As shown in fig. 1, the base 110 of the embodiment includes a first structural body part 111. As will be described later, the base 110 may also include a second structural member 112.

The first structural part 111 includes a first tube part 11P and a first cross tube part 11 XP. The first pipe portion 11P includes a first region 11, a first facing region 11c, and a first opening 11 o. The first pipe portion 11P extends in the first direction D1.

The first cross pipe portion 11XP includes a first cross region 11X, a first cross facing region 11Xc, and a first cross opening 11 Xo. The first cross tube portion 11XP extends in the second direction D2. The second direction D2 intersects the first direction D1. The second direction D2 is, for example, perpendicular to the first direction D1.

In one example, the first tube portion 11P and the first cross tube portion 11XP have, for example, a square tube shape. The first tube part 11P and the first cross tube part 11XP may be, for example, circular tube-shaped. The cross-sectional shape of the first pipe portion 11P (for example, the cross-sectional shape when cut along a plane perpendicular to the first direction D1) is arbitrary. The cross-sectional shape (for example, the cross-sectional shape when cut along a plane perpendicular to the second direction D2) of the first cross tube portion 11XP is arbitrary.

As shown in fig. 1(a) and 3, in this example, the first pipe portion 11P includes a first side region 11S and a first opposite side region 11 Sc. The direction from the first side region 11S to the first opposite side region 11Sc is along the third direction D3. The third direction D3 intersects a plane including the first direction D1 and the second direction D2.

As shown in fig. 1(b) and 3, in this example, the first cross-pipe portion 11XP includes a first cross-side region 11XS and a first cross-opposite side region 11 XSc. The direction from the first cross-side region 11XS to the first cross-opposite-side region 11XSc is along the third direction D3.

As shown in fig. 2(a) and 2(b), the first cross pipe portion 11XP extends in the second direction D2 and is connected to the first section 11 of the first pipe portion 11P. For example, the first cross section 11X of the first cross pipe portion 11XP is connected to the first connection portion 11cp of the first section 11. As shown in fig. 2(b), in this example, the first region 11 includes a first hole 11 HL. The first tube part 11P and the first cross tube part 11XP are connected to each other through the first hole 11 HL.

As shown in fig. 1(a), the position of the first region 11 in the second direction D2 is between the position of the first intersection opening 11Xo in the second direction D2 and the position of the first opposing region 11c in the second direction D2. As shown in fig. 2(a) and 2(b), the position of the first intersection region 11X in the first direction D1 is between the position of the first opening 11o in the first direction D1 and the position of the first intersection opposing region 11Xc in the first direction D1. In one example, the first intersection area 11X is connected to the first connection portion 11cp of the first area 11.

As shown in fig. 2(a), 2(b), and 3, a distance along the first direction D1 between the first opening 11o and the first intersection region 11X is set to a distance L1. The distance L1 corresponds to the distance between the first opening portion 11o and the first connecting portion 11cp along the first direction D1. A distance between the first intersection opening 11Xo and the first region 11 along the second direction D2 is set to a distance L2. Distance L1 is shorter than distance L2.

As will be described later, a frame of furniture can be inserted into the first pipe portion 11P. The frame can be inserted into the first cross tube part 11 XP. As described above, the distance L2 is longer than the distance L1. In the state shown in fig. 1(a), when the frame is inserted into the first pipe portion 11P, the second height of the frame corresponds to the distance L2 with respect to the floor surface. In the state shown in fig. 1(b), when the frame is inserted into the first cross tube portion 11XP, the first height of the frame corresponds to the distance L1 with respect to the floor surface. In this example, the second height is higher than the first height. By inserting the frame into the first tube section 11P or the first cross tube section 11XP, the height of the frame can be easily changed, and the height of the bed can be easily changed. According to the embodiment, a convenient base and a bed device can be provided.

As described above, the first structural body part 111 includes the first wall portion 11A, the first opposing wall portion 11Ac, the first region 11, and the first intersection region 11X. The first region 11 is disposed between the first wall portion 11A and the first opposing wall portion 11 Ac. The first region 11 extends in a first direction D1. The first intersection region 11X is disposed between the first wall portion 11A and the first opposing wall portion 11 Ac. The first intersection region 11X extends in a second direction D2 intersecting the first direction D1. The third direction D3 from the first wall portion 11A to the first opposing wall portion 11Ac intersects a plane including the first direction D1 and the second direction D2. The height of the frame of the piece of furniture when placed in the first region 11 between the first wall portion 11A and the first opposite wall portion 11Ac is different from the height of the frame when placed in the first intersection region 11X between the first wall portion 11A and the first opposite wall portion 11 Ac.

