A double-row angular contact ball bearing is provided with inner and outer rings, balls in two rows, a cage for holding the balls, and non-contact sealing devices made of a substantially disc-like member. Radial outer end portions of a metallic sealing device are respectively fit and swaged into grooves arranged at both axial end portions of the outer ring's inner circumferential surface. The ratio Ts/Tr is equal to or lower than 0.07, where Ts is the sealing device thickness and Tr is the outer ring thickness at the bottom portion of the groove. In addition, the ball diameter is equal to or greater than 75% of a half a bearing width to equal to or greater than 83% thereof. Furthermore, an axial width Tc of the radial outer end portion having a substantially U-shape is equal to or smaller than 2.7 mm.

A seat belt buckle is disclosed in which play between a buckle base and a buckle button caused by vibration during the operation of an automobile is prevented, so that the tips of a pair of arm leaves formed on the buckle button are elastically pressed against the outer surfaces of a pair of upright plates on the buckle base to prevent lateral play between the buckle base and the buckle button, while vertical play is prevented by the elastic pressure from the tips of another pair of arm leaves against the upright plates.

Buckle for seat belt

A buckle device with a switch for detecting tongue-lock comprises a base, a latch piece supported on the base so as to move between a tongue-lock position and a tongue-unlock position, a lock plate provided so as to move between an engaged position at which the latch piece remains stationary in the tongue-lock position and a disengaged position which permits movement from the tongue-lock position of the latchpiece, such that the lock plate moves to the engaged position following the movement of the latch piece to the tongue-lock position, a release button for setting the lock plate in the disengaged position; and a switch assembly for detecting whether the lock plate is located in the engaged position or not.

Buckle device with switch for detecting tongue lock

A buckle is constructed of a base, latch piece, holding member and release member. The base has a bottom wall and side walls defining substantially L-shaped holes. The latch piece is supported on the base rockingly between a tongue latching position and a tongue non-latching position. The holding member is received at both end portions in the holes displaceably between a holding position, where the end portions are in the horizontal portions of the corresponding holes so as to hold at the latching position the latch piece which has been in the latching position, and a non-holding position where the end portions are in the vertical portions of the corresponding holes so as to permit movement of the latch piece from the latching position. The release member is provided displaceably between a non-operated position and an operated position and adapted to bring the holding member to the non-holding position and the latch piece to the non-latching position when the release member assumes the operated position.
