Abstract
An acceleration detecting device is provided with a mass body (1) having a through hole (1a) and a sliding shaft (2) passing through the through hole (1a) and sliding the mass body (1) and is constituted such that the slicing shaft (2) comes in contact with the through hole (1a) at two points (3a) and (3b) to support the mass body (1). When the through hole (1a) is circular in cross section, the cross section of the sliding shaft (2) is formed in the shape of an ellipse elongated in the lateral direction or in the shape of an oblong circle elongated in the lateral direction.
Claims10
An acceleration detecting device comprising:
- a mass body having a predetermined mass and a through hole made through the mass body;
- and
- a sliding shaft passing through the through hole and sliding the mass body,
- wherein the sliding shaft comes in contact with the through hole at only two points to support the mass body.
An acceleration detecting device comprising:
- a mass body having a predetermined mass and a through hole made through the mass body;
- and
- a sliding shaft passing through the through hole and sliding the mass body,
- wherein the sliding shaft comes in contact with the through hole at two or more points to support the mass body,
- wherein when the through vole is circular in cross section, the sliding shaft is formed in such a shape that the sliding shaft tomes in contact with the through hole at two or more points to support the mass body,
- wherein the sliding shaft has a cross section formed in the shape of an oblong circle elongated in the lateral direction.
An acceleration detecting device comprising:
- a mass body having a predetermined mass and a through hole made through the mass body;
- and
- a sliding shaft passing through the through hole and sliding the mass body,
- wherein the sliding shaft comes in contact with the through hole at two or more points to support the mass body,
- wherein when the through hole is circular in cross section, the sliding shaft is formed in such a shape that the sliding shaft homes in contact with the through hole at two or more points to support the mass body,
- wherein the sliding shaft has a projection for regulating the rotation of the mass body.
