PROBLEM TO BE SOLVED: To provide an electric circuit housing case capable of improving the efficiency of maintenance work. SOLUTION: A case position determining mechanism 30 includes a lock lever 35 supported rotatably on a pivot 353 disposed on a case side plate 3a and a guide plate 22 disposed on a case side face 2a. An opening 221 is formed at the guide plate 22 to extend deep inside the guide plate. A projection serving as a lock lever action portion 352 is formed at one end of the lock lever 35. The lock lever action portion 352 is engaged with the opening 221 to move forward and backward as an electric circuit mounting case 3 is inserted and pulled out. The opening 221 has recesses formed as a disengaging position setting portion 223 and a detection position setting portion 224. When the electric circuit mounting case 3 is pulled out, the lock lever action portion 352 is locked to these recesses. The other end of the lock lever 35 projects out of a slit hole 321 of a front panel 32, and the position of the other end in the slit hole 321 corresponds to the mounting position of the electric circuit mounting case 3.
