Abstract: A glass run for use in a motor vehicle, of which corner sections are readily manufactured with excellent sealing properties. A main body of each of straight sections and corner sections of the glass run has an outer side wall, an inner side wall and a bottom wall, which define a generally U-shaped cross-section, and an outer seal lip and an inner seal lip are respectively provided in the outer side wall and the inner side wall. The straight sections and the corner sections are joined to each other via joints, and the inner side wall is formed greater than the outer side wall. A sub-seal rib is provided to protrude outwardly from an exterior surface of the outer side wall of each of the corner sections so as to face a position in which an end of the outer seal lip contacts the outer side wall when the door glass contacts the outer seal lip.

Abstract: A rotor blade for a helicopter having: a main blade with a blade root attached to a rotor shaft of the helicopter; and a small blade attached to a blade tip part of the main blade, wherein a tip part of the small blade is rectangular form in its plane shape, and has a leading edge continuous with a leading edge of the main blade and a chord length shorter than a chord length of the main blade.

Abstract: A sealing structure for sealing between a sliding roof and an opening portion of a roof panel of a motor vehicle. The sealing structure includes an annular frame member which is secured along the opening portion of the roof panel, an annular roof panel main seal for contacting a lower surface of a periphery of the sliding roof when the sliding roof is closed, and a roof panel sub-seal for contacting side edges of the sliding roof when the sliding roof is closed. The roof panel main seal and the roof panel sub-seal are attached to the annular frame member.

Abstract: An attachment structure of a weather strip having a base portion and a tubular seal portion to an opening portion of a motor vehicle or a periphery of a closing member for opening and closing the opening portion. The attachment structure includes a channel part having a U-shaped cross-section and including side walls provided in the opening portion of the motor vehicle or the periphery of the closing member to define a channel. The base portion of the weather strip includes an inserting part adapted to be inserted in the channel and a holding part for holding one of the side walls with the inserting part. The inserting part and the holding part define a slot. The inserting part includes a holding lip which projects from an end of the inserting part obliquely outward.
