FIELD: transport engineering.SUBSTANCE: invention relates to a casing of a production machine, primarily to that of a hand-held machine. The casing comprises two separate parts connected to each other by a coupling device made as a swivel pad. The swivel pad provides for turning of the connected casing parts in respect to each other. At least one casing part is fitted by a withdrawal channel leading to the swivel pad and meant for impurities withdrawal. The withdrawal channel runs at least, in essence, in radial direction and opens to the flow passage for cooling air formed in the casing.EFFECT: smooth jamless sliding of swivel pad parts and extended service life of the swivel pad.9 cl, 5 dwg |
