Definitions
- the present invention relates to a rotary connector device. Specifically, the present invention relates to a configuration for reducing noise generated in the rotary connector device.
- Patent document 1 discloses this kind of rotary connector.
- the rotary connector device of Patent Document 1 includes a first case that rotates integrally with a steering wheel, and a second case that does not follow the rotation of the steering wheel.
- a steering shaft insert
- these cases form an annular space inside, and a flexible flat cable for electrically connecting the steering side member and the vehicle body side member is disposed in the annular space.
- the first case has a rotator and a sleeve.
- the rotator is fixed to the steering shaft so as to rotate integrally with the steering.
- the sleeve is fixed to the rotator by a snap fit. In this configuration, when the steering shaft rotates, a force is transmitted from the steering shaft, so that the rotator rotates, and the sleeve rotates accordingly.
- the second case includes a stator and a sub-stator.
- the stator is fixed to the steering column so as not to follow the steering rotation.
- the sub-stator is fixed to the stator by a snap fit method. With this configuration, the stator and the sub-stator do not rotate even when the steering shaft rotates.
- the sleeve is in contact with the stator, and the rotator is in contact with the sub-stator.
- the first noise is generated from the part where the rotator and the sleeve are connected to each other. That is, the steering shaft includes not only the force in the rotational direction of the steering shaft but also the force in the axial direction of the steering shaft (the direction in which the steering is pushed or pulled) and the radial direction of the steering shaft (the direction in which the steering is translated). Power may be applied. As a cause of this, for example, there may be a bias in the operation force applied by the driver to the steering wheel.
- the second noise is generated from a portion where the stator and the sub-stator are mutually connected, and is generated by the same principle as the first noise. That is, when an axial force or a radial force is applied to the steering shaft in the same manner as described above and the rotator is strongly pressed against the sub-stator, a relatively large friction is generated between the rotator and the sub-stator. Due to this friction, a large force is applied to the connection portion between the sub-stator and the stator, so that the connection member (for example, the claw portion) on the sub-stator side and the connection member (for example, the receiving portion) on the stator side rub against each other, resulting in noise (stagnation sound). Will occur.
- the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rotary connector device that reduces noise during rotation even in a situation where a force other than the rotational direction is applied to an insert (for example, a steering shaft). There is to do.

- the first rotating member has a connecting portion and a cylindrical portion, and can be attached so as to rotate integrally with an insert inserted into the cylindrical portion.
- the second rotating member has a connected portion connected to the connecting portion, and is attached to the first rotating member so as to rotate integrally with the first rotating member.
- the fixing member has a second cylindrical part, and is attached so as not to follow the rotation of the insert inserted into the second cylindrical part and to be in contact with the second rotating member.
- the material constituting the connecting portion and the connected portion is a combination that can suppress the generation of the squeaking noise that occurs when they rub against each other.
- the connecting portion and the connected portion are fixed by fitting one into the other.
- the configuration (snap fit) that is fixed by fitting one into the other is excellent in mounting workability, but since the fixing force is not so strong, the connecting portion and the connected member are easily rubbed. Therefore, by using the combination of the above materials, the effect of the present invention that suppresses the generation of itching sound can be more effectively exhibited.
- the rotary connector device has the following configuration. That is, the fixing member includes a first fixing member and a second fixing member.
- the first fixing member has a second connecting portion and can be attached so as not to follow the rotation of the insert.
- the second fixing member has a second connected portion connected to the second connecting portion, and is attached to the first fixing member so as not to rotate relative to the first fixing member. It arrange
- the material constituting the second connecting portion and the second connected portion is a combination that can suppress the generation of the squeaking noise that occurs when they are rubbed against each other.
- the second connecting portion and the second connected portion are fixed by fitting one into the other.
- the configuration (snap fit) that is fixed by fitting one into the other is excellent in mounting workability, but because the fixing force is not so strong, the members easily rub against each other. Therefore, by using the combination of the above materials, the effect of the present invention that suppresses the generation of itching sound can be more effectively exhibited.
- the same material is used as a combination of materials capable of suppressing the generation of stagnation noise.
- the squeaking sound generated between different materials is smaller than the squeaking sound generated between the same kind of materials.
- the noise generated when the first rotating member and the second rotating member are rotated in a situation where force is applied can be further reduced.
