By providing the second members 21b and 22b with minute irregularities, the friction with the flange step portion 114 of the bathtub 110 that comes into contact with the second members 21b and 22b increases. When the bath lid 100 is placed on the flange step portion 114 on the upper part of the bathtub 110 with the cushion material 14 facing up, the second members 21b and 22b come into contact with the flange step portion 114, and the minute parts provided on the second members 21b and 22b are provided. Due to the unevenness, friction is large and it is hard to slip. On the other hand, when the bath lid 100 is placed on the flange step portion 114 on the upper part of the bathtub 110 with the surface material 13 facing up, the first members 21a and 22a come into contact with the flange step portion 114, and the surfaces of the first members 21a and 22a. Because it is flat, friction is small and it is easy to slip.

Further, the surfaces of the second member 21b of the covering portion 21 and the second member 22b of the covering portion 22 are provided with minute irregularities to flatten the surfaces of the first members 21a and 22a, and the hardness of the second members 21b and 22b is increased. It may be the same as the hardness of the first members 21a and 22a. In this case, the hardness of the first members 21a and 22a and the second members 21b and 22b has a shore A hardness of 90 or more according to JIS K6253. Even if the hardness of the second members 21b and 22b is the same as the hardness of the first members 21a and 22a, the bath lid 100 is placed on the flange step portion 114 on the upper part of the bathtub 110 with the cushion material 14 facing up. The friction with the flange step portion 114 of the bathtub 110, which is in contact with the two members 21b and 22b due to the minute irregularities, is large and is difficult to slip. On the other hand, when the bath lid 100 is placed on the flange step portion 114 on the upper part of the bathtub 110 with the surface material 13 facing up, the first members 21a and 22a come into contact with the flange step portion 114, and the surfaces of the first members 21a and 22a. Because it is flat, friction is small and it is easy to slip.

The features of the above modified examples will be described.
In the bath lid 100 according to the modified example, the surfaces of the first portions 21a and 22a of the covering portions 21 and 22 of the covering material 2 are flat, and the surfaces of the second portions 21b and 22b are provided with irregularities. As a result, the bath lid 100 is slippery in a state where the first members 21a and 22a are in contact with the flange step portion 114 on the upper part of the bathtub 110, and the second members 21b and 22b are brought into contact with the flange step portion 114 on the upper part of the bathtub 110. Since the bath lid 100 becomes less slippery in the state, the convenience of the bath lid 100 is improved.

Further, the bath lid 100 includes a plate-shaped lid main body 1 and a covering material 2 that covers both side edges of the lid main body 1. In the covering portions 21 and 22 of the covering material 2, the surfaces of the first portions 21a and 22a covering the one-sided edge of the lid body 1 in each covering portion are flat, and the second covering the other-sided edge. The surfaces of the portions 21b and 22b are provided with irregularities. As a result, even when the hardness of the second members 21b and 22b is the same as the hardness of the first members 21a and 22a, the bath lid 100 is in a state where the first members 21a and 22a are in contact with the flange step portion 114 on the upper part of the bathtub 110. It is easy to slip, and the bath lid 100 is less likely to slip when the second members 21b and 22b are in contact with the flange step portion 114 on the upper part of the bathtub 110, so that the convenience of the bath lid 100 is improved. As long as the covering material 2 has the first portions 21a and 22a and the second portions 21b and 22b, the covering material 2 may have a configuration in which there is no portion covering the outer peripheral end surface of the lid main body 1, as described above. The covering material 2 may have the end face covering portions 21c and 22c.

In the above-described embodiment and modification, an example is shown in which the bath lid 100 according to the present invention is used by being placed on the flange step portion 114 of the bathtub 110, but the flange on the upper part of the bathtub 110 in which the flange step portion 114 is not provided is shown. It can also be used by mounting it on the unit 112.

The above description has been made based on the embodiment of the present invention. It will be appreciated by those skilled in the art that these embodiments are exemplary and that various modifications and modifications are possible within the claims of the invention, and that such modifications and modifications are also within the claims of the present invention. It is about to be done. Therefore, the descriptions and drawings herein should be treated as exemplary rather than limiting.
