Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
233 words
An electrically and manually operable exterior storage type mirror for a vehicle comprising: a base for mounting said storage type mirror to a body of said vehicle; a mirror housing rotatably coupled to said base; a transmission gear rotatably coupled to said base and provided between said base and said mirror housing; a first clutch means provided between one surface of said transmission gear and said mirror housing, said first clutch means comprising convex parts on said one surface of said transmission gear, concave parts on said mirror housing engaging with said convex parts and spring means for causing said convex and concave parts to be in resilient engagement; a second clutch means provided between another surface of said transmission gear and said base, said second clutch means having an engaging force greater than an engaging force of said first clutch, said second clutch means comprising convex parts on said another surface of said transmission gear, concave parts on said base engaging with said convex parts and spring means for causing said convex and concave parts to be in resilient engagement; and a means fixed to said mirror housing and provided within said mirror housing for rotating said transmission gear when electric power is applied to said means; and wherein the height of said convex parts of said first clutch is less than a height of said convex members of said second clutch.
Claim 2
Dependent Claim
