Zusammenfassung:	To make a minimum turning radius of a robot small. A robot includes a first arm portion, a second arm portion, an intermediate link portion, a first link portion and a second link portion. The first link portion forms a first parallel link mechanism among the first arm portion, the intermediate link portion and a fixed base portion. The second link portion forms a second parallel mechanism among the second arm portion, the intermediate link portion and a movable base portion. A distance from a connection shaft of the second link portion with the intermediate link portion to a connection shaft of the first arm portion with the second arm portion is shorter than a distance from a connection shaft of the second link portion with the intermediate link portion to a connection shaft of the first arm portion with the second arm portion.
