embodiment, it is desirable that the cross-sectional area of the first communication path 23a corresponding to the folded portion of the gas flow path 21 is smaller than the cross-sectional area of the other portions of the gas flow path 21. . As a result, it is possible to prevent the pressure effect of the central region of the pressure member 12 on the body part of the exerciser from being reduced due to the large expansion of both ends of the pressure member 12 in the longitudinal direction of the belt-shaped member 11 .

FIG. 5 is a schematic cross-sectional view of the belt-shaped member 11 taken along line 5-5 shown in FIG. The belt-shaped member 11 is constructed by overlapping a first base material 30a forming the outer surface Sa and a second base material 30b forming the body side surface Sb. The first base material 30a and the second base material 30b are made of a stretchable material. The first base material 30a and the second base material 30b are made of, for example, a resin material such as chloroprene rubber. The first base material 30a and the second base material 30b may be made of a fibrous material such as cloth.

In this embodiment, the first base material 30a is configured to be more difficult to expand and contract than the second base material 30b. In this embodiment, the first base material 30a is made of a material that is less stretchable than the second base material 30b. Since the first base member 30a is configured to be more difficult to expand and contract than the second base member 30b, the pressure member 12 is suppressed from expanding toward the first base member 30a, and the pressure member 12 is stretched by the exerciser's body. Reduction in the pressure applied to the site is suppressed. In another embodiment, the stretchability of the first base material 30a is made lower than that of the second base material 30b by attaching a member that is less stretchable than the second base material 30b to the surface of the first base material 30a. good too. The hard-to-stretch base material attached to the first base material 30a may be, for example, a first hook-and-loop fastener 37a, which will be described later.

The bag-like member 32 that constitutes the pressure member 12 has a first surface portion 33 that faces the body part of the exerciser around which the belt-like member 11 is wound, and a side that is opposite to the first surface portion 33 with the inner space 20 interposed therebetween. and a second surface portion 34 disposed on the . A channel wall 22 that partitions the gas channel 21 in the internal space 20 of the pressurizing unit 12 is formed by thermally welding the first surface portion 33 and the second surface portion 34 together.

In this embodiment, the first surface portion 33 is configured to be more flexible than the second surface portion 34 . In the present embodiment, the first surface portion 33 has a single-layer structure and the second surface portion 34 has a multi-layer structure with a difference in thickness, so that the first surface portion 33 is easier to bend than the second surface portion 34. . As a result, when the bag-like member 32 is filled with gas, the bag-like member 32 easily expands toward the first surface portion 33 arranged on the body side of the exerciser.

In another embodiment, the first surface portion 33 also has a multi-layer structure, and the second surface portion 34 has a multi-layer structure having more layers than the first surface portion 33. It may be configured to be more flexible than the second surface portion 34 . Further, by changing the types of the constituent materials of the first surface portion 33 and the second surface portion 34, or by changing the thicknesses of the first surface portion 33 and the second surface portion 34, the first surface portion 33 can be changed to the second surface portion. It may be configured to be more flexible than 34 .

As described above, the belt-shaped member 11 of the present embodiment is configured such that when the pressurizing portion 12 is filled with gas, the side surface Sb of the body is more easily inflated than the outer surface Sa opposite to the side surface Sb of the body. . As a result, when the pressurizing portion 12 is filled with gas, the body side surface Sb of the belt-shaped member 11 can be expanded more than the outer surface Sa. Therefore, the effect of pressing the body part of the exerciser by the pressurizing device 10 can be enhanced. Note that the belt-shaped member 11 may be configured so that the body side surface Sb is more flexible than the outer side surface Sa over the entire longitudinal direction.

A method of winding the belt-shaped member 11 around the exerciser's body will be described with reference to FIG. The state of the winding process of the belt-like member 11 is schematically illustrated in order in the left column of FIG. 6, the center column of the page, and the right column of the page. First, in the first step shown in the left column of the paper surface of FIG. 6, the first band end portion 13c side of the band-shaped member 11 is wound around the front side of the thigh of the exerciser, and the front side of the thigh is pressed. A part 12 is arranged.

