[Problems to be solved by the device]

 In the above-mentioned conventional example, when the battery is inserted into the dry battery storage portion of the electric device, the battery is pushed back due to the pressure of the energizing blade, making it difficult to attach the lid. Also, depending on the pressure of the biasing spring, the battery may pop out, hindering battery replacement.

[0006]

[Means for Solving the Problems]

 The present invention has been made for the purpose of solving the above-mentioned problems, and it is an object of the present invention to reduce the force of an urging spring that pushes back a dry battery in the longitudinal direction in a battery housing portion by means other than a lid. For this reason, a protrusion for fixing the dry battery is provided near the battery insertion port.

[0007]

[Action]

 According to the embodiment of the present invention, according to the above configuration, the battery end of the electric device is provided with a protrusion near the battery insertion port, so that the battery end is a bias spring for the protrusion. As a result, the battery is prevented from popping out and the battery lid is easily attached.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments of the present invention shown in the drawings. Needless to say, the present invention is not limited to these embodiments.

FIG. 1 is a perspective view of a dry battery case body 1 and a lid 6 according to an embodiment of the present invention. The case body 1 includes a battery housing 2 therein. The battery compartment 2 is provided with, for example, three battery stoppers 3 of the present invention on the bottom surface thereof. In FIG. 1, a lid 6 having a locking piece 5 that locks with the locking portion 4 of the battery storage portion 2 is further provided as the lid of the battery storage portion 2. The lid 6 is a negative contact that contacts the negative side (plus side) of the battery when the positive side (minus side) of the battery contacts a coil spring contact (described later) provided inside the battery housing part 2. For example, three (plus contact points) 7 are provided. When the lid 6 is covered with the main body 1, the contact 8 on the main body side and the contact 9 on the lid side are connected to form a battery circuit.

FIG. 2 is a cross-sectional view of the dry battery case 1 and the lid 6. In the present invention, for example, three batteries can be stored, but in FIG. 2, the cross section of the main body and the lid for one battery is shown. It is shown in the figure. The dry battery case 1 of the present invention is provided with a coil spring contact 10 therein, and a positive side (negative side) contact of the battery comes into contact therewith. The locking piece 5 of the lid 6 is locked to the locking portion 4 of the main body 1, but immediately after the locking piece 5 of the lid 6 is locked to the locking portion 4 of the main body 1, The upper locking piece 5 ′ is locked to the upper locking portion 4 ′ of the main body 1 so that the lid 6 is fixed to the main body 1. The vicinity 11 of the upper locking piece 5'of the lid 6 is elastically extended from the main body of the lid 6 and serves as a lock mechanism for the battery lid.

In FIG. 2, a, that is, the height of the battery stopper is set so that b in the figure, that is, the dimension of the battery insertion opening is slightly larger than the outer diameter of the battery used.

FIG. 3 is a cross-sectional view of the dry battery 12 being inserted into the dry battery case having the battery stopper.
