PURPOSE:To position a three-way frame accurately without requiring a high skill by installing receiver members at the right side and the left side of an opening, extending a standard rod member laterally by providing it in a horizontal condition making an index means as the standard, and providing a tentative fixing means of the three-way frame to the stardard rod member. CONSTITUTION:On both vertical wall surfaces of an opening formed on the wall 2 of an elevator entrance, receiver members 11 are installed respectively at the positions almost symmetric each other, and a standard rod member 12 is extended laterally between the receiver members 11, by regulating its position to the longitudinal and the lateral directions, and providing it in a horizontal condition making an index means as the standard. And a tentative fixing means to fix a three-way frame 3 tentatively is provided to the standard rod member 12 making the index means as the standard, by regulating both vertical frames 3a of the three-way frame 3 in a specific position relation respectively. In such a way, the centering work and the positioning work of the three-way frame 3 is carried out simply, no positioning slippage of the three-way frame 3 is generated when it is fixed regularly to a wall side edge 2b, and furthermore, the left side and the right side vertical frames 3a of the three-way frame 3 can be positioned together.
