摘要:
A seat height adjustment apparatus includes a stepped portion provided on a bottom plate of a seat and formed in a stepped configuration, an adjust member removably attached to the stepped portion and having a lower face placed on a seat rail for adjusting the height between the seat rail and the seat, and vehicle body side fixing members provided on the seat rail for abutting with an abutting portion to fix the adjust member. Upon seat height adjustment, adjustment of the seat height can be carried out simply only by replacing the adjust member to an arbitrary stage of the stepped portion. Further, since the seat height adjustment apparatus is formed from the three parts of the stepped portion, adjust member and vehicle body side fixing member, the number of parts is reduced.

To easily prevent flapping of a cover attached to a vehicle such as a motor cycle. A storage box is provided on a lateral side of a vehicle frame. The storage box includes a storage box main body having an opening facing an outside of a vehicle, and a lid member which is openable and closable to cover the opening. A side cover which covers a lateral side of the vehicle is provided in front of the storage box. A rear edge portion of the side cover extends to an outside edge portion of the storage box main body, and is fixed to the outside edge portion.

A liquid ejection head is disclosed. The liquid ejection includes a flow channel plate, the flow channel plate being formed from one thin plate, the flow channel plate being formed with one or more pressure generating chambers, a fluid resistance section which supplies liquid to the pressure generating chamber, and a nozzle hole which opposes the pressure generating chamber. The flow channel plate is made of a metal material, and wherein the flow plate includes the pressure generating chamber which is formed of a groove-shaped indentation; the nozzle hole which is formed at one end in a longitudinal direction of the groove-shaped indentation; and the fluid resistance section which is formed at the other end in the longitudinal direction of the groove-shaped indentation. The pressure generating chamber, the nozzle head, and the fluid resistance section are formed such that they deform the thin plate in a thickness direction.

A method for producing cold-rolled steel sheets which comprises the steps of: producing slabs containing 0.001-0.003 wt. % C, 0.004 wt. % or less N and 0.03-0.20 wt. % P, providing that P(wt. %).times.N(wt. %).ltoreq.3.times.10.sup.-4 wt. % is satisfied; hot-rolling the slabs into hot-rolled steel strips; cold-rolling the hot-rolled steel strips at 60-95% reduction ratio into cold-rolled steel strips; and annealing continuously the cold-rolled strips at temperature of recrystallization temperature to Ac.sub.3 transformation point temperature. The slabs further include 0.0005-0.0030 wt. % B. The hot-rolling is performed at finishing temperature ranging Ar.sub.3 transfromation point to Ar.sub.3 transformation +100.degree. C., at cooling temperature of 750.degree. C. and less.
