A tray () including a bottom wall () and a peripheral side wall () erected from an outer periphery of the bottom wall () includes a high-strength portion HT having a high tensile strength; and a low-strength portion LT having a tensile strength lower than that of the high-strength portion HT. The low-strength portion LT includes a recessed portion (C) having a corner portion (C) in a first side wall inner surface () and a second side wall inner surface () which are adjacent to each other at a minor angle and a corner section (C) on an upper surface () of the bottom wall () having a minor angle to each of the first side wall inner surface () and the second side wall inner surface ().

Tray and tray manufacturing method

A subframe () includes a base member () and a first member (). The base member () is a channel-shaped member that includes a base surface portion () and two wall portions () on both sides of the base surface portion () in a vehicle length direction and is open on its lower side in a vehicle height direction. The first member () includes a bottom wall portion (), a top wall portion (), and a side wall portion (). The bottom wall portion () and the top wall portion () are disposed in the same direction as the base surface portion (). The top wall portion () is overlapped on and joined to the base surface portion (). The wall portions () and the bottom wall portion () form the channel shape. The side wall portion () is a wall that blocks a vehicle width direction between the bottom wall portion () and the top wall portion (). A first lower arm support portion () is formed by the base surface portion () and the bottom wall portion ().

Subframe

An exhaust muffler has an outer cylinder into which an exhaust gas from an engine is introduced and a muffling member made of a foamed ceramic material. The outer cylinder has an inner cylinder through which the exhaust gas passes, a part of the muffling member is supported by an outer wall of the inner cylinder via a holding member. The inner cylinder includes, in an area where the inner cylinder overlaps with the muffling member with respect to axial direction of the inner cylinder, a porous wall portion formed with communication holes communicating an inside and an outside of the inner cylinder. The holding member is arranged at a position where it does not overlap with a part of the porous wall portion, so that muffling effect is enhanced, and the muffling member having a low resistance to impact forces can be supported stably by the inner cylinder.

Exhaust muffler

A press tooling includes a distance member pivotably supported by a holder; and a moving device provided on a first die unit. The holder is provided in a movable manner with respect to a punch in a press direction, and a pad is provided in a movable manner with respect to a die in the press direction. The distance member is pivotable between a home position in which the distance member does not come into contact with the second die and a preventive position in which the distance between the pad and the holder in the press direction is prevented from being equal to or less than a predetermined distance. As the holder moves relative to the punch in the first direction, the moving device causes the distance member to pivot from the home position toward the preventive position.

Press tooling

A hold device is attached to press tooling. The hold device includes a distance member attached to a holder, and a moving device attached to a first die unit. The holder is provided in a movable manner with respect to a punch in a press direction, and a pad is provided in a movable manner with respect to a die in the press direction. The distance member is pivotable between a home position in which the distance member does not come into contact with the second die and a preventive position in which the distance between the pad and the holder in the press direction is prevented from being equal to or less than a predetermined distance. As the holder moves relative to the punch in the first direction, the moving device causes the distance member to pivot from the home position toward the preventive position.
