A method of integrally molding a member to be molded onto a portion of a rigid member, which method is applied to manufacture of a connecting rod used in a crank device of a wiper system in a motor vehicle, for example. In this method of molding, a portion to be positioned is formed in the rigid member, a portion of the rigid member is inserted into a cavity for molding the member to be molded in such a manner that the portion to be positioned is exposed in the cavity, positioning members linearly movably provided in this cavity are engaged with this portion to be positioned to effect positioning, the positioning members are retracted to the outside of the portion to be positioned after the positioning, and thereafter, a molding material is poured into the cavity to mold the member to be molded. The rigid member has a mounting hole integrally molded therein with the resinous member to be molded, slits are provided on the inner peripheral surface of the member to be molded, and the mounting hole formed such that the inner diameters of portions of the mounting hole as opposed to said slits are decreased.
