摘要： PURPOSE:To make the quick engagement and disengagement operations of a dog clutch possible by a method wherein a means for accelerating a movable dog in the direction out of the position in a transitional stage, in which the retention of the neutral state of the dog clutch is released, is provided. CONSTITUTION:When a driver 42 is pivoted, a follower 32 is shifted axially in a straight line within an output shaft 12 in order to shift a clutch 21 through a pin 29 in the rectilinear direction. At the neutral position, balls 52 engage the output shaft 12 with the follower 32 in order to display the detent function. However, when the follower 32 starts to shift itself in respect to the output shaft 12, the forces acting on balls 51 normal to the axis line energize the follower 32 quickly in the direction of the axis line in cooperation with the slant face of the output shaft 12, due to the energizing force of a spring 56 acting through a ball 55 to the balls 51. Consequently, the clutch 21 is quickly brought into engagement with transmission elements loosely fitted onto the output shaft 12.

摘要： PURPOSE: To prevent a key, transmitting the rotary force between a bushing of impeller and a pump drive shaft, from wear by such a special construction that the relative motion between the bushing and shaft is canceled.
CONSTITUTION: A pump drive shaft 14 is provided with a key seat 72 cut with a plane in parallel with the tangential and axial lines of the shaft 14, and a bushing 52 is, in its internal surface, provided with an arc-shaped concave 74 having a smaller radius than the drive shaft 14 stretched long in the axial direction. Between the key seat 72 and concave 74 is fitted a tangential key 70 long in axial direction and half-moon shaped in profile, whose radius is such as to slide on the curvature of the concave 74 closely. Accordingly, when the impeller, not illustrated, rotates, the key 70 will bite into the gap between the key seat 72 and concave 74 as a wedge to couple bushing 52 and shaft 14 firmly. Consequently, water will not flow into or out of the gap between bushing 52 and shaft 14, that is likely when impeller rotates in a conventional arrangement, and the wear owing to sand or mud included in the water can be remarkably reduced.
