したり、また入点を有していた。In recent years, vinyl chloride resin rain gutters have become mainstream as synthetic resin rain gutters, but vinyl chloride resin rain gutters have a higher coefficient of linear expansion than other rain gutters such as metal rain gutters. As a result, they elongate in the longitudinal direction due to direct sunlight in the hot summer sun, and as a result, joints of eaves gutters, such as curved gutters, are pushed up and damaged, or have intrusion points.

提案されるに至った。Therefore, reinforcing materials with a low coefficient of linear expansion, such as metal sheets, are inserted into the inner surface or middle part of the rain gutter body made of vinyl chloride resin, as seen in JP-A No. 55-122954, etc., to prevent expansion and contraction due to heat. Something that was made to force me to do something,
A rain gutter made of vinyl chloride resin has been proposed in which the coefficient of linear expansion of the composition itself is reduced by adding a filler such as a high calcium carbonate filling as seen in JP-A-55-122954. .

き鋭意研究を重ねた結果、本発明に到達した。[IIB to be solved by the invention] However, the former type of rain gutter made of vinyl chloride resin has problems in inserting reinforcing material into the gutter body during molding and adhering the reinforcing material to the gutter body. On the other hand, in the case of the latter, there is a natural limit to the amount of filler added due to moldability and physical properties. For example, when calcium carbonate is used as a filler, usually vinyl chloride resin 10
As a result of intensive research based on the knowledge that the coefficient of linear expansion can be reduced by adding 4 to 7 parts by weight to 0 parts by weight, the present invention has been achieved.
