Abstract

A shoulder joint structure of a doll body includes a first joint member housed inside a trunk of the doll body and connected to the trunk, a second joint member housed inside the trunk and connected to the first joint member, and a third joint member connected to the second joint member and an arm of the doll body through an opening formed in a shoulder of the trunk. The first joint member is rotatable about a first connecting portion between the trunk and the first joint member, so as to move the third joint member away from a trunk axis of the trunk in a shoulder width direction. The second joint member is rotatable about a second connecting portion between the first joint member and the second joint member, so as to move the third joint member away from the trunk axis in the shoulder width direction.

First claim

What is claimed is:

1. A shoulder joint structure of a doll body, comprising:
a first joint member housed inside a trunk of the doll body and connected to the trunk;
a second joint member housed inside the trunk and connected to the first joint member; and
