Abstract

PURPOSE:To prevent wear and unusual noise from being generated between sleeves and the end of a spring by rotating the sleeve on the side of a throttle lever, which is one out of two sleeves supporting the both ends of a throttle valve return spring, monolithically with a throttle valve shaft. CONSTITUTION:The both ends of a throttle valve return spring 10 are supported by both No.1 sleeve 17 and No.2 sleeve 18. Here, when a throttle valve shaft 6 is rotated, the end section of the throttle valve return spring 10 on the side of a throttle lever 9 is displaced in rotation accompanied with the rotation of the throttle lever 9 so as to press No.2 sleeve 18 into contact with the throttle valve shaft 6 by spring force, no relative slide between No.2 sleeve 18 and the end section of the spring 10 supported thereby will never take place. On the other hand, the end section of the spring 10 supported by No.1 sleeve 17 only presses No.1 sleeve 17 onto a bearing housing 4 so as to be hardly displaced, no relative slide between No.1 sleeve 17 and the end section of the spring 10 will never take place either, thereby preventing both unusual noise and abnormal wear from being generated.
