Oil pressure control device

An oil pressure control device, comprising:

• a first body part having a first oil passage inside and having a first recess communicating with the first oil passage from a first opening on an outer surface;
• a second body part having a second oil passage inside and having a second recess communicating with the second oil passage from a second opening on an outer surface;
• and
• a columnar valve member,
• wherein the first body part and the second body part are arranged such that the first opening and the second opening are opposed to each other and the valve member is housed in a housing space formed by the first recess and the second recess,
• wherein the valve member comprises:
• a cylindrical sleeve comprising a first end part which is an end part having a third opening communicating with the first oil passage, a second end part which is an end part having a fourth opening communicating with the second oil passage opposite to the first end part, and a hollow part between the first end part and the second end part;
• a valve body arranged in the hollow part on a side of the second end part to open and close a third oil passage forming the hollow part on the side of the second end part;
• a movable member arranged in the hollow part on a side of the first end part and housed to be movable along the hollow part, and having a pressure receiving surface on the side of the first end part to receive an oil pressure from the first oil passage and having a contact part on the side of the second end part to contact the valve body according to the oil pressure on the pressure receiving surface;
• and
• a detent member arranged between the valve body and the second end part to limit movement of the valve body towards the side of the second end part within a predetermined range.
