Claim:
A slide rail apparatus constituted of an upper rail and a lower rail being slidably coupled with each other, comprising: a first rail having a cross section of a substantially inversed U-like shape formed with a planar base portion and a pair of vertical walls formed at both sides thereof, and including a first pair of flange portions formed by bending the vertical walls outward, a second rail having a substantially U-shaped cross section formed with a planar base portion and a pair of vertical walls formed at both sides thereof, and including a second pair of flange portions formed by bending the vertical walls inward as well as a pair of right and left grooves between the vertical walls and the flange portions, both flange portions of the first rail are slidably fitted with both grooves of the second rail; by coupling the both the first and the second rails, a first substantially box-like cross section is formed with the respective base portions and vertical walls; and a locking mechanism having a locking member for locking with and unlocking from a locking portion provided on the first pair of flanges and a plurality of locking teeth provided on the second pair of flanges is disposed inside the first box-like cross section, and the locking member includes a mounting portion having a substantially U-shaped cross section and is disposed inside the substantially inversed U-like shape of the first rail; and a second substantially box-like cross section is formed by coupling the locking member with the second rail.
