  • Publication number: 20190170212
    Abstract: A torsional vibration damper having an improved attenuation performance of low frequency vibration. The torsional vibration damper comprises a rotary member rotated by torque, an inertia body rotated relatively on an outer radial side of the rotary member due to torque pulse, and a rolling member coupled to the rotary member and the inertia body. The rotary member includes support sections that are provided on its outer radial side, and by which the rolling member is restricted in a rotating direction of the rotary member and is engaged movably in a radial direction of the rotary member. The inertia body includes: a pair of mass sections respectively projecting toward both sides in an axial direction; and a pair of raceway surfaces on which the rolling member rolls. A center of curvature of each raceway surface is deviated from a rotational center of the rotary member.

  • Patent number: 10289165
    Abstract: An electronic device having two chassis stably attached to each other is provided. The electronic device includes a first chassis having a display and a second chassis detachable from the first chassis. The second chassis includes a support post that protrudes from the attachment surface to which the first chassis is attached and has a claw portion on a tip side. The first chassis includes a post hole into which the support post is inserted and an engaging projection that engages with the claw portion of the support post inserted into the post hole and elastically biased so that the claw portion can be pressed towards the insertion direction to the post hole. The first chassis has an engaging slider having the engaging projection where the engaging projection is elastically biased in a direction of engaging with the claw portion.
