Sewing machine

A sewing machine that moves, relative to a cloth, a needle attached to a needle bar up and down based on drive force from a rotating upper shaft to forma stitch, the sewing machine comprising:

• a needle-bar swing unit swinging the needle bar in an orthogonal direction to a cloth feeding direction;
• a first output generating unit reciprocating a first output point along an output axis that swings in accordance with a swing operation of the needle by the needle-bar swing unit;
• a link unit linking the first output point with the needle bar;
• and
• an output axis moving unit moving the output axis in the cloth feeding direction in accordance with an operation of the needle-bar swing unit,
• wherein the link unit changes an inclination in accordance with the movement of the output axis, and moves up and down the needle bar in substantially parallel with the output axis while maintaining the inclination.
