Tilting device

A tilting device, comprising:

• an upper movable plate arranged on a side on which an object to be tilted is arranged;
• an intermediate movable plate arranged below the upper movable plate and connected to the upper movable plate in a rotatable manner via an upper rotation shaft;
• a first actuator arranged between the upper movable plate and the intermediate movable plate;
• a first lower movable plate arranged below the intermediate movable plate and connected to the intermediate movable plate in a rotatable manner via a first lower rotation shaft;
• a second actuator arranged between the intermediate movable plate and the first lower movable plate;
• a first connecting member that is connected to the upper movable plate in a rotatable manner via a first connecting rotation shaft at an end portion on a side of a first direction opposite to an end portion at which the upper movable plate is connected to the intermediate movable plate, and that is connected to the first lower movable plate in a rotatable manner via a second connecting rotation shaft at an end portion on a side of a second direction opposite to the first direction;
• a second lower movable plate arranged below the first lower movable plate and connected to the first lower movable plate in a rotatable manner via a second lower rotation shaft;
• a third actuator arranged between the first lower movable plate and the second lower movable plate;
• a third lower movable plate arranged below the second lower movable plate and connected to the second lower movable plate in a rotatable manner via a third lower rotation shaft;
• a fourth actuator arranged between the second lower movable plate and the third lower movable plate;
• and
• a second connecting member that is connected to the first lower movable plate in a rotatable manner via a third connecting rotation shaft at an end portion on one side of a direction orthogonal to the first direction in a plan view, and that is connected to the third lower movable plate in a rotatable manner via a fourth connecting rotation shaft at an end portion on the other side of the direction orthogonal to the first direction in the plan view.

• an intermediate movable plate arranged below the upper movable plate and connected to the upper movable plate in a rotatable manner via an upper rotation shaft;
• a first actuator arranged between the upper movable plate and the intermediate movable plate;
• a first lower movable plate arranged below the inteiiiiediate movable plate and connected to the intermediate movable plate in a rotatable manner via a first lower rotation shaft;
• a second actuator arranged between the intermediate movable plate and the first lower movable plate;
• and
• a first connecting member that is connected to the upper movable plate in a rotatable manner via a first connecting rotation shaft at an end portion on a side of a first direction opposite to an end portion at which the upper movable plate is connected to the intermediate movable plate, and that is connected to the first lower movable plate in a rotatable manner via a second connecting rotation shaft at an end portion on a side of a second direction opposite to the first direction, wherein the first actuator comprises a first expansion/contraction bag capable of expanding and contracting by supply and exhaustion of gas,
• the second actuator comprises a second expansion/contraction bag capable of expanding and contracting by supply and exhaustion of gas, and
• the tilting device further comprises a control unit that controls adjustment of a tilt angle of the upper movable plate by controlling supply/exhaustion of gas to/from the first expansion/contraction bag and the second expansion/contraction bag.
