The partition wall 235 has a rectangular plate-like partition front wall 2350 facing the rear opening 2320, and a pair of left and right partition side walls 2351 extending rearward from the left and right ends of the partition front wall 2350. A notch 2352 that penetrates the partition front wall 2350 in the front-rear direction and opens upward is provided at the upper end of the partition front wall 2350.

[0058] In this embodiment, a partition front wall 2350 protrudes upward from the front edge of the connecting wall portion 2303 of the bottom wall 230, and a pair of partition side walls 2351 protrude upward from the left and right edges of the connecting wall portion 2303. The space surrounded by the partition wall 235 is open to the rear through the rear opening 2320. Functional parts for the toilet 1, such as a deodorizing device, can be appropriately installed in this space. In addition, the partition wall 235 prevents the tray 5 and the bag 10 placed thereon from being exposed through the rear opening 2320.

[0059] 8 and 11, each of the pair of left and right side walls 233 is provided with a recess 2330 that is recessed inward in the left-right direction, extends to the lower ends of the side walls 233, and is open downward. In other words, each of the left and right side surfaces of the toilet body 2 is provided with a recess 2330 that is recessed inward in the left-right direction, extends to the lower ends of both side surfaces, and is open downward.

[0060] More specifically, a recess 2330 that is recessed to the left, extends to the bottom end of the right face, and is open downward is provided in the right face of the right side wall 233. And a recess 2330 that is recessed to the right, extends to the bottom end of the left face, and is open downward is provided in the left face of the left side wall 233.

[0061] The recess 2330 is a rectangular recess when viewed in the left-right direction. The recess 2330 is disposed in the center in the front-rear direction of the left and right side walls 233. Each of the left and right side walls 233 has a finger hook surface 2331 that is located above the recess 2330 and faces downward. The finger hook surface 2331 is provided with unevenness 2332 for preventing slipping.

[0062] The unevenness 2332 is provided on the finger hook surface 2331 in the center in the front-to-rear direction of the toilet body 2. In this embodiment, the unevenness 2332 is provided on a portion of the finger hook surface 2331 closer to the front. The unevenness 2332 is located in a position that makes it easy to balance the toilet 1 when lifting and carrying the toilet 1 by hooking fingers on the unevenness 2332.

[0063] In this embodiment, the unevenness 2332 is configured with a plurality of protrusions 2333 extending in the front-rear direction and arranged at intervals in the left-right direction. The plurality of protrusions 2333 protrude downward from the finger hook surface 2331. In this embodiment, the length of each of the plurality of protrusions 2333 in the front-rear direction is set to 20 mm or more and 40 mm or less, which is a length that makes it easy to hook a finger. Note that the length of each of the plurality of protrusions 2333 in the front-rear direction may be any length that makes it easy to hook a finger, and is not limited to the above range.

[0064] In this embodiment, the multiple protrusions 2333 are formed from the same material as the left and right side walls 233, and are molded integrally with the left and right side walls 233 when the lower part 23 is molded. Note that the multiple protrusions 2333 may be formed from a material different from that of the left and right side walls 233, and may be attached to the finger hook surface 2331 by a fixing means such as an adhesive.

[0065] Because the left and right side walls 233 have recesses 2330 in this way, when a caregiver stands to the side (left and right) of the toilet 1 to assist the user's movements, the caregiver can easily insert their toes under the toilet 1 and easily exert force to support the user.

[0066] 2-1-6.Frame The frame 21 shown in Fig. 6 is composed of a first frame portion 21a and a second frame portion 21b attached below the left and right ends of the outer part 25. The frame 21 is housed in the lower part 23. The frame portions 21a and 21b are disposed on a pair of left and right wall portions 2301 of the lower part 23. Note that Fig. 6 shows a state in which the four legs 7 and the reinforcing plate 16 are attached to the frame 21, but the four legs 7 and the reinforcing plate 16 are attached to the frame 21 after it is housed in the lower part 23.

[0067] The first frame portion 21a and the second frame portion 21b have a common structure. A pair of reinforcing plates 16 connected in an X-shape in plan view are connected to the lower end of the first frame portion 21a and the lower end of the second frame portion 21b. Each of the pair of reinforcing plates 16 is a strip-shaped member extending in one direction. The pair of reinforcing plates 16 are connected in an X-shape in plan view by connecting the central portions of the pair of reinforcing plates 16 to each other in the longitudinal direction. Both ends of the pair of reinforcing plates 16 in the longitudinal direction are fixed to the lower surfaces of the first frame portion 21a and the second frame portion 21b.

[0068] Each of the first frame portion 21a and the second frame portion 21b has a pair of front and rear leg attachment portions 210 and a connecting wall 211 connecting the pair of front and rear leg attachment portions 210. A fixing portion 212 used for fixing to the outer part 25 is provided at the upper end of the connecting wall 211. In this embodiment, the fixing portion 212 is a cylindrical portion with a bottom that opens upward. A pair of reinforcing plates 16 are fixed to the lower end of the connecting wall 211.

[0069] Each of the pair of front and rear leg attachment parts 210 is configured so that the length of the leg 7 protruding downward from the leg attachment part 210 can be adjusted. The leg 7 and the leg attachment part 210 are provided with a connection structure that allows the length of the leg 7 protruding downward from the leg attachment part 210 to be adjusted. In this embodiment, the pair of front and rear leg attachment parts 210 have a common structure.

[0070] 14 and 15, the leg attachment part 210 has a cylindrical tube part 213, a protrusion 214 that protrudes from a lower part of the inner peripheral surface of the tube part 213 and extends in the circumferential direction, and a plurality of vertical ribs 215 that protrude from a lower part of the inner peripheral surface of the tube part 213 and extend in the up-down direction. The leg attachment part 210 further has a through hole 216 provided in a part of the circumferential direction of the lower end part of the tube part 213, and a retaining part 218 provided around the through hole 216 on the outer peripheral surface of the tube part 213. The frame 21 further has a restricting tool 217 that can be operated inside the housing 20 and can restrict the movement of the leg 7 relative to the leg attachment part 210.

[0071] The protrusion 214 is configured to restrict the vertical movement of the leg 7 by hooking onto a part of the leg 7. Two protrusions 214 are provided at an interval in the circumferential direction on the lower part of the inner peripheral surface of the tube portion 213. Each of the two protrusions 214 is an arc-shaped protrusion in a plan view extending in the circumferential direction. In this embodiment, the two protrusions 214 are provided at an interval of 180 degrees in the circumferential direction so as to face each other. The tube portion 213 and the two protrusions 214 form a connection structure on the leg attachment portion 210 side that allows the length of the leg 7 protruding downward from the leg attachment portion 210 to be adjusted.

