PURPOSE: A remover for a weld bead and a decelerator for a grinder are provided to improve a cutting force by increasing torque of a motor and to save a cost by setting the motor in a small amount. CONSTITUTION: A remover for a weld bead and a decelerator for a grinder comprise a power generator, a gear box(20), a box cover(30), a motive gear(40), a direction conversion shaft(50), an idle gear(60), a deceleration shaft(70), and a spiral gear(80). The idle gear is engaged with the motive gear while inserting to the outside of the direction conversion shaft. The deceleration shaft is rotatably installed to penetrate through the box cover and is engaged with a driven gear(72) protruded to the front end and a middle gear(52). The spiral gear is integrally inserted to the outside of the deceleration shaft and is inserted inside of a main body. |
