PURPOSE:To seal the whole circumference between a lower case, from which each terminal of an apparatus body projects, and an upper case to the high degree of sealing at one operation by using a solid thermally fusing pellet. CONSTITUTION:The terminals 21 project to both sides of the proper 20, and the body is covered with the cases 22, 23. When the case 22 is fitted, the projecting sections 25 of the terminals are supported by the upper fringe 24 of the case. When the case 23 is set up, the frame type thermally fusing pellet 26 is fitted on the outer circumference of the body 20, and placed on the projecting sections 25 of each terminal. The pellet 26 is a brittle substance manufactured by hardening epoxy resin powder, and can easily be mounted because a reinforcing sheet 27 made of glass fiber is fast stuck on its inner circumferential surface. When the pellet 26 is heated and fused, it intrudes and fills in clearances among the projecting sections 25 of the terminals and the upper edge 24 of the case 22, and the whole circumference between the upper and lower cases can be sealed at high density by one operation. |