[0072] The multiple vertical ribs 215 are configured to abut against the leg 7 to suppress inclination of the leg 7 within the leg attachment part 210. The vertical ribs 215 are shorter in the radial direction (i.e., in the direction perpendicular to the central axis of the tube part 213) than the protrusion 214. Six vertical ribs 215 are provided on the lower part of the inner peripheral surface of the tube part 213. The six vertical ribs 215 include three vertical ribs 215a, 215b, 215c arranged around one protrusion 214 and three vertical ribs 215a, 215b, 215c arranged around the other protrusion 214. The arrangement of the three vertical ribs 215a, 215b, 215c relative to one protrusion 214 is the same as the arrangement of the three vertical ribs 215a, 215b, 215c relative to the other protrusion 214. The longitudinal ribs 215a, 215b, 215c are arranged in this order at intervals in the circumferential direction.

[0073] The vertical rib 215a has a portion extending upward from the upper surface of one circumferential end of the protrusion 214, and a portion extending downward from the lower surface of one circumferential end of the protrusion 214. The vertical rib 215b extends upward from the upper surface of the other circumferential end of the protrusion 214. The vertical rib 215c extends downward from a position on the inner circumferential surface of the tube portion 213 that is offset circumferentially from the protrusion 214, at approximately the same vertical position as the upper surface of the protrusion 214.

[0074] The through hole 216 is disposed at a position shifted circumferentially and downwardly with respect to the protrusion 214. The through hole 216 is also disposed at a position shifted circumferentially with respect to the vertical rib 215c. The through hole 216 penetrates a part of the tubular portion 213. A restricting tool 217 is inserted into the through hole 216, so that a tip end of the restricting tool 217 protrudes into the tubular portion 213.

[0075] The retaining portion 218 is provided on the outer circumferential surface of the tube portion 213, the surface facing the storage space S1. Therefore, the restricting tool 217 can be operated in the storage space S1. The restricting tool 217 can be operated with the lid 6 open and the tray 5 removed.

[0076] The stopper portion 218 is configured to catch and stop the restrictor 217 at a locking position (see FIG. 14) where the tip of the restrictor 217 protrudes into the tube portion 213, and at a standby position retracted radially outward from the locking position. In this embodiment, the restrictor 217 has a movable portion 2170 that can move between a position where it is caught by the stopper portion 218 and a position where it is not caught. By grasping the movable portion 2170, the restrictor 217 is released from the state where it is caught by the stopper portion 218, and can be moved between the locking position and the standby position. When the restrictor 217 is in the locking position, it can restrict the movement of the leg 7 relative to the leg attachment portion 210.

[0077] 2-1-7. Legs 15 is attached to each of the four leg attachment parts 210 of the frame 21. The four legs 7 have a common structure. The four legs 7 can be raised and lowered independently of each other, and the amount by which they protrude downward from the leg attachment parts 210 can be adjusted.

[0078] The leg 7 has a cylindrical pillar portion 70, a base portion 71 protruding radially outward from the lower end of the pillar portion 70, and a disk-shaped anti-slip portion 72 attached to the lower surface of the base portion 71.

[0079] The leg 7 is configured to be fixed to the leg mounting part 210 by rotating the column portion 70 circumferentially while inserting the desired length into the tubular portion 213 of the leg mounting part 210 and placing the regulating device 217 in the locking position.

[0080] The pillar portion 70 is provided with two rows of protrusion groups 73 each composed of a plurality of protrusions 730 aligned in a row in the vertical direction. The pillar portion 70 is further provided with a restricting portion 74 located between two adjacent protrusions 730 in the vertical direction. In other words, the pillar portion 70 is provided with a plurality of restricting portions 74.

[0081] In this embodiment, the multiple protrusions 730 include multiple protrusions that are rectangular frame-shaped when viewed in the radial direction and multiple protrusions that are rectangular when viewed in the radial direction. Of the multiple protrusions 730, one protrusion 730 located at the bottom is rectangular, and the remaining multiple protrusions 730 are rectangular frame-shaped.

[0082] Each of the rectangular frame-shaped protrusions 730 integrally includes two vertical ribs 730a extending in the vertical direction and spaced apart in the circumferential direction, and two horizontal ribs 730b extending in the circumferential direction and spaced apart in the vertical direction. The restricting portion 74 is a straight rib extending in the vertical direction. The restricting portion 74 is bridged between one of the two vertical ribs 730a of the two protrusions 730 adjacent to each other in the vertical direction. Therefore, one of the vertical ribs 730a of the multiple protrusions 730 and the multiple restricting portions 74 form a straight vertical rib extending in the vertical direction. The lowest restricting portion 74 is continuous with one end of the rectangular protrusion 730 in the circumferential direction, and the surface on one side of the lowest restricting portion 74 in the circumferential direction and the surface on the same side of the lowest protrusion 730 are continuous and flush with each other.

[0083] The pillar portion 70 has a plurality of locking grooves 75 formed therein, each of which is surrounded by two vertically adjacent protrusions 730 and a restricting portion 74 between them. The protrusions 214 of the leg attachment portion 210 can be inserted into each of the plurality of locking grooves 75 up to a position where they come into contact with the restricting portion 74.

[0084] Two slide grooves 76 extending in the vertical direction are formed between the two rows of protrusion groups 73 of the pillar portion 70. Each of the two slide grooves 76 opens upward and radially outward. When the pillar portion 70 is moved up and down relative to the leg attachment portion 210, two protrusions 214 are arranged in the two slide grooves 76, allowing the leg 7 to move up and down.

[0085] The above-mentioned pillar portion 70 of leg 7, two rows of protrusions 73, multiple regulating portions 74, multiple locking grooves 75, and two slide grooves 76 constitute a connection structure on the leg 7 side that allows the length of leg 7 protruding downward from the leg mounting portion 210 to be adjusted.

[0086] A hollow disk-shaped base portion 71 protrudes radially outward from the lower end of the pillar portion 70. A disk-shaped anti-slip portion 72 is attached to the underside of the base portion 71. The anti-slip portion 72 has the same diameter as the base portion 71. As shown in FIG. 11, the underside of the anti-slip portion 72 is provided with anti-slip irregularities 720. The anti-slip portion 72 is made of, for example, rubber. The pillar portion 70 and the base portion 71 are made of synthetic resin and are molded integrally.

