題が生じていた。<Background Art> In an electric tool such as an electric screwdriver, a case is formed in a tubular shape, and a battery storage portion is provided at one end of the case to detachably store a storage battery pack.
At this time, in order to store the storage battery pack, one end of the case on the side of the battery storage portion is also formed in a tubular shape. However, when the case is made as thin as possible, the following problems occur.
すなわち、ケースを合成樹脂の成形品として形成する場

体としての小型化に制限を与える上に、意匠的にもあま
り好ましいものではない。That is, when the case is formed as a molded product of synthetic resin, conventionally, as shown in FIG. 3, the entire case 1 is composed of a pair of halves 18,18, but the case is made as small as possible. Storage battery pack 2 when making it thin
In the battery storage unit 10 for storing the battery pack, since the storage battery pack 2 having substantially the same diameter is provided inside thereof, it is necessary to form the protrusions 19 and 19 on the case 1 in order to connect the two halves 18 and 18. Screw 6
Since it is not possible to provide the insertion portion of the above, these projections 19 and 19 limit the miniaturization as a whole, and are not very preferable in terms of design.

たものより、悪くなってしまう。As shown in FIG. 4, a case 1A formed of a pair of halves 17 and 17 is formed into two halves, and a case 1B formed into a tubular shape and having one end connected to the case 1A. If the cylindrical case 1B side is used as the battery housing portion 10, the case 1B can be made to have a slender shape having substantially the same diameter as the storage battery pack 2, but at this time, the case 1 has three parts. In addition, the shape of these parts becomes complicated with the above-mentioned connecting portion, and the assembling property becomes worse than that shown in the conventional example.
〈考案の目的〉 本考案はこのような点に鑑み為されたものであって、そ

うにしたものである。<Disclosure of the Invention> However, the power tool according to the present invention is provided with a case in which one end side is a battery storage section and the other end side is a storage section for a drive mechanism including a motor and a speed reducer. The main case, which has a tubular shape on one end side that is the storage section and the other end side that is the storage section of the drive mechanism, is one half of the split case, and the other half body of the split case that is the main case described above. The main case is formed of a sub case that is combined with the other end side, and the main case in which the end face opening on the one end side is the battery mounting portion and the sub case that is combined with the main case are respectively included in the gear case of the speed reducer. It is characterized in that it is screwed and integrally connected through a gear case, and the housing side of the drive mechanism in the case is divided into two parts and is connected by screwing to the gear case of the speed reducer of the drive mechanism. ,battery The storage part is designed to be cylindrical from the beginning.
以下本考案を図示の実施例に基づいて説明すると、この

だけで形成されたものとなっている。The present invention will be described below with reference to the illustrated embodiment. In this case, as shown in FIG. 2, a storage battery pack 2, a motor 3 and a speed reducer are provided in a tubular case 1 bent in a V shape. An electric screwdriver that accommodates 4 and the like, and the case 1 is formed of two parts, a main case 11 and a sub case 12,
Only the first half of the case where the motor 3 and the speed reducer 4 are housed is divided into two parts consisting of these cases 11 and 12, and the battery compartment 10 of the latter half that houses the storage battery pack 2 is the main case 11.
It has been formed only.
すなわち、主ケース11はその一端側が筒型に、他端側が
断面半円形に形成され、この他端側は断面半円形の副ケ
ース12と組み合わされることによって、筒状となるもの
である。That is, the main case 11 has a tubular shape at one end side and a semicircular cross section at the other end side, and the other end side becomes a tubular shape by being combined with the sub case 12 having a semicircular cross section.
ケース１が主ケース11と副ケース12との２部品からなる

It is possible to make the slender body almost the same as that of No. 2 and at the same time, the protrusions and the like do not project to the outside. In addition, the above cases 11 and 12 are connected to each other in the sub case 1
Screw hole 1 that is inserted from 2 and is provided on the inner surface of the main case 11.
3 and a screw 16 that is fastened to a screw hole 15 provided in the gear case of the speed reducer 4 from each of the cases 11 and 12. In other words, for parts that do not have a drive mechanism, connect the main case 11 and the sub case 12 with the screw 14
The drive mechanism housing portion in the case 1 is also connected to the motor 3 and the speed reducer because the portion where the drive mechanism is present is coupled to the gear case by screwing together. The gear case of the machine 4 can be kept to have the same diameter as that of the gear case.

Therefore, it is possible to make the battery as thin as the battery to be stored in the battery storage part, and for the storage part of the drive mechanism in the case, divide these into two parts and reduce these to the speed reducer of the drive mechanism. Since it is connected via the gear case of, the diameter of the gear case of the motor and drive mechanism can be made to be almost the same, and the overall size can be kept to a minimum and the number of case components can be reduced. It has a small number of parts and has good assemblability, and because the drive mechanism storage part in the case is 20%, it is easy to assemble the drive mechanism and maintainability in case of failure. Is something that can be kept at.
