Abstract
An acceleration sensor comprises a first sensor unit, and a second sensor unit. The first and second sensor units can be selectively assembled in a first manner that the first sensor unit is inserted from one side thereof into the second sensor unit, wherein the former is directed in a first direction with respect to the latter, and in a second manner that the first sensor unit is inserted from a side opposite to the one side thereof into the second sensor unit, wherein the former is directed in a second direction opposite to the first direction with respect to the latter. The first sensor unit assembled with the second sensor unit in the first manner is symmetrical with the first sensor unit assembled with the second sensor unit in the second manner with respect to the second sensor unit. A safety belt retractor incorporates an acceleration sensor constructed as above. The second sensor unit may be two types, one of which can be assembled with the first sensor unit only in the first manner, and the other only in the second manner.
