A flat knitting machine comprising: fixed sinkers that are arranged side by side at a front end portion of a needle bed, each of the fixed sinkers including a body including a fitting portion at a rear end thereof and a curved portion at a middle part thereof in a longitudinal direction, and a head protruding from a front end of the body toward a needle-bed gap, wherein a needle-bed-front-end support portion is formed in the front end portion of the needle bed, the needle-bed-front-end support portion supporting a sinker-front-end support portion of each of the bodies around an axis (m) of a wire, which extends in a direction in which the bodies are arranged side by side, and allowing the head to swing around the axis (m) of the wire in directions toward and away from a needle-bed gap center (Ga), and wherein a snap-fit recess is formed in a lower surface of the front end portion of the needle bed, the snap-fit recess allowing the fitting portion, which is at the rear end each of the bodies, to be snap fitted to a bottom surface and a front-end side surface of the snap-fit recess by using a spring force generated when the curved portion of the body is bent in a state in which the sinker-front-end support portion is supported by the needle-bed-front-end support portion, the flat knitting machine being characterized in that a linear-member support portion is formed in the front end portion of the needle bed, the linear-member support portion opening toward the bodies and supporting a linear member that is inserted in the direction in which the bodies are arranged side by side; and a contact portion of each of the bodies, which is located between the curved portion and a front end of the body and which contacts the linear member when the linear member is inserted into the linear-member support portion, is pressed toward the needle-bed gap center (Ga) to swing the head around the axis (m) of the wire in the direction away from the needle-bed gap center (Ga). fixed sinkers that are arranged side by side at a front end portion of a needle bed, each of the fixed sinkers including a body including a fitting portion at a rear end thereof and a curved portion at a middle part thereof in a longitudinal direction, and a head protruding from a front end of the body toward a needle-bed gap, a body including a fitting portion at a rear end thereof and a curved portion at a middle part thereof in a longitudinal direction, and a head protruding from a front end of the body toward a needle-bed gap, wherein a needle-bed-front-end support portion is formed in the front end portion of the needle bed, the needle-bed-front-end support portion supporting a sinker-front-end support portion of each of the bodies around an axis (m) of a wire, which extends in a direction in which the bodies are arranged side by side, and allowing the head to swing around the axis (m) of the wire in directions toward and away from a needle-bed gap center (Ga), and wherein a snap-fit recess is formed in a lower surface of the front end portion of the needle bed, the snap-fit recess allowing the fitting portion, which is at the rear end each of the bodies, to be snap fitted to a bottom surface and a front-end side surface of the snap-fit recess by using a spring force generated when the curved portion of the body is bent in a state in which the sinker-front-end support portion is supported by the needle-bed-front-end support portion, the flat knitting machine being characterized in that a linear-member support portion is formed in the front end portion of the needle bed, the linear-member support portion opening toward the bodies and supporting a linear member that is inserted in the direction in which the bodies are arranged side by side; and a contact portion of each of the bodies, which is located between the curved portion and a front end of the body and which contacts the linear member when the linear member is inserted into the linear-member support portion, is pressed toward the needle-bed gap center (Ga) to swing the head around the axis (m) of the wire in the direction away from the needle-bed gap center (Ga).
