Abstract

In a small vehicle (1) provided with a power unit (5) including an internal combustion engine 2 and a power transmission system (3) and swingably attached to a body frame (4) below a seat (6), the wiring configuration for the throttle body in the small vehicle (1) includes a throttle body (52) disposed between the power unit and seat, an opening sensor (68) for detecting the degree of throttle opening, provided at an end of a throttle valve shaft (64) aligned along the width direction of the vehicle, an actuator (70) for controlling the throttle body, attached to the throttle body in the vicinity of the opening sensor, and a first wiring coupler (80) of the opening sensor and a second wiring coupler (81) of the actuator, the first and second wiring couplers (80, 81) being separately attached in the same front / rear direction so as to intersect with respect to the throttle valve shaft.

Description

technical field [0001] The present invention relates to a wiring structure to a throttle valve area of ​​a small vehicle that swingably supports a power unit. Background technique [0002] In the past, the wiring to the throttle area of ​​a small vehicle with a power unit swinging support has adopted the following structure: a control unit that integrates multiple functions of an actuator and a sensor is integrally installed in the throttle area, and a single wiring coupler is used. (Japanese: wiring カプラ) to connect with the outside. [0003] For example, as shown in the following patent document 1, a single wiring coupler facing the vehicle width direction in a manner perpendicular to the intake passage of the throttle section is provided on the upper part of the throttle section, and an external wiring coupler is connected to the single wiring coupler. coupler. [0004] Patent Document 1: Japanese Patent No. 3975065 ( image 3 , 4 、5) [0005] However, in the case show...
