The lower end of the right side wall 14 is joined to the right end of the floor 17, and the right side wall 14 is erected on the right end of the floor 17.

[0029] The rear wall 11 has an opening and a door 16, such as a hinged door, a sliding door, or a double sliding door, installed in the opening. The upper part of the deck 30 can be accessed from inside the sauna room 10 through the door 16. Note that a fixture other than a door, such as a sliding window, may be installed in the opening of the rear wall 11 instead of the door 16.

[0030] The sauna room 10 is also equipped with a heating device (not shown) that heats the air inside the sauna room 10. The heating device is provided, for example, on the front end surface of the sauna room 10. A window 110 is also installed on the right side wall 14 of the sauna room 10.

[0031] The changing room 20 has a floor on its bottom surface, a rear wall 21 on its rear surface, a right side wall 24 on its right side surface, a front wall 23 on its front surface, a left side wall on its left side surface, and a roof 25 on its top surface. The floor of the changing room 20 is installed on a base frame 62 laid on a stand 3. The lower end of the rear wall 21 is joined to the rear end of the floor, and the rear wall 21 is erected at the rear end of the floor.

[0033] The roofs 15, 25 of the sauna room 10 and the changing room 20 are single-pitch roofs that slope downward to the right or left. The roofs 15, 25 may not be single-pitch roofs, but may be flat roofs or gable roofs. If the roofs 15, 25 are gable roofs, the ridges of the roofs 15, 25 extend forward and backward or left and right. The eaves and ridge overhangs of the roofs 15, 25 are very short.

[0034] The tarp 40 is stretched between the rear of the sauna room 10 and the front of the changing room 20 above the deck 30. The tarp 40 is a waterproof membrane material, so it prevents water from passing through. The tarp 40 is water-repellent. In one example, the water-repellent properties of the tarp 40 are achieved by applying a silicone-based or fluorine-based water-repellent agent to the tarp 40. In another example, the water-repellent properties of the tarp 40 are achieved by having the surface of the tarp 40 have fine irregularities.

[0035] (underfloor structure) FIG. 2(a) is a plan view showing the underfloor structure of the sauna room 10, the changing room 20, and the deck 30 laid on the frame 3 of the chassis 2. FIG. 2(b) is a side view showing the underfloor structure of the sauna room 10, the changing room 20, and the deck 30 laid on the frame 3 of the chassis 2. In FIG. 2(a), L1 indicates the outer wall line of the sauna room 10, L2 indicates the outer wall line of the changing room 20, L3 indicates the outer perimeter line of the deck 30, and L4 indicates the outer perimeter line of the frame 3. As shown in FIG. 2(a) and (b), a base frame 61 which is the foundation of the sauna room 10, a base frame 62 which is the foundation of the changing room 20, and a floor lower part 63 of the deck 30 are attached to the frame 3. In addition, four twist locks 31 (see FIG. 5) for attaching the sauna room 10 are provided on the front side of the frame 3, and four twist locks 31 for attaching the changing room 20 are provided on the rear side.

[0036] The base frame 61 is configured to include a short-side frame member 61a that is long along the short side direction of the sauna room 10, and long-side frame members 61b, 61c that are long along the long side direction of the sauna room 10. In this embodiment, the short-side frame member 61a and the long-side frame member 61b are, for example, wood. By making the short-side frame member 61a and the long-side frame member 61b out of wood, the weight of the base frame 61 can be reduced. The long-side frame member 61c located at the front end of the chassis 2 is a steel frame, and pipes extending from the sauna room 10 or steel brackets supporting the pipes are fixed thereto by welding. By making the long-side frame member 61c out of steel, the width can be made narrower than wood, making it easier to secure space for arranging the pipes or brackets, and making it possible to fix the pipes or brackets by welding. Furthermore, by providing this steel long side frame member 61c at the front end of the chassis 2 (that is, providing the piping at the front end of the chassis 2), the workability of the piping work can be improved and safety during driving on the road can be ensured. The materials of the short-side frame material 61a and the long-side frame materials 61b and 61c are not limited to those mentioned above.

