To provide a chair having high degree of freedom in design for easily attaching a second part to a first part.SOLUTION: A chair includes a lumber base RB and a lumber pad RP. The lumber pad RP has an operation body r4 that can pass through a through hole r211 of the lumber base RB only when taking a preparation attitude (J), a pad body r3 that cannot pass through the through hole r211, and a connection shaft part r5. The lumber pad RP is installed to the lumber base RB by rotating the lumber pad RP around the axis of the connection shaft part r5 to change its attitude from the preparation attitude (J) to an installation attitude after passing the operation body r4 into the through hole r211.SELECTED DRAWING: Figure 25

    【課題】第一部品に対して第二部品を容易に取り付ける設計の自由度に優れた椅子を提供する。【解決手段】ランバーベースRBとランバーパッドRPとを備えた椅子であって、ランバーパッドRPが、準備姿勢(J)を採る場合にのみランバーベースRBの貫通孔r211を通過し得る操作体r4と、貫通孔r211を通過不能なパッド本体r3と、連結軸部r5とを備え、貫通孔r211に操作体r4を通過させた後に、ランバーパッドRPを連結軸部r5の軸心回りに回転させて準備姿勢(J)から装着姿勢に姿勢変更することにより、ランバーパッドRPがランバーベースRBに対して装着されている。【選択図】図25
