To provide construction equipment which can suppress the overflow of a surplus sealing agent from a sealing agent application area defined by a mounting surface formed on an upper revolving body and a mounting surface formed on a housing of a revolving device.

The sealing agent application area 43 for sealing the periphery of a pinion insertion hole 13 formed in a revolving frame 8 is defined by the frame-side mounting surface 14 formed on the revolving frame 8 and the housing-side mounting surface 24 formed on the housing 22 of the revolving device 21, and the frame-side mounting surface 14 has an entire peripheral groove 44 formed thereon for accommodating the surplus sealing agent 43A overflowing the sealing agent application area 43. Thus even if the surplus sealing agent 43A overflows the sealing agent application area 43, it is trapped in the entire peripheral groove 44, and therefore the flowing of the surplus sealing agent 43A into bolt holes 15 screwed in the frame-side mounting surface 14 and bolt insertion holes 25 formed in the housing-side mounting surface 24 can be suppressed.
