The detailed structure will be described later. The sheet heating element 2 is placed on the bottom portion of the cap 6, the soaking plate 3 is placed on the sheet heating element 2, the cap 6 is put on from under the eaves gutter 1, and the locking portion 5 is placed.
The planar heating element 2 and the heat equalizing plate 3 are attached to the outer surface of the eaves gutter 1 by locking the locked portion 7 to the eaves gutter 1. The lead wire 8 is drawn out from between the cap 6 and the eaves gutter 1 to the side to supply electric power. The lead wires 8 of the planar heating element 2 are connected to each other via a connector or the like at the portion where the longitudinal ends of the eaves gutter 1 are connected by joints. When the sheet heating element 2 is energized, the heat of the sheet heating element 2 is transferred to the eaves gutter 1 through the heat equalizing plate 3 to heat the eaves gutter 1, and the snow that has entered the eaves gutter 1 is melted. . FIG. 3 shows another embodiment, in which the cap 6
An elastic heat insulating material 9 is interposed between the sheet heating element 2 and the sheet heating element 2. When the heat insulating material 9 is interposed, the sheet heating element 2
It is possible to prevent the heat from the outside to be dissipated to the outside, and the elasticity of the heat insulating material 9 allows the cap 6 to be attached to the eaves gutter 1 without rattling. The caps 6 may extend over the entire length of the eaves gutter 1 in the longitudinal direction, or a plurality of caps 6 may be attached at appropriate intervals in the elongate direction of the eaves gutter 1. Further, although the sheet heating element 2 and the heat equalizing plate 3 are attached to the outer surface side of the eaves gutter 1 in the above embodiment, they may be attached to the inner surface side of the eaves gutter 1.
