LAUNCHING CYLINDER SUPPORT DEVICE

PROBLEM TO BE SOLVED: To provide a launching cylinder support device to bring a device into an on-vehicle state by adding a slight a mount of parts as on-vehicle, perform vertical regulation of a launching cylinder throughout a wide range, and further suppress the height of a whole to a low value. SOLUTION: A launching cylinder support metal 2 revolvable to an outer periphery and provided with a bearing box outside 5 and a revolving operation mechanism 7 is fixed on a car body. Further, quadric parallel links 14 and 15 are coupled to both the right and left sides of the outside of a bearing box by means of pins. A drive mechanism is provided to vertically and longitudinally move a base 20 through parallel movement of the quadric parallel link. The intermediate of a launching cylinder 36 is supported on a base through a support rod 37 and the lower end part of the launching cylinder is pivotally mounted on the central axis of a support fitment. A displacement absorbing mechanism to absorb the horizontal component of displacement of a support rod 37 through the quadric parallel links 14 and 15 during regulation of the vertical angle of the launching cylinder is arranged between the base 20 and the support rod 37.
