This invention relates to an electronic component mounting apparatus. In the
apparatus, a rotary body for changing the direction of a component mounting section
is fixed to a hollow rotary shaft with a flange. The hollow rotary shaft is provided
in a hollow motor and rotated integrally with the rotary body by driving of the
hollow motor. A wire extending from an electric component, which is provided in
the rotary body for changing the direction of the component mounting section, is
arranged in the hollow rotary shaft of the hollow motor. An end of the wire is
fixed to the rotary body, and the wire is arranged with looseness or into a spiral
in the hollow rotary shaft. Further a lateral surface of inside the hollow rotary
shaft and a surface of a coupling shaft are coated with protective materials.
