An antivibration device is equipped with an inner sleeve having a diameter expansion portion, an outer sleeve, an antivibration base body, and an annular stopper. The stopper is equipped with a first portion where a first distance from the center of the attaching hole to an inner peripheral surface of the attaching hole is set to be smaller than a maximum value of an outer radius of the diameter expansion portion, and a second portion where a second distance from the center to the inner peripheral surface of the attaching hole is set to be larger than the first distance.

A vibration-damping device (1) of the present invention includes a tubular first attachment member (11), a second attachment member (12) that is attached to any one of a vibration generating portion and a vibration receiving portion, an elastic body (13) that connects the first attachment member and the second attachment member with each other, and a bracket (B) that is connected to the remaining one of the vibration generating portion and the vibration receiving portion and is press-fitted into the first attachment member. The second attachment member includes a stopper wall portion (14) which surrounds the first attachment member from radially outside. A penetration hole (11b) which is open toward the stopper wall portion is formed in the first attachment member, and a stopper elastic body (19) covering the penetration hole is installed on an inner circumferential surface of the first attachment member. The stopper elastic body is elastically deformed by the bracket and protrudes to an outer circumferential surface side of the first attachment member through the penetration hole.

A sheet-shaped cushioning rubber including a planar base portion and a three-dimensional portion formed to rise from the base portion toward one side in a sheet thickness direction, the planar base portion and the three-dimensional portion being alternately provided in one direction of a sheet plane, wherein the three-dimensional portion includes a hollow portion that opens toward the other side in the sheet thickness direction. The three-dimensional portion is integrally provided with a first rising surface that is continuous from the base portion, a top surface, a second rising surface on a side opposite to the first rising surface, and a pair of rising surfaces on both sides in a sheet width direction, and the hollow portion opens only toward the other side in the sheet thickness direction.

A vibration damper for a motor vehicle may comprise a damper outer tube, a damper inner tube having a lateral surface of the damper inner tube and arranged coaxially in the damper outer tube, a separating plate arranged coaxially in a region of the lateral surface of the damper inner tube, and a sealing element arranged coaxially circumferentially on the damper inner tube on the separating plate. In a region of the separating plate arranged coaxially on the lateral surface of the damper inner tube, a groove for the separating plate may be formed on the lateral surface of the damper inner tube. The separating plate may be arranged in the groove, and the connection between the groove and the separating plate may be press fit, at least in the radial direction.

Disclosed is a panel that is produced by assembling a plurality of adjacent individual absorption blocks; each block in the panel is in the shape of a polyhedral pyramid frustum, of which the base is a regular six-sided polygon; each individual block including six lateral walls surrounded by a lower peripheral lip of which each section is provided with a complementary tenon or a mortise arranged so as to allow two adjacent individual blocks to be assembled, in particular by engagement, in the vertical direction, of a tenon and a mortise belonging respectively to one and the other of the two adjacent individual blocks.

Provided is a cylinder device whereby it is possible to easily change and distinguish (identify) damping force characteristics. This cylinder device is equipped with: an inner cylinder in which a function fluid, which is changed in fluid properties by an electrical field or a magnetic field, is sealed, and into which a rod is inserted; a cylindrical member which is provided outside of the inner cylinder, and serves as an electrode or a magnetic pole; and a flow path forming member which is provided between the inner cylinder and the cylindrical member, and forms one or more flow paths through which the functional fluid flows from one end to the other end in the axial direction of the cylinder device in response to the forward and backward movement of the rod. The flow paths are spiral or meander flow paths having circumferentially-extending portions. The flow path forming member is formed with notches which cause axially adjacent portions among the flow paths to communicate with each other.

A sheet-shaped cushioning rubber including a planar base portion and a three-dimensional portion formed to rise from the base portion toward one side in a sheet thickness direction, the planar base portion and the three-dimensional portion being alternately provided in one direction of a sheet plane, wherein the three-dimensional portion includes a hollow portion that opens toward the other side in the sheet thickness direction. The three-dimensional portion is integrally provided with a first rising surface that is continuous from the base portion, a top surface, a second rising surface on a side opposite to the first rising surface, and a pair of rising surfaces on both sides in a sheet width direction, and the hollow portion opens only toward the other side in the sheet thickness direction.

A motor holder, a motor assembly, and an electric toothbrush. The motor holder is configured to be arranged on a motor module, and the motor holder includes a first surface facing the motor module; a rigid body, being a hard rubber part; and a vibration damping structure, being a soft rubber part. The vibration damping structure and the rigid body are in a one-piece structure; the vibration damping structure includes a bonding portion and a plurality of vibration damping protrusions arranged on the bonding portion; the bonding portion is connected to the rigid body, the plurality of vibration damping protrusions are arranged at intervals, and the plurality of vibration damping protrusions protrude from the first surface.