[0037] A wooden floor beam fixing metal fitting 61d is joined to both ends of each of the short-side frame material 61a and the long-side frame material 61b, and a joint metal fitting 61e is rigidly joined to the other end of each of the wooden floor beam fixing metal fittings 61d by bolts, welding, or the like. That is, the short-side frame material 61a and the long-side frame material 61b are connected via the wooden floor beam fixing metal fitting 61d and the joint metal fitting 61e. In addition, the joint metal fitting 61e joined to the short-side frame material 61a is joined to both ends of the long-side frame material 61c. That is, the short-side frame material 61a and the long-side frame material 61c are connected via the wooden floor beam fixing metal fitting 61d and the joint metal fitting 61e. As a result, the base frame 61 forms a rectangular frame body with the joint metal fittings 61e at the four corners. In addition, the short-side frame material 61a and the long-side frame materials 61b and 61c are bolted to the frame 3 as necessary, so that a plurality of through holes for bolts are formed.

[0038] Fig. 3 is a diagram mainly explaining the configuration of the joint metal 61e (62e), (a) being a side view and (b) being a cross-sectional view. Fig. 3(a) and (b) show the right rear joint metal 61e (62e) as an example. The joint metal 61e is a rectangular box with one side open. As shown in Fig. 3(a), the inside of the joint metal 61e is divided into two spaces, and a square tube member 611 is disposed in one space. In addition, in the other space, members such as bolts are inserted through the opening of the joint metal 61e, or hands, tools, etc. are inserted during the assembly work of the sauna room 10, etc.

[0039] The square tube member 611 is used when loading and unloading the sauna room 10 onto the chassis 2 or the like using a jack device. Specifically, for example, one end of a rod-shaped member is inserted into the square tube member 611 at each of the multiple joint metal fittings 61e of the base frame 61, and the other end of each rod-shaped member is lifted with a jack device, thereby jacking up the sauna room 10. This makes it possible to lift the sauna room 10 with a jack device even in a situation where it is not possible to place a jack device directly under the sauna room 10.

[0040] As shown in Fig. 3(a), the joint metal 61e is positioned so that the opening of the joint metal 61e faces outward (the side surface of the chassis 2) and the square tube member 611 is positioned on the short-side frame member 61a side. An upper circular hole 612 is formed in the upper surface of the joint metal 61e, penetrating the upper surface. A stud bolt 56 that connects the base frame 61 and the sauna room 10 body is passed through this upper circular hole 612. The stud bolt 56 is fixed by a nut 56a and a nut 56b.

[0041] As shown in Fig. 3(b), a long hole 613 is formed in the underside of the joint metal 61e, penetrating the underside. This long hole 613 is used when attaching the sauna room 10 to the stand 3 of the chassis 2 by inserting the protrusion of the twist lock 31 provided on the stand 3 (see Fig. 5). When attaching the sauna room 10 to the frame 3, first, the sauna room 10 is hoisted by a crane or the like (or lifted up by a jack device or the like) and placed on the frame 3 with the positions of the multiple long holes 613 of the sauna room 10 aligned with the positions of the multiple twist locks 31 provided on the frame 3. After that, the protrusions of the twist locks 31 inserted into the long holes 613 are rotated to switch the twist locks 31 from the released state to the fixed state. By performing this switching operation for each of the multiple twist locks 31, the sauna room 10 can be fixed to the frame 3. In addition, a lower circular hole 614 that penetrates the lower surface of the joining hardware 61e is formed, and a nut 614a is fixed by welding or the like to the inside of the joining hardware 61e (the upper surface of the lower surface of the joining hardware 61e) at a position corresponding to the lower circular hole 614.

[0042] The base frame 62 is configured to include short-side frame members 62a that are long along the short side direction of the sauna room 10, and long-side frame members 62b that are long along the long side direction of the sauna room 10. In this embodiment, the short-side frame members 62a and the long-side frame members 62b are made of wood, for example. By making the short-side frame members 62a and the long-side frame members 62b out of wood, the weight of the base frame 61 can be reduced. Note that the materials of the short-side frame members 62a and the long-side frame members 62b are not limited to those mentioned above.

