Suction port body for electric vacuum cleaner and electric vacuum cleaner having the same

The present invention provides a suction port body for an electric vacuum cleaner, which prevent relative rotation of housing relative to a connecting pipe when the housing is taken from ground and can cause the connecting pipe to easily rotate relative to the housing when loading to ground is performed, and the electric vacuum cleaner with the suction port body. A ground brush (23) is provided with the following components: a housing (31) which extends in a left-and-right direction; a rotating pipe (32) which is connected relative to the housing (31) in a manner of rotating around an axis; and a rotation stopping member (62) which is movably configured for the housing (31) and contacts with the rotating pipe (32) on condition that the housing (31) is separated from the ground, thereby preventing relative rotation of the rotating pipe (32) relative to the housing (31), and furthermore releasing a state of preventing the relative rotation of the rotating pipe (32) relative to the housing (31) on condition that
