Moreover, each drawing does not specify the size relationship of the components of the pet absorbent article, and the dimensions of each component can be appropriately selected from a wide range depending on the purpose of the pet absorbent article, the type of pet to be used, and the like.

[0020] <Absorbent articles for pets> An absorbent article 10 for pets according to one embodiment of the present invention is to be worn by pets (for example, dogs, cats, etc.), and is particularly suitable for use with male pets.

[0021] 1 and 2, the pet absorbent article 10 of this embodiment includes a liquid-permeable top sheet 11 on the skin side, a liquid-impermeable back sheet 12 on the non-skin side, an absorbent body 13, front and rear three-dimensional gathers 14, a mechanical hook tape (fastening part) 15, and left and right leg belts 16, and is formed long in a first direction (X direction in the figure, hereinafter referred to as "longitudinal direction"). Note that, in this embodiment, the shape of the pet absorbent article 10 is substantially rectangular, but is not limited thereto, and the shape of the pet absorbent article 10 may be at least a belt-like shape that can be worn around the pet's waist.

[0022] The length L of the pet absorbent article 10 in the longitudinal direction is preferably 300 mm or more and 570 mm or less. The length W of the pet absorbent article 10 in the second direction (Y direction in the figure, hereinafter referred to as the "width direction") is preferably 180 mm or more and 350 mm or less. By setting the dimensions of the pet absorbent article 10 within the above ranges, a pet absorbent article 10 of a size suitable for pets such as dogs and cats can be obtained. Furthermore, by setting the dimensions of the pet absorbent article 10 within the above ranges, a pet absorbent article 10 that can also be used for pets (e.g., dogs) with a large (thick) waist circumference and a short torso length can be obtained.

[0023] (Top sheet) The top sheet 11 may be formed from a substrate having liquid permeability that allows bodily fluids to move to the absorbent 13. Examples of substrates for the top sheet 11 include hydrophilic sheets, composite nonwoven fabrics that are laminates of the same or different hydrophilic sheets, open-ended films such as open-ended polyethylene films, and foamed films such as polyethylene foams and urethane foams. Examples of hydrophilic sheets include air-through nonwoven fabrics, thermal bond nonwoven fabrics, spunlace nonwoven fabrics, and spunbond nonwoven fabrics made from synthetic fibers made of synthetic resins such as polypropylene and polyethylene, regenerated fibers such as rayon, and natural fibers such as cotton. Among these, nonwoven fabrics are preferred, and air-through nonwoven fabrics or spunbond nonwoven fabrics are more preferred from the viewpoint of texture.

[0024] The top sheet 11 may be embossed or perforated on its surface to improve liquid permeability. Any known method may be used for embossing or perforating the top sheet 11 without any restrictions. In addition, the top sheet 11 may contain lotion, antioxidant, anti-inflammatory component, pH adjuster, antibacterial agent, moisturizer, etc. to reduce irritation to the skin. The shape of the top sheet 11 is not particularly limited, and may be any shape that covers the absorbent body 13 to guide bodily fluids to the absorbent body 13 without leaking.

[0025] (Back seat) The back sheet 12 may be formed using a liquid-impermeable substrate so that the body fluid held by the absorbent 13 does not leak to the non-skin side, and is formed from a material such as a resin film or a composite sheet in which a resin film and a non-woven fabric are laminated. Among these, the back sheet 12 is preferably a composite sheet having a resin film (film portion) 17 on the skin side and a non-woven fabric (non-woven fabric portion) 18 located on the non-skin side of the resin film 17, as shown in FIG. 2, and laminated together. Note that FIG. 2 illustrates the back sheet 12 constituted by a composite sheet in which the resin film 17 and the non-woven fabric 18 are laminated, but the back sheet 12 is not limited thereto, and may be a back sheet 12 of a single resin film, or may be a back sheet 12 constituted by a composite sheet in which three or more layers are laminated together.

[0026] Examples of the resin film 17 used in the back sheet 12, which is a composite sheet, include polyester, polyvinyl alcohol, polyethylene, polypropylene, and composite films of polyethylene and polypropylene.

[0027] The nonwoven fabric 18 used in the back sheet 12, which is a composite sheet, is not particularly limited in its manufacturing method, and examples thereof include composite nonwoven fabrics obtained by laminating multiple identical and / or different types of nonwoven fabrics, such as spunbond nonwoven fabric, meltblown nonwoven fabric, spunbond nonwoven fabric / meltblown nonwoven fabric, and spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric, and composite materials thereof.

