A changeover valve includes: a valve body portion that closes an opening formed at a switching position of an exhaust flow path; a fixing portion that rotatably fixes the valve body portion; a first raised portion protruding at one of a flow path forming portion and the fixing portion; a cushion portion; a second raised portion protruding at the valve body portion; and a biasing portion that biases the valve body portion. The first raised portion has an inclined portion inclined relative to a valve closing direction and the second raised portion has an inclined portion inclined relative to the valve closing direction. Both of the inclined portions are contactable with each other at the time of valve closing.

A product design CAD data reconstruction unitreconstructs product design CAD data used for product evaluation regarding an initial design so as to fulfill restrictive conditions obtained from the product evaluation based on a product structure for the initial design. The reconstructed product design CAD data is stored in a product design CAD data database. Upon reception of a corrected design obtained by correcting the initial design, the product design CAD data for the initial design is read from the product design CAAD data database, and the product design CAD data is corrected along a design surface of the corrected design.
