摘要:
A preform having edges overlapped and jointed, two outer members for forming outer surfaces of a hydroformed product, and reinforcement members for forming reinforcement ribs that divide a hollow cross section of the hydroformed product, including a joint formed by, when more than three sheet materials for forming the outer members and the reinforcement members are overlapped together, welding a first sheet material on a surface of the overlapped sheet materials to a second sheet material positioned inside the first sheet material, and a space disposed and aligned with a joint plane between the second sheet material and a third sheet material located inside the second sheet material during the welding process.

In a connector including a housing to be fitted to a mating connector and a lever rotatable to the housing between a first and a second position, a main body of the lever has a generally flat shape and provided with a recess recessed from a principal surface of the main body in a thickness direction to have a bottom portion. A spring portion extends from the main body in the recess to have a free end and being elastically deformable in the thickness direction. A locking portion is formed to the spring portion at a first portion away from the free end and adapted to be locked with the housing when the lever is at the second position. The spring portion faces the bottom of the recess with a distance greater at a second portion between the free end and the first portion than that at the first portion.

The lever comprises a main plate portion, a supporter portion, and an arm. The main plate portion is laid in parallel with a predetermined plane. The supporter portion extends from the main plate portion. The arm is supported by the supporting portion and is bendable in a predetermined direction. The predetermined direction is not equal to a direction perpendicular to the predetermined plane. The arm is provided with a first engagement portion. The housing comprises an accommodation portion and a second engagement portion. The second engagement portion is formed in the accommodation portion. The housing accommodates and rotatably supports the main plate portion in the accommodation portion so that the lever is provided with rotary movement between a first position and a second position. The lever connector is connected to the mating connector and the first engagement portion is engaged with the second engagement portion upon rotation of the lever from the first position to the second position.

A connector includes an insulator having contact receiving portions and a retainer receiving portion that communicate with each other. The connector further includes conductive contacts inserted into the contact receiving portions from a first direction, respectively. The connector further includes a retainer inserted into the retainer receiving portion from the first direction for preventing the contacts from coming off in a direction opposite to the first direction. The retainer includes a body portion and a pair of elastic pieces each elastically deformable and joined to the body portion. The body portion has a pair of excessive deformation preventing portions each for preventing excessive deformation of the corresponding elastic piece toward the body portion. The elastic pieces each have a specific lock portion, and the insulator has a pair of specific lock receiving portions each for locking the corresponding specific lock portion when the retainer is inserted to a predetermined position of the retainer receiving portion.

A preform with edges overlapped and jointed each other and first and second outer members for forming outer surfaces of a hydroformed product, and reinforcement members that are jointed to the first and second outer members to form reinforcement ribs that divide a hollow cross section of the outer surfaces, the reinforcement members having dimensions capable of suppressing elongation in a tensile direction due to a tensile force that develops during hydroforming.