[0087] The leg 7 described above is inserted from below into the tube portion 213 of the leg attachment portion 210 of the frame 21. The leg 7 is rotated in the circumferential direction at a desired vertical position, and the protrusion 214 of the leg attachment portion 210 is inserted into one of the multiple locking grooves 75 lined up and down on the leg 7 and abuts against the restricting portion 74, thereby temporarily fixing the vertical and circumferential positions of the leg 7.

[0088] Thereafter, the restricting tool 217 is moved from the standby position to the locking position, and the restricting portion 74 is sandwiched in the circumferential direction by the tip of the restricting tool 217 and the adjacent protrusion 214, thereby restricting the circumferential movement of the leg 7. This makes it possible to restrict the vertical and circumferential movement of the leg 7, and fix the leg 7 to the leg attachment portion 210.

[0089] Furthermore, the pillar portions 70 of the legs 7 come into contact with the vertical ribs 215 inside the tube portion 213, thereby preventing the pillar portions 70 from tilting relative to the tube portion 213. The legs 7 are attached to the leg attachment portions 210 with respect to the frame 21 housed in the lower part 23. The four legs 7 are attached to the four leg attachment portions 210, respectively, in the manner described above.

[0090] 10 and 11B, in a plan view, each of the four legs 7 is located inside the outer circumferential surface of the toilet body 2. Therefore, when the toilet body 2 is viewed from directly above, the four legs 7 are hidden by the toilet body 2 and cannot be seen.

[0091] As shown in Fig. 1, the two left and right legs 7 located on the front side are spaced apart in the left-right direction, and the two front and rear legs 7 located on both the left and right sides are spaced apart in the front-rear direction. As shown in Fig. 7, a foot insertion space S3 into which the heels of a user sitting on the toilet seat 3 can be inserted is formed between the two left and right legs 7 located on the front side. The foot insertion space S3 is located below the foot insertion recess 61, and the foot insertion space S3 and the foot insertion recess 61 are in communication with each other.

[0092] 8, a foot insertion space S4 is formed between the two front and rear legs 7 located on both the left and right sides, into which a caregiver can insert the feet of a user who is using the toilet 1. The foot insertion space S4 is located below the recess 2330, and the foot insertion space S4 and the recess 2330 are connected to each other.

[0093] In this embodiment, as shown in Figs. 4 and 16, a fixing member 17 for fixing the toilet 1 to the base 9 of the toilet handrail 8 is attached to each of the two rear legs 7.

[0094] 2-1-8. Fixing material 16, the fixing member 17 integrally includes a leg connection part 170 connected to the leg 7, and a base fixing part 171 fixed to the base 9. In this embodiment, the toilet 1 is fixed to the base 9 of the toilet handrail 8 using two fixing members 17. The two fixing members 17 have a common structure.

[0095] 17 and 18A to 18C, the leg connection part 170 is composed of a cover member 173 provided with an insertion hole 172 through which the pillar part 70 of the leg 7 is inserted. The cover member 173 is shaped so that the base part 71 of the leg 7 fits inside.

[0096] In this embodiment, the cover member 173 has a top plate portion 1730 that presses the base portion 71 of the leg 7 from above, and a peripheral wall portion 1731 that protrudes downward from the top plate portion 1730 so that the base portion 71 fits inside. The top plate portion 1730 has an insertion hole 172 in the center thereof through which the column portion 70 of the leg 7 is inserted. In this embodiment, the top plate portion 1730 is annular in plan view. The peripheral wall portion 1731 extends cylindrically downward from the outer circumferential edge portion of the top plate portion 1730.

[0097] A plurality of ribs 1732 extending in the up-down direction are provided at intervals in the circumferential direction on the inner peripheral surface of the peripheral wall portion 1731. The plurality of ribs 1732 are arranged at equal intervals over the entire circumferential length on the inner peripheral surface of the peripheral wall portion 1731. The plurality of ribs 1732 come into contact with the base portion 71 of the leg 7, so that the base portion 71 fits into the cover member 173.

[0098] The base fixing portion 171 protrudes radially outward from a portion of the circumferential direction of the peripheral wall portion 1731. The base fixing portion 171 integrally includes a tip portion 1710 located on the tip side in the protruding direction, and a base portion 1711 continuous with the peripheral wall portion 1731.

[0099] The upper surface of base 1711 is inclined so that the portion farther from peripheral wall 1731 is positioned lower. The lower surface of base 1711 is flat and has a constant up-down position over the entire radial length. The lower surface of base 1711 is provided with a plurality of recesses 1712 to reduce weight.

[0100] The tip 1710 is shorter in the up-down direction than the base 1711. The tip surface of the tip 1710 forms a curved surface 1713 in a convex arc shape toward the base 1711. The upper surface of the tip 1710 is located lower than the upper surface of the base 1711. At the boundary between the upper surface of the tip 1710 and the upper surface of the base 1711, a step surface 1714 that is curved in a V-shape in plan view is formed. The step surface 1714 has a shape that corresponds to the outer shape of the cover 116 of the handrail 11. As a result, a cover storage recess 1715 in which the cover 116 is stored is formed on the upper surface of the tip 1710.

[0101] The tip side portion of the lower surface of the tip portion 1710 is located higher than the base 1711 side portion of the lower surface of the tip portion. At the boundary between the tip side portion of the lower surface of the tip portion 1710 and the base 1711 side portion, a step surface 1716 that is curved in a V shape in a plan view is formed. The step surface 1716 is provided so as to abut against the flange portion 115 of the handrail 11. As a result, a flange storage recess 1717 that stores the flange portion 115 of the handrail 11 is formed on the lower surface of the tip portion 1710. The step surface 1716 is located closer to the tip side than the step surface 1714.

[0102] The tip portion 1710 is provided with a through hole 1718 through which a fastener 174 such as a screw is inserted to fasten the fixing member 17 to the flange portion 115 of the handrail 11. The through hole 1718 is located on the tip side of the step surface 1714 and the step surface 1716. In this embodiment, the fastener 174 is longer than the fastener 117 that fastens the flange portion 115 of the handrail 11 to the base 9.

[0103] The fixing members 17 are attached to the two rear legs 7 before the two rear legs 7 are attached to the frame 21 of the toilet body 2. After the toilet 1 is placed on the base 9, the base fixing parts 171 of the two fixing members 17 are fixed to the left and right flange parts 115 of the handrail 11 with fasteners 174, thereby fixing the toilet 1 to the toilet handrail 8.

[0104] The left and right flanges 115 of the handrail 11 come into contact with the step surfaces 1716 of the two fixing members 17, restricting rotational movement of each fixing member 17 about the fixture 174, and as a result, the toilet 1 is fixed in a position relative to the toilet handrail 8. Therefore, even though the toilet 1 has a cubic shape, it can be installed stably.

