    • Friction reducing units are integrally configured in a tensioner arm and a chain guide that are disposed at both sides of a timing chain to make contact with the timing chain, respectively to increase the thickness of the oil film, such that it is possible to improve durability of an entire timing chain system while preventing noise from being generated by reducing a friction loss generated on each of contact surfaces of the tensioner arm and the chain guide and prevent fuel efficiency of the vehicle from being deteriorated.Provided is a friction reducing device of a timing chain for a vehicle in a timing chain system including a tensioner arm and a chain guide disposed at both sides of a timing chain interconnecting a crank sprocket mounted a crank shaft and a cam sprocket mounted on the cam shaft so as to transfer a rotational force of the crank shaft to a cam shaft, respectively to prevent the timing chain from being separated while reducing vibration of the timing chain, wherein the tensioner arm and the chain guide further include first and second friction reducing units integrally formed, respectively in order to reduce a friction loss by increasing the thickness of an oil film between each of contact surfaces that make sliding-contact with the timing chain.
    • 摩擦减少单元一体地构造在分别布置在正时链的两侧以与正时链接触的张紧器臂和链条引导件中,以增加油膜的厚度,使得可以提高耐久性 的整个正时链系统,同时通过减少在张紧器臂和链条引导件的每个接触表面上产生的摩擦损失来防止噪声产生,并且防止车辆的燃料效率劣化。 本发明提供一种正时链系统中的车辆正时链的减摩装置,包括:张紧器臂和链条引导件,其布置在连接安装在曲柄轴上的曲柄链轮和安装在凸轮上的凸轮链轮的正时链的两侧 以便分别将曲柄轴的旋转力传递到凸轮轴,以防止正时链条分离,同时减少正时链条的振动,其中张紧器臂和链条引导件还包括第一和第二摩擦减小单元 分别一体地形成,以通过增加与正时链滑动接触的每个接触表面之间的油膜的厚度来减小摩擦损失。

    • A lower body sauna device includes a heat chamber that is adapted to enclose the lower body of a user, and an infrared heater provided inside the heat chamber. The heat chamber includes an elliptically shaped body opening that is adapted to fit the waist of the user, and the size of which is adjustable. The top slab includes a sliding top panel and a fixed top panel. The body opening includes a first elliptical half opening provided on the sliding top panel, and a second elliptical half opening provided on the fixed top panel. The sliding top panel is adapted to slide to an away from the fixed top panel so that the size of the body opening is adjusted.
    • 下体桑拿装置包括适于封闭使用者的下身的加热室和设置在加热室内部的红外线加热器。 加热室包括椭圆形主体开口,其适于装配使用者的腰部,并且其尺寸是可调节的。 顶板包括滑动顶板和固定顶板。 主体开口包括设置在滑动顶板上的第一椭圆形半开口和设置在固定顶板上的第二椭圆形半开口。 滑动顶板适于滑动到远离固定顶板,从而调整主体开口的尺寸。
