Claim 0:
1. A linear guideway, comprising:
a track having two lateral surfaces respectively arranged on two opposite sides thereof;
a sliding module slidably disposed on the track along a sliding direction, wherein the sliding module has two end surfaces and 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; and
two circulation seats each having an one-piece structure, wherein the two circulation seats are respectively assembled to the two lateral wing portions and respectively correspond in position to the two lateral surfaces, and wherein each of the two circulation seats includes:
two turning portions respectively disposed on the two end surfaces of the slider;
a middle retaining portion having a two-stepped structure parallel to the sliding direction, wherein the two-stepped structure includes a connection bar and a limiting bar that is connected to the connection bar, and wherein the connection bar is connected to and arranged between the two turning portions, and a distance between two lateral surfaces of the connection bar increases along a direction away from the limiting bar; and
two lateral retaining portions connected to and arranged between the two turning portions, wherein the two lateral retaining portions are respectively located at two opposite sides of the middle retaining portion; and

two end modules respectively assembled to the two end surfaces of the slider, wherein each of the two end modules covers one of the two turning portions of each of the two circulation seats, and the two end modules are slidably disposed on the track,
wherein, in each of the two circulation seats, each of the limiting bar of the middle retaining portion and the two lateral retaining portions has an injection groove formed on a boundary surface adjacent to the track, and the injection groove of the limiting bar is spaced apart from the injection groove of each of the two lateral retaining portions by a same distance.
