とを特徴とするアームレスト構造。 In an armrest structure in which an armrest main body is rotatably supported relative to a seat back and a locking mechanism is provided that allows the armrest main body to be freely positioned at a selected rotational position, the locking mechanism is a gear fixed to a pivot shaft and It consists of a lock plate that is attached to the armrest body and is removable from the gear, and the lock plate is provided with a pair of protrusions that engage with the gear, and the spacing between the protrusions is set so that the distance between the protrusions is equal to the width of the teeth of the gear. It is characterized in that it is formed from a 3/2 pitch, and when the armrest main body is rotated by 1/2 pitch with respect to the toothed portion of the gear, one of the projecting pieces of the lock plate is locked to the toothed portion of the gear. Armrest structure.
