a fixed member received in said stepped accommodating chamber of said air valve casing, said fixed member having an underside formed with a recessed groove, said fixed member having a topside bored with an insert hole passing through said recessed groove, said fixed member provided with an air intake accommodating with said recessed groove, said fixed member having an outer wall provided with male threads to be threadably locked with said female threads in said stepped accommodating chamber of said air valve casing;
a cap assembled on said air valve casing, said cap made of transparent material, said cap having an upper portion formed into a transparent viewing window, said cap formed with an accommodating chamber in an interior, said accommodating chamber having an inner wall provided with female threads to be threadably locked with said male threads of said air valve casing, said accommodating chamber installed therein with an upper indicating member, a third spring and a lower indicating member, said upper indicating member formed with a recessed groove for receiving said third spring therein, said third spring having an upper end resisting against an inner side of said recessed groove, said upper indicating member having an upper portion of an outer wall formed into a low pressure region, said upper indicating member having a lower portion of an outer wall formed into a warning region, said lower indicating member mounted on outer side of said upper indicating member, said lower indicating member provided with a recessed hollow for receiving both said upper indicating member and said third spring therein, said third spring having a lower end resisting an inner side of said recessed hollow, said lower indicating member having an upper edge provided with a flange, said lower indicating member having an outer wall formed into a safety region, said lower indicating member having an underside pushing against said push block of said center post; and
a locking ring installed in said accommodating chamber of said cap, said locking ring bored with a through hole for said lower indicating member to be inserted therethrough, said locking ring provided with male threads to be threadably locked with said female threads of said cap.
2. A tire air valve having the function of indicating tire pressure as claimed in claim 1, wherein said lower locking block has an outer wall provided with an engage recess having a buffer washer fitted thereon.
3. A tire air valve having the function of indicating tire pressure as claimed in claim 1, wherein said low pressure region of said upper indicating member is marked with yellow color, said warning region marked with red color and said safety region marked with green color.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A suspension board with circuit comprising a metal supporting layer, an insulating base layer formed on the metal supporting layer, a conductor layer formed on the insulating base layer, an insulating cover layer formed on the conductor layer, and
a connection terminal portion comprising:
a first opening formed in the metal support layer and provided on a first side of the conductor layer;
a second opening formed in the insulating base layer and provided on the first side of the conductor layer, the second opening corresponding in location to the first opening;
a third opening formed in the insulating cover layer and provided on a second side of the conductor layer, the third opening corresponding in location to the second opening;
and
a flying lead portion comprising:
a conductor line that is formed from the conductor layer in an area that is exposed by the first opening, the second opening and the third opening, and
a reinforcing structure that is formed from at least one of the insulating base layer and the insulating cover layer, the reinforcing structure being provided in a longitudinal direction along the conductor line and not in a lateral direction between adjacent conductor lines for reinforcing the conductor line.
2. The suspension board with circuit according to claim 1, wherein the reinforcing portion is embedded in the conductor line.
3. The suspension board with circuit according to claim 1, wherein the reinforcing portion is formed continuously from the insulating base layer in the flying lead portion.
