機構。[Scope of Claim for Utility Model Registration] (1) At the rear of the focus plate holder that holds the focus plate of a single-lens reflex camera, a retaining bent part and a position regulating bent part are provided at a distance in the width direction of the holder. Each of the prism sheets is bent to support the pentaprism located above the focusing plate, and the stopper portion is located above the bending portion to prevent the focusing plate holder from coming off, and 1. A holding mechanism for a focusing plate holder of a single-lens reflex camera, characterized in that a holding part is formed in contact with a lower part of a position regulating bending part of the focusing plate holder to determine a holding position of the focusing plate holder. (2) In claim 1, the focusing plate holder retaining bending part and the corresponding stopper part of the prism sheet are provided at the center of the focusing plate holder in the width direction, and the same position regulating bending part and the corresponding stopper part are provided at the center of the focusing plate holder in the width direction. The holding portion is a holding mechanism for a focus plate holder of a single-lens reflex camera, which is provided at both ends of the focus plate holder in the width direction.
