    摘要： A linear motion guide device having a long scale can be easily manufactured, and there is provided a motion guide device capable of preventing thin and long-scaled support member and escape passage constituting member from being flexed and preventing an inner periphery guide section constituting member from being opened. Support members 11, 12, 13 for preventing rolling members from coming off from loaded rolling member rolling passages 4d, 4d at a time of removing a movable block 2 from a track rail 1, escape passage constituting members 14, 14 constituting escape passages and the inner periphery guide section constituting members 15a, 15b constituting inner periphery guide section for direction changing of the rolling members are formed of resin so as to be respectively independent from the block body 4 and from each other, these members can be manufactured by preliminarily calculating respective shrinkage cavities of the support members 11, 12, 13, the escape passage constituting members 14, 14 and the inner periphery guide section constituting members 15a, 15b. As a result, the long and thin support members 11, 12, 13 and escape passage constituting members 14, 14 can be prevented from being flexed, and the inner periphery guide section constituting members 15a, 15b can be also prevented from being opened.
