摘要： A driving device with a long stroke and high speed driving ability. The device includes a base with a pair of parallel guides which are elastically installed thereon, and includes a drive unit in which there are arranged in series a driving member frictionally engaging the guides, a piezoelectric element for actuating the driving member in a direction in which the piezoelectric element expands and contracts, and a movable member, with a mass larger than the driving member, on which the driving member and the piezoelectric element are installed movably in the direction. When the piezoelectric element expands slowly with a pulse voltage applied thereto, the movable member moves with the driving member remaining stationary, relative to the guide. When the piezoelectric element contracts rapidly, the driving member slides relative to the guide with the movable member remaining stationary relative thereto. Thus, the drive unit is driven and moved along the guide.

摘要： A distributor cap for use in an internal combustion engine includes the ignition cable 5 having at one end thereof a terminal member 9. A bonding member 10 is molded from a hot-melt adhesive resin such as to bury both the terminal member and a portion of the ignition cable in the vicinity of the one end. A connecting member 11 is integrally secured to the bonding member, the connecting member being molded from a resin having the same quality as that of the resin employed to form the distributor cap. The connecting member is adapted to receive a longitudinally intermediate portion of the terminal member such that a distal end portion 9" of the terminal member is exposed to the outside. A tower portion 4 of the distributor cap is formed with a recess 15 which receives the connecting member. Further, the connecting member is fitted into the recess and is integrally welded to the tower portion.