[0105] The fixing member 17 is not limited to the structure shown in Fig. 18A to C. The fixing member 17 may have a fixing device storage recess 1719 capable of storing a fixing device 117 for fixing the flange portion 115 of the handrail 11 to the base 9 on the lower surface of the base portion 1711 of the base fixing portion 171 as in the first modified example shown in Fig. 19. The fixing device storage recess 1719 communicates with the recess 1712. The head and a part of the shaft of the fixing device 117 are housed in the recess 1712, and the remaining part of the shaft of the fixing device 117 is fitted into the fixing device storage recess 1719. The fixing device storage recess 1719 may be formed so as to communicate with the space inside the peripheral wall portion 1731 as well.

[0106] In the first modification, when an unusable fastener 117 occurs when overlapping the base fixing portion 171 of the fixing member 17 with the flange portion 115 of the handrail 11, this fastener 117 can be stored in the fastener storage recess 1719. Therefore, when the toilet 1 is removed and only the toilet handrail 8 is used, the stored fastener 117 can be reused.

[0107] 20A to 20C, fixing member 17 may have leg connection portion 170 that is U-shaped in plan view and may be connected to base portion 71 of leg 7 by engagement. Fixing member 17 of modification 2 is made of metal and is formed by bending a metal plate.

[0108] The fixing member 17 of the second modification has a top plate portion 1730a having a U-shape in plan view and having a semi-elliptical notched through-hole 172a through which the column portion 70 of the leg 7 is inserted, and a rectangular side plate portion 175 extending at a right angle from one end of the top plate portion 1730a. The fixing member 17 of the second modification further has a rectangular lower plate portion 176 extending at a right angle from the lower end of the side plate portion 175 toward the opposite side to the top plate portion 1730a. The lower plate portion 176 is provided with a through hole 1718. The top plate portion 1730a and the side plate portion 175 form the leg connecting portion 170, and the lower plate portion 176 forms the base fixing portion 171.

[0109] 21A to 21C, the fixing member 17 may have a leg connection part 170 in the shape of a semi-rectangular frame in plan view, and may be connected to the base part 71 of the leg 7 by fitting. The fixing member 17 of the modification 3 is made of metal, and is formed by bending and welding a metal plate, for example.

[0110] The fixing member 17 of the third modification has a semi-rectangular frame-like top plate portion 1730b in plan view, in which a rectangular notched insertion hole 172b is provided through which the column portion 70 of the leg 7 is inserted, and a peripheral wall portion 1731b formed of three side plate portions 175a extending downward at right angles from three sides of the outer periphery of the top plate portion 1730b. The fixing member 17 of the third modification further has a rectangular lower plate portion 176a extending at right angles from one of the three side plate portions 175a toward the opposite side to the top plate portion 1730b. The lower plate portion 176a is provided with a through hole 1718. The three side plate portions 175a are formed so that the base portion 71 of the leg 7 fits inside (in other words, sandwiches it from three sides). The top plate portion 1730b and the three side plate portions 175a constitute the leg connecting portion 170, and the bottom plate portion 176a constitutes the base fixing portion 171.

[0111] 2-1-9. Sealing unit The toilet 1 of this embodiment further includes a sealing unit 18 shown in Fig. 5. The sealing unit 18 has a bag attachment portion 14 and a sealing device 15. The sealing unit 18 is installed between an inner part 24 and an outer part 25.

[0112] 22 and 23 show the sealing unit 18 with the internal parts 24 removed. As shown in Fig. 5, the sealing unit 18 has a flat box-shaped case 180 with an open top, and the bag attachment part 14 and the sealing device 15 installed in the case 180. An opening 182 is provided in a bottom wall 181 of the case 180, penetrating the bottom wall 181 in the vertical direction.

[0113] 2-1-10. Bag attachment part 3, bag attachment part 14 is configured to be detachably attached in a state in which mouth 100 of bag 10 for receiving the user's excrement is open. The bottom surface of bag 10 in a state in which mouth 100 is attached to bag attachment part 14 is supported by tray 5. Therefore, the downward load acting on bag 10 is mainly supported by tray 5.

[0114] The bag attachment part 14 is configured so that the mouth 100 of the bag 10 can be detachably attached thereto. The bag attachment part 14 has a first attachment part 140 to which the first part 100a of the mouth 100 of the bag 10 is detachably attached, and a second attachment part 141 to which the second part 100b is detachably attached, out of the first part 100a and the second part 100b that face each other.

[0115] 22 and 23 , in this embodiment, the first mounting portion 140 is disposed in a portion of the bottom wall 181 in front of the opening 182. When the inner part 24 is attached onto the sealing unit 18, the first mounting portion 140 is located below the front edge of the upper surface opening 2400 of the inner part 24.

[0116] The second mounting portion 141 is installed on a movable portion 151 that moves in the front-rear direction by operation of an operation portion 150 provided in the sealing device 15. Therefore, the second mounting portion 141 is movable in the front-rear direction.

[0117] When the inner part 24 is attached onto the sealing unit 18 and the movable part 151 and the second mounting part 141 are in the rear end position, the second mounting part 141 is positioned below the rear edge of the upper surface opening 2400 of the inner part 24.

[0118] 2-1-11. Sealing device The sealing device 15 is configured to be able to seal the mouth 100 of the bag 10. In this embodiment, the sealing device 15 has an operation unit 150 operated by a user or a caregiver, a movable unit 151 that moves back and forth in response to the operation of the operation unit 150, and a connecting unit 152 that connects the operation unit 150 and the movable unit 151. The sealing device 15 further has a thermocompression unit 153 (see FIG. 12) that thermocompresses the mouth 100 of the bag 10 in the closed state. The operation unit 150, the movable unit 151, the connecting unit 152, and the thermocompression unit 153 are provided below a bottom wall 181 of the case 180.

[0119] The operating unit 150 is an arc-shaped member extending in the left-right direction and projecting forward in a plan view, and protrudes forward beyond the front wall 183 of the case 180 (see FIG. 5). The operating unit 150 is inserted into the insertion portion 254 of the outer part 25 and exposed to the front side of the toilet body 2.

[0120] Movable part 151 is a block-shaped member extending in the left-right direction. Second attachment part 141 is fixed to the upper surface of movable part 151. A pressing plate 154 for pressing bag 10 from behind is rotatably suspended from the lower surface of movable part 151. The front surface of movable part 151 forms pressing surface 1510 that presses part of mouth 100 of bag 10 against thermocompression part 153.