Next, in the second step shown in the center column of the paper surface of FIG. It is wound onto the pressure portion 12 . At this time, the second hook-and-loop fasteners 37b provided on the body side surfaces Sb of the first portion 14a and the second portion 14b are adhered to the first hook-and-loop fasteners 37a on the outer side surface Sa. As a result, the pressurizing part 12 is fixed to the body part to restrict the blood flow. According to the belt-shaped member 11 of the present embodiment, since the first portion 14a and the second portion 14b are separated from each other, the first portion 14a and the second portion 14b are separated when wrapped around the body of the exerciser. The mutual spacing in the width direction can be adjusted. Therefore, it is easy to fix the pressurizing part 12 in a state that fits the body shape of the exerciser.

Furthermore, in the third step shown in the right column of the paper surface of FIG. 6, the belt-shaped member 11 wound around the body of the exerciser is further fastened by the fastening belt portion 18 . Specifically, while pulling and extending the first V-shaped belt 18a of the fastening belt portion 18 toward the second belt end portion 13d, the third hook-and-loop fastener 37c at the tip portion BE is attached to the outer surface of the first portion 14a. It is adhered to the first hook-and-loop fastener 37a of Sa. Further, while pulling and extending the second V-shaped belt 18b of the fastening belt portion 18 to the rear side of the thigh, the third hook-and-loop fastener 37c of the tip portion BE is attached to the first surface of the outer surface Sa of the belt-shaped member 11. It is adhered to the fastener 37a. As a result, fastening force can be applied to the pressure member 12 from above the belt-like member 11 by the two V-shaped belts 18a and 18b. Therefore, fixability to the exerciser's body part is enhanced. In addition, the effect of compressing the body part of the exerciser by the pressurizing part 12 is enhanced, and it becomes possible to restrict the blood flow more reliably. In addition, in this embodiment, the two V-shaped belts 18a and 18b have a shape folded back in a V-shape so as to form a slit portion SL. As a result, by routing the two V-shaped belts 18a and 18b, an effect equivalent to fastening the belt-like member 11 with four belts can be obtained.

As described above, according to the pressurizing device 10, by simply winding the single belt-shaped member 11 around the body of the exerciser, a plurality of parallel belt-shaped members arranged in the width direction of the belt-shaped member 11 constitute the pressure unit 12. A gas channel 21 can be arranged. Therefore, it is possible to easily achieve a wide pressurization range similar to winding a plurality of cuffs around the body of an exerciser in parallel. As a result, even if the exerciser moves vigorously, the expansion of blood vessels can be suppressed over a wide range, and the blood flow can be effectively restricted. In addition, since the plurality of gas flow paths 21 communicate with each other through the two communication paths 23a and 23b, it is easy to spread the gas smoothly over the entire pressurizing section 12 at the start of pressurization. can be Therefore, uneven pressurization by the pressurizing unit 12 due to inability of the gas to flow into a partial area of the pressurizing unit 12 is suppressed.

7A and 7B are schematic diagrams showing the configuration of the piping member 15. FIG. FIG. 7A illustrates a state in which the piping member 15 is contracted with no external force applied thereto, and FIG. 7B illustrates a state in which the piping member 15 is expanded by applying an external force.

The piping member 15 has a coil portion 40 formed so as to retain the shape of the tube 16 wound spirally, and linear portions 41 and 42 provided at both ends of the coil portion 40 . The tube 16 is made of, for example, a resin material such as polyurethane, and has a diameter of, for example, approximately 3 to 10 mm. The tube 16 has, for example, pressure resistance of about 0 to 400 millimeters of mercury (mmHg), that is, pressure resistance of about 0 to 53.3 kPa.

The length of the coil portion 40 is, for example, about 500 mm to 2000 mm in a contracted state without being stretched. The diameter of the coil portion 40 is about 3 to 5 times the diameter of the tube 16, for example, about 20 to 40 mm. The coil portion 40 has flexibility and can be freely bent and stretched. Also, the coil portion 40 is elastically deformed. The coil portion 40 extends when a tensile external force along the central axis of the spiral is applied, and contracts when the external force is released. When an external force is applied in the direction of the central axis, the coil portion 40 expands, for example, to a length of 3 to 5 times or more.

