The invention aims to provide an artificial nipple for a nursing bottle which permits close fitting of the nipple to the sucking fossa of an infant while avoiding deformation of the nipple while providing a form that is similar to a human nipple, and which can prevent the upper and lower sides of the nipple from contacting each other during peristalsis-like movements. In view of this, the present invention provides an artificial nipple for a nursing bottle having: a nipple top part having at its tip a dispensing hole for dispensing a liquid drink; and an artificial nipple body which is continuous to the nipple top part, and whose diameter and wall thickness are greater than those of the nipple top part. The artificial nipple is made of a flexible material. The nipple top part has a rib, which prevents contact between an upper side and a lower side of the nipple top part when the nipple top part is compressed flat, at a portion where gums of an infant touch when an upper lip of the infant is in contact with the artificial nipple body or at an internal surface in the vicinity of the portion.

An inner sole structure 3 for a sports shoe 1 includes an upper sheet member 30 disposed on an upper side of a heel region of the shoe 1, a lower sheet member 31 disposed below the upper sheet member 30, and a wavy corrugated sheet member 32 that is interposed between the upper sheet member 30 and the lower sheet member 31, that has at least two downwardly protruding protrusions 32a, 32b adapted to form voids V₀, V₁′, V₁ with the upper and lower sheet members 30, 31, and that is in contact with an upper surface 31a of the lower sheet member 31. Each of downwardly convex portions 32a₁, 32b₁ of the protrusions 32a, 32b of the wavy corrugated sheet member32 slides longitudinally on the lower sheet member 31 at the time of compressive deformation of the protrusions 32a, 32b.

The damper unit 10 is applicable to structures for seismic energy dissipation. The damper unit 10 comprises, a lower beam 11, an upper beam 12, a left column 21, a right column 22, axially yielding dampers 41, 42 functioning as an energy dissipating means, a left post-tensioned steel bar 31, and a right post-tensioned steel bar 32. The left and right post-tensioned steel bars 31 and 32 are inserted in the left and right columns 21 and 22, respectively. Upper ends of the steel bars 31 and 32 are connected with the upper beam 12. Lower ends of the steel bars 31 and 32 are connected with the lower beam 11. The columns 31 and 32 are semi-rigid connected with the upper beam 12 and the lower beam 11 by compressive forces generated from the steel bars 31 and 32. Therefore, the damper unit 10 possesses both self-centering and seismic energy dissipation characteristics.

A grommet mounted in a through-hole in a vehicle body panel and through which a wire harness is passed. Even if taping only one side, the grommet shape is retained and the grommet is prevented from deforming in the direction in which an engaging recess of the grommet separates from the peripheral edge of the through-hole. The grommet comprises: an enlarged-diameter tube which connects to the outer periphery of the longitudinal intermediate section of a small-diameter tube through which wires are tightly passed, and which is enlarged in diameter to surround the other side of the small-diameter tube; an engaging recess which is annularly formed in the outer peripheral surface of the enlarged-diameter tube on the large diameter side thereof; inner ribs provided at intervals in the circumferential direction and connecting between the inner periphery of the enlarged-diameter tube and the outer peripheral surface of the other side of the small-diameter tube; and wire insertion tubes which connect to through-holes for wires formed in the enlarged-diameter tube and which extend through the inside of the enlarged-diameter tube and project from the opening end on the large-diameter side. The inner ribs stick out with a clearance from the inner peripheral surface of the enlarged-diameter tube from the position where the enlarged-diameter tube contacts the inner peripheral surface of the through-hole of the vehicle body panel to a position facing the engaging recess.

A vehicular air-bag lid having a three-layer structure including an outer skin (6), a foaming layer (7), and a core material (8). Substantially square door members (13) are fitted within an opening (12) and are opened about a hinge portion at the time of air bag inflation. A pair of substantially triangular-shaped, in plan view, recessed bead portions (30) project toward the undersides of the respective door members (13). A reinforcing plate (31) accompanies the whole recessed bead portion on the surface side of each door member (13). Each recessed bead portion (30) has two of its three sides respectively disposed along the side of a door member (13) and along a hinge portion.

An insertion tool of an intraocular lens of novel structure in which the intraocular lens can be deformed into smaller one while rotation of the intraocular lens in an insertion tube is effectively prevented. Upper and lower flat planes (25, 26) are formed to spread flatly over an entire length of a through hole (22) in the insertion tube (20) and the upper and lower flat planes (25, 26) are connected smoothly with right and left wall faces (30, 28) over the entire length of the through hole (22). At least a part of the through hole (22) in an extending direction thereof, the right and left wall faces (30, 28) have longitudinal linear portions extending substantially in parallel in a vertical direction on a proximal end opening (23) side. On the other hand, with its radius of curvature decreasing gradually in a covered shape which becomes inwardly concave as it approaches a distal end opening (24), the upper flat plane (25) is allowed to gradually approach the lower flat plane (26), and a tapered portion having a reduced cross-sectional area is formed, thus obtaining the distal end opening of substantially oval shape.
