[Problem] To provide a hollow operating lever that is easily manufactured with good operability. [Solution] A hollow operating lever (4), which is formed in such a manner that end portions (W1 and W2) of a flat plate-shaped workpiece (W) are joined to each other at a joint (31) and thus is rotatably provided with respect to a support shaft (3), is characterized by including: a first wall (10) that is an operation surface side on which rotational force (F) acts to rotate; a pair of second walls (20) that are provided with coaxial holes (21) through which the support shaft is inserted, and are bent continuously to both ends of the first wall; and a third wall (30) that is provided to face the first wall (10) and is configured to connect the pair of second walls to each other through the joint.

A hybrid vehicle system facilitates operator control over electric power generation and use. The system features a motor/generator that can be mounted to an output of a transmission of the vehicle.

A work vehicle including a floor, a forward pedal arm, a reverse pedal arm, a forward rotation shaft, and a reverse rotation shaft. The floor has a first insertion hole and a second insertion hole. The forward pedal arm is placed in the first insertion hole and provided with a forward pedal. The reverse pedal arm is placed in the second insertion hole and provided with a reverse pedal. The forward rotation shaft serves as a rotation shaft of the forward pedal arm, and is oriented so that an outer end thereof is directed toward the rear of a vehicle body of the work vehicle. The reverse rotation shaft serves as a rotation shaft of the reverse pedal arm, and is oriented so that an outer end thereof is directed toward the rear of the vehicle body.

A work vehicle including a floor (108), a forward pedal arm (41), a reverse pedal arm (51), a forward rotation shaft (42), and a reverse rotation shaft (52). The floor has a first insertion hole (108a) and a second insertion hole (108b). The forward pedal arm is placed in the first insertion hole and provided with a forward pedal (15). The reverse pedal arm is placed in the second insertion hole and provided with a reverse pedal (16). The forward rotation shaft serves as a rotation shaft of the forward pedal arm, and is oriented so that an outer end thereof is directed toward the rear of a vehicle body of the work vehicle. The reverse rotation shaft serves as a rotation shaft of the reverse pedal arm, and is oriented so that an outer end thereof is directed toward the rear of the vehicle body.

A bearing member includes: a large-diameter tubular portion having an external diameter larger than a diameter of a mounting hole formed in a pedal arm and having a cylindrical inner peripheral face; a small-diameter tubular portion formed continuously with the large-diameter tubular portion, having a cylindrical outer peripheral face with a diameter smaller than that of the mounting hole, and having the cylindrical inner peripheral face; and a thin-wall tubular portion formed continuously with the small-diameter tubular portion, having an inner diameter larger than a diameter of the cylindrical inner peripheral face, and having the cylindrical outer peripheral face, and in a condition that the bearing member is inserted into the mounting hole such that the thin-wall tubular portion is protected, and the thin-wall tubular portion is swaged, the mounting hole is held between a swaged portion bulged radially outward and the large-diameter tubular portion.

An electrical-mechanical brake apparatus includes a bracket and a pedal arm supported by the bracket. The bracket has a cam surface. An arm extends from the pivot arm to a follower. As the pedal arm moves toward the bracket, the follower moves along the cam surface, compressing the cam bias for simulating the feel of a purely mechanical brake system. In certain embodiments, the earn body rotates while in others the cam follower rotates.
