PROBLEM TO BE SOLVED: To provide a toy robot which can make boxing actions with both right and left arms made to act alternately using a positive motion cam with a new structure. SOLUTION: When the rotary body of the positive motion cam 340 of this toy robot is rotated in one direction, force is applied only to a first connecting shaft 410, and when rotated in the other direction, force is applied only to a second connecting shaft. When a drive motor 325 is driven to rotate the rotary body of the positive motion am 340 in one direction, force is applied only to a first connecting member 403 by way of the first connecting shaft, and a left arm attaching shaft 401 is rotated to move the left arm. When the drive motor is driven to rotate the rotary body of the positive motion cam in the other direction, force is applied only to a second connecting member 324 by way of the second connecting shaft. However, since a support rod 306 is fixed, the trunk 301 is revolved around the support rod. By the revolution of the trunk, a right arm attaching shaft 391 is rotated to move the right arm.
