Abstract: Disclosed is a method of suppressing vibration of a mechanical device imposing upon at least one human hand holding the mechanical device. The method generally includes steps of preparing and assembling a fixing pin, an upper metal pad, an upper suppressing pad, a lower suppressing pad, and a lower metal pad to form a vibration-suppressing unit, and employing a fixing rack in collocation with an actuating part to fix the vibration-suppressing unit onto a massage body. In particular, the two adjacent upper vibration-suppressing washers are specifically designed to have different elasticity modulus, and the two spaced away and not adjacent upper vibration-suppressing washers have the same elasticity modulus, thereby suppressing and alleviating the vibration level to hand due to counterforce. Thus, the method achieves the effect of suppressing vibration, greatly alleviates counterforce imposing upon hand, and effectively avoiding fatigue, sore, chronical inflammation, or physical hurt.

Abstract: It is possible to prevent occurrence of a resonance phenomenon of a hydraulic unit and to improve attachability/detachability of the hydraulic unit to/from a bracket.
A support section (42, 43) includes: a fixture member (80) that is fixed to a housing (30) for a hydraulic unit (10); and a vibration absorbing member (75) that is interposed between the housing (30) and a bracket (41) and has a through-hole (75a) through which the fixture member (80) passes. The vibration absorbing member (75) includes two vibration absorbing members (75B, 75C, 75D) having different rebound resilience from each other. In a state where the vibration absorbing member (75) is partially accommodated in a recessed section (47) of the bracket (41), the vibration absorbing member (75) is held between the housing (30) and the bracket (41).

Abstract: A dampener for an exit device may be disposed between a portion of an exit device actuator and an exit device chassis so that the dampener dampens vibrations to reduce noise of the exit device and/or inhibit unintentional movement of the actuator to an actuated position. The dampener may be composed at least partially of a viscoelastic material.

Abstract: Provided is a treadmill. The treadmill includes a shock absorbing portion configured to absorb a shock applied to a deck. The shock absorbing portion includes a second anti-vibration rubber portion having a third surface fixed to a frame and a fourth surface fixed to the deck. The third and fourth surfaces are perpendicular to a plate surface direction of the deck. The second anti-vibration rubber portion includes a first anti-vibration sub-rubber having the third surface, a second anti-vibration sub-rubber having the fourth surface, and a plate located between the first anti-vibration sub-rubber and the second anti-vibration sub-rubber. The plate located between the first anti-vibration sub-rubber and the second anti-vibration sub-rubber has a greater hardness than the first and second anti-vibration sub-rubbers.
