[Problems to be solved by the invention]
In order to solve such a problem, for example, as shown in FIG. 6, a metal mounting plate 20 is installed at the plastic actuator 10, and further, the cable 50 is inserted into the mounting plate 20. The tip of the cable 50 is inserted into the small hole 250 having such a configuration, and the cable 50 is temporarily mounted. There is a type in which the cable 50 is mounted (fixed) by mounting a fixing metal 30 such as an end and caulking the fixing metal 30. By the way, this method has an advantage that the number of parts is small and the structure is simple, but there is a problem that the work of caulking the fixing bracket 30 is complicated. That is, in performing this caulking work, the tension of the cable 50 is kept constant in a state where the neutral state of the operation lever to which the other end of the cable 50 is attached is determined, and further, in such a state, The fixing bracket 30 must be installed at the mounting plate 20 with no gap, and the fixing bracket 30 thus installed must be crimped. Therefore, the caulking operation must be performed in a narrow space and in a state where the fixing bracket 30 is in close contact with the mounting plate 20, and there is a problem that the workability is not good. In order to solve such a problem, a cable in which the position of the fixing bracket is fixed in advance is prepared, and by using such a cable, the cable can be connected to the actuator. SUMMARY OF THE INVENTION It is an object (problem) of the present invention to provide a cable-type mirror control device which does not require adjustment of a neutral position after mounting.