[0043] A wooden floor beam fixing metal fitting 62d is joined to both ends of each of the short-side frame material 62a and the long-side frame material 62b, and a joint metal fitting 62e is rigidly joined to the other end of each of the wooden floor beam fixing metal fittings 62d by bolts, welding, or the like. That is, the short-side frame material 62a and the long-side frame material 62b are connected via the wooden floor beam fixing metal fittings 62d and the joint metal fittings 62e. This forms a rectangular frame body with the joint metal fittings 62e at the four corners of the base frame 62. Note that the short-side frame material 62a and the long-side frame material 62b are bolted to the frame 3 as necessary, so multiple through holes for bolts are formed.

[0044] The joint metal 62e is a rectangular box with one side open. As shown in Fig. 3(a), the inside of the joint metal 62e is divided into two spaces, and a square tube member 621 is disposed in one space. In addition, in the other space, members such as bolts are inserted through the opening of the joint metal 62e, or hands, tools, etc. are inserted during the assembly work of the dressing room 20, etc.

[0045] The square tube member 621 is used when loading and unloading the changing room 20 onto the chassis 2, etc., using a jack device. Loading and unloading the changing room 20 onto the chassis 2, etc. is similar to loading and unloading the sauna room 10 onto the chassis 2, etc., described above, except that the square tube member 621 is used instead of the square tube member 611, so the same explanation will be used.

[0046] As shown in Fig. 3(a), the joint metal 62e is arranged so that the opening of the joint metal 62e faces outward (the side surface of the chassis 2) and the square tube member 621 is located on the short-side frame material 62a side. An upper circular hole 622 is formed in the upper surface of the joint metal 62e, penetrating the upper surface. A stud bolt 56 that connects the base frame 62 and the changing room 20 is passed through this upper circular hole 622. The stud bolt 56 is fixed by a nut 56a and a nut 56b.

[0047] 3(b), a long hole 623 is formed in the lower surface of the joint metal 62e, penetrating the lower surface. This long hole 623 is used when attaching the changing room 20 to the stand 3 of the chassis 2 by inserting a protrusion of a twist lock 31 provided on the stand 3. The method of attaching the changing room 20 to the frame 3 is the same as the explanation of the method of attaching the sauna room 10 to the frame 3 described above, except that the long hole 623 is used instead of the long hole 613, so the explanation will be used here. In addition, a lower circular hole 624 that penetrates the lower surface of the joining hardware 62e is formed, and a nut 624a is fixed by welding or the like to the inside of the joining hardware 62e (the upper surface of the lower surface of the joining hardware 62e) at a position corresponding to the lower circular hole 624.

[0048] As shown in FIG. 2(a), the underfloor 63 of the deck 30 is configured by bridging a plurality of joists 63b perpendicular to the joists 63a on a plurality of joists 63a. The joists 63a and joists 63b are made of, for example, steel. The joists 63a and joists 63b are fixed to the frame 3 with bolts or the like. As shown in FIG. 2(b), a floor material 63c of the deck 30 is laid on the joists 63b. The floor material 63c of the deck 30 has drainage holes (not shown). A decorative panel 63d is attached to the side of the deck 30.

Fig. 5 is a vertical cross-sectional view of the vicinity of the front end portion of the lower part of the sauna room 10 (near AA in Fig. 2(a)). As shown in FIG. 5, a floor 17 and a half base 18 are provided on the base frame 61 of the sauna room 10. The half base 18 is, for example, a square timber, and is provided on the periphery of the floor 17. Pillars 87 (see FIG. 2(b) and FIG. 3(a)) are arranged at the four corners of the floor 17 and the half base 18, and the rear wall 11, the left side wall 12, the front wall 13, and the right side wall 14 are respectively fastened with screws or bolts between adjacent pillars 87. Each pillar 87 is in contact with a vertical frame of an adjacent wall, and the vertical frame is fastened with screws or bolts. In addition, a connecting metal piece 88 is provided at the bottom of each pillar 87. The connecting metal piece 88 is a rectangular box shape with open sides, and has a through hole 88a on the bottom surface. The stud bolt 56 mentioned above is inserted through the through hole 88a from the upper circular hole 612 of the joint metal fitting 61e and penetrates the joint between the floor 17 and the half base 18, and the upper end of the stud bolt 56 is fixed by a nut 56b. In this way, the sauna room 10 body (the part above the floor 17) is fixed to the base frame 61. In the following description, the inner surfaces of the rear wall 11, the left side wall 12, the front wall 13, and the right side wall 14 on the inside of the sauna room 10 are collectively referred to as inner walls 19.

