Apparatus for opening and closing louver
摘要:
A wiper for wiping a windshield is concealed by a louver when the wiper is not used. When the engine needs to be cooled, however, the louver is moved such as to open a wiper housing portion. Thus, the engine room is opened through the wiper housing portion, whereby cooling of the engine is promoted.
