いようになつている。 As this type of brake mechanism, the one shown in FIG. 1 has been known. In this brake mechanism, a torsion spring b is disposed in a brake housing a so as to be in pressure contact with the inner wall of the housing a, and a torsion spring b is provided integrally with the pinion to resist rotational force from the pinion side. Claw part c
presses the hook portion of the torsion spring b and expands the outer diameter of the torsion spring b, so that the pressing force between the torsion spring b and the housing a becomes strong, and rotation of the pinion is prevented. On the other hand, the torsion spring b
receives a force in the direction of reducing the outer diameter, so the core e
can be rotated. Therefore, the pinion can be rotated via the torsion spring b and the claw c. That is, rotation can be transmitted from the handle shaft side, but rotation cannot be transmitted from the pinion side.

させ、フイーリングを悪化させていた。 By the way, in this brake mechanism, after the hook portion b 1 or b 2 of the torsion spring b is wound in a certain amount, transmission of rotation from the handle shaft side to the pinion side starts. Therefore, it is necessary to provide a gap corresponding to this amount of winding between the pawl c of the pinion and the hooks b 1 and b 2 of the torsion spring b, but in reality, this amount of winding is It is necessary to provide a gap for absorbing product processing errors that is much larger than the gap corresponding to . By the way, this gap causes play in the rotational direction of the pinion and also causes a large play in the driven gear that meshes with the pinion, thereby deteriorating the feeling.
本発明は、この問題に鑑みてなされたもので、
その目的は、上記ピニオン側のガタがほとんど発

The purpose is to provide a brake mechanism in which play on the pinion side hardly occurs.

る。 FIG. 2 is an exploded perspective view of an embodiment of the present invention, which includes a single torsion spring. In the figure, reference numeral 1 denotes a core consisting of two core members 2 and 3, and cutouts 2a and 3a are formed in the peripheral wall of each core member 2 and 3, respectively. One core member 3 is fixed to the handle shaft 4 in the preparation stage of assembly, and the large diameter portion 4a on the core member 2 side of the handle shaft 4 protruding from the core member 3 is provided with knurling, serrations, etc. It is engraved. Reference numeral 5 designates a torsion spring mounted so as to press against the inner wall of the housing 6, and reference numeral 7 designates a pinion having a claw portion 7a inserted between hook portions 5a and 5b of the torsion spring 5.

る。 This brake mechanism is assembled as follows. First, after mounting the torsion spring 5 in the housing 6, the handle shaft 4 integrated with the core member 3 is inserted into the housing 6, and one end face (for example, 3b) of the notch 3a of the core member 3 is inserted into the housing 6.
is brought into contact with the hook portion 5a of the torsion spring 5 (see FIG. 3). Next, the core member 2 is positioned in such a manner that the end surface 2b of the notch 2a is in contact with the hook portion 5b of the torsion spring 5.
Press fit into the large diameter portion 4a of the handle shaft 4 (see Fig. 4). As a result, the end surfaces 3b, 2b and the hook portions 5a, 5b of the torsion spring 5 come close to each other (abut or face each other with an extremely small gap). Then, remove the pinion 7 from its pawl 7.
a is the hook portion 5a, 5 of the torsion spring 5;
It is inserted into the handle shaft 4 so that it is located between

とになる。従つて、ツメ部７ａを介してピニオン
７が回転する。尚、コア１の時計方向への回転の
場合も同様である。 The braking operation in the brake mechanism having the above configuration is essentially the same as that in FIG. That is,
When the core 1 is rotated counterclockwise in FIG. 2 by operating the handle shaft 4, the end surface 3b of the core member 3 is brought into contact with the hook portion 5a of the torsion spring 5.
Press to reduce its outer diameter. When the core 1 is further rotated, the hook portion 5a of the torsion spring 5 hits the pawl portion 7a of the pinion 7, pushing the pawl portion 7a. Therefore, the pinion 7 rotates via the claw portion 7a. The same applies to the case of clockwise rotation of the core 1.

る。従つて、ピニオン７の回転が阻止される。 On the other hand, from the pinion 7 side to the claw portion 7a,
Regardless of whether rotational force is applied in the clockwise or counterclockwise direction, the hook portion 5a or 5b of the torsion spring 5 is pushed by the claw portion 7a, and the outer diameter of the torsion spring 5 is expanded. ,
A large braking force is generated due to frictional force between the torsion spring 5 and the inner wall of the housing 6. Therefore, rotation of the pinion 7 is prevented.

6 and 6 show the present invention applied to a double torsion spring type brake mechanism already filed by the applicant of the present invention. In this figure, parts corresponding to those in FIG. 2 are given the same reference numerals. This brake mechanism includes two parts installed in the housing 6 so as to be in pressure contact with the inner wall of the housing 6.
The hook portions 5 1 b, 5 2 b at one end of the two torsion springs 5 1 , 5 2 are connected to the slits 7 b, 7 b of the claw portions 7 a,
7c, the hook portions 5 1 b, 5 2 b
is engaged with the claw portion 7a, and when rotational force is applied to the pinion 7, the outside diameter of the torsion spring 51 or 52 is expanded to generate a braking force. By configuring the core 1 with two core members 2 and 3 as in the case shown in the figure, the end surface 2b of the core member 2 and the hook portion 52a of the torsion spring 52 can be brought into contact with each other or with an extremely small gap. In addition, the end surface 3b of the core member 3 and the hook portion 51a of the torsion spring 51 can be placed in contact with each other or in opposition with a very small gap between them.

The two may be combined by . Also, the 8th
As shown in the figure, a rectangular hole and an arcuate elongated hole may be formed in the core members 2 and 3, respectively, and a plate-shaped pin 9 having a tapered tip may be driven into these to connect the two. Furthermore, as shown in FIG. 9, the core members 2 and 3 are provided with knurled elongated holes and protrusions, respectively.
