とを特徴とする紙送りローラ。 In a paper feed roller that rotates integrally with a paper feed rotation shaft, the paper feed roller has a cylindrical lock guide body and a lock body that overlap each other, and the peripheral wall of the lock guide body at the overlapping portion is equally spaced in the circumferential direction. The lock body has a chuck compression engagement portion at a divided position, and the lock body contained in the lock guide body is divided in the circumferential direction corresponding to the chuck compression engagement portion of the lock guide body, and has a groove in the axial direction. The chuck pawl is compressively engaged with the chuck pawl through the chuck compression engaging portion due to the difference in rotational displacement between the two members, and the chuck compression engaging portion is provided between the lock guide body and the lock body. It has a positioning engagement part for relative positioning with the chuck pawl and for rotating and stopping by 180°/n (n: the chuck compression engaging part divided into equal parts and the number of chuck pawls). A paper feed roller featuring:
