Generally, a seat of an automobile is provided with a seat cushion which supports a load of a passenger and is movable in a front-rear direction with respect to a floor of a room to support a lower body portion of a passenger, and a seat cushion And a seat back supporting the upper body portion of the passenger.

Such a seat is provided with a sliding device for the driver or the occupant to adjust the front and rear positions of the seat by pulling or pushing the seat cushion forward and backward in accordance with the body shape of the driver or the occupant, and a sliding device for adjusting the inclination angle of the seat back with respect to the seat cushion, A manual recliner device for variably controlling the angle of the seat back with respect to the seat cushion is provided.

As a conventional recliner device, there is an example of a recliner for an automobile seat disclosed in Japanese Patent No. 10-1422419. In the conventional recliner device as described above, when the operation lever is pivoted, So that the inclination angle of the seat back with respect to the seat cushion can be freely adjusted. In this case, the rotational force provided to the operation lever is transmitted to the cam through the rotation shaft, and the rotational force transmitted to the cam actuates the pole tooth to release the engagement with the sector tooth.

2, the holder plate 200 and the sector tooth 300 constituting the core assembly are connected to the operation cams 400 and 400, respectively, as shown in FIG. 2 of Patent Document 10-1422419, And the front periphery of the outer circumferential surface of the coupling portion between the holder plate 200 and the sector tooth 300 is enclosed by the guide ring 700. [

In addition, the holder plate 200 is configured to radially arrange the guide embosses 210 corresponding to the guide blocks, and guides the side portions of the pole teeth 500, The guide emboss 210 maintains the inclination angle of the seat back through intimate contact with the pole tooth 500, thereby enhancing the safety of the passenger.

However, the conventional recliner device having the above-described structure is manufactured in a more compact structure in response to the weight reduction of parts. For example, the overall diameter of the core assembly is reduced and the thickness of each component constituting the core assembly is also set to be thin The space occupied by the parts is reduced as well as the weight is reduced.

However, in the case of the conventional recliner device manufactured in accordance with such a lightweight trend, the proper structural rigidity is ensured between the pole tooth 500 and the guide embossment 210 of the holder plate 200 in case of an external force such as a rear impact, There is a technical limitation in manufacturing a recliner device in which the ultra-lightweight, high-strength durability performance can be guaranteed without changing the volume, weight and material of the parts.

In consideration of the fact that the guide embossment 210 formed on the holder plate 200 greatly contributes to maintaining the inclination angle of the seat back through contact with the pawl 500 when an external force such as a rear impact is applied, Since the total volume of the recliner device is inevitably set to be large in order to secure a large number of the guide embosses 210 formed on the plate 200, the result is that the parts can not meet the weight reduction trend, And development of a new technology capable of securing the durability of the recliner device without changing the weight and the material has been demanded.
