れている。 In the figure, 1 is an upper case, 2 is a lower case, and both cases 1 and 2 are made by integrally molding a hard resin material. The upper case 1 is provided with a latch arm 3 protruding toward the lower case 2 side, and a claw 3a is formed at the protruding tip of the latch arm 3. A step portion 4 is formed to protrude from the side wall surface 2a of the lower case 2. Reference numeral 4a indicates a guide wall to the hanging step 4, and a cover 5 is disposed on the outside of the hanging step 4 in parallel to the side wall surface 2a and extending from the hanging step 4. ing.
そして、掛止腕３は、上ケース１の作成時に一
体成形により形成され、掛止段部４及びカバー５

れる。 The latching arm 3 is formed by integral molding when the upper case 1 is created, and the latching step 4 and the cover 5 are integrally formed.
is formed by integral molding when the lower case 2 is created.
更に、掛止腕３は、弾性変形可能で且つ復元性
能を有し、上記掛止腕３の弾性力は、側壁面２ａ
に平行に働くように設定されている。 Furthermore, the locking arm 3 is elastically deformable and has restoring performance, and the elastic force of the locking arm 3 is
It is set to work in parallel to.
