PROBLEM TO BE SOLVED: To improve work efficiency of a hand-held type drive-in tool for a fixed element. SOLUTION: The hand-held drive-in tool for a fixed element includes a driving device 30 for a drive-in plunger 13 displaceable in a guide 12, a tensible drive spring element 31 by at least one transmission belt 33 through at least one bias force generating device 70 for guiding at least one transmission belt 33 by a roller 34 provided on at least one bearing element 35, and rotatably supporting at least one roller 34 at the bearing element 35 with a rolling bearing 40. It is preferable that at least one guiding means is provided at the roller 34 to guide the transmission belt 33 onto the roller 34 at the central part in an axial direction. It is more preferable that the two guiding means are constituted as guiding rods 46 provided at the ends of the roller 34 in the axial direction. COPYRIGHT: (C)2009,JPO&INPIT
