The tension rod is formed such that the advancing/retracting rod is supported so as to project freely onto the longitudinal extension of the distal end of the guide body, and a rack is provided along the upper edge of the advancing/retracting rod. A lock arm having a locking pawl that engages with the teeth of the rack is pivotally mounted to enable seesaw movement, and a hook that retains the locking claw in a state where it is removed from the rack by latching the rear end portion of the lock arm. A safety mechanism for an elevating device comprising: a pressing body which presses the tip of the lock arm toward the rack side to release the lock from the hook when the table is lowered;
