Abstract:
To connect end parts of spacer members of double glazing to each other so as to obtain required connection strength while using a connection member made of resin.SOLUTION: A spacer (4) for a double glazing (1) includes: spacer members (11) whose end parts (11a) are abutted on each other at end faces and which extend in a cylindrical shape; and a resin-made connecting member (12) which connects the abutted end parts of the spacer members in a state of being housed inside the spacer members. The spacer members cooperate to form the cylindrical shape and includes a resin spacer piece (20) and a metal spacer piece (30) which form a part of the cylindrical shape in a circumferential direction. The metal spacer pieces are equipped with stacking marks (31c) which are dented by stacking on surfaces of their end portions, and the connection members are equipped with transfer marks (45c) which are dented and overlap the stacking marks in a state where the dents are transferred to the stacking marks. If the connecting member has stripes (45a), the width of the stripes can be widened by stacking, thus improving the connection strength.SELECTED DRAWING: Figure 1
