Abstract:
1. A spray coating device for forming sprayed coatings on inner surfaces of at least two cylinder bores included in an engine having a cylinder block, the at least two cylinder bores orientated in different directions with respect to an axis for a crankshaft, the device comprising: a spray gun operable to enter respective ones of the at least two cylinder bores; a rotator supporting the cylinder block in a rotatable fashion around the axis for the crankshaft; and a driving device operable to rotate the rotator and the cylinder block supported by the rotator about the axis for the crankshaft and between a first spraying position and a second spraying position, the first spraying position corresponding to a first one of the different directions and the second spraying position corresponding to a second one of the different directions, wherein the rotator has a convex rounded surface facing a rotator-holding base and the rotator-holding base has a concave rounded surface corresponding to the convex rounded surface of the rotator; and wherein a clearance gap is defined between the convex and concave rounded surfaces.
