Abstract:
There is provided an end plate ( 1 ) that includes a through hole ( 40 ) that causes a central part ( 14 ) of an outer wall portion ( 10 ) and a central part ( 24 ) of an inner wall portion ( 20 ) to communicate with each other, into which an intruding portion ( 72 ) provided in a wheel-side member ( 70 ) can intrude, a first press-formed portion ( 50 ) formed with a recessed portion ( 52 ) formed by depressing in a peripheral edge ( 42 ) of the through hole ( 40 ) in the inner wall portion ( 20 ). The end plate ( 1 ) further includes a second press-formed portion ( 60 ) arranged in a part of a peripheral edge ( 26 ) on the side of a peripheral end ( 22 ) of the inner wall portion ( 20 ), which is a remnant of a portion where the first press-formed portion ( 50 ) is arranged in the inner wall portion ( 20 ), and formed therein with a protruding portion ( 62 ) by protruding a part of the peripheral edge, and a screw hole ( 64 ) formed by penetrating through the protruding portion ( 62 ) in the second press-formed portion ( 60 ) between the outer wall portion ( 10 ) and the inner wall portion ( 20 ).
Abstract:
A friction stir welding apparatus (1) has a probe (32)that is movable in a vertical direction with respect to a processing-target side surface (W s ) of a processing target member (W) and rotatable relative to the processing target member (W), a welding tool (30) having an interposed member (34) that covers a part of an outer periphery of the probe (32) and is rotatable relative to the probe(32), a mounting member (10)on which the processing target member (W) is mounted, a movement mechanism (50) having an arm (54) fitted with the welding tool (30) that can move the welding tool (30)with respect to the processing target (W) member by moving the arm (54, and a correction mechanism (20) having a correction member (22) that can correct a moving direction of the welding tool (30) so as to be matched with a predetermined processing direction (D), by bringing the interposed member into contact with the processing target member (W) when the welding tool (30) is moved with respect to the processing target member (W) by moving the arm(54), and fixed to the mounting member (10).
Abstract:
In a pedal device (1) that can recede a pedal arm (20) from a passenger side such as a driver reliably and can recede a retainer (30) as a control member for realizing a receding posture of the pedal arm (20) from a vehicle body side reliably at the time of a frontal collision or the like of a vehicle, a first guide hole (13) provided in a pedal bracket (10) attached to the vehicle body includes a leading end hole portion (13a), a terminal end hole portion (13c), and a connecting hole portion (13b) that connects the leading end hole portion (13a) and the terminal end hole portion (13b), and a second guide hole (40) provided in a retainer (30) engaged and attached to the pedal bracket (10) by engaging portions (33,35) includes a first hole portion (40a) and a second hole portion (40b) connected to each other.
Abstract:
Disclosed is a weld joint of an aluminum alloy member formed by joining one end of a wrought material (12) to one end of a cast member (11). The cast member has a chamfer (14), and an inserting portion (13) which extends from the lower end of the chamfer (14) toward the distal end of the case member along the lower surface of the wrought material. The distance (L) from the lower end of the chamfer to the end face (12a) at one end of the wrought material is set equal to 1.0-1.7 times of the thickness (T) of the wrought material, and the chamfer is inclined so that the angle of a groove between the chamfer and the end face (12a) at one end of the wrought material is 15-45°.
Abstract:
A torsion beam suspension in which an opening end surface of a trailing arm rear end is butt-welded to a spindle support plate. A front bent flange (13F) and a rear bent flange (13R) are integrally and continuously provided at the front end of a plate body (13M) of a spindle support plate (13) and the rear end of the plate body (13M), respectively. The front bent flange (13F) is extended forward along a rear end outer surface of a trailing arm (10) and welded (w3) at its front end edge to the rear end outer surface. The rear bent flange (13R) is engaged with and welded (w4) to a rear end edge of the trailing arm (10). A spindle base plate (14b) is superposed on and fixed (w2) to the outer surface of the plate body (13M) and has four screw holes (Sfu, Sfd, Sru, Srd) positioned to the front and right, and above and below a spindle axis, the four screw holes being used for fixing a brake-related plate like part (P) to the spindle base plate (14b) with bolts. The spindle support plate can be reduced in wall thickness while influence of strain caused by welding heat suppressed, and as a result, the spindle plate support is reduced in weight and cost.
Abstract:
An α-pentafluoroethyl acrylic acid derivative represented by the general formula [I]:
[wherein R represents a hydrogen atom, a non-substituted or substituted aromatic ring, or a straight or branched alkyl group having 1 to 20 carbon(s) which may have a cyclic moiety optionally substituted with at least one substituent (halogen atom, hydroxyl group, straight or branched alkoxy group having 1 to 10 carbon(s) which may have a cyclic moiety, non-substituted or substituted aromatic group)].
