Abstract: A ball screw device or linear motion guide device has a seal member preventing dust and dirt from entering into a movable member of a linear motion guide device and seals out fine dust, dirt or like by surely contacting a seal to a shaft member without providing a large margin to the seal. The seal member includes a body portion mounted to the movable member and a lip portion contacting an outer portion of the shaft member, the lip portion has an oblique surface having an axial section inclining with respect to its axial direction, the body portion has an urging member urging the lip portion in a diameter direction of the shaft member and a reinforcing portion reinforcing the body portion. The urging member is located on the reinforcing portion side than the tip end of the lip portion in the axial sectional shape of the lip portion.
