A small swivel type working vehicle includes a running device ( 4 ), a swivel base ( 2 ) mounted on the running device ( 4 ) to be swivelable about a vertical swivel axis (X), a driver's seat ( 5 ) mounted on the swivel base ( 2 ), a control box ( 6 ) mounted upright on a top surface of the swivel base ( 2 ) forwardly of the driver's seat ( 5 ), a swing bracket ( 18 ) supported to be swingable about a vertical pivotal axis ( 19 a) by a flange unit ( 17 ) provided at a front end of the swivel base ( 2 ), a boom ( 20 ) attached to the swing bracket to be swingable about a horizontal shaft ( 22 ), and a boom cylinder ( 21 ) connected at one end thereof to the swing bracket ( 18 ) and at the other end to the boom ( 20 ) for swinging the boom ( 20 ). The boom cylinder ( 21 ) is disposed outside the boom ( 20 ) to extend along a rear surface thereof. A walk-through space ( 100 ) is defined between the control box ( 6 ) and the driver's seat ( 5 ). A distance (L 1 ) from the swivel axis (X) of the swivel base ( 2 ) to the vertical pivotal axis ( 19 a) is substantially the same as a distance (L 2 ) from the swivel axis (X) to a rear end of the swivel base( 2 ).
