  • Patent number: 9186827
    Abstract: In a method for molding a resin piston by charging a preheated resin tablet into a cavity of a molding die, and by carrying out compression molding while heating, at a time point when an internal pressure of the cavity arrives at a determined pressure, by pressurizing a pressurizing margin in the molding die, resin which overflows from the molding die is discharged from a passage which is defined in an area except an outer circumferential surface of the piston, while the internal pressure of the cavity is maintained. After a thermosetting cycle has finished, the molding die 21 is opened.

  • Patent number: 9140322
    Abstract: A disc brake pad assembly includes a pair of locking bent portions formed at circumferential end portions of an inner shim plate by being bent towards an opposite side to a pressure plate. Locking through holes are formed individually at base end portions of the locking bent portions. A pair of locking projecting pieces are individually formed so as to project circumferentially from an outer main body portion included in an outer shim plate. A distance between distal edges of the locking projecting pieces is larger than a space between the locking bent portions, and a circumferential length defined between radial side portions of the locking projecting pieces is shorter than the space. The inner main body portion and the outer main body portion are superposed on each other in a state that the locking projecting pieces are brought into engagement with the locking through holes.
