PROBLEM TO BE SOLVED: To operate a footrest without separately providing operation means.SOLUTION: In an ottoman device having a footrest, a link mechanism 20R and lock means 30, the link mechanism 20R is constituted of at least four links and a joint shaft, and the lock means 30 is constituted of an internal tooth member 31 fixed to the link 21a, an external tooth member 32 installed on the link 21b in a rockable state around a position dislocated from the joint shaft 22a and an external tooth energization member 33. The internal tooth member 31 and the external tooth member 32 are provided with retreat cam mechanisms 31d and 32d for retreating the external tooth member 32 to a retreat position when the footrest tries to rotate upward by going over an upper limit of a use angle and return cam mechanisms 31e and 32e for returning the external tooth member 32 to a meshing position when the footrest of rotating downward in a state where the external tooth member 32 exists in the retreat position, reaches the vicinity of a storage position.SELECTED DRAWING: Figure 5

    【課題】操作手段を別途設けることなくフットレストを操作できるようにする。【解決手段】フットレストとリンク機構20Rとロック手段30とを備えたオットマン装置において、リンク機構20Rを、少なくとも4本のリンクとジョイント軸とで構成し、ロック手段30を、リンク21aに固定される内歯部材31と、ジョイント軸22aからずれた位置を中心として揺動可能な状態でリンク21bに取り付けられる外歯部材32と、外歯付勢部材33とで構成した。内歯部材31と外歯部材32には、フットレストが使用角度の上限を越えて上向きに回動しようとした際に外歯部材32を退避位置に退避させる退避カム機構31d,32dと、外歯部材32が退避位置にある状態で下向きに回動するフットレストが格納位置付近に達した際に外歯部材32を噛合位置へ復帰させる復帰カム機構31e,32eとを設けた。【選択図】図5
