    • In a rodless cylinder having a piston fitted in a cylinder body for reciprocating movement therein, and a moving member to be moved back and forth along the cylinder body in synchronism with the piston, there is provided a piping and wiring lead-out mechanism which permits the orientation in an arbitrary direction of not only the pipes of operating fluid pressure to and from pressure chambers of the cylinder but also of the lead wires of a piston position sensor switch. For these purposes, ports are opened on the lateral side, outer end and lower side of each of end plates provided at the opposite ends of the cylinder body to supply operating fluid pressure separately to a pair of pressure chambers in the cylinder. The ports to one pressure chamber are communicated with each other through passages provided in the end plate and cylinder body, while a groove is provided along an outer surface of the cylinder body for mounting a switch or switches thereon. A wire lead-out member with a plural number of wire lead-out holes is relocatably fixed in an arbitrary position in the longitudinal direction of the groove.

    • In the expander (50) in a drum brake, when the brake is activated, the sleeve (56) is extended in the lateral directions in the drawing by the wedge (52) inserted within the housing (51), and the shoe engaged with the clip (58) is swung to press the lining (23) against the drum, and friction braking is performed. When the lining (23) wears away and the amount of movement of the sleeve (56) increases, the sleeve (56) is rotated by reciprocal action with a drive ring (62) that is engaged with the periphery of the sleeve and, thereby, the pressing screw (57) screwed thereon comes out by the amount of the increase of movement (the amount of wear on the lining). A flat surface (56c) is formed on the periphery of the sleeve and the detecting head (80) of the displacement detection apparatus detects the rotation of the sleeve (56).
