<p>PURPOSE:To make proper closing and holding of a lid with respect to a housing case body, reduce cost of a case molding metal die and improve reliability of a housing case. CONSTITUTION:Side walls 11 and 21 of a housing case body 1 and a lid 2 are formed of side walls 11 and 21 which come across and engage with each other when the lid 2 is closed, and the side walls 11 and 21 are provided with a lock engaging part 5 which engages with the case body 1 and the lid 2 by locking. By this, a case including a lid functions to lock, a molding metal die need not have a slide core, and a case having a lock engaging part 5 can be produced easily and at a low cost. Further curving of a case can be prohibited so that the lid 2 does not cut into the case body 1, and further owing and closing of the lid 2 with respect to the case body 1 can be done safely and smoothly.</p> |
