The transverse bar is inserted into the insertion unit of the connection member to be movable, and a first motor drives a motor while being installed inside a case. A pinion(p) is inserted into inside insertion unit of the connection member to be rotatable, a second motor is installed inside the insertion unit of the connecting member and drives the pinion. |