As described above, the first structural body part 111 may further include the first opposing region 11c and the first intersecting opposing region 11 Xc. The direction from the first region 11 to the first opposing region 11c is along the second direction D2. The direction from the first intersecting region 11X to the first intersecting opposite region 11Xc is along the first direction D1. When the frame is placed in the first area 11, the frame is between the first area 11 and the first opposing area 11 c. When the frame is placed at the first crossing region 11X, the frame is between the first crossing region 11X and the first crossing opposite region 11 Xc.

As shown in fig. 1(a), the distance between the first region 11 and the first opposing region 11c along the second direction D2 is set to a distance Ls 2. As shown in fig. 1(b), the distance along the second direction D2 between the first intersection region 11X and the first intersection opposing region 11Xc is set as a distance Ls 1. In an embodiment, distance Ls2 is substantially the same as distance Ls 1. In one state, the frame is inserted between the first region 11 and the first opposing region 11 c. In another state, the frame is inserted between the first intersection region 11X and the first intersection opposing region 11 Xc. In these states, the frame is stably inserted, and positional deviation can be suppressed.

As shown in fig. 2(a) and 2(b), the first region 11 is continuous with the first intersection opposing region 11 Xc. The first region 11 comprises at least one first hole 11 HL. The inner space of the first pipe part 11P is connected to the inner space of the first cross pipe part 11XP via the first hole 11 HL. For example, when the first structural body part 111 is cleaned, it is easily dried. It is easy to provide a clean base 110.

As shown in fig. 1(a) and 3, the first structural body part 111 may also include a first wall portion 11A and a first opposing wall portion 11 Ac. The direction from the first wall portion 11A to the first opposite wall portion 11Ac is along the third direction D3. The direction from the first wall portion 11A to the first side region 11S and the direction from the first opposing wall portion 11Ac to the first opposing side region 11Sc are along the second direction D2.

As shown in fig. 3, the direction from the first wall portion 11A to the first intersecting side region 11XS and the direction from the first opposing wall portion 11Ac to the first intersecting opposing side region 11XSc are along the first direction D1.

By providing the first wall portion 11A and the first opposing wall portion 11Ac, the load of the frame can be dispersed when the frame is inserted into the first pipe portion 11P and when the frame is inserted into the first cross pipe portion 11 XP. The frame can be stably supported.

The first wall portion 11A and the first opposing wall portion 11Ac may be continuous with the first pipe portion 11P. The first wall portion 11A and the first opposing wall portion 11Ac may be continuous with the first cross tube portion 11 XP.

As shown in fig. 1(a), the first structural body part 111 may also include a second wall portion 11B. The second wall portion 11B corresponds to a portion protruding sideward from the frame. As shown in fig. 1(a), the position of the first opposite-side region 11Sc in the third direction D3 is between the position of the first side region 11S in the third direction D3 and the position of the second wall portion 11B in the third direction D3.

As shown in fig. 1(B), the position of the first intersecting opposite side region 11XSc in the third direction D3 is between the position of the first intersecting side region 11XS in the third direction D3 and the position of the second wall portion 11B in the third direction D3.

By providing the second wall portion 11B, for example, the contact area between the first structural part 111 and the floor can be increased when the frame is inserted into the first pipe portion 11P and when the frame is inserted into the first cross pipe portion 11 XP. More stable support can be performed.

As shown in fig. 1(b), the first structural body part 111 may also include a third wall portion 11C. The position of the first intersecting opposing region 11Xc in the first direction D1 is between the position of the first intersecting region 11X in the first direction D1 and the position of the third wall portion 11C in the first direction D1.

By providing the third wall part 11C, in the case of inserting the frame into the first pipe part 11P, for example, the contact area of the first structural body part 111 and the floor can be increased. More stable support can be performed.

As shown in fig. 2(b), 5(a) and 5(b), the first structural body part 111 may further include a first inclined wall portion 11 ia. The first inclined wall portion 11ia is continuous with the second wall portion 11B and the third wall portion 11C. The first inclined wall portion 11ia is inclined with respect to the first direction D1 and inclined with respect to the third direction D3.

