An actuator control device performs a reception process in which designations of a minimum operation amount and maximum operation amount of an operation unit for driving an actuator, and a maximum driving speed which is the actuator driving speed corresponding to the maximum operation amount are received. It also performs a determination process in which a function representing a characteristic line that links a first point, which corresponds to the minimum operation amount and the driving speed of 0, and a second point, which corresponds to the maximum operation amount and the maximum driving speed, is stored in a storage unit as a drive control characteristic and a drive control process in which, in response to operation of the operation unit, the actuator is driven at a driving speed corresponding to the operation amount specified by the drive control characteristic stored in the storage unit.

A motorcycle clutch assist device including a spring arm arranged for rotation or pivoting inside a housing, a biasing device coupled at one end thereof to an axle of the spring arm and at an opposite end thereof to a spring adaptor, and a shaft, one end of which is fixed to the spring arm and an opposite end of which is fixable to the clutch handle, such that the clutch handle rotates about a central longitudinal axis of the shaft and squeezing the clutch handle transfers torque to the spring arm via the shaft, wherein when the biasing device is aligned with the central longitudinal axis no torque is applied by the biasing device, and squeezing the clutch handle causes the biasing device to move past the central longitudinal axis so that the biasing device applies an auxiliary torque to torque applied by squeezing the clutch handle.

A pedal holding device includes: a four-bar linkage including four links and four joints that connect the four links. Two of the four joints serve as two fixed joints that are provided in a main body of the pedal holding device. One of the four links, which is not connected to the two fixed joints, serves as an intermediate link that is provided with a pedal, such that the pedal is not pivotable relative to the intermediate link. One of four internal angles each defined by corresponding adjacent two of the four links becomes not smaller than 180 at at least one moment in a period of movement of the pedal from its rearward end position to its forward end position. Non-adjacent two of the four links intersect with each other apparently when the pedal is positioned in one of the forward end position and the rearward end position.

The present invention relates to an arrangement (1) for assisting a parking brake (10), which parking brake (10) comprises a brake lever (12) which is supported in a carrier device (14) such that it is pivotable between a release position and a locking position and is able to be coupled to a braking system by means of a transmission means. The arrangement (1) comprises a lifting element (20) with an energy storage unit (22), which is operatively connected to the brake lever (12). The operative connection comprises a redirecting element (30) which is supported in a way pivotable about a pivot axis (32) and is arranged in such a way that the redirecting element couples the lifting element (20) to the brake lever (12).

A work vehicle (1) according to an aspect of the present invention is configured to shift, in a transmission unit (17), a speed of a driving force from an engine (5) mounted on a traveling body (2) and to transfer the shifted driving force to a traveling unit (3, 4) and a work unit (70). The work vehicle (1) includes: a mode shift switch (303) that is configured to shift a maximum vehicle speed by the traveling unit (3, 4) or a maximum number of revolutions of the engine (5), the maximum vehicle speed and the maximum number of revolutions being set for each of a plurality of modes; and a work unit operation lever (51) that is configured to be used for operating the work unit (70). The work unit operation lever (51) is provided with the mode shift switch (303).
