Problems solved by technology

Therefore, strengthening treatment such as heat treatment must be performed on the reinforcing plate in advance in order to improve the wear resistance of the reinforcing plate, which is one cause of an increase in production cost
In addition, since the reinforcing plate is subjected to strengthening treatment such as heat treatment, etc., the reinforcing plate is deformed, and it is understood that in this case, the ability to fit the reinforcing plate into the slit is reduced

Abstract

The present invention provides a plastic movable guide having excellent noiselessness and assembling ability and capable of reducing production cost. On the pivoting front end side of the guide body 101, a plunger accommodating portion 101B, which a plunger of the tensioner can contact and press, is provided, and a reinforcing plate 108 is provided in a slightly recessed manner. The plunger receiving portion 108 is such that the reinforcing plate 108 does not protrude from the edge of the opening in the slit.

Description

technical field [0001] The present invention relates to a plastic movable guide for transmissions used by mounting them rotatably around an axis such as tension rods, slides, etc. , driven side sprockets and chains wound on these sprockets and circulated to transmit power from the driving side to the driven side transmission, or the movable guide is used to pass the driving side pulley, driven Side pulleys and a belt that circulates around these pulleys transmit power from the driving side to the driven side of the transmission. Background technique [0002] Engines, drives, etc. typically include transmissions that transmit power via chains, belts, etc. In such transmissions that have been used, a movable guide with a sliding function is provided, which can apply a suitable tension to the circulating chain or belt in sliding contact with it, and prevent vertical vibration and vibration of the running chain or belt. Lateral vibration. This movable guide is connected to th...