By providing the first inclined wall portion 11ia, the corner portion becomes rounded, and damage or the like is less likely to occur. Between the first inclined wall portion 11ia and the second wall portion 11B, the angle of inclination may vary continuously or discontinuously. Between the first inclined wall portion 11ia and the third wall portion 11C, the angle of inclination may be continuously changed or may be discontinuously changed.

As shown in fig. 1(a), 3, 4(a) and 4(b), the first structural body part 111 may also include a second inclined wall portion 11 ib. The second inclined wall portion 11ib is continuous with the first opposing region 11c and the second wall portion 11B. The second inclined wall portion 11ib is inclined with respect to the second direction D2 and is inclined with respect to the third direction D3.

By providing the second inclined wall portion 11ib, the corner portion becomes rounded, and damage or the like is less likely to occur. Between the second inclined wall portion 11ib and the first opposing region 11c, the angle of inclination may vary continuously or discontinuously. Between the second inclined wall portion 11ib and the second wall portion 11B, the angle of inclination may vary continuously or discontinuously.

As shown in fig. 6 and 7, the first structural body part 111 may also include a third inclined wall portion 11 ic. The third inclined wall portion 11ic is continuous with the first opposing region 11C and the third wall portion 11C. The third inclined wall portion 11ic is inclined with respect to the first direction D1 and inclined with respect to the second direction D2.

As shown in fig. 6, letters and lines such as "group" are drawn on the first wall portion 11A of the first structural body part 111. One side of the line is drawn as the ground plane to the floor.

By providing the third inclined wall portion 11ic, the corner portion becomes rounded, and damage or the like is less likely to occur. Between the third inclined wall portion 11ic and the first opposing region 11c, the angle of inclination may vary continuously or discontinuously. Between the third inclined wall portion 11ic and the third wall portion 11C, the angle of inclination may be continuously changed or may be discontinuously changed.

As shown in fig. 4(b) and 7, the first structural body part 111 may also include a fourth inclined wall portion 11 id. The fourth inclined wall portion 11id is continuous with the second inclined wall portion 11ib and the third inclined wall portion 11 ic. The fourth inclined wall portion 11id is inclined with respect to the first direction D1, and is inclined with respect to the second direction D2, and is inclined with respect to the third direction D3.

By providing the fourth inclined wall portion 11id, the corner portion becomes rounded, and damage or the like is less likely to occur. Between the fourth inclined wall portion 11id and the second inclined wall portion 11ib, the angle of inclination may vary continuously or discontinuously. Between the fourth inclined wall portion 11id and the third inclined wall portion 11ic, the angle of inclination may vary continuously or discontinuously.

For example, in the case where the second wall portion 11B described above is provided, the first structural body part 111 becomes an asymmetric shape.

As shown in fig. 1(a), 1(b) and 3, the first structural body part 111 may also include a fourth wall portion 11D. The fourth wall portion 11D is located between the first wall portion 11A and the first opposite wall portion 11Ac in the third direction D3. By providing the fourth wall portion 11D, for example, in the first wall portion 11A and the first opposing wall portion 11Ac, high strength is easily obtained. By providing the fourth wall portion 11D, for example, the strength against a load in the second direction D2 is improved.

As shown in fig. 3, the first structural body part 111 may also include a wall portion 11 Dx. The wall portion 11Dx is between the fourth wall portion 11D and the first intersection region 11X. The wall portion 11Dx connects the fourth wall portion 11D and the first intersection region 11X. By providing the wall portion 11Dx, for example, high strength is easily obtained.

As shown in fig. 3, a thickness t1 of the first side region 11S in the third direction D3 is substantially the same as a thickness tX1 of the first cross side region 11XS in the third direction D3. For example, the thickness t1 is 0.8 times or more and 1.2 times or less the thickness tX 1. By providing such a thickness, the amount of projection (position of the end) of the first structural part 111 with respect to the frame when the frame is inserted into the first pipe part 11P is the same as the amount of projection (position of the end) of the first structural part 111 with respect to the frame when the frame is inserted into the first cross pipe part 11 XP.

