PROBLEM TO BE SOLVED: To enable the motions of start and stop of advance and retreat of a vibration roller body and the timings of the start and stop of a vibration exciting device to be easily adjusted on a user's side. SOLUTION: An oscillating plate 18 can be integrally oscillated integrally with a pivot 19 in such a manner that the pivot 19 for controlling a control valve for traveling serves as a supporting point. The oscillating plate 18 is formed in such a manner as to be oscillatable in accordance with the operating direction of a traveling lever. A limit switch 26A is arranged in the state of being close to the recess 22A which is provided in the oscillating plate 18. In this traveling and vibration control unit of the vibration roller, the pivot 19 is rotated by the oscillation of the oscillating plate 18, so that the start and stop of the advance and retreat of a vibration roller body can be controlled; and the limit switch 26A engages/disengages the recess 22A so as to bring about an on-state and an off-state, so that the start and stop of the vibration exciting device can be controlled. Strikers 20a and 20b are provided in the oscillating plate 18 in such a manner as to be positionally adjustable with respect to an oscillating direction. The recess 22A, which is formed of the strikers 20a and 20b, can be positionally adjusted with respect to the oscillating direction of the oscillating plate 18. COPYRIGHT: (C)2008,JPO&INPIT
