<4. Features>
According to the care chair according to this embodiment, the following effects can be obtained.

(1) The chair 12 is provided in front of the support body 11 formed in an L shape when viewed from the side, and the chair 12 is configured to tilt. Do not move backwards. Therefore, the head of the cared person sitting on the chair 12 does not fall backward from the support 11 . Therefore, the cared person's anxiety can be suppressed.

(2) Since the chair 12 does not move to the rear of the support 11 , there is no need for an operation area behind the support 11 for tilting the chair 12 . Therefore, the body portion 2 can be brought close to the fourth wall portion 84 of the bathtub 8, and the bathtub 8 can be widely used. Moreover, behind the support body 11, a caregiver's movement space can be secured.

(3) Since the chair 12 tilts by moving the backrest 122 downward while the seat 121 faces forward, the force required for tilting can be reduced. Also, when the chair 12 is tilted, formation of a large dead space between the support 11 and the chair 12 can be suppressed. Therefore, the bathtub 8 can be widely used. In addition, it is possible to prevent the cared person's sitting position from becoming higher due to the inclination of the chair 12, so that the cared person's anxiety can be suppressed.

(4) The chair 12 tilts in a well-balanced manner by moving the seat portion 121 forward while the backrest portion 122 moves downward. That is, unlike the conventional example, the entire chair does not incline so as to be lifted up, so overturning can be prevented. Furthermore, since the force acting on the support body 11 and the body part 2 that receive the chair 12 is dispersed, it is possible to suppress the biased force acting on the support body 11 and the like. As a result, damage to the care chair 100 can be prevented.

(5) The first portion 111 of the support 11 extends generally horizontally, but can be slightly inclined. For example, if the chair 12 is tilted downward as it goes forward, the care-receiver's own weight can help him when tilting the chair 12, that is, when moving the seat portion 121 forward. , the burden on the caregiver who operates the operating handle 139 can be reduced. On the other hand, when the seat portion 121 is moved backward, a large force is not required because the force acts to return the seat portion 121 by its own weight.

(6) Since the operating handle 139 is provided in front of the seat portion 121, the tilting operation of the chair 12 can be performed from the seated care recipient side. Therefore, when the operating handle 139 is operated, the caregiver can work in a position where the caregiver's eyes meet with the caregiver's eyes, so that the caregiver's anxiety can be suppressed.
