Japanese Patent JP3607400

B2

A motor device having a hollow casing in which a mechanism for converting continuous rotational motion of a rotating member which is rotated by a motor into reciprocating oscillatory motion and reversibly rotates the output shaft in the forward rotational direction and in the reverse rotation direction. This motor device includes a gear wheel fixed to the output shaft. Furthermore, it includes a driving force conversion member comprising a meshing portion which is meshed with the gear wheel, which converts continuous rotational motion of the rotating member into oscillatory motion around the output shaft as a center for oscillation, and which reversibly rotates the gear wheel in the forward rotational direction and in the reverse rotational direction. It further includes a pair of holding members which support the meshing state of the gear wheel and the meshing portion of the driving force conversion member in the thickness direction, and which oscillate around the output shaft as a center for oscillation. This driving force conversion member includes a fixed shaft which supports and enables the pair of holding members to oscillate and which lies upon an oscillation path around the output shaft as a center for oscillation. And a one of the pair of holding members which confronts an inner wall of the hollow casing comprises a contacting portion which slides on the inner wall of the hallow casing.
