Abstract
A film forming apparatus () includes a mask body () configured to expose inner surfaces () of cylinder bores (), and mask an inner surface () of a crankcase (). The mask body () includes a main body portion (), a sealing member () and a biasing member (). The main body portion () is configured to stretch and contract, and includes a first tubular member () and a second tubular member () configured to have an insert structure at least part of which is slidable along an axial direction. The main body portion () can stretch and contact in a state where at least one end in the axial direction thereof contacts an inner surface of a cylinder block (). The sealing member () is interposed between sliding surfaces of the first tubular member () and the second tubular member (). The biasing member () is configured to resiliently bias the first tubular member () and the second tubular member () in a stretching direction of the main body portion ().
