Moving mechanism, robot hand, electronic component transport device, electronic component inspection device, liquid feed pump, printing device, projection device, and transport device

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,
• the vibrating body is biased toward one of the support and the moving body at a position separated from a moving surface including the two rows of moving shafts, and
• a biasing direction in which the vibrating body is biased is parallel to the moving surface and intersects the moving direction.

A moving mechanism comprising:

• a support which supports a movable mechanism;
• a moving body which is arranged movably in a predetermined moving direction with respect to the support;
• a first groove which is provided in the support and formed parallel to the moving direction;
• a second groove which is provided in the moving body, is formed parallel to the moving direction, and is formed at a position facing the first groove;
• and
• a vibrating body which is arranged in the support and biased to press the moving body or is arranged in the moving body and biased to press the support,
• wherein a direction in which the first groove and the second groove face each other intersects a direction in which the support and the moving body face each other, and
• a biasing direction in which the vibrating body is biased intersects the direction in which the first groove and the second groove face each other and the direction in which the support and the moving body face each other.

A moving mechanism comprising:

• a moving body which is arranged movably in a predetermined moving direction with respect to the support;
• a first groove which is provided in the support and formed parallel to the moving direction;
• a second groove which is provided in the moving body, is formed parallel to the moving direction, and is formed at a position facing the first groove;
• and
• a vibrating body which is arranged in the support and biased to press the moving body or is arranged in the moving body and biased to press the support,
• wherein a biasing direction in which the vibrating body is biased is parallel to a plane including a direction in which the first groove and the second groove face each other and a direction in which the support and the moving body face each other, and
• a portion of the vibrating body which presses the support or the moving body is separated from the plane.
