In a battery accommodating device, a lock member 11 is disposed on a lid 5 which is pivotally supported by a case 1 and a protrusion 22 formed on an arm piece 28 of the lock member 11 is to be engaged with an engaging portion 27 of the case 1, and a second protrusion 23 is disposed on the arm piece 28. When a shock is applied to the device or the device drops, the engagement between the protrusion 22 and the engaging portion 27 may be canceled and the lid 5 may be opened. Even in this situation, the protrusion 23 is engaged with the engaging portion 27, and hence the lid 5 rests in a state where the lid is opened by a certain angle.
