Abstract: A work of incorporating a speed reduction mechanism including a scissors gear into a gear case is facilitated. In a state where the angular positions of gear teeth of a first gear and the angular positions of gear teeth of a scissors gear are made to coincide with each other against the elastic force of a torsion spring (19), these angular positions are fixed by a fixing member (position fixing step). The first gear, the scissors gear, and a second gear are housed in a gear case, and the gear teeth of the second gear are made to engage with the gear teeth of the first gear and the gear teeth of the scissors gear (gear incorporating step). The fixing of the angular position of the first gear and the angular position of the scissors gear by the fixing member is released through an opening formed in the gear case.

Abstract: A continuity checking apparatus generates a continuity checking packet to which a predetermined flag and user attributes are assigned and transmits the generated continuity checking packet to an edge router connected to a service that is an entrance of a service chain. Each service transmits an arrival message with respect to the continuity checking packet to the continuity checking apparatus upon reception of the continuity checking packet to which the predetermined flag is assigned. In addition, each service transfers the continuity checking packet to a next service device of the service chain on the basis of the user attributes assigned to the received continuity checking packet. The continuity checking apparatus identifies a path representing service devices through which the continuity checking packet passes on the basis of the arrival message transmitted from each service, and determines whether the identified path is the same as a path of the service chain that is a continuity checking target.
