Description of the Related Art As for a drive unit having a built-in reduction gear, which requires manual operation, various improvements have been made because the operation force from the load side becomes a problem. In FIG. 5, a drive motor 5 and a speed reducer 4 are provided inside the housing 1 to transmit power to a load 9, and a manual operation knob 11 is operated via a speed increasing device 10 for manual operation in an emergency. It is connected to the drive motor 5 to reduce the operation force when the load 9 is directly operated manually.

破損等の問題を派生するようになっていた。FIG. 6 is a prior application of the present inventor: Japanese Patent Application No. 7
146970 is a schematic cross-sectional view of an example in which a planetary gear mechanism is used in the speed reducer described in detail in FIG. Unlike the speed reducer composed of rows, the reverse operation from the load side is easy and the manual operation can be performed easily with a small force. However, especially when the driving electric motor 5 is a DC electric motor having a permanent magnet, etc. Since the driving electric motor 5 generates a high back electromotive force due to the high speed rotation of the rotor by the operation from the side, problems such as damage of a control circuit (not shown) for controlling the electric motor have been derived. .

制動装置６が併設されることが多い。As described above, by using the planetary gear mechanism 4-1 for the speed reducer 4, the operation from the load 9 side is facilitated, but the reduction of the friction torque on the drive side reduces the load 9 to a predetermined value. When the braking / holding force is required, the driving electric motor 5 is not limited to an electric motor such as an induction motor having no holding force in the rotor and the above-mentioned DC Even in the case of an electric motor, a braking device 6 is often provided alongside the driving electric motor 5.

FIG. 1 shows an embodiment according to the present invention, in which a reduction gear 4 installed in a housing 1 has a planetary gear mechanism 4-1 as a main structure and internal teeth arranged at the outermost peripheral portion thereof. As shown in FIG. 3, the gear 4-11 has the housing 1
A circumferential groove 4-112 is formed in the outer peripheral surface 4-114 loosely fitted to the inner peripheral surface 1-2 of the cylindrical portion, and a concave portion 4-111 is formed in the internal gear end surface 4-113.

両者の当接面の凹凸が離接自在に構成されている。As described above, the housing 1 and the internal gear 4-11 are slidably fitted to the inner peripheral surface 1-2 and the outer peripheral surface 4-114, respectively. The operating means 7 is configured so that the unevenness of the contact surface between the two is freely contactable.

負荷装置９を駆動することができる。FIG. 1 is a schematic cross-sectional view showing a state in which the housing 1 and the internal gear 4-11 are coupled to each other, and a connecting / disconnecting operation engaged with a groove 4-112 on the outer peripheral surface of the internal gear shown in FIG. By the means 7, the internal gear 4-11 is pressed to the right in the figure,
The concavities and convexities of both the housing 1 and the internal gear 4-11 are fitted together. In this state, the driving DC motor 5
It is possible to drive the load device 9 through the planetary gear mechanism 4-1 by appropriately energizing the load device 9.

けを回転させる力しか要しないことになる。The release of the coupling between the housing 1 and the internal gear 4-11 is to make the internally mounted planetary gear mechanism 4-1 rotatable inside the housing 1, and is directly operated from the load side. In the above, only the force for rotating only the rotatable planetary gear mechanism 4-1 having no fixed holding portion is required.

力も発生せず制御回路を破損する恐れもない。Needless to say, if the rotational friction torque of the drive motor 5 itself is larger than the rotational friction torque of the planetary gear mechanism 4-1, the rotor gear of the drive motor 5 meshes with the input gear of the planetary gear mechanism. Since the driving electric motor 5 does not rotate only by the rolling engagement in the section, the friction torque of the driving electric motor does not affect the external operating force. Further, since the driving DC motor 5 does not rotate, back electromotive force is not generated and the control circuit is not damaged.

As shown in FIGS. 1 and 2, the operating end portion is configured to operate integrally with the opening / closing means 8 of the braking device 6 that is provided with the driving electric motor 5.
