Abstract
Provided is a shoulder joint structure for a figure, which makes a shoulder joint of a figure look human-like as much as possible when a corresponding arm of the figure is moved. The shoulder joint structure for a figure includes: a shoulder base part configured to form a base of a shoulder and an underarm of a figure; and an upper arm part to be coupled to the shoulder base part without a gap. The shoulder base part is pivotable about a first pivot axis relative to a body of the figure, the first pivot axis extending sideways and diagonally upward from the figure. The upper arm part is pivotable up and down about a second pivot axis relative to the shoulder base part, the second pivot axis extending in a front-and-rear direction of the figure when the figure has a corresponding arm down.
