PURPOSE:To facilitate the prevention of the circumferential displacement between an inner rod and an outer cylinder by providing circumferential displacement preventive means between inner and outer shafts, and storing tapered keys in key grooves through a specified interval. CONSTITUTION:The is constituted of a taper key device which has taper keys 1a, which are provided as circumferential displacement preventive means between the inner and outer shafts 2 and 3 and the sides of which are tapered in an axial direction, and key grooves (not shown in the Figure), which store these taper keys 1a at a specified interval. Hereby, the taper keys 1a can be stored at a specified interval in the key grooves, and it is unnecessary to require the accuracy in assembly work, and the prevention of the circumferential displacement between the inner rod and the outer cylinder can be done easily. |
