PURPOSE:To do accurate installation work by forming integrally a horizontal and vertical relative positioning section between a suspending section which hangs from a removable horizontal mount section and a ceiling contact section which is placed along an indoor side of a ceiling board on the bottom of a device main body. CONSTITUTION:There are integrally formed a suspending section 3 which forms a positioning section 5 and a ceiling contact section 4 which is placed along an inner side 12a of a ceiling board 12 on horizontal mount section 2 to be mounted on the bottom 10a of a device main body 10. An inclined guide taper section 3a is formed n the suspending section 3. The span between the end face of the ceiling board 12 and the side of the device main body 10 and the vertical span H between the bottom of the device main body 10 and the indoor side 12 a of the ceiling 12 are set in such a fashion that it may conform to a predetermined length. It is, therefore, possible to carry out a relative positioning work for the device main body 10 and the ceiling board with accuracy and ease and prevent installation work-related troubles and maintain a fine outside view. |
