The present invention relates to a ball screw for a deflector-type brake module in an electric brake of a small electric vehicle, which comprises: a deflector (110) which includes a head unit (111) which includes nuts and screws, has a circular or oval cross-sectional structure, and is inserted into and engaged with a hanging bump formed by being indented in a nut, an insertion unit (112) in a shape of a pillar protruding from a lower surface of the head unit (111) to be inserted into and engaged with a penetrating hole which is formed by penetrating an outer surface of the nut, and a fixing unit (113) placed on an outer surface of the insertion unit (112) in a sawtooth shape; and an attachment/detachment means (120) which includes a head unit (121) in a circular cross-sectional structure to be inserted into and engaged with an upper surface of an upper hanging bump formed by being indented in a nut, an engagement rod (122) in a structure protruding from a lower surface of the head unit (121) in a cylindrical shape to be inserted into and engaged with an engagement hole formed by penetrating an outer surface of the nut, a handle (123) in a semicircular ring shape to be engaged with a ring formed on the upper surface of the head unit (121) to be rotatable, a support bump (125) in a shape of a ring protruding from an outer surface of the engagement rod (122) as one body to be placed on the upper surface of a lower hanging bump in a space between the upper hanging bump and the lower hanging bump, and a spring (124) placed between a lower surface of the upper hanging bump and the support bump (125) to have an elastic force to press the engagement rod (122) in the direction of the penetrating hole. The present invention aims to provide the ball screw for the deflector-type brake module in the electric brake of the small electric vehicle, which is able to secure precision and to minimize noise.
