1. A scroll compressor comprising:
a fixed scroll including:
a wrap accommodation portion having an inner space extending inside the wrap accommodation portion,
a thrust surface formed around the inner space,
a fixed wrap extending downward into the inner space, and
an oil groove formed on the thrust surface;
an orbiting scroll configured below the fixed scroll and to rotate with respect to the fixed scroll, the orbiting scroll including:
a mirror plate,
an orbiting wrap extending from an upper surface of the mirror plate so as to engage with the fixed wrap of the fixed scroll,
at least one oil supply groove on the upper surface of the mirror plate so as to face the thrust surface of the fixed scroll, and
a first oil hole configured on the upper surface of the mirror plate to supply oil to the oil groove of the fixed scroll; and
a driving motor configured to rotate the orbiting scroll,
wherein the orbiting scroll is configured so that:
when the orbiting scroll rotates, the at least one oil supply groove of the orbiting scroll moves from a first position to receive oil from the oil groove of the fixed scroll to a second position to supply the oil to the inner space of the wrap accommodation portion of the fixed scroll, and the first oil hole cyclically crosses the oil groove of the fixed scroll.
