PROBLEM TO BE SOLVED: To provide a caster lock operation mechanism which can reduce a load on a user even if the mechanism has many casters.SOLUTION: A caster lock operation mechanism comprises: a pedal base 6 fitted to a cradle 3; a lock pedal 7 which is so provided on the pedal base 6 as to be rotatable around a horizontally extending first axis, of which a first end side is provided with a lock cover 71, and which is connected to a horizontal shaft 22 of a caster 2; and a release pedal 8 which is so provided on the pedal base 6 as to be rotatable around a second axis parallel to the first axis, of which a first end side is connected to the first end side of the lock pedal 7, and of which a second end side is provided with a release bar 81. When pressing down the lock lever 71, the horizontal shaft 22 is rotated in a first direction, thereby locking the caster 2, and the release pedal 8 is rotated in a normal direction, thereby positioning the release bar 81 at an upper position, and when pressing down the release bar 81 in this state, the lock pedal 7 is rotated in a reverse direction, and the horizontal shaft 22 is rotated in a second direction, thereby releasing lock of the caster 2.SELECTED DRAWING: Figure 9

    【課題】 多くのキャスタを有する場合でも、ユーザへの負担を軽減することが可能なキャスタロック操作機構を提供する。【解決手段】 架台3に取りけられたペダルベース6と、水平に延びる第1の軸心を中心に回動自在にペダルベース6に配設され、第1の端部側にロックバー71が設けられ、キャスタ2の水平軸22に連結されたロックペダル7と、第1の軸心に平行な第2の軸心を中心に回動自在にペダルベース6に配設され、第1の端部側がロックペダル7の第1の端部側に連結され、第2の端部側に解除バー81が設けられた解除ペダル8と、を備える。ロックバー71を押し下げると、水平軸22が第1の方向に回動してキャスタ2がロックされるとともに、解除ペダル8が正方向に回動して解除バー81が上位に位置し、この状態で解除バー81を押し下げると、ロックペダル7が逆方向に回動し、水平軸22が第2の方向に回動してキャスタ2がロック解除される。【選択図】 図9
