Abstract
An auto-returning drawer rail is implemented in furniture having a drawer cavity and a drawer, and the auto-returning drawer rail has a drawer rail assembly, an auto-returning device and a buffering device. The drawer rail assembly is mounted in the drawer cavity and has a rail bracket, an outer track and an inner track. The auto-returning device is mounted in the drawer rail assembly and has a base, a sliding block, a connector and two springs. The base is mounted on the rail bracket. The sliding block is mounted slidably on the base. The connector is connected securely to the sliding block between the rail bracket and the base and has two clasping tabs engaging the base. The buffering device is mounted in the auto-returning device to prevent the drawer from returning too fast and has a damper and a drive shaft being connected to the connector.
