Abstract: Provided is a biological signal measurement device capable of suppressing an influence of noise derived from a body motion of a test subject on a biological signal measurement result. The biological signal measurement device includes a placement portion on which a test subject is placed, one or more measurement sensors configured to measure a biological signal regarding the test subject, and a sensor holder configured to hold the measurement sensors. The placement portion has a recess. At least a part of the measurement sensor is arranged inside of the recess of the placement portion. The sensor holder and the measurement sensors are arranged to be physically separated from the placement portion without coming into contact with the placement portion.

Abstract: A leaning vehicle includes a caliper and an electric motor supported at a same position in a vehicle body frame.

Abstract: A saddle riding type vehicle includes left and right front wheels that unlock a linkage more surely when the vehicle starts. The vehicle includes a linkage that connects the left and right front wheels to a vehicle body frame, a lock that locks or unlocks the linkage, a lock controller that controls the lock, a wheel speed sensor that detects a vehicle speed, and a vehicle speed change rate obtainer that obtains a vehicle speed change rate. The lock controller unlocks the linkage via the lock if the linkage is locked by the lock and at least one of the vehicle speed and the vehicle speed change rate satisfies an unlocking condition.

Abstract: A saddle riding type vehicle that ensures little or no difference between an actual state of the vehicle and a state of the vehicle recognized by the rider includes a vehicle body frame, a pair of front wheels, a linkage, a lock, a controller, and a notifier. The linkage connects the pair of front wheels to the vehicle body frame. The lock locks the linkage by preventing operation of the linkage and unlocks the linkage by allowing the linkage to operate. The controller controls locking and unlocking of the linkage by the lock. The notifier notifies that the linkage is locked when relative displacement between the pair of front wheels in the vertical direction exceeds a prescribed range.

Abstract: A saddle riding type vehicle includes a linkage, a lock, a controller, and an operator and prevents operation of a linkage upon fulfillment of a prescribed condition and allows the rider's intention to be more easily and accurately reflected in the control of the vehicle. The linkage connects a pair of front wheels to a vehicle body frame. The lock locks the linkage by preventing operation of the linkage and unlocks the linkage by allowing the linkage to operate. The operator continues to output an operation signal to the controller while an operation is input by the rider. The controller controls the lock to lock the linkage if the operation signal is input upon fulfillment of a locking condition that allows the linkage to be locked.

Abstract: A suspension device includes a main body, and a stroke locking mechanism that locks expansion/contraction of the main body. The stroke locking mechanism includes: a tube member coupled to one of a vehicle body and a vehicle wheel; a partition wall body fixed inside the tube member so as to divide an interior of the tube member into a first chamber and a second chamber; a flow passage that connects the first chamber to the second chamber; a valve that cuts off the flow passage during stroke locking; and a shaft member coupled to the other of the vehicle body and the vehicle wheel and inserted into the first chamber to be capable of advancing and retreating. The first chamber is filled with a working fluid, and the working fluid is stored in the second chamber so as to form a reservoir portion.
