Abstract: A parting surface structure of a bulletin device having a device frame, includes an open bearing portion in the device frame, a parting surface body formed as a front face of the device frame, the parting surface body including a pivot for pivotally mounting the parting surface body in the open bearing portion, and an abutment member in the open bearing portion for preventing removal of the pivot, the abutment member being rotatable with the pivot in the open bearing portion.

Abstract: A parting surface structure of a bulletin device for indication or decoration in station yards, underground passages, buildings, exhibitions, etc. has an adjustable construction. A fitting slot is formed in the inner peripheral edge of a parting surface body which constitutes the front face of a device frame, and a second parting surface portion having a desired parting surface width is fitted in the said fitting slot. According to this construction, part of the parting portion can be replaced with a parting surface portion having a desired parting surface width according to a bulletin to be used in a manufacturing factory or at a site where the bulletin device is mounted. Thus, it is possible to make adjustment freely to a parting surface width suitable for a bulletin to be used.
