In a reclining device, a pawl is guided by guide walls formed in a guide while both of side portions thereof are applied thereto, so as to be movable only radially inwards and outwards. The pawl is divided into two divisional pawls configured to obliquely contact with each other, so as to be pressed and moved away from each other in opposite lateral directions and to be pressed against the guide walls positioned in respective lateral directions when the pawl is pressed and moved in the advancing direction by the pressing cam. A division line is set to form inclined surfaces that are configured to bring the two divisional pawls into face contact with each other obliquely with respect to the advancing moving direction of the pawl, and vertical surfaces that are configured to bring the two divisional pawls into face contact with each other in a direction perpendicular to the pawl advancing moving direction.

Locking device

An internal combustion engine in an engine exhaust passage of which an NOadsorption catalyst () adsorbing NOcontained in exhaust gas at the time of a low temperature and desorbing the adsorbed NOwhen the temperature rises and an NOstorage catalyst () are arranged. When the NOstorage catalyst () can store NO, the temperature of the NOadsorption catalyst () is made to forcibly rise to a target temperature at which the amount of NOwhich the NOstorage catalyst () can store is desorbed, and the NOdesorbed from the NOadsorption catalyst () is stored in the NOstorage catalyst ().

Exhaust purification device of internal combustion engine

An S storage catalystis equipped with a catalytic supporter, a catalytic metal being supported on this catalytic supporter and oxidizing SOto SO, and an S storage material being supported on the catalytic supporter and storing S components therein. This S storage catalysthas an exhaust-gas-inlet-side high-concentration portionA in which the S storage material is supported on the catalytic supporter in a high concentration, and an exhaust-gas-outlet-side low-concentration portionA in which the S storage material is supported on the catalytic supporter in a low concentration that is lower than that of the high-concentration portion. In accordance with this S storage catalyst, it is possible to maintain the S storing performance favorably, even in a case where exhaust-gas temperatures are low, while keeping the material cost from rising steeply.

S storage catalyst and exhaust-gas converting apparatus

A connector for a vehicle seat includes a ratchet, a guide, and engagement pieces. The engagement pieces are supported so as to be movable only in the radial direction of the guide, and prevent relative rotation between the ratchet and the guide when engaged with an inner peripheral toothed face of the ratchet. The inner peripheral toothed face is formed in the inner peripheral face of an annular wall that extends from the outer peripheral portion of a disc portion of the ratchet in its axial direction. The inner peripheral face is in contact with and supported by outer peripheral faces of guide walls that project in the axial direction from the inner disc face of the guide. Thus, the ratchet and the guide are coaxially fitted together so as to be rotatable relative to each other.

Connector for vehicle seat

A storage catalystis constituted of a supporter substrate, which is formed of at least one member being selected from the group consisting of AlO, CeO, ZrO, TiOand zeolite, and whose specific surface area is 30 m/g or more, and a coating layer, which includes a supporting powder including at least one member being selected from the group consisting of AlO, CeO, ZrO, TiOand zeolite, a storage material for storing NOand SO, the storage material being supported on the supporting powder, and a noble metal being supported on the supporting powder. Since the supporter substratehas a large specific surface area, a supporting amount of the storage material for storing NOand SOaugments remarkably. Therefore, an SOstorage amount of the storage catalyst, which is put in place on an upstream side of an NOstorage-and-reduction catalyst, augments, and thereby an NOstorage amount in low-temperature regions augments.

Exhaust-gas converting apparatus

A noble metal is supported on an upstream-side catalytic portionat least, and an SOstorage material, such as Mg and K that lower the noble metal's activities, is supported on a downstream-side catalytic portion. The noble metal being supported on the upstream-side catalytic portionoxidizes SOefficiently to turn it into SO, because the lowering of oxidizing activities is suppressed. These SOare retained by means of storage in the SOstorage material being loaded on the downstream-side catalytic portion. Therefore, the SOstoring performance improves, and it is good in terms of durability as well.

Sulfur storage catalyst

A connecting device may include first and second connecting elements that are axially oppositely coupled to each other so as to be rotatable relative to each other, a locking member that is positioned between the first and second connecting elements, an operating member that is positioned between the first and second connecting elements, and a retainer member that is arranged and constructed to circumferentially clamp the first and second connecting elements. The retainer member has a retainer portion and is fixed to the first connecting element while the second connecting element is axially supported by the retainer portion of the retainer member.

Connection devices in vehicle seats

A connecting apparatus for rotatably connecting two object members of a vehicle seat relative to each other. The connecting apparatus may include first and second connecting members, a lock member and an operating member. The first and second connecting members are integrated to be able to rotate relative to each other. The lock member is able to lock the relative rotation between the connecting members by meshing outer peripheral teeth with inner peripheral teeth formed at the second connecting member. The operating member moves the lock member between a mesh state and a release state.

Connecting apparatuses for vehicular seats

Seat reclining mechanisms for a vehicle seat may include a first or stationary housing, a second or rotational housing, a locking means received between the first and second housings, and a fastener for rotatably connecting the second housing to the first housing. The fastener is formed with at least one retainer portion and at least one slide portion that respectively project toward the second housing. Preferably, the at least one slide portion has a height greater than the at least one retainer portion.