[0121] 22 and 23, the connecting portion 152 has a pair of left and right rod-shaped connecting members 1520. The left connecting member 1520 is connected to the left end of the operation portion 150 and the left end of the movable portion 151, and the right connecting member 1520 is connected to the right end of the operation portion 150 and the right end of the movable portion 151.

[0122] Each of the pair of left and right connecting members 1520 has a front part 1520a connected to the operation unit 150 and a rear part 1520b connected to the movable unit 151. The rear end of the front part 1520a is connected to the front end of the rear part 1520b so as to be rotatable around an axis parallel to the left-right direction.

[0123] 22 to a front end position where the pressing surface 1510 of the movable part 151 abuts against the thermocompression bonding part 153 via the mouth 100 of the bag 10. Then, the operation part 150 can rotate and move rearward and upward from the front end position to a thermocompression position where the pressing surface 1510 abuts against the thermocompression bonding part 153. When the operation part 150 is in the thermocompression position, the thermocompression bonding part 153 heats the mouth 100 of the bag 10 to seal it by thermocompression. After being moved from the thermocompression position to the front end position, the operation part 150 can be moved from the front end position to the storage position.

[0124] When the operating part 150 is moved from the storage position to the front end position, a pressing plate 154 rotatably suspended from the movable part 151 can press the part of the bag 10 below the mouth 100 on the rear face thereof to move it forward.

[0125] The sealing device 15 further has a pair of left and right pressing devices 155 that operate when the operating part 150 is moved from the storage position to the front end position to move the left and right parts of the mouth 100 of the bag 10 inward. The pair of left and right pressing devices 155 are disposed on the upper surface of the bottom wall 181 of the case 180, at the left and right parts of the opening 182.

[0126] In the sealing unit 18 described above, by moving the operating part 150 from the storage position to the front end position, the second part 100b of the mouth 100 of the bag 10 is brought closer to the first part 100a, and the left and right parts of the mouth 100 of the bag 10 can be sandwiched between the second part 100b and the first part 100a. Then, by rotating the operating part 150 to move it from the front end position to the thermocompression position, the thermocompression part 153 is activated and heats up, and the first part 100a and the part of the mouth 100 of the bag 10 slightly below the second part 100b can be melted and sealed by thermocompression.

[0127] By moving the operating part 150 from the heat bonding position to the front end position, and then moving it backward from the front end position to the storage position, the second part 100b of the mouth 100 of the sealed bag 10 is released from the second attachment part 141. At this time, the state in which the first part 100a of the mouth 100 of the sealed bag 10 is attached to the first attachment part 140 is maintained, and the mouth 100 of the sealed bag 10 is supported by the first attachment part 140.

[0128] In the toilet bowl 1 of this embodiment, the toilet seat 3 and the toilet lid 4 are opened to open the top opening 2400, and the mouth 100 of the sealed bag 10 is grasped from the top opening 2400 and pulled upward, whereby the first portion 100a of the mouth 100 of the bag 10 is detached from the first attachment portion 140. In this embodiment, the bag 10 with the mouth 100 detached from the first attachment portion 140 is placed on the tray 5. The bag 10 can then be removed through the side opening 2311. At this time, in the toilet bowl 1 of this embodiment, the tray 5 with the sealed bag 10 placed on it can be removed forward through the side opening 2311. At this time, since the bag 10 can be removed while placed on the tray 5, the bag 10 can be removed without touching it. Also, at this time, if wastewater has flowed down the outer surface of the bag 10 to the top of the tray 5, the tray 5 can be washed.

[0129] 2-1-12. Tray 3, tray 5 is disposed in a position where the bottom surface of bag 10 rests when mouth 100 is attached to bag attachment part 14. By receiving the bottom surface of bag 10, tray 5 supports the downward load acting on bag 10 from the excrement inside bag 10.

[0130] 11, the left and right ends and the rear end of the tray 5 are supported by a tray support part 2305 provided on the bottom wall 230 of the lower part 23 and a pair of left and right support plates 26. As a result, the tray 5 is disposed at the lower end of the storage space S1. The tray 5 is provided so as to be removable through a side opening 2311.

[0131] As shown in Figures 24A to 24C, the upper surface 50 of the tray 5 has a bottom surface 500 that constitutes the lowest part of the upper surface 50, and a number of inclined surfaces 501 that are positioned surrounding the bottom surface 500 and slope downward toward the bottom surface 500.

[0132] In this embodiment, the tray 5 is rectangular in plan view. The tray 5 has a peripheral wall portion 51 that is a rectangular frame in plan view and protrudes upward from the outer circumferential end of the top surface 50. The tray 5 further has a front wall 52 that connects the front end of the top surface 50 to the peripheral wall portion 51 above it. The front wall 52 is a trapezoidal wall in front view. The rear surface of the front wall 52 is slightly inclined with respect to the vertical plane so that the lower portion is positioned further rearward. The tray 5 further has a locking piece 53 that protrudes downward from the rear end. The locking piece 53 is hooked into a locking groove 23050 (see FIG. 11) of the tray support portion 2305 of the bottom wall 230.

[0133] The lowest surface 500 is a portion of the upper surface 50 that is forward of the center in the left-right and front-rear directions. The lowest surface 500 is flat and has a constant up-down position over the entire surface. The multiple inclined surfaces 501 include a first inclined surface 501a located in front of the lowest surface 500, a pair of second inclined surfaces 501b located on the left and right of the lowest surface 500, and a third inclined surface 501c located behind the lowest surface 500.

[0134] Each of the first inclined surface 501a, the pair of second inclined surfaces 501b, and the third inclined surface 501c is a plane inclined so that the portion closer to the bottom surface 500 is positioned lower. In this embodiment, the first inclined surface 501a is triangular in plan view, and is inclined so that the portion closer to the rear is positioned lower. The pair of left and right second inclined surfaces 501b are trapezoidal in plan view, and are inclined so that the portion closer to the inner side in the left and right direction is positioned lower. The third inclined surface 501c is triangular in plan view, and is inclined so that the portion closer to the front is positioned lower. The front end of the first inclined surface 501a and the front end of the pair of second inclined surfaces 501b are continuous with the lower end of the rear surface of the front wall 52.

[0135] The bottom surface of the bag 10 with the mouth 100 attached to the bag attachment portion 14 rests on the upper surface 50 of the tray 5. As a result, the waste contained in the bag 10 is guided toward the bottom surface 500 by the multiple inclined surfaces 501 of the upper surface 50, and can be concentrated at the center front side of the bottom surface of the bag 10. In addition, since the peripheral portion of the upper surface 50 of the tray 5 is provided with the peripheral wall portion 51, the waste in the bag 10 can be prevented from moving over the peripheral wall portion 51 to the outside of the tray 5. Therefore, in the toilet 1 of this embodiment, the waste on the bottom surface of the bag 10 can be prevented from moving outward beyond the tray 5, and a large downward load can be prevented from being applied to the mouth 100 of the bag 10.

