<p>PROBLEM TO BE SOLVED: To provide an electric connection box that prevents a cover body from being finally fixed to a box body by mistake in the middle of assembling.SOLUTION: An electric connection box 100 includes a box body 10 mounted with an electronic circuit board 150 and a cover body 20 covering the box body 10. The cover body 20 includes: an upper wall 22; side walls 24A-24D extending from a peripheral edge of the upper wall 22; and claw portions 26 formed on the side walls 24A, 24C. The box body 10 includes: a base portion 12; inner walls 16A-16D extending upward from the base portion 12; outer walls 14A-14D located outside the inner walls 16A-16D and extending upward from the base portion 12; and engagement holes 19 formed on the outer walls 14A, 14C. Between the outer walls 14A-14D and the inner walls 16A-16D, a guide groove 18 for guiding the side walls 24A-24D of the cover body 20 is formed. The inner walls 16A-16D support the electronic circuit board 150 so that a peripheral edge 150A of the electronic circuit board 150 can abut on inner surfaces 27 of the side walls 24A-24D at a position above the claw portions 26 of the cover body 20.</p> |
