In a horizontally rotating looptaker for a sewing machine having a bobbin case mounted for relative rotation on a raceway within a rotating cup-shaped hook body a magnet is carried by the bobbin case adjacent the outer periphery thereof and a fixed member of magnetic material is disposed in close, non-contacting relation to said magnet to continuously bias said bobbin case into engagement with the raceway to prevent the occurrence of undesirable noise.
