Claim:
A riding simulation system for providing an operator with a pseudo-experience of running conditions of a motorcycle by displaying scenery seen to the rider as a video image on a display based on the operating condition of operation by the operator, said riding simulation system comprising: a steering handle mechanism gripped and operated by the operator; a step mechanism comprising a brake pedal and a gear change pedal which are operated by the feet of the operator; a connection shaft for connecting said steering handle mechanism and said step mechanism to each other, said connection shaft provided to be extendable and contractible along the axial direction thereof; and a frame body having: a cylindrical portion, and at least two main frames having upper portions that are directly attached to the cylindrical portion and lower portions that are connected via a connection frame, the at least two main frames having curved shapes, wherein all portions of the at least two main frames are disposed forwardly with respect to the steering handle mechanism, wherein said steering handle mechanism is mounted at an upper portion of the cylindrical portion, and the connection shaft is disposed midway along the connection frame which extends orthogonally with respect to the lower portions of the at least two main frames, further comprising a vibrator for a dummy engine vibration, a taper surface portion formed at an inner circumferential surface of a steering handle pipe constituting said steering handle mechanism, said taper surface portion gradually decreasing in diameter from the side of an end portion of said steering handle pipe; and a bracket having an engaging portion for engagement with said end portion of said steering handle pipe, having an outer circumferential surface gradually decreasing in diameter from the side of said engaging portion, and being inserted into said taper surface portion while holding said vibrator; wherein the bracket includes a pair of brackets, wherein each of the brackets includes a recess on an inner surface thereof, and when the brackets are mated together, the recesses of the mating brackets form a space in which the vibrator is disposed wherein recesses have flat inner faces that oppose each other for engaging with left and right flat sides of the vibrator.