The first linear portion 41 and the second linear portion 42 are portions formed so that the tube 16 retains its linear shape. The first linear portion 41 is connected to the pipe connection portion 25 of the belt-shaped member 11 . The second linear portion 42 is connected to the control unit 50 . In this embodiment, the length La of the first linear portion 41 is longer than the length Lb of the second linear portion 42 . Since the first linear portion 41 is long, the coil portion 40 can be separated from the belt-shaped member 11 . Therefore, it is possible to suppress the coil portion 40 from becoming an obstacle when the belt-shaped member 11 is wound around the body of the exerciser, and it is possible to suppress the tangling of the piping member 15 . On the other hand, since the second linear portion 42 is short, the second linear portion 42 can be bent even when the piping member 15 is largely moved relative to the control unit 50 during training of the exerciser. can be suppressed, and the occurrence of gas supply failure to the pressurizing portion 12 due to blockage of the second linear portion 42 can be suppressed. In other embodiments, the length La of the first linear portion 41 and the length Lb of the second linear portion 42 may be equal. Alternatively, the second linear portion 42 may be omitted.

According to the piping member 15, the coil portion 40 forming the main body portion is flexible like a spring and expands and contracts. In addition, since the coil portion 40 is elastically deformed, it easily returns to its original shape. Therefore, the occurrence of entanglement during exercise by the exerciser is further suppressed. Furthermore, according to the piping member 15 , the diameter of the coil portion 40 is larger than the diameter of the tube 16 forming the coil portion 40 . Therefore, handling of the piping member 15 is easier than in the case where the piping member 15 is composed of the tube 16 that is not formed into a coil shape. In addition, since the piping member 15 is prevented from getting caught in narrow gaps of the exercise equipment used by the exerciser, the piping member 15 is prevented from becoming entangled with the exercise equipment used by the exerciser.

According to the piping member 15, even if the load applied to the piping member 15 when the exerciser moves violently is dispersed by the bending deformation of the coil portion 40, the load is locally applied to the tube 16, and the tube 16 is suppressed from bending. Therefore, the gas can be stably and smoothly supplied to the pressurizing unit 12 even during the exerciser's training.

Further, according to the piping member 15, since the path of the gas from the pressure pump 53 to the pressurizing unit 12 is lengthened by the length of the spirally wound tube 16, the amount of gas being drawn is increasing. If the amount of gas in the piping member 15 increases, the piping member 15 can absorb and mitigate sudden pressure fluctuations in the pressurizing section 12 caused by the movement of the exerciser. Therefore, it is possible to prevent the control section 55 of the control unit 50 from reacting excessively to such rapid pressure fluctuations in the pressurizing section 12 and the control of the pressurizing pump 53 by the control section 55 becoming unstable. Therefore, it is possible to suppress unstable pressurization of the body part of the exerciser by the pressurizing unit 12 .

In addition, according to the piping member 15, by hooking a mooring portion such as a hook between the annular portions 43 formed by the tube 16 in the coil portion 40, an arbitrary portion in the middle of the piping member 15 can be attached to the mooring portion. can be moored to Therefore, the movement range of the piping member 15 can be easily restricted.

As described above, according to the pressurizing device 10 of the present embodiment, the piping member 15 that connects the pressurizing pump 53 and the pressurizing section 12 is configured by a coil tube, so that the piping member 15 can be easily handled. , and entanglement of the piping member 15 is suppressed. Therefore, the occurrence of poor gas supply to the pressurizing unit 12 due to entanglement of the piping member 15 is suppressed.

2. Second embodiment:
FIG. 8 is a schematic diagram showing a training device 100A in the second embodiment. The training device 100A of the second embodiment has almost the same configuration as the training device 100 of the first embodiment, except that the configuration of the belt-shaped members 11A of the pressurizing devices 10Aa and 10Ab is different.

The belt-like member 11A in the unfolded state has a configuration in which two belt-like belt portions 61 and 62 extend in opposite directions in the longitudinal direction from a substantially rectangular central belt portion 60 . As will be described later, the belt-shaped member 11A as a whole has a shape slightly curved in the longitudinal direction.

The central belt portion 60 has a bag-like configuration in which substantially rectangular belt-like members forming the outer surface Sa and the body side surface Sb are superimposed and joined at the outer peripheral edges. Most of the outer surface Sa of the central belt portion 60 is covered with a first hook-and-loop fastener 37a composed of a comfortable loop. The body side surface Sb of the central belt portion 60 is made of, for example, a plate-like rubber member. As a result, it is possible to prevent the central belt portion 60 from slipping on the body part of the exerciser.

