Conventionally, writing instruments have been proposed in which two writing units are selectively projected into a writing position, or both writing units are retracted into a storage position. Since this conventional writing instrument does not have a means for positioning the writing unit in the writing position and the storage position, it is not possible to confirm these positions by touch or the like, which is inconvenient. Also, if both writing units cannot be positioned in the storage position, both writing units may not be stored securely after use.In this case, when storing the writing unit in a chest pocket, etc. There was a risk that the writing unit would rotate about the shaft and protrude into the writing position, and the lead or the like would stain clothing.
