被駆動側部材との連結のために利用される。[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to a connection structure for thin rods, and more particularly, the present invention relates to a connection structure for thin rods, and specifically, for transmitting rotational torque between a driving member and a driven member via a thin rod. It is used to connect the thin rod of the mechanism to the driving or driven member.

なつている。(Prior art and its problems) Transmitting the rotational torque of a driving member to a driven member via a thin rod is used in many fields including the toy industry. The problem with this transmission mechanism is the connection between the thin rod and the driving or driven member. Conventionally, the ends of thin rods are squared, the ends of the thin rods are inserted into square holes in the driving or driven member, and both are caulked to prevent idling. However, as the torque is transmitted repeatedly, the angular end of the thin rod becomes rounded and eventually spins around. For this reason, when transmitting large torque, it is necessary to increase the diameter of the thin rod to prevent the corners from collapsing. This is extremely fatal, and is the reason why torque transmission mechanisms using thin rods are not used in toys.

する。(Technical means of the present invention and its effects) In order to solve the above-mentioned problems, the present invention provides a flat end of the thin rod and a gap between the pair of claws of the connecting member on the driving or driven member side. The flat end of the thin rod is inserted into the thin rod, and the nail and the end of the thin rod are covered with a collar.

耗もなく、細棒の空廻りもない。 The adoption of this means means that the rotation of the thin rod is transmitted to the claws that are in contact with the flat surface of the thin rod, but since the claws are in contact with the inner peripheral surface of the collar and their movement is restricted, the free rotation of the thin rod is prevented. Therefore, large torque can be reliably transmitted from the driving member to the driven member via the thin rod. In particular, since the end of the thin rod and the claw of the connecting member are in flat contact, there is no wear and there is no idle rotation of the thin rod.

が後述する細棒４の平坦面部５を受ける。(Example) Please refer to FIGS. 1 and 2. A connecting member 2 is fixed to a driving or driven member 1. This fixation is accomplished, for example, by knurling the member 1 and press-fitting or caulking the member 1 into the central hole of the connecting member 2. A pair of claws 3 is extended from the end of the connecting member 2. The claw 3 is manufactured by cutting the connecting member 2,
Its outer surface is a tapered surface that becomes thinner toward the tip. As shown in FIGS. 1-2, the claw 3 has a space between its opposing inner wall surfaces, and this space receives a flat surface portion 5 of a thin rod 4, which will be described later.

要はない。 A collar 6 is arranged to surround the claws 3 of the connecting member 2 and the flat surface portions 5 of the thin rods 4 between the claws 3. The collar 6 has a tapered inner surface 7 that approximately matches the tapered surface of the claw 3 of the connecting member 2.
has. Thus, when the collar 6 is inserted into the connecting member 2 along the outer peripheral surface of the claw 3, the tapered surface 7 of the collar 6 pushes the claw 3 inward, strongly pushing the claw 3 and the flat surface portion 5 of the thin rod 4 together. Bring it into close contact. Therefore, it is not necessary to have high manufacturing tolerances for the dimensions between the claws 3 and the thickness of the flat surface portion 5.

断を防止する。 When connecting the round thin rod 4 and the connecting member 2, insert the flat surface portion 5 of the round thin rod 4 between the claws 3 of the connecting member 2, and connect these claws 3 and the flat surface portion 5 with the collar 6. surround. As a result, the flat surface portion 5 comes into close contact with the claw 3,
The claw 3 is in close contact with the tapered inner surface 7 of the collar 6. Thus, the rotational torque applied to the thin rod 4 is reliably transmitted to the driving or driven member 1 without any play. Also, the tapered inner surface 7 of the collar 6 of the claw 3
The close contact with the nail 3 prevents the nail 3 from breaking due to stress acting on the nail 3.
尚、細棒４の平担面部５の巾寸法は、爪３の巾
寸法に合せるとよい。 The width of the flat surface portion 5 of the thin rod 4 is preferably matched to the width of the claw 3.

い。(Effects) According to the present invention, large torque can be transmitted even if the thin rod has a diameter of 2 mm, and torque can be transmitted without increasing the weight of the toy. The end of the thin rod is simple because the only work required is forging the flat surface, there is no wear due to use, and the rod is highly durable and reliable.