[0136] In addition, in the tray 5 of this embodiment, the excrement in the bag 10 is guided to the front side, so when the operating part 150 is operated to move the movable part 151 to the front side, the pressure plate 154 is not easily loaded, and the rear surface of the bag 10 can be easily moved to the front side.

[0137] By opening the lid 6 and opening the side opening 2311, the tray 5 is exposed to the side (more specifically, the front) through the side opening 2311. The tray 5 can be taken in and out through the side opening 2311. When the side opening 2311 is closed by the lid 6, the tray 5 is not exposed towards the front of the toilet bowl 1. As shown in FIG. 7, when the side opening 2311 is in a position to close it, the tray 5 is covered from the front by the lid 6 and is not exposed to the front.

[0138] 2-1-13.Toilet lid As shown in Figures 1 and 10, the toilet lid 4 has a rectangular shape in a plan view when in the lying down position. When in the lying down position, the toilet lid 4 is a flat box shape with an open bottom. In this embodiment, the toilet lid 4 is a resin molded product. As shown in Figure 2, the toilet lid 4 is foldable, and when in the upright position, the toilet lid 4 stands up in the folded state on the toilet lid attachment portion 2520 of the rear wall 252 of the outer part 25 of the toilet body 2.

[0139] As shown in Fig. 1 and Fig. 12, the toilet lid 4 has a top wall portion 43 that covers the upper surface of the toilet seat 3, a front wall portion 440 that covers the front surface of the toilet seat 3, and a protruding portion 45 that protrudes from the front wall portion 440 so as to cover the recessed step portion S5. In this embodiment, the front wall portion 440 is a part of the peripheral wall portion 44 that extends downward from the outer periphery of the top wall portion 43 that is rectangular in plan view. The front wall portion 440 is a portion of the peripheral wall portion 44 that extends downward from the front edge of the top wall portion 43. The peripheral wall portion 44 further has a rear wall portion 441 that extends downward from the rear edge of the top wall portion 43, and a pair of left and right side wall portions 442 that extend downward from the left and right edges of the top wall portion 43.

[0140] 7 to 9, the front wall portion 440 is provided so that its front surface is aligned flush with the front surface of the front wall 251 of the outer part 25. The rear wall portion 441 is provided so that its rear surface is aligned flush with the rear surface of the rear wall 252 of the outer part 25. The pair of left and right side wall portions 442 are provided so that their outer left-right surfaces are aligned flush with the outer left-right surfaces of the pair of left and right side walls 253 of the outer part 25. The top surface of the top wall portion 43 is curved so that the center in the front-rear and left-right directions forms the uppermost portion, and the portion closer to the outer periphery is located lower.

[0141] As shown in Figures 1, 2, 8, and 10, the toilet lid 4 is foldable and is composed of a front part 40 and a rear part 41 that are rotatably connected. Each of the front part 40 and the rear part 41 is a flat box shape with an open bottom when in the lying down position. The rear end of the front part 40 and the front end of the rear part 41 are hingedly connected so as to rotate around an axis of rotation parallel to the left-right direction. When folded, the back surfaces of the front part 40 and the rear part 41 (i.e., the bottom surfaces when in the lying down position) face each other.

[0142] As shown in Figures 1 and 7, a protruding portion 45 protrudes downward from the left-right center of the front wall portion 440 of the front part 40 of the toilet lid 4. As shown in Figure 12, the front wall portion 440 and the protruding portion 45 have the same thickness in the front-to-rear direction. The protruding portion 45 fits into the opening 255 and the recessed portion 256 (i.e., the portion on the opening side of the recessed step portion S5) of the outer part 25 of the toilet body 2, and covers the underside of the front end portion of the toilet seat 3 from diagonally below and ahead.

[0143] As shown in Figures 1, 10, and 12, the top wall 43 of the toilet lid 4 is provided with a recess 420 recessed downward, and a flange 421 protruding from the edge of the upper opening of the recess 420 toward the center of the upper opening. The recess 420 and the flange 421 form a finger hook 42 on which fingers can be hooked when opening and closing the toilet lid 4. In this embodiment, the flange 421 is U-shaped and opens to the rear in a plan view. The recess 420 is semi-elliptical in a plan view.

[0144] A recess 420 and a U-shaped flange 421 are provided at the rear end of the top wall 43 of the front part 40 so as to be open toward the rear. In this embodiment, the recess 420 and the flange 421 are provided at the center in the left-right direction of the rear end of the top wall 43 of the front part 40. This makes it easier to form the recess 420 and the flange 421 when the front part 40 is resin molded.

[0145] By providing flange portion 421 in a U-shape that opens rearward in plan view, fingers can be hooked onto flange portion 421 from all directions except the rear, making it easier to operate toilet lid 4.

[0146] 2-2. Toilet handrails As shown in Figs. 4 and 25, the freestanding toilet handrail 8 includes a base 9 placed on the floor, and at least one handrail (three handrails 11, 12, and 13 in this embodiment) installed on the base 9.

[0147] At least one handrail includes a backrest handrail 11 that can support the back of a user seated on the toilet bowl 1, and armrest handrails 12, 13 that can support the elbows of a user seated on the toilet bowl 1.

[0148] The base 9 has a toilet installation section 90 on which the entire toilet 1 rests. The base 9 is plate-shaped. In this embodiment, the base 9 has a rectangular plate-shaped base body 91 made of a metal plate, and a rectangular frame-shaped edge section 92 attached to the outer periphery of the base body 91. The edge section 92 is made of, for example, rubber.

[0149] In this embodiment, the remaining portion of the base body 91, excluding the left and right ends, is the toilet installation portion 90. Handrails 11, 12, and 13 are provided on the left and right portions of the toilet installation portion 90 of the base body 91 (i.e., the left and right ends of the base body 91).

[0150] The backrest handrail 11 has a backrest main body 110 curved in a convex arc shape toward the rear, and a pair of left and right side parts 111 extending linearly forward from the left and right ends of the backrest main body 110. The backrest handrail 11 further has a pair of left and right support parts 112 that extend linearly in the vertical direction and are fixed to the base 9. The front ends of the pair of left and right side parts 111 are connected to the upper ends of the pair of left and right support parts 112.

