Abstract

PURPOSE:To permit the sliding of the cam chain for engine to be favourably absorbed by installing a damper rubbr between the slipper extending along the cam chain and a damper arm and setting the damper arm in forward tiltable form through a spring. CONSTITUTION:In front of the tensioner body 1 which is formed through press- work for a sheet metal, the slipper 3 which extends along a chain 2 and the damper arm 5 which supports the sipper 3 through a pair of damper rubbers 4 in front and in rear are axially supported by a common shaft 6. The slider 8 which is supported onto one side by a spring 7 is installed in front of the body 1, and the slider 8 is fixed by the screws 9 on the top edge side and on the rear edge side, permitting the sliding by the spring 7 to be restrained. Further, the slider 8 and the arm 5 are connected with each other through an intermediate ring 10, and the link 10 is tilted to the standing-up side through the leftward movement of the slider 8 due to the spring 7, and the arm 5 is pushed and advanced with the slipper 3, permitting the following to the loosening of the chain 2.

In this case, the spring plate (1) consists of a spring plate having a layer on the front surface, and the spring d acts between both ends of the spring plate to give it a forward bulge that curves in an arcuate manner. In such a slipper, the sliding movement of the skeleton chain should be absorbed by the elasticity of the slipper itself.
This has the disadvantage that it is difficult to obtain good absorption.

より前方に傾動自在として成る。The object of the present invention is to obtain a device that does not have such inconveniences, and is provided with a slipper extending along the chain on the front side of the main body for practicing tension, and a spring on the back side of the slipper. In a slipper that can be pushed forward by a spring, the slipper is provided with a damper arm on the back side that supports the slipper via a damper collar, and the arm can be tilted forward by the spring.

A pair of screws (91 (9) on the front end side and the rear end side) are used to fix the slider (8) on the main body (1) as appropriate to prevent sliding due to the spring (7). The arms (5) are connected to each other by an intermediate link oil, and thus the slider (7) of the slider (8)
According to the drawing according to ), by sliding to the left, the link Q (I is tilted to the upright position and the arm (51t - the slipper (3)

の効果を有する。To explain its operation, if each screw (91) is tightened, the skeleton slider (81 is fixed and does not slide due to the spring (7). (5) and the slipper (3) in front of it are stopped from moving forward by the spring (7) and remain in the stopped position, but next time when the chaino (2) becomes loose, the screw (
9) This is to temporarily loosen 19), and thus the slider (
8) presses the arm (5) through the link frame which is allowed to slide by the spring (7), and the crease slipper (3) is pushed by this and loosens the chaino (2). Accordingly, the chain moves forward to bring it into a predetermined tensile state, but during such operation, the sliding movement of the chino (2) passes through the slipper (3) to the damper rubber (4) on its back side. To explain further, the wrinkled slipper (3) can be made of a relatively rigid plate material, and the sliding of the chino (2) acting on it is caused by its dorsal side. There is no inconvenience caused by the slippers being absorbed by the wrinkled rubber (4) between the damper arm (5).In this way, according to the present invention, the slippers that extend along the chest are attached to the dorsal damper that supports them via the damper arm rubber. It is a type in which the pressing force of the spring is applied by placing the arm 1 in place, and the sliding movement 4 of the chino.
1. It acts on the damper brim through the slit and absorbs it well, thus giving the slipper a relatively high rigidity without the above-mentioned disadvantages of the conventional slipper in which the damper is absorbed by itself. It has the effect of increasing the number of formulations used.
