Abstract: A foot stretching/checkup device includes: a motor unit; a footrest unit including a lower footrest configured to be rotated about a first rotation axis, an upper footrest configured to be rotated about a second rotation axis and a connecting member connecting the upper footrest and the lower footrest; and a coupling unit including an arm portion rotated by the motor unit and a rotary coupler coupled to the upper footrest. The upper footrest is configured to be rotated by a predetermined angle about the second rotation axis by the rotation of the arm portion. The lower footrest is configured not to be rotated about the first rotation axis by rotation of the arm portion until the upper footrest is rotated by the predetermined angle.
