By this, the weir portions (21) are caused to be gradually inclined outwards and removed, and the windowpane holder (1) and the windowpane (14) are adhered to each other by the adhesive agent, to produce a vehicle window assembly (15).

A stringed instrument including strings supported by bridges, which are fixed to a body, and a nut fixed to a neck. The strings are supported in a manner enabling vibration of each string. The nut includes a nut body and a fastener. The fastener is formed by pressing members and adjustment screws. The pressing members press the strings against the nut surface so that the strings are fixed to the nut surface. A projection projecting toward the strings is formed on an end portion of the nut. The strings are supported by the nut so as to contact the top surface of the projection. This enables each string to vibrate while being in constant contact with the projection and prevents each string from coming into contact with the nut or fastener. Thus, abnormal noise is not generated.
