PURPOSE: A wiper arm protecting a blade is provided to minimize deformation or damage of a blade contacted to a wind glass caused by polluted material or heat through a wiper arm. CONSTITUTION: A wiper arm for protecting a blade comprises a blade(2) contacted to a wind glass; a spring(3) mounted between an arm head(1) and the blade; a retainer(4) having the spring; a wiper arm is connected trough a hinge shaft(5); and a fixing pin inserted to a hole to support the retainer. The fixing pin supports the retainer while rotating the retainer around on the hinge shaft of the arm head. The retainer is rotated by inserting the fixing pin into the hole of the arm head while contacting the blade to the wind glass. The blade is contacted to the wind glass by removing the fixing pin from the hole. The hole is arranged on the retainer and the arm head. Thereby, the wiper arm for protecting the blade prevents damage of deformation of the blade caused by polluted material. Moreover, the wiper arm for protecting the blade prevents the blade from attaching to the wind glass.
