A seal device where a seal lip reliably maintains shaft sealing relative to high-pressure fluid that is to be sealed and where the equivalent Mises stress occurring in the seal lip is reduced to extend the durable term of the seal lip longer. A backup ring has a tapered section continuously extending from a fixation section of the backup ring and also has a forward end section. A rounded surface (E) with a curvature radius (R-1) is formed at least at a boundary where a surface (D) of the tapered section changes to a surface (F) of the forward end section. A portion of the surface (D) of the tapered surface, which portion is in contact with the rounded surface (E) at the boundary, is a projected curvature surface having a curvature radius greater than the curvature radius (R-1) of the boundary.

Seal device

[PROBLEMS] A seal device where a seal lip reliably maintains shaft sealing relative to high-pressure fluid that is to be sealed and where the equivalent Mises stress occurring in the seal lip is reduced to extend the durable term of the seal lip longer. [MEANS FOR SOLVING PROBLEMS] A backup ring () has a tapered section () continuously extending from a fixation section () of the backup ring () and also has a forward end section (). A rounded surface (E) with a curvature radius (R-1) is formed at least at a boundary () where a surface (D) of the tapered section () changes to a surface (F) of the forward end section (). A portion of the surface (D) of the tapered surface (), which portion is in contact with the rounded surface (E) at the boundary (), is a projected curvature surface having a curvature radius greater than the curvature radius (R-1) of the boundary ().

Grip for hand-held saw

Laser beam projector

Tape measure

A holder assembly for a hand-held device, such as a tape measure, includes a main body for holding the hand-held device, and a bracket that can be fixedly secured to the hand-held device. The bracket is accommodated in the groove of the main body when it is slidingly engaged into the groove from the side of a tapered end region. The main body includes a slider that is engageable with an opposite end region of the bracket when the bracket is accommodated in the groove, for preventing withdrawal of the bracket out of the groove of the main body. The slider is manually disengageable from the bracket for allowing the bracket to be removed out of the groove of the main body.

A connector apparatus wherein a connector member includes an insulation material connector body with a large number of contacts projecting downwardly from the connector member base for positioning on a printed circuit base board. An attaching member is provided for attaching the contacts to the printed circuit board. An end portion of each of the contacts is connected by soldering to a printed circuit of the base board. The attaching member includes a metallic plate member provided at its one end portion with a pair of legs including projections positioned at forward ends respectively for engagement with and for soldering to the printed circuit base board. The metallic plate member may be provided on both side edges with a pair of engaging claws which engage an inner wall of an attaching opening made in the connector body. The attaching member may include the metallic plate member and a tap screw which is screwed into a second end portion of the metallic plate member.
