A molding for a vehicle includes a molding body provided at a door of the vehicle, at least one light-emitting body provided inside an end portion of the molding body for notifying an occupant of a state of the door, and a light-transmitting portion provided at the molding body for transmitting light emitted by the light-emitting body.

A poppet valve moves up and down in a valve operating mechanism in an internal combustion engine. A fixed electrode is supported on a cylinder head, and a moving electrode is carried by the poppet valve. The fixed electrode is connected to a circuit, which together comprises a variable condenser and a resistance. The valve moves up and down during firing operation of the engine. Variation in electrostatic capacitance is detected by means of the two electrodes, transmitted to the circuit via a lead and a ground connection, and converted to a voltage by the circuit, thereby enabling detecting valve position more exactly.

An Al alloy tappet used in an internal combustion engine has a spiral groove on the outer circumferential surface of a tappet body. The spiral groove is formed by pushing a cutting tool against the outer circumferential surface and feeding it in an axial direction. Near the lower end of the tappet body, feed rate is decreased, and the cutting tool is moved away from the tappet body to form a smaller spiral groove which increases in diameter downwards. The outer circumferential surface of the tappet body is covered with a coating layer such as Fe, and the lower end which has the smaller spiral groove is chamfered.

Between the end of a valve and a valve-operating cam in an internal combustion engine, a valve lifter is inserted. A filler enclosing portion is formed between a shim and the body of the valve lifter. Through an opening from an injector, a filler is introduced into the filler enclosing portion, so that valve clearance is corrected to zero. Differences in valve clearance can be easily corrected.

A tappet made of Al alloy is used in a valve operating mechanism of an internal combustion engine of a vehicle. On the whole outer circumferential surface of the tappet, a helical projection and a helical groove are formed alternately to form an uneven surface. A plurality of uneven surfaces are formed on a ridge of the projection at regular intervals. The outer circumferential surface is coated with a wear resistant Fe film by thermal spraying. The uneven surfaces on the projection provide high adhesion strength of the film to the outer circumferential surface of the tappet to improve peel resistance, thereby increasing durability and reliability of the Al alloy tappet.

A tappet is used in an internal combustion engine. A cam-slidably-contacting member is placed on a top wall of a tappet body via diffusing material which comprises mixture of one or more elements of Zn, Mg, Sn, Cu and Pb. The cam-slidably-contacting member and the tappet body are pressed with the diffusing material held therebetween, so that the diffusing material is diffused into the tappet body and the cam-slidably-contacting member until a layer which comprises only the diffusing material does not substantially remain to form the tappet having high strength.

A window construction for vehicle includes a sash frame rectangular in shape for receiving glass panes in a window opening thereof, and a seal member secured to the sash frame and adapted to be mounted on a vehicle's body. The sash frame has a projection extending outwardly from the outer surface thereof, and the seal member has a recess or groove in which the projection is fitted. The seal member has one hook for gripping the edge of the inside wall of the sash frame and one abutment portion for abutment engagement with the edge of the outside wall of the sash frame.

A doorframe structure comprises an upper guide formed of metal plate so as to have an enclosed space extending in a longitudinal direction of the upper guide, the upper guide having a constant cross section, a weather strip channel extending in a longitudinal direction of the upper guide and fixed to the upper guide, a window glass guide, made of metal plate, arranged so as to be inclined relative to the upper guide and fixed to the upper guide at one end thereof in order to guide a window glass so as to move, and a pillar outer panel, made of metal plate, for covering, on an exterior side of a vehicle, a vehicle exterior-end surface of the upper guide, a vehicle exterior-end surface of the window glass guide and an opening formed between the upper guide and the window glass guide.
