A saddle-type vehicle has an engine-fastening structure which stabilizes a seating face contact between a collar and a vehicle body frame on one side, and between the collar and an engine on the other side. The vehicle includes a vehicle body frame having an engine-supporting portion, and an engine block having a female threaded portion formed therein for alignment with the engine-supporting portion. The collar is interposed between the engine-supporting portion and the engine block. The engine-supporting portion of the frame, the collar and the engine side female threaded portion are fastened together by a bolt. A gap is provided at least at locations between the collar and the bolt which oppose a boundary between the collar and the engine-supporting portion, and another boundary between the collar and the engine side female threaded portion.
