PROBLEM TO BE SOLVED: To enable the use of a conductor bar of different cross-sectional area depending on a current capacity and also enhance the heat radiating efficiency by enlarging the surface area when a current capacity is large. SOLUTION: A bar supporting member 100 can be mounted on a placing piece 104 by selecting wide width conductor bar 110b. 110c and narrow width conductor bar. A locking portion 105 is projected at the intermediate part in the width wise direction of the placing piece 104, an erecting wall 106 is provided at one end portion in the width wise direction of the placing piece 104, and an isolating wall 101a is formed at the other end in the width wise direction of the placing piece 104. The isolation wall 101a, locking portion 105 and erecting wall 106 are provided, respectively, against the placing piece 104, with the conductor bar 110b, hooking pawls 101b, 105a, 106a for holding the end of the conductor bars 110b, 110c. The wide width conductor bars 110b, 110c are mounted using the isolation wall 101a and erecting wall 106. The narrow width conductor bar is mounted using the isolation wall 101a and locking portion 105. |
