2. Description of the Related Art Conventionally, a glass plate is frequently used for a window material to be installed on a roof or a wall surface of a building. When a glass plate is arranged side by side, for example, as shown in FIG. As shown in Conventional Example 1 shown, a mounting groove (32) having a U-shaped cross section for inserting a window material (W) such as a glass plate is provided on both left and right sides, and a zipper insertion groove (33) is provided at the center of the upper surface. 2. Description of the Related Art A zipper gasket (31) made of an elastic long-shaped material having a structure adapted to be attached to an object frame (39) is known. The zipper gasket (31) inserts the window material (W) into the mounting groove (32), then inserts the zipper (34) into the zipper insertion groove (33), and fixes the upper and lower wall surfaces of the mounting groove (32). It is a structure that is mounted so as to be pressed against the surface of the window material (W). The zipper gasket (3
1) mounting grooves (35) provided on both sides of the lower part thereof
Is attached by inserting a mounting plate-like tongue (39a) of a frame material (39) previously attached to a building.

However, since the mounting groove (32) is formed in the zipper gasket (31) of the first conventional example, the mounting groove (32) is required when the window material (W) is mounted. It is necessary to push and insert the window, the operation is very troublesome, and the insertion position of the insertion edge (e) of the window material (W) cannot be seen, and it is difficult to check the allowance and the insertion gap. There's a problem. In particular, when a synthetic resin window material (W) is applied, the window material (W) due to a temperature change is used.
Because of the large expansion and contraction of these, it is desired to solve such a problem.

[0004] In order to solve the problem of the first conventional example,
For example, as shown in Conventional Example 2 shown in FIG. 4, a zipper gasket main body (41) is made of a main gasket (42) having a T-shaped cross section for pressing an end surface of a window material (W) and a window material (W). Left and right auxiliary gaskets with trapezoidal cross section supporting the back of the end (4
3) Divided into three parts of (43) and the main gasket (4)
2) A zipper insertion groove (45) for inserting a zipper (44) is provided at the center of the front surface, and a movable hook having a substantially U-shaped cross section is provided at the center of the back surface at the center of the frame material body (49) of the building. A hook leg (42a) to be fitted to the portion (49a) is vertically provided, and fitting recesses (49b) (49b) (left and right sides) of the frame material body (49) are provided on the back surface of the sub gaskets (43) and (43). 49b) provided with projections (43a) and (43a) to be fitted thereto is disclosed in Japanese Utility Model Registration No. 2583983.

[0005] However, according to the conventional example 2, even if the thickness of the window material (W) to be installed varies, the position of the movable hook (49a) with respect to the frame material body (49) is connected to both. Although it is possible to adjust the bolts and nuts to cope with this, and to solve the above-mentioned respective problems according to the conventional example 1, the structure of the frame material body (49) is complicated, the production cost is increased, and the cost is uneconomical. . In addition, the movable hook (49
Since the inner surface of a) and the outer surface of the hook leg (42a) are provided with a stepped portion which is fitted to each other and serves to prevent slippage,
Once fitted, the hooking leg (42a) cannot be easily pulled out, and has the disadvantage that it is difficult to visually check the hooking margin and insertion gap of the window material (W) again.