As shown in fig. 3, the first pipe portion 11P may include a first protrusion 11P. The first protrusion 11p is provided in the first side region 11S. The first protrusion 11p has a first protrusion height H1 in the direction from the first side region 11S to the first opposite side region 11 Sc. The first cross tube part 11XP includes first cross projections 11 XP. The first intersecting protrusion 11Xp is disposed in the first intersecting opposite side region 11 XSc. The first intersecting protrusion 11Xp has a first intersecting protrusion height HX1 in a direction from the first intersecting opposite side region 11XSc to the first intersecting side region 11 XS. In an embodiment, for example, first protrusion height H1 is substantially the same as first cross protrusion height HX 1. For example, the first protrusion height H1 is 0.8 times or more and 1.2 times or less the first cross protrusion height HX 1.

By providing the first projection 11P and the first cross projection 11Xp, when the frame is inserted into the first pipe part 11P or the first cross pipe part 11Xp, the first structural component 111 and the frame are combined with high accuracy. The variation in the relative position between the first structural body part 111 and the frame along the third direction D3 is suppressed.

As noted above, the first structural body part 111 may also include the second wall portion 11B. As shown in fig. 1(a), the position of the first opposing wall portion 11Ac in the third direction D3 is between the position of the first wall portion 11A in the third direction D3 and the position of the second wall portion 11B in the third direction D3.

As mentioned above, the first structural body part 111 may also include the third wall portion 11C. As shown in fig. 1(b), the position of the first intersecting opposite region 11Xc in the first direction D1 is between the position of the first intersecting region 11X in the first direction D1 and the position of the third wall portion 11C in the first direction D1.

As illustrated in fig. 1(a), a wall portion 11W may also be provided between the first opposing wall portion 11Ac and the second wall portion 11B. The wall portion 11W may also be omitted. By providing the wall portion 11W and the fourth wall portion 11D, the appearance is "beautiful". As illustrated in fig. 1(b), a wall portion may not be provided around the first intersection opening 11 Xo. This facilitates manufacture, for example.

Fig. 8 and 9 are schematic perspective views illustrating a bed device using the base of the first embodiment.

As shown in fig. 8, the bed arrangement 310 includes a frame 70 BF. The frame 70BF supports the lifting frame 70F. In this example, the lifting frame 70F is provided with a headboard 78H, a footboard 78F, a back board 70a, a knee board 70c, a foot board 70d, and the like.

As shown in fig. 9, the frame 70BF includes, for example, first to fourth end portions 77a to 77 d. An extension portion including a first end portion 77a and a fourth end portion 77d and an extension portion including a second end portion 77b and a third end portion 77c are provided. These extending portions are connected by a connecting member 77 f.

The direction from the first end 77a to the second end 77b and the direction from the fourth end 77d to the third end 77c correspond to, for example, the left-right direction of the bed device 310.

Any one of the first end portion 77a to the fourth end portion 77d of the frame 70BF is inserted into the first pipe portion 11P of the first structural body part 111. After the insertion, the first structural body 111 may be fixed to the end of the frame 70BF by any method. Various structures such as rivets, pins, or screws can be applied to fix the first structural body part 111 and the end of the frame 70 BF. For example, Snap-fit shapes (Snap-fit flaps) using "claws" provided on the first structural body part 111 may be applied to the fixing of the first structural body part 111 and the end of the frame 70 BF.

When the first structural body part 111 is provided at the first end portion 77a, the height of the frame 70BF is in one of the high state and the low state. When the first structural body part 111 is provided at the second end portion 77b, the height of the frame 70BF is the other of the high state and the low state. When the first structural body part 111 is provided at the third end portion 77c, the height of the frame 70BF is in one of the high state and the low state. When the first structural body part 111 is provided at the fourth end portion 77d, the height of the frame 70BF is the other of the high state and the low state.

For example, the first wall portion 11A to the third wall portion 11C and the first inclined wall portion 11ia to the fourth inclined wall portion 11id are provided in the direction of the outside of the bed device 310 with reference to the frame 70 BF. For example, the first end 77a or the third end 77c is inserted into the first pipe part 11P. At this time, the frame 70BF is in a high state. The second end 77b or the fourth end 77d is inserted into the first cross tube portion 11 XP. At this time, the frame 70BF is in a low state.

In the embodiment, in the case where the first structural body part 111 is symmetrical without providing the second wall portion 11B or the like, and in the case where the first structural body part 111 is provided at the first end portion 77a to the fourth end portion 77d, the frame 70BF may have any height of the high state and the low state.

As shown in fig. 1(a), the first structural body part 111 may also have a display 11 dp. In this example, the first wall portion 11A is provided with irregularities, which become the display 11 dp. For example, the insertion direction of the frame 70BF may be displayed by displaying 11 dp. A more convenient base may be provided.

