とを目的とする。According to such a stepping type, when the actuating rod is actuated to lock the wheels, the stepping type pedal is depressed, but when the lock is released, the stepping type is depressed. The pedal must be operated in the reverse direction or a separate unlocking pedal must be provided for the operation. In this case, since the treadle pedal can be strongly depressed when locking the wheels, a large force is required for the operation of lifting the treadle pedal in the opposite direction, and the operation is also difficult. When the pedal for unlocking is provided, normally, the pedal for unlocking should be provided on the side opposite to the position where the treadle pedal for locking operation is provided, that is, on the inner side below the bed. Therefore, you must move each time you unlock. The present invention has been made in view of the above problems, and an object of the present invention is to provide a caster interlocking lock operation mechanism capable of locking and unlocking wheels by simply depressing.