[0028] It is preferable that the back sheet 12 has breathability to prevent stuffiness during wear. In order to provide the back sheet 12 with breathability, for example, a filler may be blended into the resin film 17 of the base material, or the back sheet 12 may be embossed. An example of the filler is calcium carbonate, and the blending method may be any known method without limitation. For example, a porous (breathable) resin film can be obtained by kneading a resin and a filler, forming the resulting kneaded product into a film, and removing the filler from the resulting film.

[0029] (Absorbent) The absorbent body 13 is disposed between the top sheet 11 and the back sheet 12, and absorbs and retains bodily fluids that have permeated through the top sheet 11. The shape of the absorbent body 13 is not particularly limited, and examples thereof include a rectangular shape, an oval shape, and the like.

[0030] The absorbent body 13 may contain, for example, absorbent fibers and a highly water-absorbent polymer as an absorbent base material.

[0031] (Absorbent Fiber) The absorbent fiber is not particularly limited as long as it is generally used in absorbent articles such as sanitary napkins, paper diapers, and urine pads, and examples thereof include fluff pulp, cotton, rayon, acetate, tissue, absorbent paper, hydrophilic nonwoven fabric, etc. Among these, fluff pulp is preferred from the viewpoint of absorbency. Examples of fluff pulp include wood pulp (e.g., coniferous bleached kraft pulp (N-BKP) such as southern pine and Douglas fir), synthetic fiber, resin fiber, cotton-like defibrated material such as non-wood pulp, etc.

[0032] (Super absorbent polymer) The superabsorbent polymer (hereinafter also referred to as "SAP") is not particularly limited as long as it can absorb body fluids and prevent backflow, and examples thereof include polyacrylates, polyaspartates, (starch-acrylic acid) graft copolymers, (acrylic acid-vinyl alcohol) copolymers, (isobutylene-maleic anhydride) copolymers, and saponification products thereof. Among these, from the viewpoint of the absorption amount per weight, polyacrylates are preferred, polyacrylate alkali metal salts are more preferred, and sodium polyacrylate is even more preferred. The superabsorbent polymers can be used alone or in combination of two or more.

[0033] The superabsorbent polymer is used in the form of, for example, particles or fibers, and is preferably used in the form of particles from the viewpoint of ease of handling, etc. In this case, by avoiding the use of a fine powder of superabsorbent polymer that has poor flowability as a powder and using a superabsorbent polymer having a medium particle size, it is possible to improve basic absorption performance and reduce the rough feel caused by the absorbent body 13 becoming hard.

[0034] The absorbent fibers and SAP in the absorbent body 13 may be in the form of a mixture of SAP particles in absorbent fibers, or may be in the form of a SAP sheet with SAP particles fixed between absorbent fibers. Another form of absorbent body 13 may be an absorbent sheet including multiple hydrophilic nonwoven fabrics and a highly water-absorbent polymer fixed between the hydrophilic nonwoven fabrics.

[0035] (Absorbent paper) The entire absorbent 13 may be wrapped in absorbent paper (not shown). As the absorbent paper, any hydrophilic sheet commonly used in this field may be used, for example, hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabrics, spunbonded nonwoven fabrics, airlaid nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics, tissue paper, absorbent paper, etc. Among hydrophilic nonwoven fabrics, hydrophilic nonwoven fabrics such as thermal bonded nonwoven fabrics, spunbonded nonwoven fabrics, air-through nonwoven fabrics, and pulp-containing nonwoven fabrics are more preferred, and tissue paper (crepe paper), spunbonded nonwoven fabrics that have been subjected to hydrophilic treatment as necessary, and the like are even more preferred.

[0036] (Liquid diffusion sheet) A liquid-permeable liquid diffusion sheet (not shown) may be provided between the top sheet 11 and the absorbent 13. The liquid diffusion sheet diffuses bodily fluids from the top sheet 11 side and guides them to the absorbent 13 side. Examples of the liquid diffusion sheet include nonwoven fabrics such as air-through nonwoven fabrics, point-bonded nonwoven fabrics, spunbonded nonwoven fabrics, and melt-blown nonwoven fabrics, and composite nonwoven fabrics in which spunbond / melt-blown or spunbond / melt-blown / spunbond are laminated. The shape of the liquid diffusion sheet is not particularly limited, but it is preferable that the shape completely covers the surface of the absorbent 13 in order to thoroughly diffuse liquids such as urine into the absorbent 13, or that the shape does not cover the entire surface in order to reduce costs.

