    • An object of the present invention is to decrease the machining cost and to improve the productivity. A liquid pressure control device (21) for load responding brake comprises a valve mechanism (25), which is slidably disposed in a housing (22), for decreasing the liquid pressure of a master cylinder in a predetermined proportion and transmitting the liquid pressure to a rear wheel brake cylinder by the movement of a plunger (24) operated in response to the liquid pressure from the master cylinder; and a load sensing mechanism (27) in which a load depending on the movable load of a vehicle is applied to the plunger (24) so as to move the pressure decrease operation start point of the valve mechanism (25). The housing (22) is formed by cutting a long material (50) formed by extrusion or drawing to a predetermined length and then by machining the cut material (51).

    • Disclosed are a butt welding apparatus, a butt welding method, and a product manufactured by the butt welding method. Two electrode rollers (3, 4) are disposed on both the front and back sides of a thick sheet member (1) and on both the front and back sides of a thin sheet member (2) whose end surfaces (1A, 2A) are butted. The electrode rollers (3, 4) are applied with power, melt the butt portion (6) of the sheet members (1, 2) with electric resistance heat, and joint the butt portion. Further, the electrode rollers (3, 4) have a length bridging across the sheet members (1, 2) and are composed of first portions (3A, 4A) arranged as small diameter portions on the side of the thick sheet member (1) and second portions (3B, 4B) arranged as large diameter portions on the side of the thin sheet member (2). The first portions (3A, 4A) come into contact with the thick sheet member (1) and presses it before the second portions (3B, 4B) come into contact with the thin sheet member (2). Thus, the end surface (1A) of the thick sheet member (1) swells and deforms toward the thin sheet member (2) and reliably comes into contact with the end surface (2A) of the thin sheet member (2). As a result, power is applied between the end surfaces (1A, 2A) even if the end surfaces (1A, 2A) are not finished by polishing and the like.

    • The present invention is a butt welding apparatus and a butt welding method where end faces of at least one plate member to be welded are butted to each other to form a butt portion, and butt welding can be performed on respective plate members to be welded which have various thickness sizes on both side portions of the butt portion with electric resistance heat by a pair of two electrode members which are made common to the respective plate members and are supplied with power. At least one electrode member (1) of a pair of electrode members (1, 2) for butt-welding two plate members (31, 32) is provided on an outer face thereof with a retreating-shaped portion (1A) which gradually retreats from one plate member (31) of the two plate members (31, 32) according to extension from an intermediate portion, in a thickness direction, of the one electrode member (1) along the one plate member (31). Butt welding of the two plate members (31, 32) is performed in a state that the position of the butting portion (71) of these plate members (31, 32) has been offset from intermediate portions, in thickness directions, of the electrode members (1, 2) to the retreating-shaped portion (1A) by an amount (L1) corresponding to a difference in thickness between the plate members (31, 32), and butt welding of two other plate members having different thickness sizes is performed with a changed offset amount.
