MOVABLE PART STRUCTURE OF ROBOT

摘要

PROBLEM TO BE SOLVED: To prevent bad effect of oil and fat including grease necessary for mechanical structure parts on electric structure parts and lead wires, in a movable part structure of a robot that is electrically controlled. SOLUTION: A gear array 71 and a wiring board 61 are stored in a casing body 30 as a movable part attached to a torso module 10 via a shaft body 20 in a cylinder shape. The shaft body is formed as a hollow cylinder and the internal space of the casing body 30 connected to the shaft body 20 is separated into a machine room 33 and electricity room 34 in an in-and-out direction by a partition wall 32. The gear array 71 is stored in the machine room 33 and the wiring board 61 is stored in the electricity room 34. A lead wire inserted through the shaft body 20 is connected to the wiring board 61. The shaft body 20 is reciprocatingly swung by a driving mechanism provided to the torso.
