Abstract:
1. A moving mechanism comprising: a support; a moving body which moves in a predetermined moving direction with respect to the support; a pair of first grooves which are provided on the support and formed parallel to the moving direction; a pair of second grooves which are provided on the moving body and face the first grooves; a plurality of rolling bodies which are provided between the first grooves and the second grooves, and roll in accordance with movement of the moving body; two rows of moving shafts which include the rolling bodies rolling between the first grooves and the second grooves, and are parallel to the moving direction, the two rows of the moving shafts are separated from each other in a direction intersecting a direction in which the support and the moving body face each other; and a vibrating body which includes a piezoelectric material generating vibration and is supported by one of the support and the moving body while being biased toward the other one of the support and the moving body, wherein a direction in which the first grooves and the second grooves face each other intersects the direction in which the support and the moving body face each other, and the positional relationship between the first grooves and the second grooves is reversed between the two rows of moving shafts, and a biasing direction in which the vibrating body is biased is inclined with respect to a moving surface including the two rows of moving shafts.
