PROBLEM TO BE SOLVED: To provide a structure of fixing an object to be fixed on a wall material reducing a working space in a wall material back surface and facilitating the fixing of an object to be fixed at a desired position and providing stable and sufficient fixing strength.
SOLUTION: This structure is a fixing structure of fixing an object to be fixed on a front surface side of a hole formed on a wall material through a fixture. The fixture is provided with a shaft having a function of fixing the object to be fixed on the tip part, plural wall back contact plates rotatably inserted in a base side part of the shaft, a hole fitting member formed in a shape generally corresponding to a hole on the wall material and of which shaft hole a shaft is inserted through. Plural wall back contact plate are inserted through the hole on the wall material from the front surface side in a generally layered condition and are rotate. The tip part, thereby, is spread and contacted on the back surface of the wall material, and the shaft is projected out from the shaft hole of the hole fitting member fitted in the hole to the front surface side of the wall material, and the object to be fixed is fixed on the projection part of the shaft. The wall back contact plates, for example formed with four plates and in spread condition, exhibit generally cross shape and contact the back surface of the wall material.