As shown in fig. 1(a), the first structural body part 111 may also have a hole 11H. For example, the first structural body part 111 may be attached to the frame 70BF by inserting a fixing member (rivet or the like) into the hole 11H. In this example, the projection 11Hp is provided around the hole 11H. The projection 11Hp is provided around a part of the hole 11H. A part of the periphery of the projection 11Hp becomes a recess. This facilitates removal of, for example, rivets.

As described above, the first structural body part 111 includes the wall portion (second wall portion 11B). As described above, the first pipe portion 11P includes the first side region 11S and the first opposite side region 11 Sc. The third direction D3 from the first side region 11S to the first opposite side region 11Sc is along a third direction D3 intersecting a plane including the first direction D1 in which the first tube portion 11P extends and the second direction D2 in which the first intersecting tube portion 11XP extends. The first opposite-side region 11Sc is between the first side region 11S and the wall portion (second wall portion 11B) in the third direction D3. The second height of the frame BF when the frame 70BF of the furniture is inserted into the first pipe portion 11P is higher than the first height of the frame 70BF when the frame 70BF is inserted into the first cross pipe portion 11 XP.

When the first structural body part 111 has an asymmetric shape, it is preferable to provide a second structural body part having a shape different from that of the first structural body part 111.

(second embodiment)

In the second embodiment, the base 110 includes a second structural part. The second structural component has a shape that is inverted right and left with respect to the first structural component 111. For example, the second structural body part is mirror symmetric with respect to the first structural body part 111.

In one example, the second tube part 32P and the second cross tube part 32XP have, for example, a square tube shape. The second tube part 32P and the second cross tube part 32XP may be, for example, circular tube-shaped. The cross-sectional shape of the second pipe portion 32P (for example, the cross-sectional shape when cut along a plane perpendicular to the fourth direction D4) is arbitrary. The cross-sectional shape (for example, the cross-sectional shape when cut along a plane perpendicular to the fifth direction D5) of the second cross tube portion 32XP is arbitrary.

As shown in fig. 10(a) and 12, in this example, the second pipe portion 32P includes a second side region 32S and a second opposite side region 32 Sc. The direction from the second side region 32S to the second opposite side region 32Sc is along the sixth direction D6. The sixth direction D6 intersects a plane including the fourth direction D4 and the fifth direction D5. The sixth direction D6 is perpendicular to the fourth direction D4 and the fifth direction D5.

As shown in fig. 10(b) and 12, the second cross-hatched tube portion 32XP includes a second cross-side region 32XS and a second cross-opposite side region 32 XSc. The direction from the second cross side region 32XS to the second cross opposite side region 32XSc is along the sixth direction D6.

As shown in fig. 11(a) and 11(b), the second cross pipe portion 32XP extends in the fifth direction D5 and is connected to the second region 32 of the second pipe portion 32P. For example, the second cross section 32X of the second cross tube portion 32XP is connected to the second connection portion 32cp of the second section 32. As shown in fig. 11(b), in this example, the second region 32 includes a second hole 32 HL. The second tube part 32P and the second cross tube part 32XP are connected to each other through the second hole 32 HL.

As shown in fig. 10(a), the position of the second region 32 in the fifth direction D5 is between the position of the second intersection opening portion 32Xo in the fifth direction D5 and the position of the second opposing region 32c in the fifth direction D5. As shown in fig. 11(a) and 11(b), the position of the second intersection region 32X in the fourth direction D4 is between the position of the second opening 32o in the fourth direction D4 and the position of the second intersection opposing region 32Xc in the fourth direction D4. In one example, the second intersection area 32X is connected with the second connection portion 32cp of the second area 32.

As shown in fig. 11(a), 11(b), and 12, the distance along the fourth direction D4 between the second opening 32o and the second intersection region 32X is set to be a distance L3. The distance L3 corresponds to the distance between the second opening portion 32o and the second connecting portion 32cp along the fourth direction D4. A distance along the fifth direction D5 between the second intersection opening portion 32Xo and the second region 32 is set to a distance L4. Distance L3 is shorter than distance L4.

The frame 70BF of the bed can be inserted into the second pipe portion 32P. The frame 70BF can be inserted into the second cross pipe portion 32 XP.

