In the device, the rack has a lock tooth that is operated to engage and disengage from the rack, and the tooth surface of the lock tooth of the pedestal lock body attached to the hull is such that the rack and the lock tooth are engaged with each other when the rack and the lock tooth engage with each other. A wedge-shaped shim that is urged to move in the wedge-in direction through the misalignment gap is slidably mounted, and the upper and lower end surfaces of the pedestal lock body and the respective end faces are connected to supporting surfaces provided on the hull opposite to each other. A wedge member is inserted between each end face and the support surface, and the wedge member is inserted into and removed from the wedge independently. A lifting pedestal wedge locking device for an offshore work platform in which a means is arranged on the side of the locking body. (2) The lifting pedestal wedge locking device for an offshore working platform as set forth in claim 1, wherein the wedge-shaped shims are slidably attached to both tooth surfaces of the lock teeth and the wedge-input directions are opposite to each other.
