- the state in which the engaging member 27 is engaged with the engaging portion 24 is released. Since the engaging member 27 is urged backward by a spring or the like, the engaging member 27 engages with one of the engaging portions 24 when the operator stops sliding the tilt operation portion 28 .
- the main body 10 can change the angle of the seat unit 11 with respect to the ground surface by means of the angle changing mechanism 25 having such a configuration. That is, when the engaging member 27 is engaged with the engaging portion 24 , the seat unit 11 is positioned with respect to the ground contact member 21 . When the engagement member 27 is disengaged from the engagement portion 24 , the seat surface unit 11 is rotatable about the rotation shaft 29 with respect to the ground contact member 21 . In this case, as the seat surface unit 11 rotates with respect to the grounding member 21 , both end portions of the engaging member 27 move within the long hole portions 24 b connected to the engaging portion 24 . That is, the grounding member 21 is configured to be displaceable between at least the first position and the second position with respect to the seat unit 11 . In addition to the engagement member 27 and the tilting operation portion 28, it may be interpreted that the grounding member 21 is included in the angle changing mechanism 25. FIG.

- the chair 1 is tilted by tilting the seat unit 11 backward up to about 30 degrees from the non-tilted state shown in FIG. state is possible.
- the inclination angle (tilt angle) of the seat unit 11 is determined by the position of the engaging portion 24 with which the engaging member 27 engages.
- the seat unit 11 can be set to six tilt angles from the minimum tilt angle (0 degrees) to the maximum tilt angle (about 30 degrees). Thereby, a preferable tilt angle can be set according to the user's condition, application, and the like. Since the seat unit 11 rotates with respect to the grounding member 21, the backrest 50 supported by the seat unit 11 also rotates.
- the chair 1 can be tilted as a whole so that the posture of the user is maintained.
- the positions and number of the engaging portions 24 with which the engaging member 27 can engage are not limited to this. That is, the settable tilt angle may be changed by changing the number of the engaging portions 24 or the like.
- the angle changing mechanism 27 may have, for example, an engaging member that can be displaced so as to reciprocate in the Y direction in accordance with the user's operation. Such a mechanism can be realized, for example, by appropriately using a link mechanism or the like.

- the chair 1 can be easily put into use when necessary by configuring so that the magnetic attraction force acting between the first attraction part 11b and the second attraction part 50b can be released with a light force. can do. Also, the user pulls out the protruding member 31 from the main body 10 and protrudes it later. This results in the state shown in step S12.
- step S12 the support member 60 is positioned relatively downward, and the support member 60 and the pad 67 of the headrest 65 overlap in the front-rear direction. Therefore, the positions of the support member 60 and the headrest 65 are adjusted to suit the user. As a result, the chair 1 is put into the use state shown as step S13, and the user can sit on it.
- the chair 1 can be tilted backward from the state of use shown in step S13. That is, the user may operate the tilt operation unit 28 to set the tilt angle shown in step S14, for example.
- the tilt operation portion 28 By operating the tilt operation portion 28 in a predetermined manner, for example, by displacing it forward, the engagement of the engaging member 27 with the engaging portion 24 is temporarily released, and the seat surface unit is moved to the ground contact member 21 . 11 is made rotatable. In this state, the seat unit 11 is rotated backward together with the backrest 50 . Then, by canceling the operation of the tilt operation portion 28 and engaging the engagement member 27 with another engagement portion 24 corresponding to the current tilt angle, the tilt angle can be set and fixed. .

- the backrest 50 is made rotatable with respect to the main body 10 by operating the opening/closing operation portion 46 in a predetermined manner, for example, by sliding it to the right. In this state, the backrest 50 is displaced from the open state to the closed state. As a result, the backrest 50 can be reliably maintained in the open state when such an intentional user operation is not performed.
- the chair 1 can be compact in the stored state. Therefore, the user can easily carry the chair 1. Since the chair 1 has a main body 10 that can be placed on the placement surface, it can be easily used anywhere as long as there is enough space to place the main body 10 thereon. It is very easy to change the chair 1 from the stowed state to the used state and from the used state to the stowed state. Therefore, it is possible to provide a highly convenient chair 1 that can be easily carried and used in various places.
- the chair 1 according to the present embodiment can also be used as a chair having a so-called sitting position holding function for users who have difficulty in maintaining a sitting position by themselves due to a functional disorder in a part of the body. can be used.
