    • PROBLEM TO BE SOLVED: To provide a motion guide device capable of properly maintaining pressure acting on a seal lip regardless of a change in clearance for inserting an inner seal. SOLUTION: In this motion guide device 10 having a track member 11, a moving body 12 installed on the track member 11 in a state relatively movable in the lengthwise direction, a large number of rolling bodies 16 interposed between the track member 11 and the moving body 12 and the inner seal 15 being interposed between the track member 11 and the moving body 12 in a state integrally movable with the moving body 12 to the track member 11 and arranging the seal lip 41 in the lengthwise direction for sealing a load rolling traveling passage R of the rolling bodies 16 to an external part, a support means 42 having a spring constant smaller than the seal lip is arranged between the inner seal 15 and the moving body 12.
    • 要解决的问题:提供能够适当地保持作用在密封唇上的压力的运动引导装置,而不管插入内部密封件的间隙的变化。 解决方案:在具有轨道构件11的运动导向装置10中,以沿长度方向相对移动的状态安装在轨道构件11上的移动体12,多个滚动体16插入在轨道构件11和移动 主体12和内密封件15以与移动体12一体移动到轨道构件11的状态插入在轨道构件11和移动体12之间,并且将密封唇41沿长度方向布置,以密封载荷滚动行进 滚动体16的通道R到外部,具有小于密封唇的弹簧常数的支撑装置42设置在内密封件15和移动体12之间。
