例）がある。(Prior Art) The Zenmai of the Zenmai drive device, which uses the release force of the Zenmai as a driving source, has its inner end connected to the Zenmai winding shaft, and its outer end locked to a fixed member. There is. The full-length drive device can be divided into two types depending on the manner in which the outer end of the full-length drive is connected to the fixed member.The outer end is bent into a U-shape and the outer end is engaged with a fixed member such as a pin to lock the drive device. As installed in the Mai motor (first example) and the toy known by the trade name Chiyoro Q, an inward recess is formed in the peripheral wall of the Zenmai storage section and a bend is made at the outer edge of the Zenmai storage section. This is known as a pullback motor (second example) in which the protrusion formed by the process is engaged with the concave part, and a music box drive source in which the ear part formed at the outer end is engaged with the metal frame. There is a barrel (third example).

なくなる、という問題が発生する。(Problems to be Solved by the Invention) In the first example and the second example, it is necessary to bend the outer ends of the full length, which increases the cost of the full length itself. Also, in the first example, when wrapping the Zenmai around the Zenmai upper shaft and rolling it into the Zenmai storage section,
If the outer end and the fixing pin do not engage well, a problem arises in that the outer end gets caught in the storage part, making it impossible to fix the outer end.

れている。 To wind up the full length 7, the output shaft 5 is rotated clockwise in FIG. 1, and the gear 5 is rotated in the same direction. The rotation of the gear 5 is achieved by rotating the intermediate gear 10 counterclockwise to move the planetary gear 11 counterclockwise, which is then transferred to the small diameter gear 8b of the sun gear 8.
mesh with. When the sun gear 8 is rotated, the full winding upper shaft 6 engaged with the recess 8c and its arm 6b is rotated to wind up the full winding 7 and store its energy. When the sun gear 8 rotates counterclockwise, the planetary gear 9 meshing with the large-diameter tooth portion 8c of the sun gear 8 is planetarily moved in the same direction and interlocks with the intermediate gear 10, as shown in FIG.

止する。 Zenmai 7 when winding of Zenmai 7 is completed,
The engaging step portion 1u is inserted through the ear portion 7c of the neck portion 7b.
A force in the direction indicated by the symbol P in FIG. 4 is applied to 2u. This force (P) acts in a direction that deforms the synthetic resin casing, but a part of this force is caused by the engagement with the engagement pin 1f in the vicinity of the full retraction window holes 1s and 2s. Engagement step portions 1u and 2 are connected and reinforced by fitting into the hole 2f.
It can be received in the direction indicated by the symbol P _u at u. Furthermore, the force applied to the engagement step portion 2u of the second casing 2 is
An attempt is made to deform the side wall of the casing, but this is achieved by the free end 2w of the side wall being brought into contact with the wall surface 1w of the first casing and backing up the free end 2w. Further, the first case 1 constituting the Zenmai storage section 1p tries to expand due to the expansion force of the released Zenmai, but this force is caused by the engagement pins 1e, 1g, 1h, 1i and engagement hole 2
An engaging portion 3e and an engaging hole 3e, 3 are connected to the second case 2 and each pin connected by e, 2g, 2h, 2i.
It is received by the middle plate 3 (see FIG. 1) connected at points g, 3h, and 3i, and prevents deformation of the casing.

避する。 If the winding operation by the output shaft 4 continues for the Zenmai hoisting shaft 6 which has stopped after the winding of the Zenmai 7 is completed, that is, if an overload is applied to the gear train of the hoisting system, the Zenmai hoisting shaft 6 will stop after the winding of the Zenmai 7 is completed. The arm 6b is elastically deformed to disengage the arm 6b from the recess 8c of the sun gear 8, thereby allowing the gear train to rotate freely, thereby avoiding overload.

８ｂとの噛み合いから解放されている。 Next, the effect when the Zenmai is unwound will be explained. When the winding operation by the output shaft 4 is stopped,
The Zenmai winding shaft 6 rotates the sun gear 8 in the clockwise direction by the accumulated force of the Zenmai 7, as shown in FIG. The rotation of the sun gear 8 causes the planetary gear 9 to move planetarily in the same direction, and the large diameter tooth portion 9b of the planetary gear 9 is moved toward the intermediate gear 1.
The output shaft 4 is rotated by rotating the gear 5 meshing with the small-diameter tooth portion 10a of 0 and the gear 5 meshing with the large-diameter tooth portion 10b in the direction of the arrow. When the planetary gear 9 transmits rotation, the planetary gear 11 of the hoisting system gear train
As the intermediate gear 10 rotates, the support holes 2d and 3
d and moves planetarily, and is released from meshing with the small diameter tooth portion 8b of the sun gear.

防止できる。(Effects of the Invention) As described above, according to the present invention, the outer end of the zeni can be locked to the casing without bending, so the processing cost of the zeni can be reduced.
In addition, since the synthetic resin casing has been carefully connected, deformation of the casing during full winding can be reliably prevented.

Claims

[Scope of Claim for Utility Model Registration] A synthetic resin casing consisting of a first case and a second case that are engaged with each other, a Zenbu stored in a Zenbu storage section formed inside the casing, and A winding that is provided between an output shaft rotatably supported by the casing and a full-length winding shaft whose inner end is connected, and transmits the rotation of the output shaft to the full-scale winding shaft. It consists of an upper system one-way transmission means and a release system one-way transmission means for transmitting the rotation of the full winding upper shaft to the output shaft, a narrow neck is formed at the outer end of the full winding, and the first Engage the neck of the full-length retractor pulled in through the window hole with the full-length locking part of the full-length retractable window hole formed by the opposing parts of the case and the second case so that it hangs over both of the cases. The first case and the second case are connected in the vicinity of the full retraction window hole, and the engaging pin and the engaging hole are fitted, and the neck portion is engaged with the free end of one case and the other. A full-movement drive device characterized in that it is coupled by contact with the wall of a case.
