Abstract: To provide the drum brake device enables the assembly of the strut assembly (20) while the brake shoes (11, 12) are being positioned on the backing plate (10). In the drum brake device equipped with the incremental type automatic shoe clearance adjustment apparatus, the strut assembly (20) is structured to be assembled from the opposite direction of the backing plate (10) relative to the pair of brake shoes (11, 12).

Abstract: To provide the mechanical brake actuator enabling to downsize the device and to reduce the manufacturing costs of the parts. The mechanical brake actuator comprises the strut (23) which engages with one brake shoe (12) and has two facing plates (23b) with a strut-bridge (23a) connecting therebetween and the plate-like brake lever (24) which engages with the other brake shoe (13). The brake lever (24) is retained in the space (23c) between the facing strut plates and is pivotally supported on the strut (23), and the inner cable (41) of the brake cable (40) connected to the free end (24e) of the brake lever (24) via the connecting pin (43). The mechanical brake actuator which is operated by pulling the inner cable (41) comprises the clip (30), which attaches to the strut-bridge (23a) and restricts the rotation of the brake lever (24) in the cable releasing direction.

Abstract: A brake cable connecting apparatus that prevents a connecting pin from falling out, and whereby it is unnecessary to adjust the insertion depth of the connecting pin. The brake cable connecting apparatus comprises a regulating projection in the strut to prevent over-insertion of a connecting pin. A cable connecting groove is formed in the plate-like brake lever and is supported on the strut by the two facing surface walls. Two resilient members are deformed to allow the connecting pin to move into a cable connecting groove if an inner cable is pulled to insert the connecting pin laterally bridged between two facing plates of the clevis of the brake cable. Further, a cable disengagement restriction portion prevents passage of the connecting pin if the connecting pin may potentially fall out from the cable connecting groove.

Abstract: A brake cable connecting apparatus ensures prevention of brake cable disengagement by a simple structure that offers simple and accurate assemblability. The brake cable connecting apparatus comprises the strut 23 engaging with the brake shoe 12 and the plate-like brake lever engaging with the brake shoe 13. The proximal portion 24a of the brake lever 24 is pivotally positioned in the wider space 23c formed between the two facing surface walls of the strut 23. The cable end 42 of the brake cable 40 is connected with the free end 24e of the brake lever 24 by the connecting pin 43. The inner cable 41 is operated to effectuate braking, and the projection 24g of the free end 24e interferes with the resilient stopper 33 of the resilient member 30 mounted on the strut 23 and is positioned on the rotating trajection of the brake lever 24.

Abstract: The component mounting apparatus includes a component delivery unit, a chuck (13) provided on the component delivery unit, a component transfer unit (19) for receiving a component held by the chuck (13), and a head (20) for receiving the component held by the component transfer unit (19). The head (20) includes a main head body (80), a vertically moving mechanism (81) for the main head body (80), insertion nails (68) provided at a bottom portion of the main head body (80), an opening/closing mechanism (82) for the insertion nails (68), and a turning mechanism (83) for moving the insertion nails (68) in forward and backward directions. A cam plate (84) constituting the turning mechanism (83) is mounted detachably on the main head body (80).
