Moving mechanism of movable body

A moving mechanism of a movable body assembled for rotatably moving between a reference position and a deployed position on a support body by way of a supported part, comprising:

• a first stationary-side gear part and a second stationary-side gear part, arranged on a side of the support body;
• a movable-side gear part and a pinion gear, arranged on the supported part of the movable body;
• and
• a guide device for positioning the movable-side gear part to engage the first stationary-side gear part and the pinion gear to engage the second stationary-side gear part;
• wherein the first stationary-side gear part is formed along an arc of a virtual circle, and has teeth oriented toward a center side of the virtual circle;
• and
• the second stationary-side gear part is disposed adjacent to the first stationary-side gear part on the center side of said virtual circle, is formed along an arc of a separate virtual circle from the virtual circle, and has teeth oriented toward a center side of the separate virtual circle.
