To provide an armrest structure which can perform positioning easily with one hand.SOLUTION: An armrest structure includes: an armrest part 30 which is attached to a fixed frame 25 so as to be swingable in a horizontal direction. The armrest part 30 includes: a button member 40 which is disposed at a tip of the armrest part 30 so as to enable pressing operation; and a biasing member 48 which biases the button member 40. The fixed frame 25 and the button member 40 fix swinging of the armrest part 30 by a pin 27, provided at one of the fixed frame 25 and the bottom member 40, engaging with an engagement groove 43a provided at the other. The biasing member 48 biases the button member 40 in a direction where the pin 27 and the engagement groove 43a are engaged with each other. When the button member 40 is pushed in against the biasing force of the biasing member 48, the pin 27 is disengaged from the engagement groove 43a to enable the armrest part 30 to swing.SELECTED DRAWING: Figure 7
【課題】片手で容易に位置調整が行えるアームレスト構造を提供する。【解決手段】固定フレーム25に対して水平方向に揺動可能に取り付けられた肘掛部30を備え、前記肘掛部30は、前記肘掛部30の先端に押動操作可能に配置されたボタン部材40と、前記ボタン部材40を付勢する付勢部材48と、を備える。前記固定フレーム25と前記ボタン部材40とは、一方に設けられたピン27と他方に設けられた係合溝43aとが係合することで、前記肘掛部30の揺動を固定し、前記付勢部材48は、前記ピン27と前記係合溝43aとが係合する方向に前記ボタン部材40を付勢しており、前記ボタン部材40が前記付勢部材48の付勢力に抗して押し込まれたときに、前記ピン27が前記係合溝43aから外れて、前記肘掛部30が揺動可能となる。【選択図】図7
