Abstract: A degassing apparatus capable of preventing cross-contamination is provided. A degassing apparatus 1 includes degassing modules 10, 20, and 30 each having a tube unit 12 that is a gas permeable membrane separating a fluid circulation space S1 and a reduced-pressure space S2 from each other, vacuum piping 40 communicatively connected to the reduced-pressure spaces S2, a discharge device 50 that discharges gas in the reduced-pressure spaces S2 through the vacuum piping 40, atmospheric release piping 60 communicatively connected to the reduced-pressure spaces S2, an atmospheric release valve 70 capable of introducing atmosphere into the reduced-pressure spaces S2 through the atmospheric release piping 60, and a control unit 80 that controls the operation of the discharge device 50 and the atmospheric release valve 70.

Abstract: A disk brake (1) including a connector portion (35) provided at a housing (30). The connector portion (35) includes supply terminals (131) for supplying power to a motor (32). The supply terminals (131) of the connector portion (35) and motor terminals (32C) of the motor (32) are connected to each other via bus bars (130) made of metallic plate. Further, the bus bars (130) are held in a loosely fitted state on another-side surface (138B) of a plate-like portion (138) of a support member (135) attached to the housing (30).

Abstract: Provided is a disc brake with high reliability. In a disc brake (1), pins (60) press-fitted to a carrier (58) are inserted through hole portions (56B) of respective planet gears (56) in a freely rotatable and axially movable manner. Further, axial movement of the carrier (58) is allowed by an amount corresponding to a length of a clearance (37). As a result, when a rotary-to-linear ramp (65) advances during actuation of a parking brake, the carrier (58) and the pins (60) advance together with the rotary-to-linear ramp (65). Thus, actuation efficiency becomes excellent and durability is enhanced.
