Patent number: 9024992Abstract: The oscillation element according to the present invention includes a torsion bar mounted on a base, and an oscillating member having a light reflection surface for reflecting light from a light source, which is fixed on the torsion bar protruding from the base. The oscillating member oscillates about a longitudinal axis of the torsion bar with an elastic deformation of the torsion bar, thereby deflecting the light that reflects at the light reflection surface in a direction intersecting the longitudinal axis. The oscillating member has two plates that are joined together so as to sandwich the torsion bar. On joining surfaces of the plates are provided with grooves for receiving the torsion bar, respectively. The plates have a symmetrical shape that the longitudinal axis serves as the axis of symmetry.Type: GrantFiled: January 4, 2012Date of Patent: May 5, 2015Assignee: Canon Denshi Kabushiki KaishaInventors: Takayuki Wakabayashi, Naruki Suzuki, Katsumi Arai, Yaomin Zhou
