PURPOSE:To attain high-accuracy adhesion with simple with simple constitution and to enhance the performances, such as temp. characteristic and heat resistance, by adhering only the insertion part by an adhesive to the inside wall of a cylindrical body and housing and disposing a holding member into the cylindrical body, thereby constituting the above device. CONSTITUTION:The holding member 10 is housed and disposed into the cylindrical body 12 by adhering only the insertion part to the inside wall of the cylindrical body 12 by the adhesive 13, by which the optical coupling device is constituted. The thermal stress of a temp. change is thereby prevented from being imparted axially to the adhesive 13 adhering the holding member 10 and the inside wall surface of the cylindrical body 12 when the temp. change arises and, therefore, the adhering state of the holding member 10 and the inside wall surface of the cylindrical body 12 is assured. The peeling of the adhesive 13 arising from the temp. change is, therefore, surely prevented and the desired characteristic and heat resistance are assured. The high-accuracy adhering is attained with the simple constitution in this way and the performances, such as temp. characteristic and heat resistance are enhanced. |
