The protrusion 141 protrudes from the through hole 124 The projection fixing portion 142 is engaged with the end of the fixing protrusion 141 to fix the lower housing 11 and the cover 12 in close contact with each other. For example, a cap nut may be used as the protrusion fixing part 142, and a screw thread may be formed at the end of the fixing protrusion 141, so that the protrusion fixing part 142 and the fixing protrusion 141 can be screwed together.

The connection pin 133 of the cover 12 is located on the upper side of the lower housing 11 so that the swinging shaft of the cover 12 is positioned above the lower housing 11, The interference between the inner wall of the through hole 125 and the fixing protrusion 141 can be reduced at the time of the rotation of the cover 12 when the cover body 12 is opened, It is possible to reduce the diameter h1 of the through-hole 125 and to facilitate the formation of the through-hole 125.

The horizontal member 213a and the vertical member 213b are formed so as to have a wider width h3 as they are connected to each other so that the horizontal member 213a and the vertical member 213b have strong strength, Since the lateral member 213a and the vertical member 213b are welded in a lattice form to form the outer mesh net 213, a large number of holes can be formed in the outer mesh net 213 than a hole is formed in the metal plate It is possible to increase the strength while maximizing the porosity and minimize the welding area, thereby facilitating the manufacturing. When the outer mesh network is made by perforating a hole in the metal plate, the width of the flesh enclosing the hole needs to be increased in order to maintain the strength of the outer mesh network, so that the porosity is lowered when the outer mesh network is made.
