摘要：

A cylindrical structure is formed by a cylinder and a terminal engaging member, such as a gear or flange for rotating the cylinder, fastened to at least one end of the cylinder. The terminal engaging member has a head inserted into the cylinder and a recess adjacent to the head and is fastened to the at least one end of the cylinder by bending and cutting an end brim of the associated cylinder end into the recess of the terminal engaging member. The cylindrical structure is characterized by the joint between the cylinder and the terminal engaging member, which joint can be formed securely in a simple manner. The cylindrical structure may be embodied, e.g., as a photosensitive drum or a developing sleeve for electrophotography.

摘要（中）：

圆柱形结构由气缸和端子接合构件形成，例如用于旋转气缸的齿轮或凸缘，紧固在气缸的至少一端。 端子接合构件具有插入到气缸中的头部和与头部相邻的凹部，并且通过将相关联的气缸端部的端部边缘弯曲并切割到端子接合构件的凹部中而紧固到气缸的至少一个端部 。 该圆柱形结构的特征在于缸和端子接合构件之间的接头，该接头可以以简单的方式牢固地形成。 圆柱形结构可以被实施为例如感光鼓或用于电子照相的显影套筒。