[0050] As shown in Fig. 5, a plurality of plywood panels 71-73, a roof drain 74, a foam insulation material 75, etc. are arranged on the floor 17 to form a water gradient. A floor finishing material 76 is laminated on the plywood 71. For example, sour roll can be used as the floor finishing material 76. A waterproof sheet 77 such as PVC is attached from the lower surface of the floor finishing material 76 to the lower part of the inner wall 19, and the lower end of a moisture-proof sheet 81 is overlapped on the upper end of the waterproof sheet 77 and joined with acrylic tape or the like.

[0051] As shown in Figs. 4 and 5, inside the sauna room 10, a moisture-proof sheet 81 is attached from the inner wall 19 to the ceiling. For example, a polyethylene sheet or the like can be used as the moisture-proof sheet 81. A sauna wall finishing material 83 is attached to the surface of the moisture-proof sheet 81 on the inner wall 19 side via vertical furring strips 82, and a ventilation layer is formed between the moisture-proof sheet 81 on the inner wall 19 side and the wall finishing material 83. A sauna ceiling finishing material 84 is attached to the surface of the moisture-proof sheet 81 on the ceiling side. At the joint between the wall and the ceiling (the joint between the wall finishing material 83 and the ceiling finishing material 84), the upper end of the wall finishing material 83 is spaced from the moisture-proof sheet 81 on the ceiling side, and the side end of the ceiling finishing material 84 is spaced from the upper end of the wall finishing material 83. As a result, an air vent (first air vent) that serves as an outlet for air that has passed between the moisture-proof sheet 81 on the inner wall 19 side and the wall finishing material 83 is formed between the upper end of the wall finishing material 83 and the side end of the ceiling finishing material 84. In addition, the lower end of the wall finishing material 83 is disposed with a gap between it and the floor finishing material 76. As a result, an air vent (second air vent) that serves as an inlet for air to the ventilation layer is formed between the lower end of the wall finishing material 83 and the floor finishing material 76. The above ventilation structure is designed to avoid the sash of the window 110 and the sash of the door 16.

[0052] As shown in FIG. 4, a joist 85 is provided at the edge of the inner wall 19 of the ceiling. A base plate 86 to which a ceiling finishing material 84 is fixed is attached to the underside of the joist 85. The side end of the base plate 86 is disposed with a gap between it and the inner wall 19, and the moisture-proof sheet 81 is attached across the inner wall 19, the underside of the joist 85, the side end face of the base plate 86, and the underside of the base plate 86. The position of the side end of the ceiling finishing material 84 and the position of the side end of the base plate 86 are aligned, so that a groove G with the moisture-proof sheet 81 attached is formed at the interface between the inner wall 19 and the ceiling, and the upper end of the wall finishing material 83 is disposed in this groove G. Here, as shown in Figure 6, it is possible to place the moisture-proof sheet 81 directly from the inner wall 19 to the underside of the base board material 86 without providing a groove G, but by providing a groove G at the joint between the inner wall 19 and the ceiling as shown in Figure 4, the moisture-proof sheet 81 becomes less visible to people inside the sauna room 10, thereby improving the appearance.

[0053] 7, the side edges of the base board material 86 to which the moisture-proof sheet 81 is attached and the ceiling finishing material 84 may be in contact with the inner wall 19, and the upper end of the wall finishing material 83 may be lowered to leave a gap between it and the ceiling finishing material 84, thereby forming an air vent (first air vent) that serves as an exit for air that has passed between the moisture-proof sheet 81 on the inner wall 19 side and the wall finishing material 83. Even in this way, the moisture-proof sheet 81 is less visible to people inside the sauna room 10, improving its appearance.

