Abstract

PURPOSE:To ensure smooth sliding of a mounting device prior to mounting on a ceiling by protrudingly providing an elastic action piece portions that come in pressure contact with the external surface of the apparatus body in addition to portions which engage with and lock in grooves in the body and a portion which come in contact with the ceiling, a mounting device which locks the apparatus body on the ceiling. CONSTITUTION:With the apparatus body 1 mounted in position, the pressing piece portion 11 of the mounting device body 5 catches the engaging groove 3 of the body 1 in a wedge-like manner to hold the body 1 positively on a ceiling surface 13. However, prior to mounting by protrudingly providing an elastic action piece portion 12 on the base portion 6 of the body 5 to make pressure contact with the external surface of the body 1, the body 5 can be readily moved along grooves 3 because a pressing piece portion 11 does not catch the grooves 3 for locking. Also, when the body 1 is inserted in a mounting hole 23 in the ceiling surface, the body 5 is positively held in a specified position in the groove 3. After insertion, the body 1 can be held on the ceiling surface 13 merely by lowering the body 5 along the grooves 3, thus ensuring easy mounting work.