[0151] Each of the pair of left and right support parts 112 has a columnar shape extending linearly in the vertical direction, a support main body part 113 to whose upper end part the side part 111 is connected, and a cylindrical tubular part 114 extending in the vertical direction, into which the support main body part 113 is inserted. Each of the pair of left and right support parts 112 further has a rectangular frame-shaped flange part 115 (see FIG. 17) extending horizontally from the lower end of the tubular part 114, and a cover 116 that covers the flange part 115.

[0152] Each of the pair of left and right support portions 112 is installed on the base 9 by fixing the flange portion 115 to the base body 91 of the base 9 with a plurality of fasteners 117 such as screws (see FIG. 17). The plurality of fasteners 117 and the flange portion 115 are covered with a cover 116.

[0153] The right-side elbow rest handrail 12 comprises an elbow rest main body 120 on which the elbow is placed, and a support column 121 that extends linearly in the vertical direction and is fixed to the base 9 to support the elbow rest main body 120. The support column 121 has a support column main body 122 that extends linearly in the vertical direction and has the elbow rest main body 120 fixed to its upper end, and a tube portion 123 that is tubular extending in the vertical direction and into which the support column main body 122 is inserted. The support column 121 further comprises a rectangular frame-shaped flange portion 124 that extends horizontally from the lower end of the tube portion 123, and a cover 125 that covers the flange portion 124.

[0154] The support portion 121 is installed on the base 9 by fixing the flange portion 124 to the base body 91 of the base 9 with a plurality of screws (not shown). The plurality of screws and the flange portion 124 are covered with a cover 125.

[0155] The elbow rest main body 120 is provided with an operating unit 126 for adjusting the height of the elbow rest handrail 12, and a slidable upper cover 127 that covers the operating unit 126. The upper cover 127 is slid forwards and backwards to expose the operating unit 126, and the operating unit 126 can be operated to lower the elbow rest handrail 12. The elbow rest handrail 12 can be lowered only when the operating unit 126 is pressed, and there is no need to operate the operating unit 126 when raising the elbow rest handrail 12. Note that the relationship between the operation of the operating unit 126 and the raising and lowering action of the elbow rest handrail 12 is not limited to the above.

[0156] The armrest handrail 12 can be lowered to a position where the top surface of the armrest body 120 is at approximately the same height as the top surface of the toilet seat 3 in the reclined position. Therefore, the armrest handrail 12 does not easily interfere with movement between the toilet seat 3 and its surroundings (e.g., a bed).

[0157] The left elbow rest handrail 13 has an elbow rest main body 130 and a support column 131 that supports the elbow rest main body 130. The support column 131 has a support section 132 that extends linearly in the front-to-rear direction, a curved section 133 that extends downward from the front end of the support section 132 in an arc shape that convexly extends forward, and a straight section 134 that extends linearly downward from the lower end of the curved section 133. The support column 131 further has a tube section 135 that is tubular extending vertically and into which the straight section 134 is inserted, a rectangular frame-shaped flange section 136 that extends horizontally from the lower end of the tube section 135, and a cover 137 that covers the flange section 136.

[0158] The support portion 131 is installed on the base 9 by fixing the flange portion 136 to the base body 91 of the base 9 with a plurality of screws (not shown). The plurality of screws and the flange portion 136 are covered with a cover 137.

[0159] The height of the left armrest handrail 13 can be adjusted by changing the fixed position of the straight portion 134 relative to the tubular portion 135. The tubular portion 135 and the straight portion 134 are fixed together with a fastener such as a screw.

[0160] In the toilet handrail 8 of the present embodiment described above, the toilet 1 is installed on the toilet installation portion 90 of the base 9, as shown in FIG.

[0161] The toilet 1 is installed so that the left and right recesses 2330 of the toilet body 2 of the toilet 1 are located between the support post 112 of the backrest handrail 11 and the support posts 121, 131 of the left and right armrest handrails 12, 13 in the front-rear direction. This makes it easy for the caregiver to insert their legs into the left and right recesses 2330.

[0162] In addition, the toilet 1 is installed on the toilet handrail 8 so that the front ends of the armrest handrails 12, 13 protrude further forward than the front end of the toilet 1. Therefore, when a user sitting on the toilet seat 3 grasps the front ends of the armrest handrails 12, 13 and stands up, it is easy to apply force, making it easier to stand up.

[0163] The toilet handrail 8 may have only the backrest handrail 11, or may have the backrest handrail 11 and only one of the left and right armrest handrails 12, 13.

[0164] 3. How to use the toilet An example of how to use the toilet 1 of this embodiment described above will now be described.

[0165] First, the user or caregiver (hereinafter referred to as "user, etc.") opens the toilet lid 4 and the toilet seat 3 (that is, in an upright position) to expose the upper opening 2400 of the toilet body 2 (see FIG. 2).

[0166] Next, the user etc. widens the mouth 100 of the bag 10 and attaches the mutually opposing first portion 100a and second portion 100b of the mouth 100 of the bag 10 to the first attachment portion 140 and second attachment portion 141 of the bag attachment portion 14, respectively (see FIG. 3). The bottom surface of the bag 10 with the mouth 100 attached to the bag attachment portion 14 is received by the receiving tray 5. At this time, it is preferable to insert a hand into the open mouth 100 of the bag 10 and spread the bag 10 so that the bottom surface of the bag 10 is aligned with the upper surface of the receiving tray 5.

[0167] Next, the user or the like pours a coagulant into the bag 10 to coagulate the liquid, and closes the toilet seat 3 (i.e., places it in a lying position). This makes the toilet 1 ready for use, allowing the user to sit on the toilet seat 3 and relieve themselves.

[0168] After the user has completed excretion, the user closes the toilet lid 4. Subsequent tasks can be performed with the toilet lid 4 closed.

[0169] Next, the user or the like grasps the operating part 150 of the sealing device 15 and pulls it out from the storage position to the front end position. As a result, the movable part 151 connected to the operating part 150 moves forward, and the second part 100b on the rear side of the mouth 100 of the bag 10 attached to the second attachment part 141 on the movable part 151 approaches the first part 100a (the front part) of the mouth 100 of the bag 10. At this time, the part between the first part 100a and the second part 100b of the mouth 100 of the bag 10 is pushed inward in the left-right direction by the pressing device 155 of the sealing device 15 and is sandwiched between the first part 100a and the second part 100b. At this time, the rear surface of the bag 10 is pushed forward by the pressing plate 154 connected to the movable part 151, and not only the mouth 100 but the entire bag 10 moves forward.

[0170] Next, the user or the like grasps operating part 150 of sealing device 15, rotates it from the front end position to the sealing position, and waits at the sealing position for a predetermined time (about several seconds). As a result, the first part 100a and the slightly lower part of second part 100b of mouth 100 of bag 10 are melted by the heat of thermocompression part 153 that is activated while being sandwiched between pressing surface 1510 of movable part 151 and thermocompression part 153, and mouth 100 of bag 10 is sealed.

