An electrical-wire support structure (30) is disposed at a rotary connection portion of a device and connects first and second portions (11, 12) of the device. The second portion being rotatable about at least two rotational axes. The electrical-wire support structure includes frame members having a through-hole (36, 43) through which an electrical wire (51) may pass, and the through-hole (36, 43) is positioned on one of the rotational axes. An electrical wire (51) has first and second opposite ends. The first end is configured to be disposed on the first portion (11) and the second end is configured to be disposed on the second portion (12). The electrical wire is supported by such electrical-wire support structure such that the wire passes through the through-hole and at least one first bent portion (53) of approximately 180 degrees is formed on the electrical wire (51), and at least one second bent portion (54) of approximately 90 degrees is formed on the electrical wire (51) between the first bent portion (53) and each of the first and second opposite ends of the electrical wire (51).