Inside the central belt portion 60, the pressure portion 12A is accommodated. The pressurizing portion 12A is arranged over substantially the entire inside of the central belt portion 60. As shown in FIG. The pressurizing part 12A of the second embodiment differs from the pressurizing part 12 of the first embodiment in the flow passage configuration of the internal space 20. As shown in FIG. The details of the configuration of the pressurizing section 12A will be described later.

A pipe connection portion 25 that connects the internal space 20 of the pressurizing portion 12A and the pipe member 15 is provided in the central portion of the outer surface Sa of the central belt portion 60 . In addition, the piping member 15 is configured by the same coil tube as described in the first embodiment. The internal space 20 of the pressurizing section 12A is connected via a piping member 15 to a control unit 50 having the same configuration as described in the first embodiment.

The first belt portion 61 and the second belt portion 62 are arranged on the outer surface Sa of the central belt portion 60, that is, on the pressing portion 12A, at positions offset from each other in the width direction of the belt-like member 11A. The first belt portion 61 is arranged on the first width end portion 13a side of the central belt portion 60, and the second belt portion 62 is arranged on the second width end portion 13b side of the central belt portion 60. As shown in FIG. The first belt portion 61 and the second belt portion 62 extend longitudinally in opposite directions from the center of the arrangement area of the pressing portion 12A. As will be described later, the first belt portion 61 and the second belt portion 62 are wound around the body part of the exerciser in opposite directions.

Base end portions BB of the first belt portion 61 and the second belt portion 62 are sewn and fixed to the outer surface Sa of the central band portion 60 . Moreover, a rectangular frame-shaped fastener 65 functioning as a buckle is provided at each of the base ends BB of the first belt portion 61 and the second belt portion 62 . As will be described later, each of the belt portions 61 and 62 is folded back at its own fastener 65 when the belt-shaped member 11A is rolled into a cylinder.

The first belt portion 61 and the second belt portion 62 have a first belt surface BSa and a second belt surface BSb on the back side thereof. The first belt surface BSa is a surface arranged on the same side as the outer surface Sa of the central belt portion 60 when the belt-shaped member 11A is deployed. The second belt surface BSb is a surface arranged on the same side as the body side surface Sb of the central belt portion 60 when the belt-shaped member 11A is deployed.

The first belt surfaces BSa of the first belt portion 61 and the second belt portion 62 are covered with the first hook-and-loop fastener 37a in most regions other than the tip portion BE. A second hook-and-loop fastener 37b is provided on the first belt surface BSa at the tip portion BE of the first belt portion 61 and the second belt portion 62 . The second hook-and-loop fastener 37b is composed of hooks corresponding to the loops of the first hook-and-loop fastener 37a.

In the second embodiment, the lengths of the first belt portion 61 and the second belt portion 62 are substantially the same, and are longer than the central band portion 60 by two times or more. The width of the first belt portion 61 and the second belt portion 62 is approximately half the width of the central band portion 60 . Note that in other embodiments, the first belt portion 61 and the second belt portion 62 may have different lengths and widths, or may have a width equal to or less than half the width of the central band portion 60 or It may have a width greater than half the width of the strip 60 .

In the second embodiment, the central belt portion 60 has a shape that is slightly arcuately curved in the width direction as a whole so that the first width end portion 13a side is slightly bulged in the width direction. In addition, the first belt portion 61 and the second belt portion 62 also have a slightly curved shape with the same curvature as the central belt portion 60 .

The base end BB side portions of the first belt portion 61 and the second belt portion 62 disposed on the central belt portion 60 are respectively the first width end portion 13a or the second width end portion of the central belt portion 60. 13b. As a result, the belt-shaped member 11A has a slightly curved shape in which the first width end 13a side swells over the entire longitudinal direction in the unfolded state. With this shape, the belt-like member 11A can be wound so as to be in closer contact with a body part such as the thigh of the exerciser.

FIG. 9 is a schematic exploded view of the strip member 11A. In FIG. 9, the pressurizing portion 12A and the reinforcing plate 68 housed inside the central belt portion 60 are shown separately.

