Batteries such as nickel-cadmium batteries and lead-acid batteries are used in this type of equipment, and when these batteries are charged, water in the batteries is electrolyzed to produce hydrogen gas and oxygen gas. These hydrogen gas and oxygen gas generated by normal charging are recombined inside the battery and converted into water. However, if the amount of both gases generated exceeds the ability to recombine and increases the internal pressure of the battery, both gases will be released to the outside of the battery through a safety valve provided in the battery. This is not a big problem if the inside of the device is open to the atmosphere, but if the device has a sealed structure for waterproofing, etc., the released gas may be absorbed into the device. There is a risk that hydrogen gas may explode due to switch contact arcs or motor commutator arcs within the equipment, damaging the equipment or causing harm to humans. For this reason, in the past, the use of rechargeable batteries in devices with sealed structures has been avoided.

Further, in this embodiment, the exhaust hole 62 for opening the sealed space inside the main body housing 1 to the atmosphere by connecting the charging adapter 70 is arranged adjacent to the recess 49 where the terminal 25 is located on the bottom surface of the main body housing 1. It is provided. The exhaust hole 62 is always closed by the valve stem 63 of the lever 26, and is opened by connecting the charging adapter 70. An O-ring 64 is attached to the valve stem 63 at one end of the lever 26. O
The exhaust hole 62 is closed by the ring 64 contacting the tapered surface of the upper surface of the valve seat 68 whose diameter has been reduced, and the return spring disposed between the valve shaft portion 63 and the protruding piece 22 of the base 2 closes the exhaust hole 62. 65 and was spring biased into the closed state. The valve stem portion 63 and the return spring 65 are arranged in series in the axial direction, so that the spring force of the return spring 65 is applied to the valve stem portion 6.
3, so that it acts reliably in the axial direction. On the other hand, the charging adapter 70 that supplies the charging current is the third
As shown in the figure, it is connected to the bottom surface of the main body housing 1, and includes a terminal receiving part 72 that fits into the recess 49 and is connected to both terminals 25, and a terminal receiving part 72 that protrudes adjacent to this terminal receiving part 72. The boss 71 pushes up the valve shaft portion 63 against the return spring 65 to open the exhaust hole 62. At this time, the lever 26 positions the thin insulating piece 27 at its upper end between the switch spring 29 and the contact lug 30, so that the motor 6
Cut off the power to the A holding piece 28 provided on the lever 26 serves as a vertical sliding guide together with the base 2.

Thus, the gas generated from the battery 7 and flowing into the main body housing 1 without being discharged from the discharge port 48 is converted into water by the catalyst 61 applied to the outer surface of the casing of the motor 6. Further, during charging, the exhaust hole 62 is opened by the charging adapter 70, so that the gas is discharged to the outside from the exhaust hole 62. Even when the exhaust hole 62 is opened, some gas remains around the anode portion of the battery 7 due to the diffusion effect due to the difference in gas concentration. A further portion flows toward the motor 6 through the minute gap between the partition piece 21 and the inner surface of the main body housing 1, but it reacts with the catalyst 61 applied to the outer surface of the casing of the motor 6 and becomes water. . Therefore, the pressure in the space inside the main body housing 1 is maintained at the same level as the outside pressure, and there is no possibility that gas will remain inside and cause an explosion due to switching arc or commutator arc of the motor 6 during the next use. do not have. Charging adapter 70
If the valve stem 63 is removed, the return spring 65 will release the valve stem 63 to the exhaust hole 62.
is closed, and at the same time, the insulating piece 27 is lowered below the contact portion, making it possible to turn on and off using the switch handle 12.
