Abstract: A film roll replacement device supplies a film roll to a bag making and packaging machine. The film roll replacement device includes a holding section, a driving unit, and a controller. The holding section is at least temporarily located adjacent to a supporting shaft to support the film roll in the bag making and packaging machine, and the holding section holds a first film roll supplied to the bag making and packaging machine. The driving unit moves the holding section in an up-down direction. The controller controls an action of the driving unit to move the holding section to a position where a height position of a center of the first film roll held by the holding section is aligned with the height of a center of the supporting shaft of the bag making and packaging machine.

Abstract: A vehicle damper mount unit includes a first vibration transmission channel through which a vibration inputted from a wheel through a suspension mechanism is transmitted to a vehicle body via a damper rod and a mount rubber mechanism including a mount rubber; and a second vibration transmission channel through which the vibration inputted from a wheel through the suspension mechanism is transmitted to the vehicle body via a damper spring. The first vibration transmission channel has a metallic elastic member configured to restrict an upper limit of a stroke of the damper rod caused by the vibration transmitted. The elastic member and the mount rubber are arranged in series on the first vibration transmission channel. The vehicle damper mount unit elastically connects to an upper end of the damper rod fixed to the vehicle body and elastically supports the damper spring arranged outside the damper constituting the suspension mechanism.

Abstract: A bush for a vehicle includes: an inner cylindrical member; a substantially cylindrical rubber member provided outside the inner cylindrical member; and a substantially cylindrical metal spring member inserted between the inner cylindrical member and the rubber member. A gap portion for allowing the metal spring member to be elastically deformed in a radial direction of the metal spring member is provided between the inner cylindrical member and the metal spring member. The bush for a vehicle works such that when impact force belonging to a relatively low vibration frequency area or impact force resultantly accompanied with great displacement is inputted into the bush for a vehicle, mainly the rubber member absorbs vibrations; and when impact force belonging to a relatively high vibration frequency area is inputted into the bush for a vehicle, mainly the metal spring member absorbs vibrations.
