First Claim
1. A tilt angle sensor layout structure for a vehicle, the vehicle comprisinga vehicle body,a steering mechanism provided at a front portion of the vehicle body and including a handlebar and a steering shaft,a vehicle body frame comprising a plurality of frame members which support said steering mechanism,at least three wheels operatively attached to the vehicle body frame,a power unit having an engine supported on said vehicle body frame,a fuel tank supported on said vehicle body frame,a fuel injection system for supplying fuel from the fuel tank to said engine, anda tilt angle sensor operatively attached to a portion of said vehicle body frame, wherein:
- the tilt angle sensor is operable to detect a tilt angle in a left-right direction of said vehicle body,the plurality of frame members cooperate to define a substantially triangular closed frame loop,the plurality of frame members comprise an upper frame member which extends from an area proximate a front one of said wheels rearwardly to an area proximate a rear one of said wheels, said upper frame member having an uppermost portion,said tilt angle sensor is disposed on said substantially triangular closed frame loop at a position below the uppermost portion of said upper frame member and spaced away from said fuel tank; and
wherein the plurality of frame members of the vehicle body frame comprises;
a left-right pair of lower frames supporting a lower portion of the power unit;
a left-right pair of upper frames attached to upper portions of the lower frames so as to surround the power unit in side view,a left-right pair of front frames providing connection between front upper portions of the upper frames and front end portions of the lower frames,a left-right pair of front connection frames providing connection between the front frames and the upper frames.

Abstract
In a saddle-type vehicle having at least three wheels, a tilt angle sensor layout structure is provided which ensures that a tilt angle sensor is minimally influenced by a centrifugal force or vibration of a vehicle body while the vehicle is turned, and the tilt angle sensor is protected against flying stones and the like. The vehicle includes an engine, and a fuel injection system for supplying fuel from a fuel tank to the engine, with a steering mechanism including a steering shaft provided on the front side of the vehicle body. A plurality of frame members constituting the vehicle body frame supporting the steering mechanism are connected in the shape of a frame loop in vehicle side view, and the tilt angle sensor for detecting the tilt angle in the left-right direction of the vehicle body is attached to the loop-shaped portion of the vehicle body frame.
