An antivibration unit attachment structure according to the present aspect includes: a vibration absorption part having a first elastic member which is elastically deformable in a first direction and which is connected to a vibration generation part; and a second elastic member which supports the vibration absorption part and which is connected to a vibration reception part. The second elastic member includes a movable part that extends from the vibration absorption part to both sides in a second direction and that is supported by the vibration reception part. The second elastic member is elastically deformable in the first direction and has an elastic coefficient different from that of the first elastic member. The vibration reception part includes a regulation member that comes into contact with at least one of the vibration absorption part and the second elastic member and that limits displacement of the second elastic member to the first direction.

A transmission-side mount bracket includes connection portions which connect a front-side leg portion and a rear-side leg portion of a leg member, a middle attachment (fixation) portion which is provided at the connection portions at a position located between the front-side leg portion and the rear-side leg portion and fixed to the powertrain, and a rigidity-reduction portion (an opening portion) which has the rigidity against a load applied in the vehicle width direction which is lower than that of the front-side leg portion and the rear-side leg portion and is provided at a position located in the vicinity of the middle attachment (fixation) portion.

A power train support structure includes a first front side frame disposed on one of left and right sides of a power train; a second front side frame disposed on the other of the left and right sides of the power train, and being greatly away from the power train with respect to the first front side frame; a mounting bracket having one of left and right ends connected to the power train; and a connecting member for connecting the mounting bracket and the second front side frame. The mounting bracket includes a front fixing portion and a rear fixing portion to be fixed to the power train. A strength of the front fixing portion and the rear fixing portion is set to such a strength that the rear fixing portion is broken by a collision load from a front side, and the front fixing portion is not broken.

A fastening system for fastening a drive unit to a vehicle body includes at least three vibration-damping elements and at least one additional spring element and/or damping element for mounting the drive unit arranged on the vehicle body. The additional spring element and/or damping element is arranged between the drive unit and the vehicle body such that the main effective direction of the additional spring element and/or damping element extends substantially in the vehicle longitudinal direction.

A sub-roll rod device for mounting a powertrain of a vehicle can, in addition to mounting the powertrain in an engine room of the vehicle using a mounting member in a three-point supporting method, mount the sub-roll rod that can be assembled with the powertrain in a side member of a vehicle body, thus controlling forward-and-backward movement of the powertrain while maintaining Noise, Vibration & Harshness (NVH) performance by the three-point supporting method and improving ease of assembly of the powertrain with respect to the engine room.

A anti-vibration device (1) includes a bracket (4) made of a synthetic resin and cylindrical metal fittings for fastening (5), where the bracket (4) and the metal fittings for fastening (5) are integrally formed. A vibration input position (P) is a position that does not coincide with a virtual line (L1) passing through central axes (O5) of a through holes (5h) of two metal fittings for fastening (5) in a planar view; the metal fitting for fastening (5) has a flange portion (51); and the flange portion 51 has a first outermost peripheral edge (51a) and a second outermost peripheral edge (51b), where a length (L51a) to the first outermost peripheral edge (51a) is longer than a length (L51b) to the second outermost peripheral edge (51b) based on the center axis (O5) of the through hole (5h).

A variable stiffness vibration damping device includes a first support member, a second support member, a main elastic member, a diaphragm, a partition elastic member, a first communication passage, a coil, a yoke, and a magnetic fluid. The first communication passage is provided in one of the first support member and the second support member such that a first liquid chamber and a second liquid chamber communicate with each other via the first communication passage. The first communication passage includes a first circumferential passage. The coil is wound coaxially with the one of the first support member and the second support member. The yoke is included in the one of the first support member and the second support member and forms a first magnetic gap overlapping at least partially with the first circumferential passage.

A power generator management system comprises a plurality of power generators, and an information processing apparatus configured to process information acquired from the plurality of power generators. Each power generator comprises: a detection unit configured to detect a remaining fuel amount in a fuel tank of the power generator; a position acquisition unit configured to acquire position information of the power generator; a state acquisition unit configured to acquire information representing an operating state of the power generator; and a communication unit configured to transmit the remaining fuel amount, the position information, and information representing the operating state to the information processing apparatus, and the information processing apparatus comprises a processing unit configured to acquire a margin level of power supply in each of the plurality of power generators and provide a result of the acquisition.

A vehicle front portion structure includes a motor, a stabilizer having an extending portion disposed at a vehicle front side of the motor and that extends further in a vehicle width direction than a length of the motor, and having an arm portion that extends toward a vehicle rear side from each end of the extending portion, a plurality of motor fixing portions, a part of the motor fixing portions being disposed at respective outer sides in the vehicle width direction relative to the motor and at a position between the motor and the extending portion, and a plurality of stabilizer support portions that support respective end parts of the extending portion, the stabilizer support portions being disposed further toward a front side than the motor fixing portions, and at least a part of the stabilizer support portions being aligned with the motor fixing portions in the vehicle front-rear direction.
