A door opener includes a driving device having a first transmission member driven by a motor. A push rod is connected to the first transmission member to move therewith. A pressing rod unit is pivotably coupled to the push rod and includes a coupling sleeve, first and second end pieces coupled to the coupling sleeve, and an adjusting screw rod in threading connection with the second end piece. The first end piece is coupled with a first pivotal member coupled with a door. An end of the adjusting screw rod is located outside of the coupling sleeve and is coupled with a second pivotal member pivotably connected to the push rod. When the adjusting screw rod rotates, the adjusting screw rod moves in an axial direction of the coupling sleeve to change a length of a portion of the adjusting screw rod outside of the coupling sleeve.
