To provide a door closing device that can easily pass through an insertion slot, into which the door closing device is inserted, to be installed at an installation position even when an opening/closing-directional dimension of the insertion slot is relatively small as compared with a conversion part, and a method for attaching the door closing device.SOLUTION: A door closing device 100 comprises: a drive source 1; and a conversion part 5 which includes a pinion gear 51 and a rack part 52 arranged to be engaged with the pinion gear 51 and moving linearly as the pinion gear 51 rotates, and converts rotational driving force of the drive source 1 into opening/closing-directional linear movement of a door body 6. The conversion part 5 is configured to be able to split at least one of one opening/closing-directional end part and the other opening/closing-directional end part of the conversion part 5.SELECTED DRAWING: Figure 1

    【課題】戸閉装置が挿入される挿入口の開閉方向の寸法が、変換部に対して比較的小さい場合でも、戸閉装置が容易に挿入口を通過して設置位置に設置されることが可能な戸閉装置および戸閉装置の取付方法を提供する。【解決手段】この戸閉装置100は、駆動源1と、ピニオンギヤ51と、ピニオンギヤ51に係合するように配置され、ピニオンギヤ51の回転により直線移動するラック部52とを含み、駆動源1の回転駆動力を戸体6の開閉方向の直線移動に変換する変換部5とを備える。変換部5は、変換部5における開閉方向の一方の端部と、変換部における開閉方向の他方の端部との少なくともいずれかを分割可能に構成されている。【選択図】図1
