BED DEVICE

To provide a bed device which has a caster mechanism excellent in the operability and functionality.SOLUTION: A caster mechanism comprises: a caster; a brake member which has a brake pad; a holder which holds the brake member in a movable manner in the vertical direction and holds the caster in a rotatable manner; a lock lever which has a first step-in part and is rotatable around the first axis; and a release lever which has a second step-in part and is rotatable around the second axis in parallel to the first axis. The caster mechanism can be switched between the lock release state in which the caster contacts the installation surface and the brake pad is apart from the installation surface and the lock state in which the caster is apart from the installation surface and the brake pad contacts the installation surface. In a case where the caster mechanism is in the lock release state, the caster mechanism is switched to the lock state when the first step-in part is stepped. In a case where the caster mechanism is in the lock state, the caster mechanism is switched to the lock release state when the second step-in part is stepped.SELECTED DRAWING: Figure 10 【課題】操作性や機能性に優れたキャスタ機構を備えるベッド装置を提供する。【解決手段】キャスタ機構は、キャスタと、ブレーキパッドを有するブレーキ部材と、ブレーキ部材を鉛直方向に移動可能に保持しキャスタを回動可能に保持するホルダと、第１踏み込み部を有し第１軸を中心に回動可能なロックレバーと、第２踏み込み部を有し第１軸と平行な第２軸を中心に回動可能な解除レバーとを備える。キャスタ機構は、設置面にキャスタが接触しブレーキパッドが設置面と離間したロック解除状態と、キャスタが設置面と離間しブレーキパッドが設置面と接触したロック状態との間で切り替え可能である。キャスタ機構がロック解除状態にあるとき、第１踏み込み部が踏まれるとキャスタ機構がロック状態に切り替わる。キャスタ機構がロック状態にあるとき、第２踏み込み部が踏まれるとキャスタ機構がロック解除状態に切り替わる。【選択図】図１０
