SPEED SENSOR INSTALLATION STRUCTURE IN A VEHICLE

摘要

In a vehicle in which: power transmission means for transmitting power from a power source to an axle of a rear wheel is accommodated in a swing arm that is swingably supported on a vehicle body frame; a final gear of a reduction gear train constituting a part of the power transmission means is fixed to the axle; and a pickup forming a vehicle speed sensor together with a detected portion that is provided on the final gear is mounted on the swing arm so as to face the detected portion, the detected portion (108) is provided on one of opposite axial end surfaces of the final gear (103) and the pickup (109) is mounted on the swing arm (22A) so as to extend parallel to an axis of the axle (21). Accordingly, it is possible to reduce the size of the swing arm by preventing an increase in a length in a front-and-rear direction of the swing arm even when the pickup is arranged in the swing arm.
