Problems solved by technology

[0007] However, since the vehicle frame, the engine hanger, the swing arm pivot, and the like are collectively arranged close to the crankcase on the rear surface portion of the crankcase, in the vehicle speed sensor mounting structure described in Patent Document 1, care must be taken when assembling the engine. Sometimes the frame and the vehicle speed sensor do not interfere, and once the vehicle is assembled, it may become difficult to disassemble or maintain the vehicle speed sensor

Abstract

Provided is a vehicle speed sensor mounting structure for mounting a vehicle speed sensor by means of a simple configuration to an area in which maintenance is easily performed while protecting the vehicle speed sensor. A vehicle speed sensor (77) is secured to a crank case (64) by fastening the vehicle speed sensor (77) together with a protector (83), which covers the upper section of the vehicle speed sensor (77), by means of a fastening member while the axis (O) of the roughly cylindrical main body (78) of the vehicle speed sensor (77) is tilted a prescribed angle ([theta]) towards the rear side of the vehicle body when viewing the vehicle from the side and on a position which is on the upper side of a sub-shaft (35) and the rear side of a shift drum (150) with respect to the vehicle body. By inserting the main body (78) of the vehicle speed sensor (77) into a through hole (73) formed on the crank case (64), the detection unit (78a) of the vehicle speed sensor (77) faces the tip of the tooth of a second-speed driven gear (G2). The through hole (73) through which the main body (78) is inserted and a fastening hole (74) through which the fastening member (81) is inserted are disposed on a fastening base (72) formed on the crank case (64). The fastening hole (74) is disposed on the outside in the vehicle width direction of the through hole (73).

Description

technical field [0001] The present invention relates to a vehicle speed sensor installation structure, in particular to a vehicle speed sensor installation structure for installing a vehicle speed sensor on a crankcase of an engine. Background technique [0002] Conventionally, in order to detect a vehicle speed based on a rotational speed of a counter shaft of a transmission, a structure in which a vehicle speed sensor is attached to a crankcase of an engine is known. [0003] Patent Document 1 discloses a vehicle speed sensor installation structure in which the detection portion of the vehicle speed sensor is directed toward the front of the vehicle body, the detection portion is opposed to the tooth top of the gear that rotates integrally with the countershaft of the transmission, and is located on the wall surface of the crankcase on the rear side of the vehicle body. Install the vehicle speed sensor. [0004] prior art literature [0005] patent documents [0006] Pa...
