1. A linear guideway, comprising:
a track having two lateral surfaces respectively arranged on two opposite sides thereof and an upper surface that is connected to the two lateral surfaces;
a sliding module slidably disposed on the track along a sliding direction, wherein the sliding module includes:
a slider having a base portion and two lateral wing portions that respectively extend from the base portion, wherein inner sides of the two lateral wing portions respectively face toward the two lateral surfaces;
two circulation seats respectively assembled to the two lateral wing portions and respectively corresponding in position to the two lateral surfaces; and
an upper dustproof member including:
a connection segment corresponding in position to the base portion of the slider; and
two floating dustproof segments respectively connected to two opposite sides of the connection segment, wherein each of the two floating dustproofing segments has a carrying bar and at least one rib that is connected to the carrying bar, and wherein, in each of the two floating dustproofing segments, the carrying bar has two end portions respectively protruding beyond two end surfaces of the slider, and each of the two end portions has a bevel arranged away from the at least one rib; and
two end caps respectively assembled to the two end surfaces of the slider and slidably disposed on the track, wherein each of the two end caps has two tolerance slots recessed in a surface thereof arranged adjacent to the corresponding end surface, and wherein, in each of the two end caps, slot openings of the two tolerance slots are arranged away from each other along a width direction perpendicular to the sliding direction, and each of the slot openings has a stopping corner and a matching corner that faces toward the stopping corner along a thickness direction perpendicular to the sliding direction and the width direction;
wherein the bevels of the end portions of the upper dustproof member are respectively inserted into the tolerance slots of the two end caps, and each of the end portions and the corresponding end cap have a tolerance gap therebetween, so that when the at least one rib of each of the two floating dustproof segments abuts against the upper surface of the track, a slanting surface of each of the bevels abuts against the matching corner of the corresponding tolerance slot, and each of the end portions is deformable toward the corresponding tolerance gap.

10. An upper dustproof member of a linear guideway, comprising:
a connection segment; and
two floating dustproof segments respectively connected to two opposite sides of the connection segment, wherein each of the two floating dustproofing segments has a carrying bar and at least one rib that is connected to the carrying bar, and wherein, in each of the two floating dustproofing segments, the carrying bar has two end portions each having a bevel arranged away from the at least one rib;
wherein, when the bevels of the end portions of the upper dustproof member are respectively inserted into four tolerance slots of two end caps, each of the end portions and the corresponding end cap have a tolerance gap therebetween, so that a slanting surface of each of the bevels abuts against the corresponding tolerance slot, and each of the end portions is deformable toward the corresponding tolerance gap.
