摘要： There is disclosed a needle threader comprizing a support provided with a needle accommodating notch and a thread guide groove, and a pair of resilient rollers rotatably mounted on the support and contacting at the respective peripheral edges with each other. In the needle threader, an eye of a needle accommodated in the needle accommodating notch is located on a tangent line passing through the contact portion of the pair of resilient rollers. A thread introduced via the thread guide groove towards the proximity of the contact portion of the pair of resilient rollers is gripped by and transferred through rotation of the resilient rollers, resulting in the thread being passed through the eye of the needle.
