<p>PURPOSE: To prevent flooding into a case from a die releasing hole without requiring a lower cover by placing in contact the die releasing hole opened at the bottom wall of the lower case in the fixed state with the lower surface of a recessed area of the external wall of the upper case constinued to a second water-proof frame wall surrounded by the first water-proof frame wall and surrounding at its frame wall the first water-proof frame wall. CONSTITUTION: After a bus bar 3 and an insulated late 4 are housed in the required area in a lower case 10, an upper case 11 is fitted into the lower case 10 and these are locked through engagement of lock pawl 13 and the pawl 17 to be locked. Under this engagement condition, the second water-proof frame wall 18 surrounds the internal side surface of the case of the first water-proof frame wall 15 and the upper surface 15a of the internal surface of case of the first water-proof frame wall 15 is placed in contact with the lower surface 11c of the recessed area 11b of the upper case 11. Thereby, flooding by water from the die releasing hole 14 into the bus bar housing section surrounded by the external wall 11a of the upper case 11 and the second water-proof frame wall 18 can be reliably prevented.</p> |
