AUTOMATIC TENSIONER
Document Type and Number:
Japanese Patent JP3411101
Kind Code:
B2
Abstract:
PURPOSE: To provide a structure which is compact and has a large vibration preventing effect of a timing belt.
CONSTITUTION: A pulley 5 pivoted on an oscillating member 18 is pressed onto a timing belt 2 by elasticity of a tension applying spring such as a torsional coil spring 28. By means of a damper device 34, displacement of the pulley 5 in the retracting direction from the timing belt 2 is gradually carried out. A leakage gap between the inner circumferential face of a cylinder sleeve 39 constituting the damper device 34 and the outer circumferential face of a piston fitted inside the cylinder sleeve 39 is regulated within the predetermined range.
