PURPOSE:To enable the adjustment at one time of incident angles and reflection angles of plural mirrors that reflect light successively and the transmission of light of large outputs by providing said plural mirrors and gear mechanisms for adjusting said incident and reflection angles. CONSTITUTION:A joint for optical transmission pipes is provided with plural mirrors 21-24 which reflect light successively and gear mechanisms having gears 11-18 which adjust the incident angles and reflection angles of the mirrors by rotating and connecting the mirrors successively. According to such gear mechanisms, the incident light A entering the central part of, for example, a pipe 25 through the opening at the other end thereof reflects successively on the mirrors 21 22 23 24 and finally the light as reflected light B emits from the other pipe 26 by passing through the central part thereof. With such joint for optical transmission pipes, the incident angles and reflection angles of the plural mirrors that reflect light successively are thus be adjusted at one time and the light of large outputs is transmitted. |
