The present invention provides a waterproof structure of electronic equipment, which is capable of simply and properly waterproofing the electronic equipment which can operate via a bolt through-hole formed in a housing of the electronic equipment. The waterproof structure of the electronic equipment comprises: an operated object (3) suffering a pressing operation in a direction intersecting a wall surface of an electronic equipment housing (1), and a bolt through-hole (4) being independent of a bracket opening and penetrating the electronic equipment housing (1); and the electronic equipment capable of performing the pressing operation to the operated object (3) from the outside of the electronic equipment via the bolt through-hole (4), which has an operating bolt being capable of moving and received in the bolt through-hole (4). A ring-type waterproof component (6) made of flexible material engages with the outer periphery of the operating bolt (5). A gap between the inner surface of the bolt through-hole (
