Abstract: According to one aspect of the present invention, a dental filling material is manufactured by surface-treating an inorganic filling material with a silane coupling agent having an epoxy group and then by causing a ring-opening reaction with a composition containing an epoxide having a (meth)acryloyl group.

Abstract: One embodiment of the present invention relates to a dental composition including a (meth)acrylate, an ultraviolet absorber, and a fluorescent agent, wherein the ultraviolet absorber has free of a maximum absorption wavelength in a range of greater than 320 nm and less than or equal to 500 nm.

Abstract: A vehicle door mirror includes a base member mounted on a side door while having plural mounting holes and plural insertion holes coaxially communicating with the mounting holes, and a mirror housing pivotably supported on a support shaft which has a plurality of bosses, each boss having a tubular portion and ribs extending along an axial direction of the tubular portion. Screw members are inserted through respective ones of the insertion holes and screwed into the tubular portions of the bosses respectively inserted into the mounting holes so that the ribs of each boss abut against an inner peripheral face of the corresponding mounting hole. The ribs are projectingly provided on the outer peripheral face, at least on a base part side, of the corresponding tubular portion. Such arrangement suppresses vibration of the mirror even when the support shaft is made of a synthetic resin.

Abstract: A vehicle door mirror in which a pivoting member fixedly housed within a mirror housing on which a mirror is mounted is pivotably supported on a support shaft implanted in a base member mounted on a side door, wherein in order to restrict an end of pivoting of at least one of a forward inclined position and a rearward inclined position of the mirror housing, a restricting face is formed on one of the support shaft and the base member, and a restricting part is provided on the pivoting member, the restricting part being capable of making line contact with the restricting face in one plane orthogonal to an axis of the support shaft. This prevents excessive stress from occurring when restricting the range of pivoting of a mirror housing.