[0037] (Front and back gathers) The front and back three-dimensional gathers 14 are sheet-like members for preventing lateral leakage (leakage in the front-rear direction) of bodily fluids excreted by a pet wearing the pet absorbent article 10. The front and back three-dimensional gathers 14 are disposed on both sides in the width direction (Y direction) of the skin side of the top sheet 11, extend in the longitudinal direction, and are fixed to the top sheet 11. Note that the object to which the three-dimensional gathers 14 are fixed is not limited to the top sheet 11; for example, the three-dimensional gathers 14 may be fixed to the back sheet 12 in addition to the top sheet 11.

[0038] The sheet constituting the three-dimensional gathers 14 is a liquid-impermeable sheet having water-repellent and / or waterproof properties, and is made of, for example, a nonwoven fabric. As the nonwoven fabric, any water-repellent and / or waterproof (liquid-impermeable) nonwoven fabric made of hydrophobic fibers can be used without any particular limitation, and examples thereof include spunbond nonwoven fabric, meltblown nonwoven fabric, composite nonwoven fabric (SMS nonwoven fabric) which is a spunbond nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminate, and composite nonwoven fabric (SMMS nonwoven fabric) which is a spunbond nonwoven fabric / meltblown nonwoven fabric / meltblown nonwoven fabric / spunbond nonwoven fabric laminate. Among these, SMS nonwoven fabric is preferable.

[0039] Elastic stretchable members (not shown) may be provided on the front and back three-dimensional gathers 14. The elastic stretchable members may be arranged along the longitudinal direction of the front and back three-dimensional gathers 14 to impart standing ability to the front and back three-dimensional gathers 14. As the elastic stretchable member, for example, thread-, string- or band-shaped members made of natural rubber, synthetic rubber, polyurethane or the like may be appropriately used.

[0040] (Front and back side gathers) Front and rear side gathers (not shown) may be provided along the longitudinal direction at both widthwise ends of the pet absorbent article 10. The front and rear side gathers provide stretchability to both widthwise ends of the pet absorbent article 10, improving the fit to the pet's body.

[0041] (Fastening part) The fastening portion is a detachable part for fastening both longitudinal sides of the pet absorbent article 10 to each other when the pet absorbent article 10 is put on a pet, and is provided at one longitudinal end of the pet absorbent article 10.

[0042] In this embodiment, a mechanical hook tape (fastening part) 15 is used as the fastening part. The mechanical hook tape 15 is fixed to the non-skin side 12a of the backsheet 12 at one end in the longitudinal direction of the pet absorbent article 10 in a state of extending along the width direction. The mechanical hook tape 15 is a member having a plurality of hooks (not shown) on the non-skin side, and is a tape that is detachable from the topsheet 11. Note that the "mechanical hook tape" may also be called a "mechanical tape" or a "hook tape".

[0043] When the mechanical hook tape 15 is used as the fastening part as in this embodiment, a loop material or the like may be fixed at a position corresponding to the mechanical hook tape 15. The fastening part is not limited to the mechanical hook tape 15, and may be, for example, an adhesive layer made of a hot melt adhesive or the like, or an adhesive tape. In this embodiment, the fastening part (mechanical hook tape 15) is provided on the non-skin side (non-skin side 12a of the back sheet 12) of one end in the longitudinal direction of the absorbent article for pet 10, but is not limited thereto and may be provided on the skin side of one end in the longitudinal direction of the absorbent article for pet 10.

