roller

The present invention relates to a sash roller for a window system having a pieceless detachable structure. Each of left and right brackets (5, 5') of an outer case (1) are divided into upper and lower brackets (5a, 5b), and the lower brackets (5b) are formed to be as thick as an existing bracket. Thus, the sash roller (100) can be stably supported without deformation or damage even under external shock or high load. The upper brackets (5a) are formed to be thin to support the outer case (1) and stably exhibit elasticity, wherein vertical long holes (11, 11') provided in upper and lower portions of left and right sides of the outer case (1) are also formed by taking into account the thicknesses of the upper and lower brackets (5a, 5b). The upper brackets (5a) are formed as elastic pieces (51) which are formed by long extending lower portions and bending the same outward and have locking pieces (52). Thus, the elastic action of the elastic piece (51) causes the sash roller (100) to be easily assembled and mounted on or separated from a fitting hole (8') in a one-touch manner without a piece. Therefore, when the sash roller (100) is assembled to a window frame (F), the same can be assembled quickly and easily in the one-touch manner, and when the sash roller (100) assembled to the window frame (F) is separated from the window frame (F), the sash roller can be separated by simply pushing the elastic piece (51) with a tool such as a screwdriver or an awl, so that convenience in construction can be maximized, the reliability can be improved, and the cost of production including construction costs can be greatly reduced. 본 발명은 무피스 착탈구조를 가진 창호용 호차에 관한 것이다. 구성에 있어서 본 발명은, 아웃케이스(1)의 좌우 브래킷(5)(5') 각각을 상하 브래킷(5a)(5b)으로 이원화시켜 하 브래킷(5b)은 상기 종래의 브래킷 두께와 동일하게 두껍게 형성함으로서, 호차(100)가 외부적 충격이나 고 하중에도 변형이나 파손없이 안정적으로 지탱할 수 있게 하고, 상 브래킷(5a)은 아웃케이스(1)를 지지하면서도 안정적으로 탄성을 발휘하도록 얇은 두께로 형성
