A joining link, a strut, and first and second expansion levers constitute an expansion and contraction device. At the time of the braking, the proximal end portion of both of the expansion levers are mutually pressed from the opposite sides by first and second pressing members constituting a driving device. The reaction due to the braking is offset by the joining link portion, whereby a large force is not applied to the back plate or the like.

In an anti-skid control system for a motor vehicle, brake fluid pressure reduction-control mode and brake fluid pressure buildup-control mode occurs cyclically; in the reduction-control mode, reduction of the brake fluid pressure is started on the basis of detection of an abrupt drop in wheel speed which occurs when the wheel is braked; and in buildup-control mode, a valve is repetitively opened and closed so that brake fluid pressure buildup and holding operations are performed alternatley and repetitively, whereby the brake fluid pressure is caused to build up gradually. The length of time period for the first buildup operation in the buildup-control mode is determined on the basis of variation in the wheel speed occurring between a low peak point and a high peak point; and the length of time period for at least one of each pressure holding operation and each of the second and succeeding pressure buildup operations in the abovementioned buildup-control mode, is determined on the basis of variation in the wheel speed occurring immediately before the pressure holding or buildup operation is started.

An operating apparatus 1100 of a brake apparatus 1001 for restricting rotation of a brake drum 1003 including an operating lever 1112 and an operation restricting portion 1120 is provided. The operating lever 1112 is supported to be able to operate in a movable range. The movable range includes: a brake release mode permitting rotation of the brake drum 1003 both in regular rotation and reverse rotation; and an auxiliary brake mode restricting only reverse rotation of the brake drum. The operating lever 1112 is urged in a direction reaching the auxiliary brake mode from the brake release mode in a normal state. The operation restricting portion 1120 restricts a movement of the operating lever 1112 reaching the auxiliary brake mode by being brought into contact with the operating lever 1112 in the brake release mode.

The sheet-like rubber forming device has a die body which has an opening having a predetermined cross sectional shape, and a variable die lip which is arranged in a front side of the die body and can change the height of the opening. The variable die lip is constructed by a first movable body and a second movable body. The die lip control unit controls the variable die lip so as to drive the first movable body in an opening direction from a state in which the first movable body and the second movable body are closed when the forming is started, hold the positions of the first movable body and the second movable body after reaching a predetermined height, and drive the second movable body in a closing direction when the forming is finished.

A pipe-end-connecting joint comprisse a nipple 1 inserted in the pipe end, a holder 2 for tightening the outer circumference of the pipe end, and an elastic packing 3 divided into half parts and attached in the holder 2. The nipple 1 includes a tubular portion 11 provided in one longitudinal end side thereof so as to be inserted in the pipe end, a connection portion 12 provided in the other longitudinal end side thereof so as to be connected to another joint, and a flange portion 13 provided in a longitudinal intermediate portion thereof so as to protrude outward. The holder 2 is divided longitudinally into two split parts 2A and 2B so that each of the two split parts 2A and 2B has an semicircularly formed inner circumferential surface 21, and each of the two split parts 2A and 2B has one longitudinal end side in which one of the half parts of the elastic packing is mounted, and has the other longitudinal end side in which a ring-like groove 23 is formed so as to be fitted to the flange portion 13, and further has a longitudinally intermediate portion between the one and the other longitudinal end sides in which a spiral corrugated portion 22 is formed along the outer circumferential surface of the pipe P, the spiral corrugated portion 22 having a spiral protruding portion 24 an inner diameter of which is smaller than an outer diameter of a trough portion r of the pipe P, the two split parts 2A and 2B having holes for insertion of connection bolts.
