Claims

[Scope of utility model registration request]

In a motor-directly connected reciprocating pump in which a reciprocating piston rod is connected to the output shaft of a motor via a cam, the piston rod is connected to the piston rod via a spring that urges the piston rod toward the cam and a connecting arm. A connecting guide member, a convex member that can come into contact with an end face of the guide member and restricts movement of the piston rod toward the cam, a switch that controls the operation of the motor, and the switch. It has a contact to be operated, and a handle that rotates integrally with the convex member to operate the contact, and the contact is arranged such that the motor is activated when the rotation angle exceeds a first rotation angle of the handle. The contact portion of the handle with the contactor is configured to be operated, and the guide is configured such that the piston rod is in a position where it can follow the movement of the cam when the rotation angle exceeds a second rotation angle that is larger than the first rotation angle. A starting device for a reciprocating pump directly coupled to a motor, characterized in that the shape of a contact portion between the member and the convex member is defined.
