Abstract
A reclining device of a seat for a vehicle is disclosed. With the disclosed device it is possible to prevent unexpected pivot of a seatback and improve the passenger's safety by maintaining the engagement of a sector tooth 20 and a pawl tooth 70 even if the pawl tooth 70 is separated from a rotational center protrusion 11 by a relatively large external force applied to the seatback.

A reclining device of a seat for a vehicle comprising:
- a cam lever (50) that is disposed between a plate holder [10) and a sector tooth (20) to be elastically rotated by a cam spring (60) and through which a shaft (40) passes;
- and
- a plurality of pawl teeth (70), each pawl tooth (70) having a protrusion groove (71), which is fitted around a rotational center protrusion (11) of the plate holder (10) to make a seesaw-type rotation while contacting with the cam lever (50) that rotates, and have both sides (72, 73) that face a circumferential direction of the plate holder (10) and are guided by a guide protrusion (12) of the plate holder (10), wherein pressing protrusions (72a, 73a) and fitting grooves (72b, 73b), which are engaged with the guide protrusion (12) when each pawl tooth (70) is separated from the rotational center protrusion (11) by an external force, are continuously formed on both sides (72, 73) of the pawl tooth (70).
