Claims9
A vibration motor provided with a thin blocking body of a commutator's breakaway, the motor comprising:
- a housing;
- a rotating shaft being rotatably combined with the housing and having a recess formed on an outer periphery thereof;
- a commutator being fixedly combined with the shaft;
- and
- a blocking body being forcibly inserted into the recess and fixedly combined with the commutator, the blocking body having small thickness,
- wherein the commutator has a convex protrusion formed on an inner periphery surface thereof and the blocking body has a concave recess corresponding to the protrusion formed on an outer periphery surface thereof, the commutator and the blocking body being combined with each other so as to the protrusion and the recess be closely contact.
