in a case where a width of the first armrest is d1, a width of the second armrest is d2, and a width of the first support portion is D, a length L from a L-shaped bending portion of the L shape member to the third drive unit is L={D+(d1−d2)}/2 or less.
20 . The wheelchair according to claim 18 , wherein
in a case where a width of the first armrest is d1, a width of the second armrest is d2, and a width of the first support portion is D, a length L from a L-shaped bending portion of the L shape member to the third drive unit is L={D+(d1−d2)}/2 or less.
21 . The wheelchair according to claim 15 , wherein
the first rotation axis is arranged at a position offset from a center in a width direction of the first seat portion.
22 . The wheelchair according to claim 16 , wherein
the first rotation axis is arranged at a position offset from a center in a width direction of the first seat portion.
23 . The wheelchair according to claim 17 , wherein
the first rotation axis is arranged at a position offset from a center in a width direction of the first seat portion.
24 . The wheelchair according to claim 19 , wherein
the first rotation axis is arranged at a position offset from a center in a width direction of the first seat portion.
25 . The wheelchair according to claim 19 , wherein
the first rotation axis is arranged at a position offset from a center in a width direction of the first seat portion.
26 . The wheelchair according to claim 15 , wherein
when being rotated about the first rotation axis, the second armrest is moved in a direction of going away from a side part of the first support portion and then moved in a direction of coming close to a back surface of the first back bottom support portion.
27 . The wheelchair according to claim 16 , wherein
when being rotated about the first rotation axis, the second armrest is moved in a direction of going away from a side part of the first support portion and then moved in a direction of coming close to a back surface of the first back bottom support portion.
28 . The wheelchair according to claim 17 , wherein
when being rotated about the first rotation axis, the second armrest is moved in a direction of going away from a side part of the first support portion and then moved in a direction of coming close to a back surface of the first back bottom support portion.
29 . A bed comprising:
the wheelchair according to claim 15 ; and
a bed base portion to be combined with the wheelchair to form the bed.
30 . A bed comprising:
the wheelchair according to claim 16 ; and
a bed base portion to be combined with the wheelchair to form the bed.
31 . The bed according to claim 29 , wherein
the second armrest is an armrest on a side of the bed base portion of the first support portion.
32 . The bed according to claim 31 , wherein
the retreated position is placed on an opposite side of the bed base portion on a back surface side of the first support portion.
33 . The bed according to claim 29 , further comprising:
a combination detecting unit that detects combination between the wheelchair and the bed base portion; and
a second control unit that moves the second armrest of the wheelchair in which a posture of the first seat portion is in a tilt posture from the deployed position to the retreated position when the combination detecting unit detects the combination.
34 . The bed according to claim 29 , further comprising:
a first operating unit that instructs the first control unit that controls an action of the bed on an operation; and
a second operating unit that instructs the second control unit that controls an action of the wheelchair and a third control unit that controls the third drive unit on an operation.
