Abstract
A rotary type linear reciprocating motion device includes: a driving part rotatably driven by a motor; a rotating part installed at one surface of the driving part, the rotating part transferring a rotational force of the driving part to an applicator; and a reciprocating part installed at the other surface of the driving part, the reciprocating part converting the rotational force of the driving part into a linear reciprocating motion force, the reciprocating part transferring the linear reciprocating motion force to the applicator. The driving part includes: a driving plate having both surfaces at which the rotating part and the reciprocating part are respectively installed; and a driving belt installed at an edge of the driving plate, the driving belt being in contact with a motor shaft of the motor to allow a driving force of the motor to be transferred to the driving plate by a frictional force.
