Abstract: Disclosed is an arrangement structure for a sensor to be mounted to an engine of a vehicle, wherein the engine is arranged in an engine compartment 2 of the vehicle in a posture allowing a crankshaft 8 of the engine to be oriented in a widthwise direction of the vehicle. The arrangement structure comprises a driveshaft 50 arranged along a vehicle-rearward lateral surface of the engine 1 facing in a rearward direction of the vehicle, to rotatably drive a front wheel, and a flange section 28a provided as a joining section between two members (12, 15) constituting the engine 1, to protrude in the rearward direction of the vehicle and at a height position below that of the driveshaft 50, wherein the sensor 42 is mounted to the vehicle-rearward lateral surface of the engine 1 at a height position located above the flange section 28a and in overlapping relation with the driveshaft 50 when viewed from a rear side of the vehicle.
