A floating connector has a stationary housing, a movable housing, and a reinforcing member. The reinforcing member is made of a metal plate and is provided with a first plate portion and a second plate portion. The first plate portion is embedded in a guide portion of the stationary housing so as to extend in a depth direction. The second plate portion is embedded in the guide portion so as to extend inward in a width direction from one end in the depth direction of the first plate portion.

A connector according to the present invention comprises a housing and a plurality of contacts. The housing includes a mating portion having a plate shape. The mating portion projects forward and has an upper surface and a bottom surface. The plurality of contacts is held by the housing. Each of the contacts comprises a contact portion, an end portion and a flat portion. The contact portion extends in a connection direction and is exposed at the upper surface of the mating portion. The end portion is embedded in the mating portion. The flat portion forms a boundary between the contact portion and the end portion and does not projects from the upper surface. The flat portion is able to be viewed from above the upper surface of the mating portion.

A suction surface member is provided on an electronic component module including an electronic component base plate and surface mount device mounted on the electronic component base plate in order to provide a suction surface at a location that is substantially at the same level as or higher than that of an upper end of a transistor that is the tallest surface mount device. The suction head adheres to the suction surface to hold the electronic component module and the electronic component module is mounted on a motherboard defining the target board. Then a treatment is performed to prevent a situation in which an upper end of the suction surface member is higher than the upper end of the tallest surface mount device mounted on the electronic component base plate.

A contact capable of facilitating adjustment of impedance and ensuring a high holding force when held in a housing. To a contact portion capable of being brought into contact with a pad on a module substrate, a spring portion is connected for pressing the contact portion against the pad. A press-fitting portion that is press-fitted into the housing is connected to the spring portion, and has a connecting portion connected thereto. A terminal portion to be connected to a pad on a motherboard is connected to the connecting portion. The spring portion is bent in a manner folded back from the rear end of the press-fitting portion in the inserting direction, toward a front side in the inserting direction. The connecting portion extends from the rear end of the press-fitting portion in the inserting direction, toward a rear side in the inserting direction.

The present invention provides a size restoring device for restoring the original size of collars, front plackets, and shirt cuffs using a relatively simple structure to achieve an effective and exact restoration. Also, the present invention provides a size restoring device having holders on a baseboard. The holders hold both ends of the fabric of a shirt's collar. The holders comprise a stretcher, which stretches the fabric by moving at least one of the holders in the stretching direction, and a stretch adjuster for adjusting the distance that the holder has moved to obtain the required measurements. The present invention restores the original size of collars, front plackets, and shirt cuffs which have shrunk after being washed or the like by stretching the fabric to the original size.
