As described above, according to the present invention, there is provided a mounting structure for a main rope support in which a main support made of a pipe material is mounted on a body to be mounted so as to protrude upward through a clamping jig. The holding jig is formed in a C-shaped cross section and is fixed to the attached body at an opening thereof, and the holding jig has a pair of mounting pieces arranged to face each other. Are connected in an upwardly protruding manner, while a reinforcing core is inserted into the hollow portion at the lower end of the main rope support, and the lower end of the main rope support is inserted between the mounting pieces. At the same time, the lower end of the reinforcing core is connected to the clamping jig by concave and convex fitting, and in this state, the two mounting pieces, the main rope support, and the reinforcing core are fastened by a fastening member. The two mounting pieces, the main rope support and the reinforcing core are fastened. In this state, the reinforcing core is inserted into the hollow at the lower end of the main rope support, so that the lower end of the main rope support is reinforced by this reinforcing core, and thus the lower end of the main support is supported. Will not be unintentionally dented or bent. In addition, since the lower end of the reinforcing core is connected to the holding jig, the main rope support is connected to the holding jig via the reinforcing core and both mounting pieces. Becomes Therefore, it is possible to provide a mounting structure for the main rope support, in which the main rope support is firmly connected to the clamping jig.
