Patent ID: 7293317

Claim:
A holding device for a cleaning wiper comprising: a handle; and a support member pivotally connected to a front end of the handle and configured to support a cleaning wiper, the support member having a pivot axis oriented in a direction crossing a shaft axis of the handle, wherein the support member has sliding surfaces that are formed at a predetermined normal distance from the pivot axis and recesses that are formed toward the pivot axis from the sliding surfaces, the sliding surfaces and the recesses alternating with each other about the pivot axis, the handle has a locking member with a locking projection capable of engaging in the recesses, the locking member being movable along the shaft axis inside the handle, the locking member being provided along with a biasing member configured to apply a biasing force to the locking member toward the recesses and an operating member configured to move the locking member in a direction opposite to the biasing force of the biasing member, the operating member is disposed at the front end of the handle in the vicinity of the pivot axis and is a push button that is externally exposed on an outer periphery of the handle and movable in a direction crossing the shaft axis, the locking member has an inclined sliding surface inclined to both a direction along which the push button is to be pushed and a direction along which the locking member is movable, wherein a sliding component force acting on the inclined sliding surface as the push button is pushed permits the locking member to move against the biasing force of the biasing member, and wherein the locking projection protrudes from the inclined sliding surface.
