PROBLEM TO BE SOLVED: To fix a center yoke to a back yoke, forming a magnetic circuit together, so as not to be detached from the back yoke due to impact or the like, without increasing the number of parts. SOLUTION: A bottom surface part 421 and a ceiling part 422 constituting a head lift 42A respectively have a lower rib 421a and an upper rib 422a made of a nonmagnetic material for positioning a pair of center yokes 62 constituting a magnetic circuit 60. Instead, an upper flange 48 for attaching the upper place spring 322 of a head holder 32 to the ceiling part 422, and a lower flange 49 for attaching a pair of lower plate springs 322 to the bottom surface part 421 may have respectively an upper arm 481 and a lower arm 491 for pressing the pair of center yokes 62.
