Abstract: Forming a caulking portion involves forming: a planar portion that is connected to a main body of an iron core piece, that is formed into a concave shape with respect to a face of the iron core piece which is on one side in the thickness direction, that formed into a convex shape with respect to a face of the iron core piece which is on another side in the thickness direction, and that is parallel to the faces; and a pair of extended portions that include a pair of sloped portions which extend out obliquely from both ends, along the lengthwise direction of the caulking portion, of the planar portion, toward mutually opposite sides in the lengthwise direction and toward another side in the thickness direction. Forming the pair of sloped portions involves extending the pair of sloped portions in the oblique directions.

Abstract: A head driving device includes a head supporting portion supporting a head member, a first beam, a second beam, a first piezoelectric unit including a pair of piezoelectric elements, and a second piezoelectric unit including a pair of piezoelectric elements. When voltage is applied to the piezoelectric elements of the first piezoelectric unit, the piezoelectric elements deform, and a distal end of the first beam moves. The piezoelectric elements of the second piezoelectric unit also deform by application of voltage, and moves a distal end of the second beam in a same direction as the distal end of the first beam.

Abstract: A fuel lid opener-has: a heart cam mechanism that is structured so as to, each time a lifter is push-operated via a fuel lid, cause the lifter to alternately repeat advancing-out and withdrawing, and so as to push the fuel lid open due to advancing-out of the lifter; and a locking mechanism-that can restrict operation of the heart cam mechanism. At the locking mechanism, a time when a stopper is moved by operation of a motor, and the aforementioned restricting is released, the aforementioned stopper engages with the heart cam mechanism and operates the heart cam mechanism. Due thereto, the lifter advances-out, and the fuel lid is pushed open.

Abstract: When a fuel lid goes from an open state to a closed state and a pressed state and then returns to the closed state, a contact/non-contact switching mechanism switches a signal outputted from a microswitch from an ON signal to an OFF signal by performing a first operation. When the fuel lid goes from the closed state to the pressed state and then returns to the closed state, the contact/non-contact switching mechanism switches the signal outputted from the microswitch from the OFF signal to the ON signal and the OFF signal in that order by performing a second operation. Under a condition at least of the signal outputted from the microswitch switching from the OFF signal to the ON signal and the OFF signal in that order within a prescribed time, a control unit controls a lifter to rotate to another side around an axis line.
