ABSTRACT:
In a guide device for cutting a groove of this invention, a rectilinear guide member (10) comprises a pair of guide members (11, 12), where the opening width (W.sub.1, W.sub.2) of an opening (26) defined between the guide members (11, 12) is set to be the same as the diameter of a rotary bit of a router (22). A dado (2) having a width that is the same as the thickness of a board to be used as a shelf is formed by operating the router (22) with a scrap piece of that board (3a) inserted between the guide members (11, 12) to get an accurately cut dado.
