Abstract: A disk brake capable of improving work efficiency when a friction pad is attached to a mount member. Ear portions of a friction pad are inserted in pad guides of a mount member. A side push spring, which pushes the friction pad in a rotational direction of the disk, is provided at the friction pad. A pad spring is disposed between the mount member and the friction pad. The pad spring includes a guide plate portion and a guide protruding portion. The guide plate portion is attached so as to be able to abut against the pad guide of the mount member, and functions to guide the friction pad in an axial direction of the disk. The guide protruding portion extends from an outer-side portion of this guide plate portion toward an outer side in the disk axial direction. The guide protruding portion is inclined in the disk rotational direction.

Abstract: A heat exchange element of a plate type heat exchanger consists of a plurality of heat transmission plates having an equivalent shape. Each heat transmission plate is formed with flanged through-holes and openings so that each flanged through-hole and each opening are alternately located and separate from each other by a predetermined peripheral distance along a circle of the heat transmission plate. The heat transmission plates are disposed one upon another and sealingly secured to each other in such a manner that one of adjacent heat transmission plates is shifted the predetermined peripheral distance along the circle relative to the other heat transmission plate, thereby enabling to produce the heat exchanger heat exchange element by using only the heat transmission plates of the equivalent shape.

Abstract: A plate type heat exchanger consists of a plurality of heat transmission plates which are piled up and secured to each other. Side wall members are interposed between the adjacent heat transmission plates, so that multiple stages of spaces are formed in the heat exchanger. Additionally, separator wall members are interposed between the adjacent heat transmission plates in such a manner that two fluid paths are defined in alternate stages of the spaces. The side wall members and the separator members are formed of rod material, thereby rendering the heat exchanger light in weight while lowering the production cost of the heat exchanger.
