ABSTRACT:
A drawer rail having an auto-returning device has an outer track, an inner track, a driving block formed on the outer/inner track and a base mounted on the opposite inner/outer track. The base has a spring recess and a block recess with a positioning cutout to respectively receive a spring and a sliding block. The sliding block is pulled by the spring. An elongated through hole is defined in the block recess to allow parts of the sliding block to penetrate to engage with the driving block. When the outer/inner track moves away, the sliding block is pushed by the driving block to bias at the positioning cutout to allow the driving block to release from the sliding block. When the outer/inner track moves near, the driving block urges the sliding block back to a horizontal place and the spring pulls the sliding block back to an original position automatically.
