Power tool

SUBJECT of the Invention Since the multifunctional electric tool called a multi tool carried out the high-speed rocking|fluctuation of the front-end tool attached to the output shaft by fixed angle， it had a problem which the abutting surface of the housing of a halving structure rubs mutually by a microvibration， and heat|fever-generates. It aims at suppressing the heat_generation|fever of an abutting surface periphery of the housing of a halving structure in this invention. PROBLEM to be solved A relative displacement control means 71 to control the relative displacement of the abutting surface of split housing 50L， 50R is provided. In the thread connection part 60 of the upper side which is separated from a front-end tool among the thread connection parts 60 of the several places of split housing 50L， 50R， the displacement of the radial direction with respect to the boss|hub receiving part 62 of the screw boss|hub part 61 is controlled rather than the lower thread connection part 60， The rub of the mutual abutting surface of split housing 50L， 50R in the upper part of the grip part housing 53 is suppressed.
