PURPOSE: To provide appearance of entrance pole with identity by a method wherein a stay and a functional pole are moldable by using a single mold material.

CONSTITUTION: A functional pole 4 is connected to the upper part of a hollow stay 2 through an elbow 3, and an apparatus 11 for a gate device is mounted on the functional pole 4. Since the stay 2 and the functional pole 4 can be molded by using a single mold, a man power required for manufacture of the entrance pole 1 and a cost are eliminated. As noted above, the stay 2 and the functional pole 4, having the same outside diameter as each other, are interconnected in an arm-form manner through an elbow 3, and by providing appearance of the entrance pole 1 with identity, excellent design properties suitable for a gate device are provided.
