Abstract

PURPOSE:To improve the watertightness of a joined part, and to prevent the infiltration of water into the inside by providing a diaphragm mechanism for absorbing a fluctuation of pressure in a case, when pressure of air in the case is fluctuated with a temperature variation. CONSTITUTION:In about a center part of a cover part 8 in a case 2 of the remote controller, an opening part 30 is provided, and on the end face of a wall 30a for surrounding it, a diaphragm 31 is joined and provided through a sealing agent. From the outside of the opening part 30, a cover 32 is fitted in by forming a prescribed space 33 between its cover and the diaphragm 31. Also, an air hole 34 is formed in the cover 32. As for the diaphragm 31, in the case the remote controller 1 is floated on the bathroom, air in the case expands, and on the other hand, in the case the bathroom is cooled after it is used and air contracts and pressure is fluctuated, it is deformed elastically and absorbs a fluctuation of pressure. In such a way, pressure of air in the case is kept constant irrespective of a temperature variation.
