<p>A stroke sensor (100) detects a relative position of a piston (2a) with respect to a cylinder (1) of a fluid pressure cylinder (100). The stroke sensor (100) comprises a magnet (4) fixed to the piston (2a) and a sensor probe (3) fixed to the cylinder (1). The sensor probe (3) generates a signal in response to a relative position with respect to the magnet (4). The magnet (4) is gripped between a holder (6) which is fixed to the piston (2c) and a seat member (5) which is supported by the piston (2a). By gripping an elastically deformable shock absorbing member (7) between the magnet (4) and the holder (6), the precision with which the magnet (4) is positioned with respect to the piston (2) is increased while protecting the magnet (4) from damage due to excessive gripping force.</p> |