In the second structural part 112, the distance L3 is shorter than the distance L4. Thus, the fourth height of the frame 70BF when the frame 70BF is inserted into the second pipe portion 32P is higher than the third height of the frame 70BF when the frame 70BF is inserted into the second cross pipe portion 32 XP. The height of the frame 70BF can be easily changed. According to the embodiment, a convenient base and a bed device can be provided.

As described above, the second structural part 112 includes the fifth wall portion 32E, the fifth opposing wall portion 32Ec, the second region 32, and the second intersecting region 32X. The second region 32 is provided between the fifth wall portion 32E and the fifth opposing wall portion 32 Ec. The second region 32 extends in a fourth direction D4. The second intersection region 32X is provided between the fifth wall portion 32E and the fifth opposing wall portion 32 Ec. The third intersection region 32X extends in a fifth direction D5. The sixth direction D6 from the fifth wall portion 32E to the fifth opposing wall portion 32Ec intersects the plane including the fourth direction D4 and the fifth direction D5. The height of the frame 70BF when the frame 70BF is placed in the second region 32 between the fifth wall portion 32E and the fifth opposite wall portion 32Ec is different from the height of the frame 70BF when the frame 70BF is placed in the second intersection region 32X between the fifth wall portion 32E and the fifth opposite wall portion 32 Ec. For example, the height of the frame 70BF when the frame 70BF is placed in the second region 32 is substantially the same as the height of the frame 70BF when placed in the first region 11 between the first wall portion 11A and the first opposing wall portion 11A. The height of the frame 70BF when the frame 70BF is placed at the second intersection region 32X is the same as the height of the frame 70BF when placed at the first intersection region 11X between the first wall portion 11A and the first opposing wall portion 11 Ac.

Second structural part 112 may also include second opposing region 32c and second intersecting opposing region 32 Xc. The direction from the second region 32 to the second opposing region 32c is along a fifth direction D5. The direction from the second intersection region 32X to the second intersection opposing region 32Xc is along the fourth direction D4. When the frame 70BF is placed on the second region 32, the frame 70BF is between the second region 32 and the second opposing region 32 c. When the frame 70BF is placed at the second intersection region 32X, the frame 70BF is between the second intersection region 32X and the second intersection opposing region 32 Xc.

As shown in fig. 10(a), the distance along the fifth direction D5 between the second region 32 and the second opposing region 32c is set to a distance Ls 4. As shown in fig. 10(b), the distance along the fourth direction D4 between the second intersection region 32X and the second intersection opposing region 32Xc is set to a distance Ls 3. In an embodiment, distance Ls4 is substantially the same as distance Ls 3. In one state, the frame is inserted between the second region 32 and the second opposing region 32 c. In the other state, the frame is inserted between the second intersection region 32X and the second intersection opposing region 32 Xc. In these states, the frame is stably inserted, and positional deviation can be suppressed.

As shown in fig. 11(a) and 11(b), the second region 32 is continuous with the second intersection opposing region 32 Xc. The second region 32 comprises at least one second hole 32 HL. The inner space of the second pipe part 32P is connected to the inner space of the second cross pipe part 32XP via a second hole 32 HL. For example, when the second structural member 112 is cleaned, it is easily dried. It is easy to provide a clean base 110.

As shown in fig. 10(a), 10(b) and 12, the second structural part 112 may include a fifth wall portion 32E and a fifth opposite wall portion 32 Ec.

The eighth inclined wall portion 32ih is inclined with respect to the fourth direction D4, and inclined with respect to the fifth direction D5, and inclined with respect to the sixth direction D6.

By providing the eighth inclined wall portion 32ih, the corner portions are rounded, and damage or the like is less likely to occur.

Between the eighth inclined wall portion 32ih and the seventh inclined wall portion 32ig, the angle of inclination may be continuously changed or may be discontinuously changed.

For example, in the case where the sixth wall portion 32F is provided, the second structural part 112 has an asymmetric shape.

As shown in fig. 12, the thickness t2 of the second opposing side region 32Sc in the sixth direction D6 is substantially the same as the thickness tX2 of the second crossing opposing side region 32XSc in the sixth direction D6. For example, the thickness t2 is 0.8 times or more and 1.2 times or less the thickness tX 2. By providing such a thickness, the amount of projection (position of the end) of the second structural part 112 with respect to the frame 70BF when the frame 70BF is inserted into the second pipe portion 32P is the same as the amount of projection (position of the end) of the second structural part 112 with respect to the frame 70BF when the frame 70BF is inserted into the second cross pipe portion 32 XP.
