座部7は、四節リンク19と伸縮体20とでなる座部支持部6で支持され、収納式歩行車1の中央の歩行エリア42に進出した使用位置と、収納式歩行車1の前部へ寄せた収納位置とに、移動可能に構成される。
The seat 7 is composed of a seat frame 18 attached to the front portion of the seat support 6 and a seat surface 33 attached to the upper portion of the seat frame 18, and a patient sits there. The planar view shape of the seat portion 7 is similar to the front view shape of the substantially Erlenmeyer flask.
The seat portion 7 is supported by a seat portion support portion 6 including a four-bar link 19 and a telescopic body 20, and the use position that has advanced into the central walking area 42 of the retractable walking vehicle 1 and the front of the retractable walking vehicle 1. It is configured to be movable to the storage position close to the part.

又、上・下平行アーム22・23はその各基部を中心に垂直方向に回動でき、その回動により上・下平行アーム22・23の各先部に取り付けられる座部7は昇降する。
伸縮体20は、操作者により、座部7を下降させるほどに縮小し、座部7を上昇させるほどに伸長するものである。
解除具21は、常時は伸縮しない伸縮体20の固定作用を、座部7の高さを変更する時に解除するものである。
座部7は、使用位置から収納位置へ移動できると共に、使用位置において高さ調節できるものである。
Further, the upper and lower parallel arms 22 and 23 can be rotated in the vertical direction around their respective bases, and the seats 7 attached to the respective front portions of the upper and lower parallel arms 22 and 23 are moved up and down by the rotation.
The stretchable body 20 is contracted by the operator as the seat portion 7 is lowered, and is expanded as the seat portion 7 is raised.
The release tool 21 releases the fixing action of the stretchable body 20 that does not normally expand and contract when the height of the seat portion 7 is changed.
The seat portion 7 can be moved from the use position to the storage position and can be adjusted in height at the use position.

肘受8は、患者が肘を乗せるものであり、肘支柱4の頂部に肘受8が、前方に僅か下降する前傾に(=前傾姿勢)、且つ、内側方にも僅か下降傾斜状に(=内傾姿勢)取着される。
肘受8の前部左右に、患者が握る握り部36が斜状に設けられる。
The elbow support 8 is for a patient to put an elbow on. The elbow support 8 is on the top of the elbow post 4 so that the elbow support 8 tilts forward slightly (= forward tilting posture) and slightly inclines downward toward the inside. (= Inclined posture).
On the left and right sides of the front part of the elbow support 8, grips 36 that are gripped by the patient are provided in an oblique manner.

肘受8の後部に、患者の背部位置に有って適宜患者の背部に接触し背部を支える背部サポート37が設けられる。
尚、図4中、39はスペーサー、40はストッパー用軸、41は捻りばねである。
