ABSTRACT:
A reciprocating-motion converting mechanism includes a cam that rotates around a rotation center; a reciprocating member that is reciprocated due to rotation of the cam; and a pressing unit that presses the reciprocating member to the cam. A first load torque is generated by a load applied at a point of contact of the cam and the reciprocating motion member. A load applying unit applies a load to the cam to generate a second load torque having a phase substantially opposite to a phase of the first load torque.
