An exterior member such as a shroud, for a saddle-type vehicle including a head pipe and a main frame extending rearward from the head pipe, has a hook member formed on an inner side thereof. The hook member is configured for being engaged onto the main frame such that the exterior member is supported by the main frame. The exterior member is locked to the vehicle by engaging the hook member onto the main frame, thereby supporting the exterior member on the main frame. Such arrangement enables the exterior member to be affixed to the frame with a simple structure, without detrimentally affecting the external appearance of the vehicle.
