  • Patent number: 4487282
    Abstract: A parking lock system for a three-wheeled vehicle having front and rear vehicle bodies interconnected so as to be capable of rolling relative to each other. The parking lock system comprises a first engagement member mounted on one of the vehicle bodies so as to be rollable substantially integrally therewith, and a second engagement member provided for the other of the vehicle bodies so as to be rollable substantially integrally therewith and engageable with the first engagement member in at least one predetermined relative position only, such engagement serving to lock the relative rolling. The system also includes a wheel lock mechanism for locking the rotation of at least one road wheel of the vehicle, a cable member adapted to be pulled to actuate both the second engagement member and the wheel lock mechanism; and an engagement assuring mechanism for assuring the engagement between the first and second engagement members while the cable member is pulled.
