[ 0021 ]
The bathtub main body 50 to which the bathtub headrest 1 is attached can store hot water W to such an extent that the headrest main body 10 is not immersed even if the bather takes a bath. When a bather takes a bath, he lies along the inclined surface 51 and then places the head H in accordance with the curved shape of the head contact portion 11 of the headrest body 10 (FIG. 6). Thereby, the bather is in a relaxed bathing posture because the head H is supported by the headrest body 10 and the chin is pulled. At this time, since the headrest body 10 has an elastic force, the weight of the head H is absorbed by the elastic force, and the bather does not need to apply an excessive force to the head H. In addition, since the surface 12 of the headrest body 10 is subjected to uneven slip prevention processing, the head H can be prevented from sliding down in accordance with the inclined surface 51. Further, since the headrest body 10 has a cylindrical shape, a soft contact state with the head H is formed, and on the other hand, the headrest body 10 is held by being inserted and held in the curved support piece 25. It is possible to prevent the headrest body 10 from rotating in accordance with the movement in the direction.

[ 0023 ]
According to the present embodiment, by attaching the bathtub headrest 1 to the upper part of the inclined surface 51 in the bathtub body 50, the bather can lie on the body and place the head H on the headrest body 10. Therefore, while the whole body can be brought close to being stretched, a state in which the chin of the head H is pulled can be formed, and an easy bathing posture can be maintained during bathing.
[ 0024 ]
Further, tubs headrest 1, since the headrest body 10 can be easily attached and detached from the support member 20 can be easily cleaned or replaced abutting headrest body 10 of the head H.
[ 0025 ]
Moreover, since the headrest main body 10 has an elastic force, the weight of the head H can be absorbed and the necessity of applying an excessive force to the bather can be eliminated. Further, the surface 12 of the headrest body 10 is subjected to a non-slip treatment for preventing the head H from sliding down, and the headrest body 10 is inserted into and held by a curved support piece 25 to support the headrest. Since the vertical rotation of the headrest body 10 with respect to 25 is prevented, the bathing posture can be maintained even when bathing for a long time.
[ 0026 ]
As shown in FIGS. 10 and 11, the support member 20 is fixed to the top plate surface 50 a following the inclined surface 51 of the bathtub main body 50, and the headrest main body 10 is inclined by the inclined surface 51. Can be installed along. Thereby, even if it is a case where a bather's head H protrudes upwards from the top-plate surface 50a, the bather can form the support state of the head H simultaneously with a body supine. In particular, as shown in the figure, the head changes according to the posture and body shape of the bather by changing the height of the headrest body 10 from the top surface 50a, the fixing position of the support member 20 to the top surface 50a, and the like. A support state corresponding to the position of H can be formed.
[ 0027 ]
Further, as shown in FIG. 12, the headrest body 10 is formed into a tube shape with a synthetic resin material such as a rubber material, and the same as in the above embodiment by injecting a gas such as air or a liquid such as water. It can form in the shape of a bag which expands to the shape. Thereby, since it has elasticity and the surface is formed with the rubber material, the anti-slip effect can be obtained without any treatment.
