A tiltable headrest device is provided to suppress the occurrence of abnormal noise during rotation, to reduce the number of components and to improve appearance quality. Guide portions () each comprising a standing-up locking portion (), a falling-down locking portion () and a rail portion () are integrally formed on a core member (), a coil spring () for urging a lateral rod () toward a direction approaching the guide portions () is provided in the core member (). The lateral rod () is pressed to the guide portions () by the urging force of the coil spring () so as to be guided. Due to sliding contact between resin and metal, the occurrence of abnormal noise can be prevented.

Tiltable headrest device

An arm-rest device is constituted by including the following: an armrest body to be installed to a seat rotatably upward/downward; a ratchet mechanism including stationary-side first ratchet teeth, and movable-side second ratchet teeth rotating integrally with the armrest body; coiled springs for urging those in such a direction that they press one another; releasing cam units for releasing the ratchet mechanism from the meshing; elastic claws and a flanged portion for retaining that release; cut-offs for returning the ratchet mechanism to the meshing. And, the armrest body is made of resin, thereby integrally molding the second ratchet teeth at the time of its molding. It thus becomes an armrest device that is lightweight as a whole, whose assembly can also be done with less man-hour requirements, whose feeling of use is also satisfactory, and which is inexpensive and small in size.
