A yarn feeder includes a switching mechanism which presets a swing direction of the yarn feeding port after completion of a yarn feeding operation, and, after having completed a yarn feeding operation, changes over the swing of the yarn feeding port from one yarn feeding position to another standby position interlocking with the released selective operation of an entraining device, in which the switching mechanism includes a feeder rod having a yarn feeding port at its lower end, which is composed of at least two members, both of the members being arranged to relatively slide each other in a vertical direction and provided with a push-up member to force upward respectively. The switching mechanism includes a support member for bearing the yarn feeding rod being provided with a regulation unit for regulating the upward movement of the yarn feeding port in the determined standby position, wherein the rise of the yarn feeding port in the standby position is limited below the determined altitude by using the regulation unit.
