A shock absorber () for downhole use comprises an elongate, hollow member defined by a series of mutually aligned, plastically deformable perforated members () having aligned perforations that define the hollowness of the elongate, hollow member that are spaced from one another in the direction of elongation by respective relatively rigid spacer members () that are secured to the perforated members. The elements of each pair of perforated members () of the series are so spaced from one another by one or more of the spacer members () such that on compression of the shock absorber () the perforated members () deform plastically to a lesser extent in regions at which the spacer members () are secured than at other regions. The arrangement of the perforated members () and the spacer members () causes compression to occur substantially parallel to the length of the shock absorber ().