[0044] (Left and right leg straps) As shown in FIG. 1 and FIG. 3, the left and right leg belts 16 are belt-like members that can be wrapped around the left and right hind legs of a pet and attached to the pet, and are arranged at one end (rear end) of the back sheet 12 in the width direction and fixed to the back sheet 12. The left and right leg belts 16 are arranged spaced apart from each other in the longitudinal direction. The left and right leg belts 16 are arranged symmetrically with respect to an imaginary center line that passes through the center of the absorber 13 in the longitudinal direction and extends in the width direction. The left and right leg belts 16 extend backward (outside in the second direction) from the back sheet 12. Note that wrapping the left and right leg belts 16 around the left and right hind legs of a pet may mean that the left and right leg belts 16 extend along the entire circumference of the hind legs, or may mean that the left and right leg belts 16 extend along a partial region in the circumference of the hind legs (for example, the left and right side surfaces and rear surface of the hind legs). Each of the left and right leg belts 16 may be composed of one belt, or may be composed of two belts as in the present embodiment described later.

[0045] (Pair of belts) In this embodiment, each of the left and right leg belts 16 is composed of a pair of belts 16a, 16b. The left and right leg belts 16 are arranged symmetrically with respect to an imaginary center line that passes through the center of the absorber 13 in the longitudinal direction and extends in the width direction, so in the following, only one (right) leg belt 16 (a pair of belts 16a, 16b) will be described, and a description of the other will be omitted.

[0046] The pair of belts 16a, 16b are strip-shaped members extending in the front-rear direction, with their front ends fixed to the rear end of the back seat 12 and their rear ends extending rearward from the back seat 12. The pair of belts 16a, 16b in this embodiment are formed in a rectangular shape that is long in the front-rear direction. In this embodiment, the pair of belts 16a, 16b are arranged spaced apart from each other on the left and right, and extend linearly from the back seat 12 in the width direction (Y direction) backward in a state parallel to each other. The separation distance between the pair of belts 16a, 16b is set to a distance that allows the hind legs of a pet to be placed between the pair of belts 16a, 16b. In this embodiment, the pair of belts 16a, 16b extend rearward from the back seat 12 in a state parallel to each other, but this is not limited to this. For example, the front ends of the pair of belts 16a, 16b may be fixed to approximately the same position on the back seat 12, and the pair of belts 16a, 16b may extend in a V shape from the fixed position to both the left and right sides rearward.

[0047] (Belt fixing position) The connection portions of the pair of belts 16a, 16b (left and right leg belts 16) to the back sheet 12 may be fixed to the non-skin side of the back sheet 12. Alternatively, when the back sheet 12 is made of a composite sheet of the above-mentioned resin film 17 and nonwoven fabric 18, the connection portions of the pair of belts 16a, 16b (left and right leg belts 16) to the back sheet 12 may be fixed by being sandwiched between the resin film 17 and the nonwoven fabric 18. With this configuration, it is possible to prevent the connection portions of the left and right leg belts 16 from interfering with the pet's body, thereby reducing the discomfort of the pet.

[0048] (Belt fastening part) At least one of the pair of belts 16a, 16b has a belt fastening part that can be fastened to the other belt. The belt fastening part is a part that allows one belt to be attached and detached to the other belt. The left and right leg belts 16 are wrapped around the pet's hind legs with the pet's hind legs positioned between the pair of belts 16a, 16b, and can be attached to the left and right hind legs of the pet by fastening one of the belt fastening parts to the other belt.

[0049] In this embodiment, a mechanical hook tape (belt fastening portion) 19 is used as the belt fastening portion. The mechanical hook tape 19 as the belt fastening portion may be the same as or different from the mechanical hook tape 15 for attaching the pet absorbent article 10 to the pet's waist. In this embodiment, the mechanical hook tape 19 is provided on the belt 16a located on the outer side in the longitudinal direction.

[0050] In addition, when the mechanical hook tape 19 is used as the belt fastening part as in the present embodiment, a loop material or the like may be fixed to the other belt side. In addition, the belt fastening part is not limited to the mechanical hook tape 19, and may be, for example, an adhesive layer made of a hot melt adhesive or an adhesive tape. In addition, in Figs. 1 and 3, the mechanical hook tape 19 is provided on the belt located on the outer side in the longitudinal direction of the pair of belts 16a, 16b, but is not limited thereto, and may be provided on the belt located on the inner side in the longitudinal direction. In addition, when each of the left and right leg belts 16 is composed of a single belt, it is preferable to provide a belt fastening part at the tip of the belt.

