A visual camera bearing structure includes: a shaft body, having a top end portion and bottom end portion; a through hole, configured inside the shaft body, one end of the through hole being in communication with the bottom end portion of the shaft body, another end thereof the top end portion of the shaft body, and the top end portion formed with a lens barrel accommodation opening; and a barrel lens support having a larger diameter, configured on an outer peripheral wall of the top end portion of the shaft body. Whereby, the barrel lens support is allowed to support the lens accommodation portion having a large area stably, thereby overcoming the condition of conventional visual cameras being difficult to be configured with a barrel lens having a large area.
