At the end of the yoke 110 facing the front plate of the drawer, a screw hole 120 for screwing with the angle adjusting pin 700 is formed.

That is, the screw hole 120 is formed on the bottom surface of the yoke 110 in which the guide rail 220 is fitted.

A stopper 140 is formed at one end in the longitudinal direction of the base 100 to restrict reverse movement of the drawer rail 300 due to contact interference when the drawer is completely closed.

Here, the base 100 can be molded integrally by injection molding a synthetic resin such as engineering plastic into a mold.

The guide rail 200 is coupled to one side of the base 100 to support and disperse the load of the drawer and to provide a smooth running surface (sliding surface) to the sliding carriage 400 to perform the sliding movement of the drawing rail 300 Guide.

One end portion in the longitudinal direction of the guide rail 200 is connected to one end portion of the yoke 110 in the longitudinal direction by a pin and the other end portion of the guide rail 200 is connected to the pin (Not shown).

That is, the guide rail 200 is mounted on the yoke 110 so that the free end of the guide rail 200 ascends and descends according to the tightening and unclamping operation of the angle adjusting pin 700, and is installed so as to be inclined with respect to the base 100.

The upper part of the guide rail 200 can be formed by extruding the guide rail 200 in the form of an aluminum profile. The upper part of the guide rail 200 is in contact with a ball or a roll of the sliding carriage 400, So that each side can be formed into an arc shape, that is, a groove shape, toward each center.

The drawing rail 300 is formed to surround the guide rail 200 and is folded or expanded with respect to the base 100 while sliding along the longitudinal direction of the guide rail 200.

When the holder 500 is coupled with the fixing protrusion 520 of the holder so that both end portions of the holder 300 are perpendicular to the longitudinal direction of the drawing rail 300, Is formed.

For example, the lead-out rail 300 may be formed in an '?' Shape when viewed from the front.

The fixing groove portion 310 is formed to have a height higher than the thickness of the fixing protrusion 520 in order to prevent the shape of the holder 500 made of synthetic resin from being deformed due to the twist deformation.

That is, even if the holder 500 is twisted or deformed due to the mechanical property of the synthetic resin, the height of the space of the fixing groove 310 is larger than the thickness of the fixing protrusion 520, So that it is possible to prevent the drawing rail 300 from being deformed so as to cause a breakdown or malfunction of the drawer.

Here, the drawing rail 300 can be manufactured by bending a metal plate using a roll forming molding method or by extruding it into an aluminum profile.

At least one sliding carriage 400 is disposed and mounted between the guide rail 200 and the output rail 300 to minimize friction and noise by rolling motion, thereby inducing a smooth and smooth sliding movement of the output rail 300.
