    摘要： The present invention provides a timing chain drive device which has high mechanical strength of the timing chain contact surface and small sliding resistance, and which, even when being brought into contact with a timing chain running at high speed, is difficult to wear. A first chain guide and a second chain guide, which give tension to a timing chain so as to prevent the timing chain from being slackened, are arranged, and a plurality of rollers, each of which is supported by a rolling element, are arrayed in each of the first chain guide and the second chain guide so as to be brought into contact with the timing chain.

    摘要： An object is to reduce various losses occurring in a speed-reduction/differential gear apparatus for electric vehicles including a planetary-gear speed reducer and a differential device, thereby improving transmission efficiency of the driving force and increasing travel distance of the electric vehicle per battery charge. A speed-reduction/differential gear apparatus for electric vehicles includes a planetary-gear speed reducer and a differential device. A planetary gear mechanism in the speed reducer includes a speed-reducer-side carrier which has its inner diameter surface supported by a speed-reducer-side carrier support bearing. The invention provides proper mesh between in the pair of engaging teeth, leading to decrease in loss torque.

    摘要： A chain guide and a chain tensioner device using the chain guide. A roller, brought into contact with a chain, comprises a support shaft supported by an opposing guide base provided along the running direction of the chain, and roller bearings each having a steel outer ring on the outer peripheral surface of the support shaft so as to be brought into contact with the chain. The roller is also configured to be assembled by inserting opposite ends of the support shaft into support recesses on facing wall surfaces of the guide base. The roller, has a vibration damping material between the support shaft and the support recess of each of the plate members.

    摘要： Provided are a gear and a gear drive unit which allow oil film formation to a sufficient degree between tooth surfaces of gears rotating at high-speed and which help to prevent generation of pitting, abrasion, and prevent scoring, temperature rise, and wear to thereby achieve an improvement in terms of durability. A tooth surface is provided with a multitude of minute recesses arranged at random, in which an axial surface roughness parameter Ryni of the surface thus provided with the recesses is set to a range: 0.8 μm≦Ryni≦2.3 μm. As a result, the tooth surface is endowed with a high oil film formation performance, and it is possible to attain a long service life even under a low-viscosity/thin-lubrication condition in which the oil film is extremely thin.

    摘要： There is provided a rocker arm of a kind in which even though the rocker arm is manufactured by the use of a press working technique the arm width can be minimized while the flat outer surface region of a required width is secured on an outer surface of the connecting wall, thereby contributing to reduction in size and weight of the rocker arm. This rocker arm is capable of being driven by a cam for selectively opening and closing a valve of an internal combustion engine. This rocker arm includes an arm body prepared by bending a single plate material to represent a generally inverted U-shaped section including opposite side walls and a connecting wall bridging between the opposite side walls. A roller engageable with the cam is rotatably mounted on a portion of the arm body generally intermediate of the length thereof. A valve drive element is mounted on one end of the arm body for driving the valve, while an end portion of the connecting wall adjacent the other end of the arm body is formed with an internally helically threaded hole for threadingly receiving therein an externally helically threaded pivot member. An outer chamfered corner delimited between an outer surface of the connecting wall and an outer surface of each of the opposite side walls and formed by bending is deformed to represent a plastically deformed portion so formed by means of a plastic deformation technique that the outer chamfered corner represents a small radius of curvature R.