[0054] The ventilation structure described above allows air to circulate inside the sauna room 10 without stagnating along the walls. In addition, the wall side of the ventilation layer is covered with a moisture-proof sheet 81, improving moisture resistance and preventing damage to the walls of the sauna room 10 (rear wall 11, left side wall 12, front wall 13, right side wall 14) caused by moisture in the air passing through the ventilation layer.

[0055] (Modified chassis) Conventionally, a chassis is provided with twist locks at the four corners of the frame to prevent cargo such as containers and residential units from moving. However, simply fixing the four corners with twist locks is problematic in terms of structure and durability when carrying two independent cargos (such as residential units) as in the above embodiment. Therefore, in the above embodiment, the chassis 2 is provided with four twist locks 31 for attaching the sauna room 10 and four twist locks 31 for attaching the changing room 20. The configuration of the chassis 2 is not particularly limited as long as it is provided with a total of eight twist locks 31 as described above, but for example, the configuration of the chassis 2A shown in FIG. 8 may be applied.

[0056] Fig. 8(a) is a plan view of the chassis 2A, and Fig. 8(b) is a side view of the chassis 2A. As shown in Figs. 8(a) and (b), the chassis 2A is configured to include a coupling part 91 for coupling with a towing vehicle, a platform 92 for placing a load, and wheels 93. The platform 92 corresponds to the platform 3 in the chassis 2 shown in Fig. 1, and the wheels 93 correspond to the wheels 4 in the chassis 2 shown in Fig. 1.

[0057] The stand 92 is configured to include a plurality of long-side frame members 92a extending in the front-rear direction of the chassis 2A, and a plurality of short-side frames 92b extending in the left-right direction of the chassis 2A. The stand 92 is also provided with four sets of support members 92e-92h spanning the left and right sides, and twist locks 94 are attached to both ends of each. The support member 92e is provided at the front end of the stand 92. The support member 92f is provided at a position corresponding to the length of the side of a unit (e.g., sauna room 10) placed on the front side of the stand 92. The support member 92h is provided at the rear end of the stand 92. The support member 92g is provided at a position corresponding to the length of the side of a unit (e.g., changing room 20) placed on the rear side of the stand 92.

[0058] The support members 92e to 92g are, for example, rectangular steel tubes, and include members 921e to 921h that bridge between two sets of long-side frame members 92a in the center of the frame 92, and members 922e to 922g to which twist locks 94 are attached at both ends. Each twist lock 94 has a protrusion 94a and a base 94b, and the base 94b is attached to the members 922e to 922h via flat steel 95. The twist lock 94 attached to the member 922e has a front end joined to the short-side frame 92b on the front end side of the frame 92. The twist lock 94 attached to the member 922h has a rear end joined to the short-side frame 92b on the rear end side of the frame 92. Support members 96 extending in the front-rear direction of the stand 92 are attached to the rear side of the connection part between the member 922e and the flat steel 95 attached thereto, the front side of the connection part between the member 922h and the flat steel 95 attached thereto, both front and rear sides of the connection part between the member 922f and the flat steel 95 attached thereto, and both front and rear ends of the connection part between the member 922g and the flat steel 95 attached thereto. A support member 97 is attached to each support member 96 at a right angle to the extension direction, and the end of each support member 97 on the opposite side to the support member 96 is attached to the outer long side frame material 92a of the stand 92. That is, each twist lock 94 is supported by the support members 92e to 92g, and is supported by the outer long side frame material 92a via the support members 96 and 97. This allows two independent loads (such as residential units) to be placed on the stand 92 without any problems in terms of structure and durability. The support member 96 is, for example, a square steel tube, and the support member 97 is, for example, an L-shaped steel tube.

[0059] In addition, the outer long-side frame member 92a is cut between the connection portions between the two support members 97 located on both sides of the twist locks 94 (twist locks 94 supported by members 921f and 921g) provided at the corners other than the four corners of the frame 92, forming an opening. This opening allows easy access to the twist locks 94 from the side of the frame 92, making it easy to check, for example, whether the protrusions 94a are fixed in a direction that will not cause them to come off the load placed on the frame 92. In addition, this opening allows easy access to the inside of the joint metal fittings 61e when the sauna room 10 described above is placed on the frame 92, making it easy to install the sauna room 10, such as by attaching the stud bolts 56.
