At this time, the maximum diameter portion 34 of the boss portion 32 is set to be larger than the diameter of the opening 12, but the boss portion 32 is formed of an elastic material such as synthetic resin and elastically deformed so as to reduce the diameter. Therefore, when the operator inserts the boss portion 32 into the insertion hole 30 against the elasticity of the boss portion 32, the maximum diameter portion 34 of the boss portion 32 is pressed against the inner peripheral surface of the insertion hole 30 to reduce the diameter. Thus, the boss portion 32 can be inserted into the insertion hole 30.

  When the boss portion 32 has been inserted into the insertion hole 30, the boss portion 32 can be expanded in diameter, so that the pressing by the inner peripheral surface of the insertion hole 30 is released, and the maximum diameter portion 34 of the boss portion 32 is expanded, The annular locking surface 35 is engaged from the back surface of the door 2, and the edge portion 13 of the opening 12 of the door 2 is sandwiched between the annular locking surface 35 and the flange portion 11.

And the apparatus main body 4 is supported by the hook part 23 at the upper part so as not to move forward and backward, and the apparatus main body 4 is supported by the fitting part 24 at the lower part so as not to move forward and backward and is attached to the door in a state where it cannot be easily removed. .
Thus, the apparatus body 4 can be easily operated by a series of operations such as locking the hook portion 23 to the edge portion 13 of the opening 12 of the door 2 and subsequently inserting the fitting portion 24 into the insertion hole 30 of the door 2. Can be installed.

  Further, the fitting portion 24 is constituted by a columnar protrusion 31 integrally formed on the back surface of the flange portion 11 and a cylindrical boss portion 32 mounted so as to be fitted on the protrusion 31. Since the fitting portion 24 is simply fitted to the protrusion 31 by using the elasticity of the boss portion 32, it can be easily and reliably attached.

In the above embodiment, the hook portion 23 is provided on the upper portion of the device main body 4, the fitting portion 24 is provided on the lower portion of the device main body 4, and the device main body 4 is locked by the hook portion 23 on the upper portion when attached to the door 2.