[0051] (Leg belt configuration) The left and right leg belts 16 (a pair of belts 16a, 16b in this embodiment) preferably contain a strip-shaped nonwoven fabric, and more preferably contain, in addition to the strip-shaped nonwoven fabric, an elastic stretchable member that is stretchable in the extension direction of the leg belts 16. As shown in Figures 3 and 4, the left and right leg belts 16 in this embodiment contain two strip-shaped nonwoven fabrics 20 facing each other, and a plurality of elastic stretchable members 21 disposed between the two strip-shaped nonwoven fabrics 20 and fixedly provided to the two strip-shaped nonwoven fabrics 20.

[0052] The material of the strip-shaped nonwoven fabric 20 is not particularly limited, but is preferably an SMS nonwoven fabric or a spunbond nonwoven fabric, and more preferably a nonwoven fabric containing cellulosic fibers. By forming the strip-shaped nonwoven fabric 20 from a nonwoven fabric containing cellulosic fibers, the leg belt 16 can be made easy to put on and gentle on the skin. The basis weight of the strip-shaped nonwoven fabric 20 is 70 g / m 2 More than 100g / m 2 The weight of the strip-shaped nonwoven fabric 20 is preferably 70 g / m or less. 2 If the weight of the belt-shaped nonwoven fabric 20 is lower than 100 g / m, the leg belt 16 becomes easily broken and the belt-shaped nonwoven fabric 20 becomes easily stretched, resulting in poor fit. 2 If it is higher than this, it may become too hard and cause discomfort to your pet, and may also cause tangled fur due to rubbing and lead to skin irritation.

[0053] The elastic stretchable member 21 is provided along the extension direction of the leg belt 16 and is stretchable in the extension direction of the leg belt 16. For example, the elastic stretchable member 21 is fixed to two strip-shaped nonwoven fabrics 20 in a stretched state. Examples of the elastic stretchable member 21 include thread-, string- or strip-shaped elastic stretchable members made of natural rubber, synthetic rubber, polyurethane, etc. By providing the elastic stretchable member 21 on the left and right leg belts 16, it is possible to improve the fit when the left and right leg belts 16 are wrapped around the left and right hind legs of a pet.

[0054] (Modification of a pair of belts) In this embodiment, the pair of belts 16a, 16b are formed in a rectangular shape that is long in the front-rear direction, but the present invention is not limited to this.

[0055] For example, as shown in Fig. 5(a), a wide portion 22 may be provided at the leading end (rear end) of a pair of belts 16a, 16b, and a mechanical hook tape (belt fastening portion) 19 may be provided on the wide portion 22. This makes it possible to easily identify the position of the mechanical hook tape 19.

[0056] Alternatively, as shown in Fig. 5(b), the pair of belts 16a, 16b may be curved so that the intermediate portions in the extending direction (front-rear direction) bulge away from each other, which makes it easier for the pair of belts 16a, 16b to fit the hind legs of a pet.

[0057] Alternatively, as shown in Fig. 5(c), the edges of the pair of belts 16a, 16b on both the left and right sides may be formed in a wavy line shape, which can reduce the irritation of the pet's hind legs from the edges of the belts 16a, 16b.

[0058] (How to use) Next, there will be described an example of a method of using the pet absorbent article 10. Note that the method of using the pet absorbent article 10 described below is just one example, and the pet absorbent article 10 can also be used in other modes.

[0059] Fig. 6 is an explanatory diagram of a pet wearing an absorbent article for pets, viewed from the side. Fig. 7 is an explanatory diagram of a pet wearing an absorbent article for pets, viewed from behind.

[0060] As shown in Fig. 6 and Fig. 7, the pet absorbent article 10 is attached to the waist of the pet P so that its longitudinal direction is the circumferential direction of the waist of the pet P and its width direction is the front-rear direction of the pet P. When attaching the pet absorbent article 10 to the pet P, first, the pet absorbent article 10 is placed under the waist of the pet P with the top sheet 11 side facing the skin side of the pet P and the left and right leg belts 16 on the rear side. Next, both ends of the pet absorbent article 10 in the longitudinal direction are lifted so as to cover the urination part of the pet P from below, and the pet absorbent article 10 is wrapped around the waist of the pet P, and the mechanical hook tape 15 on one end is fastened to the other end to be fastened. Finally, the left and right leg belts 16 are wrapped around the left and right hind legs HL of the pet P and attached. For example, in this embodiment, the hind legs HL of the pet P are placed between the pair of belts 16a, 16b, and the pair of belts 16a, 16b are wrapped around the rear sides of the hind legs HL, and one mechanical hook tape 19 is fastened to the other. This allows the pet absorbent article 10 to be worn by the pet P and used.

