Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 カバーを本体にガタを有せず容易に組付ける ことができ、且つカバーの取外し作業を容易に行うこと ができる組付部品のロック構造の提供。 【解決手段】 カバー１３の側端に可撓性の係止枠１５ を設け、本体７の側壁部５に係止枠１５の下端内縁１９ ａが係止される係止突起２３を突設し、カバー１３の上 板部１１によって本体７の開口部９を閉止した閉止状態 で係止枠１５が係止突起２３に係止される構造におい て、係止突起２３の上方で本体７の側壁部５の上端部 に、閉止状態で係止枠１５の下方への変位を許容する間 隙３０を設け、係止突起２３の下方で本体７の側壁部５ に、下方へ変位した係止枠１５の下端１９を側壁部５か ら離間させる解除突起３７を設け、係止枠１５は、係止 突起２３と係止した組付状態で下方へ変位し、組付状態 からさらに下方へ変位させた状態で解除突起３７によっ て下端１９が側壁部５から離間するように設けた。 (57) Abstract: [PROBLEMS] To provide a lock structure for an assembly part that allows a cover to be easily assembled to the main body without backlash and allows the cover to be easily removed. SOLUTION: A flexible locking frame 15 is provided at a side end of a cover 13. And the lower end inner edge 19 of the locking frame 15 is provided on the side wall portion 5 of the main body 7. A structure in which a locking projection 23 for locking a is projected, and the locking frame 15 is locked to the locking projection 23 in a closed state in which the upper plate portion 11 of the cover 13 closes the opening 9 of the main body 7. At the upper end of the side wall portion 5 of the main body 7 above the locking projection 23, a gap 30 that allows the downward movement of the locking frame 15 in the closed state is provided. Side wall 5 Is provided with a release projection 37 for separating the lower end 19 of the locking frame 15 displaced downward from the side wall portion 5, and the locking frame 15 is displaced downward in an assembled state in which the locking frame 23 is locked, The lower end 19 is provided so as to be separated from the side wall portion 5 by the release projection 37 in a state where the lower end is displaced further downward from the attached state.
