Claim Text:
1. A moving mechanism comprising: a support provided at a predetermined position and supporting the moving mechanism; a first moving body which is movable in a first direction with respect to the support; a first vibrating body which includes a piezoelectric material to generate vibration in the first direction and is supported by one of the support and the first moving body while being biased toward the other one of the support and the first moving body; a second moving body which is provided on a side of the support with the first moving body therebetween, is moved with the movement of the first moving body, and is movable in a second direction intersecting the first direction with respect to the first moving body; a second vibrating body which includes a piezoelectric material to generate vibration in the second direction and is supported by one of the first moving body and the second moving body while being biased toward the other one of the first moving body and the second moving body; a pair of first grooves which are provided in the support and formed parallel to the first direction; a pair of second grooves which are provided in the first 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 first moving body; and a moving shaft which includes the rolling bodies and is parallel to the first direction, wherein two rows of the moving shafts are spaced apart from each other in a direction intersecting a direction in which the support and the first moving body face each other, a direction in which the first grooves and the second grooves face each other intersects a direction in which the support and the first 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 first vibrating body is biased is inclined with respect to a moving surface including the two rows of moving shafts.
