A device capable of smoothly, easily and automatically installing a molding on a door panel for an automobile is provided and includes a molding installation jig and a dynamic sensor located between a jig body and an arm. One embodiment has a connecting arrangement between the drive motor and the impeller that permits the two to be easily and quickly coupled and uncoupled. Two separate Y address decoders, one feeding into the column latches and the other into the bit line select circuit, provide column latch and bit line selection respectively. Namely, the present invention can perform an electrical connection check and a hydraulic pressure check in a collective fashion. The light, as shifted, is emitted from the assembly generally along an axis orthogonal to the plane. Upper and lower sides of the bracket have a symmetric shape with respect to a longitudinal direction axis in a state of the bracket being attached to the vehicle body.
