Slide rail assembly with buffer mechanism

A slide rail assembly with buffer mechanism, comprising:

• a first rail;
• a second rail movable relative to said first rail, said second rail comprising a first working feature located at one end thereof;
• and
• a buffer device located on one side of said first rail, said buffer device comprising a slider and a movable device, said slider is movably positioned on one side of the first rail, said slider comprising a second working feature and a third working feature respectively located at two opposite ends thereof and a first elongated slot opened between said second working feature and said third working feature, said movable device is located in the first elongated slot;
• wherein when said second rail extends out and displaces to a first distance, said first working feature abuts against said second working feature of said slider, causing said second working feature to displace and to drive said slider, so that said movable device generates a resistance;
• when said second rail retracts and displaces to a second distance, said first working feature abuts against said third working feature of said slider and causes said third working feature to displace and to move said slider, so that said movable device generates a resistance.