In the vicinity of the first width end portion 13a of the central belt portion 60, an outlet 19 configured as a linear cut extending in the longitudinal direction along the first width end portion 13a is provided. The pressurizing portion 12A and the reinforcing plate 68 are detachably accommodated inside the central belt portion 60 via the outlet 19. As shown in FIG. The outlet 19 may be provided with a fastener for opening and closing.

The pressurizing portion 12A is configured by an airtight bag-like member 32 having a substantially rectangular shape. The bag-shaped member 32 is airtightly configured by a resin film member such as polyurethane. In the second embodiment, the bag-shaped member 32 constituting the pressure member 12A is designed so that the strength of the first surface portion 33 on the side of the body side Sb and the strength of the second surface portion 34 on the side of the outer surface Sa do not differ. , the first surface portion 33 and the second surface portion 34 are each composed of a single layer having the same thickness.

A connection pipe 27 constituting a pipe connection portion 25 is provided at the central portion in the width direction and the longitudinal direction of the pressurizing portion 12A. The connecting pipe 27 is connected to the end of the piping member 15 and communicates with the internal space 20 . When the pressurizing portion 12A is housed in the central band portion 60, the connecting pipe 27 protrudes from the center of the central band portion 60 to the outside so as to be connectable to the piping member 15. As shown in FIG.

A cover member 28 that covers the connecting pipe 27 is attached to the central belt portion 60 . The cover member 28 is made of, for example, a resin member such as silicone rubber or polypropylene. The cover member 28 constitutes the pipe connection portion 25 together with the connection pipe 27 . The cover member 28 has a semi-cylindrical portion, and the connecting pipe 27 protruding from the inside of the central belt portion 60 is fitted to the inner peripheral surface of the semi-cylindrical portion of the cover member 28 . A connecting portion between the connecting pipe 27 and the piping member 15 is covered and protected by the semi-cylindrical portion of the cover member 28 .

The internal space of the bag-shaped member 32 is partitioned into a plurality of parallel gas flow paths 21 along the longitudinal direction. The plurality of gas flow paths 21 are arranged in parallel in the width direction. The channel wall 22 that partitions the gas channel 21 is formed by heat-welding the resin film members forming the first surface portion 33 and the second surface portion 34 of the bag-like member 32 .

In the second embodiment, each gas flow path 21 includes a central communication passage 23c provided in the central portion in the longitudinal direction of the internal space 20, and end communication passages 23e provided at both ends in the longitudinal direction of the internal space 20. and are in communication with each other. The connecting pipe 27 described above is provided at the central position of the central communication passage 23c.

According to the flow path configuration of the gas flow paths 21 in the pressurizing section 12A of the second embodiment, the gas introduced from the connection pipe 27 can be smoothly distributed to the respective gas flow paths 21 through the central communication path 23c. can. In addition, since each gas flow path 21 communicates with each other through the end communication path 23e, the gas can be smoothly distributed to every corner of the internal space 20 of the pressurizing section 12A.

In the pressurizing section 12A of the second embodiment, the channel width of the gas channel 21 differs depending on the position where it is formed. In the pressurizing section 12A, the flow path width of the gas flow path 21 is changed for each section in the pressurizing section 12A so as to suppress the occurrence of a section that expands less than other sections when the gas is filled. It is

In the second embodiment, two regions adjacent to each other in the longitudinal direction with the central communication passage 23c interposed therebetween are configured asymmetrically. In the two regions, the width of the gas flow path 21 located under each of the belt portions 61 and 62 is larger than the width of the gas flow path 21 other than the belt portions 61 and 62 . This makes it easier for the gas to flow into the gas flow path 21 located under the base end BB side of the belts 61 and 62, and the base end BB side of the belts 61 and 62. It is suppressed that the lower area becomes difficult to swell.

In the belt-shaped member 11A of the second embodiment, the reinforcement plate 68 is housed inside the central belt portion 60, so that when gas is filled, the side of the body side Sb swells more than the side of the outer side Sa. is configured as The reinforcing plate 68 is made of a resin material, such as polypropylene, which has higher rigidity than the bag-shaped member 32 that forms the pressure member 12A.

The reinforcing plate 68 is arranged inside the central belt portion 60 so as to cover the surface of the pressing portion 12A on the side of the outer surface Sa. At the center of the reinforcing plate 68, a through hole 68h is provided through which the connecting pipe 27 of the pressurizing portion 12A is inserted.
