An air cylinder apparatus equipped with a fall prevention mechanism, wherein the air cylinder apparatus includes a cylinder body and a piston rod which advances and retreats by supplying and discharging pressurized air to and from the cylinder body, and wherein the fall prevention mechanism includes a fixed member which is immovable with respect to the cylinder body; a plurality of brake members which are supported by the fixed member to be capable of coming into and out of contact with the fixed member; a biasing member which presses the plurality of brake members against the piston rod to lock the piston rod to the fixed member; and a lock-release air mechanism which holds, against a biasing force of the biasing member, the brake members in a non-contact position with the piston rod, the lock-release air mechanism operating by a pressurized air source that is common with that of the air cylinder apparatus. |