[0061] The pet absorbent article 10 configured as described above includes left and right leg belts 16 that are disposed on the rear end side of the back sheet 12, extend rearward from the back sheet 12, and can be attached to the left and right hind legs HL of the pet P. Therefore, since the left and right leg belts 16 can be attached to the hind legs HL of the pet P when the pet is put on, it is possible to reliably prevent the pet absorbent article 10 from rotating relative to the body (torso) of the pet P even if the pet P moves vigorously.

[0062] Furthermore, even if the absorbent article for pet 10 does not fit the pet's body shape, rotation of the absorbent article for pet 10 with respect to the pet P's torso can be reliably prevented.

[0063] Furthermore, since the left and right leg belts 16 are attached to the hind legs HL of the pet P when the absorbent article 10 is put on, it is possible to reliably prevent the pet absorbent article 10 from shifting (moving) forward relative to the body (torso) of the pet P. This makes it possible to prevent misalignment between the position of the pet P's private parts and the position of the absorber 13, making it difficult for urine leakage to occur.

[0064] In this way, according to this embodiment, it is possible to prevent the pet absorbent article 10 from shifting or rotating relative to the body. This prevents misalignment between the position of the pet P's private parts and the position of the absorber 13, making urine leakage less likely to occur.

[0065] In addition, since the left and right leg belts 16 extending rearward from the back seat 12 are fixed to the back seat 12, the left and right leg belts 16 can move easily relative to the absorbent main body, unlike a case where, for example, openings are provided in the portion of the pet absorbent article 10 excluding the left and right leg belts 16 (hereinafter referred to as the "absorbent main body") for inserting the left and right hind legs HL of the pet P. Therefore, the pet absorbent article 10 can be worn in a state where the pet P can move easily.

[0066] In addition, since the left and right leg belts 16 are easy to move relative to the absorbent body, it is possible to suppress the movement of the absorbent body in the direction of the pet P's waist caused by the movement of the hind legs HL of the pet P. This makes it possible to suppress the occurrence of skin rashes and tangled hair caused by friction between the absorbent body and the pet P's body.

[0067] Furthermore, when putting the pet absorbent article 10 on the pet P, the pet P may move, making it difficult to put on the pet absorbent article 10, and the pet may end up putting it on loosely around the pet's waist. Even in such a case, the left and right leg belts 16 are attached to the hind legs HL of the pet P, so that rotation or shifting of the pet absorbent article 10 in the waist direction can be suppressed, and urine leakage can be prevented.

[0068] In addition, the left and right leg belts 16 can be attached to the hind legs HL by adjusting the tightness according to the thickness of the hind legs HL of the pet P, so that the pet P can be accommodated to pets P having hind legs HL of various thicknesses, and the fit is improved.

[0069] Furthermore, since the left and right leg belts 16, which are separate from the absorbent body, are fixed to the absorbent body (back sheet 12), it can be easily manufactured and material costs can be reduced, unlike when the member supporting the hind legs HL of pet P is integrally molded with the absorbent body.

[0070] Furthermore, by forming the backsheet 12 into a composite sheet in which a resin film (film portion) 17 on the skin side and a nonwoven fabric (nonwoven fabric portion) 18 located on the non-skin side of the resin film 17 are laminated, the nonwoven fabric 18 is exposed to the outside when worn, improving the feel of the non-skin side of the backsheet 12. In addition, the nonwoven fabric 18 being exposed to the outside when worn gives the garment a clothing-like feel, which also makes for a pleasing appearance.

[0071] Furthermore, by using the mechanical hook tape 15 as the fastening part, unlike when the fastening part is an adhesive layer or adhesive tape, it is easy to reattach, and the length of the waist circumference of the pet absorbent article 10 can be easily adjusted.

[0072] Furthermore, by using the mechanical hook tape 19 as the belt fastening portion, unlike when the belt fastening portion is an adhesive layer or adhesive tape, it is easy to reattach, and the tightness of the left and right leg belts 16 relative to the left and right hind legs HL of the pet P can be easily adjusted.

[0073] Although the present invention has been described based on the above embodiment, the present invention is not limited to the contents of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.
