Vehicle speed sensor mounting structure.

Abstract

In a state that an axis line O of an approximately cylindrical main body 78 is inclined by a predetermined angle θ toward the vehicle body rear side when viewed from the side of the vehicle body, a fastening member 81 is used to fasten together with a protector 83 which covers an upper part of a vehicle speed sensor 77, thereby the vehicle speed sensor 77 is fixed to a crankcase 64 at a position on the vehicle body upper side of a countershaft 35 and also on the vehicle body rear side of the shift drum 150. The main body 78 of the vehicle speed sensor 77 is inserted into a through hole 73 formed on the crankcase 64, by which a detection part 78a of the vehicle speed sensor 77 is constituted so as to oppose to the tip of a second driven gear G2.