[0171] Next, the user or the like grasps the operating part 150 of the sealing device 15, rotates it from the sealing position to the front end position, and returns it from the front end position to the storage position. This causes the movable part 151 connected to the operating part 150 to move rearward, and the second part 100b of the mouth 100 of the sealed bag 10 is released from the second attachment part 141 on the movable part 151. Therefore, the mouth 100 of the sealed bag 10 is attached only to the first attachment part 140.

[0172] Next, the user or the like opens the toilet seat 3 to open the top opening 2400, and removes the first portion 100a of the mouth 100 of the bag 10 from the first attachment portion 140. The sealed corner bag 10 removed from the first attachment portion 140 is placed on the tray 5. At this time, the sealed bag 10 may be removed upward from the top opening 2400 and discarded, etc.

[0173] Next, the user or the like removes the tray 5 with the sealed bag 10 on it to the outside through the side opening 2311, and discards the sealed bag 10. At this time, if the tray 5 is dirty, it can be washed. Next, the user or the like inserts the tray 5 through the side opening 2311, and places the tray 5 in its original position. Next, the user or the like closes the side opening 2311 with the lid 6.

[0174] Next, the user opens the toilet lid 4 and the toilet seat 3, and attaches the mouth 100 of the new bag 10 to the bag attachment portion 14 in the same manner as described above.

[0175] 4. Effects In the toilet 1 of this embodiment described above, when carrying the toilet 1 in an unfixed state to the base 9 of the toilet handrail 8, it can be carried by hooking one's fingers on the unevenness 2332 of the finger hook surface 2331 above the left and right recesses 2330 of the toilet body 2.

[0176] Therefore, in the toilet 1 of this embodiment, fingers can be easily hooked onto the finger hook surface 2331, improving the portability of the toilet 1.

[0177] Furthermore, in the toilet 1 of this embodiment, the recess 2330 extends to the lower ends of both sides of the toilet body 2 and is open downward, making it easier to insert a finger into the recess 2330 even without visual inspection, compared to a case in which the recess 2330 is provided short on a portion of the vertical direction of both sides of the toilet body 2.

[0178] Furthermore, in the toilet 1 of this embodiment, the recess 2330 is open facing downwards, so dust is less likely to accumulate within the recess 2330, and the recess 2330 is also easy to clean.

[0179] Furthermore, in the toilet 1 of this embodiment, the recess 2330 extends to the bottom ends of both sides of the toilet body 2, making it less obvious that the recess 2330 is a structure for hooking fingers, compared to when the recess 2330 is provided short on part of the vertical direction of both sides of the toilet body 2. Therefore, in the toilet 1 of this embodiment, portability can be improved in addition to an improved appearance.

[0180] Furthermore, in the toilet 1 of this embodiment, the unevenness 2332 is provided on the finger hook surface 2331 in the center in the front-to-rear direction of the toilet body 2, so that the toilet 1 can be carried in a well-balanced manner by hooking fingers on the unevenness 2332. Furthermore, in the toilet 1 of this embodiment, hooking fingers on the unevenness 2332 supports the center in the front-to-rear direction of the toilet body 2 (i.e. the center of gravity of the toilet 1), making it easy to balance the toilet 1 intuitively.

[0181] In addition, in the toilet 1 of this embodiment, the unevenness 2332 is composed of multiple protrusions 2333 that extend in the front-to-back direction and are spaced apart in the left-to-right direction, making it easy to hook fingers on the unevenness 2332 in both the front-to-back and left-to-right directions.

[0182] Furthermore, in the toilet 1 of this embodiment, the length of the multiple protrusions 2333 in the front-to-rear direction is between 20 mm and 40 mm, so that multiple fingers can be hooked onto the multiple protrusions 2333, making it easy to achieve an anti-slip effect.

[0183] Furthermore, in the toilet 1 of this embodiment, the unevenness 2332 is provided on the finger hook surface 2331 facing downward, so the unevenness 2332 is less noticeable and the deterioration of the appearance of the toilet 1 is easily prevented.

[0185] The recess 2330 is not limited to one that extends to the lower end of the toilet body 2 and is open downward. The recess 2330 only needs to be large enough to allow a finger to be inserted, and may be open only outward in the left-right direction.

[0186] The unevenness 2332 does not have to be provided in the center of the finger hook surface 2331 in the front-rear direction of the toilet body 2, and may be provided, for example, over the entire length of the finger hook surface 2331 in the front-rear direction.

[0187] The unevenness 2332 does not have to be formed of a plurality of protrusions 2333 extending in the front-rear direction and arranged at intervals in the left-right direction, and may have other unevenness structures. For example, the unevenness 2332 may be a plurality of grooves provided on the finger hook surface 2331. The unevenness 2332 may also be formed of a plurality of point-like protrusions or a plurality of point-like depressions. The unevenness 2332 may also be formed of a combination of the above-mentioned modified examples.

[0188] The length of each of the multiple protrusions 2333 in the front-rear direction is not limited to 20 mm or more and 40 mm or less, and may be outside this range. Furthermore, the length of each of the multiple protrusions 2333 in the front-rear direction may be different from one another. Furthermore, each of the multiple protrusions 2333 may be composed of multiple projections arranged in a row at intervals.

[0189] Furthermore, the toilet 1 is not limited to the structure shown in Figures 2, 4, etc. For example, the toilet 1 can be provided with a bucket container 19 instead of the sealing unit 18, as in the modified toilet 1 shown in Figure 26. The bucket container 19 has a bowl 190 that is provided integrally with the upper opening 2400 of the inner part 24 of the toilet body 2, and a bucket (not shown) that is detachably installed in the bowl 190. The user's waste is received in the bucket.

[0190] Furthermore, the toilet 1 is not limited to a non-flush toilet, but may be a movable flush toilet. Examples of movable flush toilets include a toilet connected to a water supply hose and a waste discharge hose, or a toilet with a flush water storage tank and a waste storage tank.

[0191] Furthermore, the toilet 1 is not limited to being fixed to the toilet handrail 8 and may be used alone. In this case, the toilet 1 may have a backrest and armrests that are provided integrally with the toilet body 2.

[0192] Furthermore, the external shapes of the toilet body 2 and the toilet lid 4 in the lying down position of the toilet 1 do not have to be cubic, and may be other shapes.

[0193] (summary) As described above in the embodiment and its modified example, the toilet (1) of the first aspect has the following configuration.
