PROBLEM TO BE SOLVED: To realize the spherical seal support oil interceptor of an inertial cone crusher by which the scattering of oil to the outside is prevented, and the contamination is also prevented. SOLUTION: A raw ore is crushed between a conecave 6 and an eccentrically rotating mantle 16 in this inertial one crusher. In this case, an oil-thrower groove 20 is annularly provided on the contact face between a spherical seat 7 and a conehead 15 slightly within the outer periphery of the seat 7, an oil hole 21 for discharging oil downward is furnished at plural spots of the groove 20, an annular protrusion 22 with the tip close to the conehead 15 is provided to a spherical seat support 2 at a specified distance from the outer periphery of the seat 7, a groove 23 is furnished to the inner base of the protrusion 22, and an oil relief hole 24 is provided to liberate the oil downward from the groove 23.
