• the guide roller is pressed with resilience to the direction in which it is contact with the projected line portion (the direction indicated by the arrow R in the drawings) by a means which is not shown in the drawings.
• the concave groove 116 of the guide roller 106 engages the projected line portion 83 of the door sash frame 80 so that the guide roller 106 can move along of the projected line portion 83, thereby guiding the entire tool. Therefore, when the projected line portion 83 is straight as shown in Figure 7 (b), the concave groove 116 is in contact with the projected line portion 83 and the guide roller 106 can smoothly move along the projected line portion 83. However, when the projected line portion 83 curves, the direction of the concave groove 116 of the guide roller 106 does not coincide with the direction of the projected line portion 83.
• the projected line portion 83 cannot be in contact with the bottom of the concave groove 116, but floats, thereby hindering stable running of the guide roller 106.
• the guide roller 106 sometimes runs off the projected line portion 83.
• the adhesive tape application tool 1 of the present invention guide rollers having a tapered shape portion which forms a slope from the bottom toward the top are used as a guide roller of the guidance part 6 being in contact with the projected line portion 83 instead of conventional guide rollers with a concave groove.
• one guide roller having a tapered shape portion does not engage the projected line portion.

• the guidance part 6 is provided with the guide rollers having a tapered shape portion 16, 17.
• the guide rollers having a tapered shape portion 17 positioned at both ends are installed with the top directed in one direction (downward in the drawing) and the central guide roller 16 having a tapered shape portion is installed with the top directed in the other direction (upward in the drawing).
• This configuration ensures that fluctuation of the door sash frame 80 provided with the projected line portion 83 and the adhesive tape application tool 1 provided with the guide rollers having a tapered shape portion 16, 17 in the vertical direction shown in Figure 6 (b) is suppressed by means of the three guide rollers having a tapered shape portion 16, 17 in both the area where the projected line portion is straight and the area where the projected line portion curves, whereby the adhesive tape application tool 1 can smoothly and consistently move along the projected line portion.
• the tool has four guide rollers having a tapered shape portion, for example, when the guide rollers having a tapered shape portion positioned at both ends and two guide rollers having a tapered shape portion positioned therebetween are installed facing in opposite directions, the guide rollers having a tapered shape portion cannot be adequately operated in a curve and may run off the grooves as in the case of conventional tools, although straight run stability may be improved.
• the central guide roller having a tapered shape portion 16 be installed swingably to the direction of the center axis, i. e.
• the central guide roller having a tapered shape portion 16 is preferably installed with a certain allowance. This configuration can improve operability at a curve. Even if the door sash has the form of a curve with a small radius or steeply curves at a corner, the adhesive tape application tool 1 can move steadily, with the guide rollers having a tapered shape portions 16, 17 maintaining contact with the projected line portion 83.
• the central guide roller having a tapered shape portion 16 moves upward along the center axis (the SI direction in the Figure) when the tool travels from the area where the projected line portion 83 is straight as shown in the Figure 4 to the area where the projected line portion 83 curves as shown in the Figure 5.
• This configuration ensures that the guide rollers having a tapered shape portion 16, 17 maintain contact with the projected line portion 83 and the adhesive tape application tool 1 steadily moves along the projected line portion 83.
• the guide rollers having a tapered shape portion are installed so that the direction from the bottom to the top is in the order of downward, upward, and downward.
• the present invention is not limited to this embodiment.
• the adhesive tape application tool 1 of this configuration is an embodiment allowing the projected line portion to curve to the right (the direction shown by the projected line portion 83 in Figure 5). If the tool is to be designed to allow the projected line portion to curve in the opposite direction, the guide rollers having a tapered shape portion should be installed so that the direction from the bottom to the top is in the order of upward, downward, and upward.
