To obtain the subject simple type device capable of controlling temperature without depending upon a hand, compact and slight in burden of facilities, by forming a greenhouse space from a covering member equipped with an opening and a closing parts opening and closing by a driving element responding in two directions, composed of a shape memory alloy and an elastic material at an upper part and/or a lower part.
An upper part and/or a lower part of a covering member 2 is equipped with an opening and closing part 3 opening and closing by a driving member 5 responding in two directions, composed of a shape memory alloy and an elastic material. A semicylindrical greenhouse space 7 such as vinyl greenhouse is formed from the covering member 2. The opening and closing part 3 is opened at a temperature equal to or above a set temperature and the opening and closing part 3 is closed at a temperature equal to or below the set temperature to adjust a room temperature.
