Abstract: A stroller includes a chassis, a main body disposed on the chassis, and a first vibration-absorbing mechanism including a first rod structure, a first sleeve structure, a first inner elastic part, and a first outer elastic part. The first rod structure is connected to a side of the chassis. The first sleeve structure is connected to the main body and movably sleeves the first rod structure. The first inner elastic part abuts against the first rod structure and the first sleeve structure. When the first vibration-absorbing mechanism is in a first use state, the first outer elastic part is in contact with one of the first sleeve structure and the first rod structure. When the first rod structure slides toward the first sleeve structure over a specific distance, two ends of the first outer elastic part abut against the first sleeve structure and the first rod structure, respectively.

Abstract: The present invention relates to two braking devices employed in a baby carriage. The braking device includes a braking base, a braking wheel, a pad, a pad surface, a stop node and a linkage set. The linkage set connects to two braking devices. When the user step down the pad, the braking devices will be activated to a releasing mode. The baby carriage is therefore able to move. If the user steps down the linkage set, the baby carriage will enter into a braking mode. Thus the baby carriage will be secured and stopped.

Abstract: A stroller includes a stroller frame, a wheel unit mounted on the stroller frame, a resistance providing unit mounted on the stroller frame for providing resistance against rotation of the wheel unit, and a resistance adjusting member connected to the resistance providing unit for adjusting the resistance.

Abstract: A shock absorbing device is adapted for damping impact transmitted from a front wheel of a stroller. The device includes left and right lever members, left and right front leg members, a pair of coupling members, and a pair of biasing members. Each lever member has an anchoring end adapted to be secured to one end of a front wheel axle, and is pivotally mounted on the coupling member. Each front leg member has one end connected to a seat frame of the stroller, and the other end retained in the corresponding coupling member. The biasing members are disposed to bias engaged ends of the front leg members to move towards or away from intermediate portions of the lever members when tensioned or compressed.

Abstract: A device for slow speed and lightweight vehicles, which includes a body fixed on an underframe of the vehicle, a support articulated on the body, and a spring elastically linking the body and the support, wherein the spring is a composite strip fixed at one of ends thereof, to the body, and directly bearing, at a free end thereof, on the wheel axle.

Abstract: A nuclear fuel pin is formed of an elongated metallic tube, closed at each end, containing stacked fuel pellets and material including little, or no, fissionable material, and formed into porous, or bubbled, microspheres placed in the annulus between the pellets and the internal wall of the tube.
