摘要

PURPOSE: An electronic throttle device is provided to automatically open and close a throttle valve, to reduce the size of a product by making a limp home open positioning convenient via an adjusting member, and to improve the performance, stability, assembling efficiency and productivity of the product. CONSTITUTION: An electronic throttle device(30) comprises a limp home member(60) consisting of a limp home lever(61) and a limp home spring(62), an adjusting member consisting of a unified adjusting screw(63) and flowing a limited amount of air in the idle state, a throttle position sensor(46) for generating electrical signals by sensing the rotational degree of a throttle valve(45), a cover(70) for covering the mounting space, and a connector(71) for connecting an external power supply with the electric signals.
