PURPOSE:To reduce number of components and to simplify the assembling, by aligning a steel crossarm through the use of a pin incorporatedly forming a flange at the upper side. CONSTITUTION:This side surface of a guide pin 21 contacts with a side ridge of a steel crossarm 10 freely slidably to align the arm 10 for left and right direction. Further, a flange 22 formed incorporatedly at the upper part of the guide pin 21 is engaged with the upper side of the arm 10 freely slidably to align the arm 10 for up and down direction. The left and right side ridge of the arm 10 is provided with a notch 23 which is an end play of the arm 10 in setting the arm 10 on a base plate 20. Thus, an E-ring which has been provided to the upper part of the pin is not necessary at all, allowing to reduce the number of components and to simplify the assembling. |
