Abstract:
A structure for mounting an angle sensor on a side surface of a multicylinder engine of a motorcycle, wherein said multicylinder engine has a right side surface and a left side surface which confront and are horizontally attached to a left main frame and a right main frame extending rearwardly and slanting downwardly from a head pipe, and wherein said structure for mounting the angle sensor comprises:a timing transmission chamber mounted on the engine, and extending along one end of a valve driving camshaft in a direction perpendicular to an axis of said valve driving camshaft; a timing transmission mechanism for transmitting rotation of a crankshaft to said valve driving camshaft; a timing transmission chamber cover for covering an opening in said timing transmission chamber, the timing transmission chamber cover being exposed in a direction perpendicular to the axis of the valve driving camshaft and to an outside of one of the frames; a pulsar rotor of the angle sensor, said pulsar rotor being supported by a driven gear and being detachably fixed to said end of said valve driving camshaft of said timing transmission mechanism; and a cam pulsar of the angle sensor, said cam pulsar being disposed inside said timing transmission chamber and supported by said timing transmission chamber cover so as to face said pulsar rotor, and said cam pulsar being disposed lower than and inward from one of said main frames, so that in a mounted state, said cam pulsar can be observed from either an upper side or a lower side of the motorcycle.
