    Abstract: The present invention provides a two-component type urethane-based adhesive composition for an automobile, which has a good productivity because of high curing rate, which there is not much change between physical properties of a cured product formed from a first component alone and those of a cured product formed from a mixture of first and second components, and which it is possible to satisfy required performances for an automotive adhesive without the second component. The present invention relates to a two-component type urethane-based adhesive composition for an automobile comprising (1) a first component comprising an isocyanate group-terminated polyether polyol compound, and (2) a second component comprising a polyol compound and curing catalyst, wherein a cured product from the first component alone has an elastic modulus of 5 to 20 MPa and an elongation of 300 to 850%, and wherein a cured product from a mixture of the first and second components at a mixing ratio of the first component to the second component of 100/10 has an elastic modulus of 3 to 20 MPa and an elongation of 300 to 650%.

    Abstract: A rotation transmission disc includes: an outer circumferential portion on which a load acts when rotation is transmitted; a center opening portion formed inside the outer circumferential portion; and a plurality of attachment holes for attachment of the rotation transmission disc 1 to a rotating element. A first crosspiece portions are formed in each of ranges of divided angles formed by two adjacent attachment holes with respect to a center of the rotation transmission disc. The first crosspiece portion extends from a load point, which is an intersection between a straight line extending in a radial direction to internally divide the divided angles at a predetermined angular ratio and a load radius position of the outer circumferential portion, to one of the attachment holes forming the divided angles. The second crosspiece portion extends from the load point to the other attachment hole of the attachment holes forming the divided angles.

    Abstract: A dispenser used for discharging a mixture of gas and a paste material includes: a nozzle part provided in a tip end part of a body and having a tip end opening through which the mixture is discharged; a flow path extending from a mixture introduction part to the tip end opening through a hollow space of the nozzle part; a needle part movable in the flow path of the nozzle part to open and close the flow path; a driving part that drives the needle part; and a stopper part that limits an operation range of the needle part. The nozzle part has a tapered section in which an inside diameter of the flow path of the nozzle part decreases toward the tip end opening. Also provided is a stopper position adjusting part that adjusts a stop position defined by the stopper part.
