Abstract

A hydraulic actuation device includes a case; an oil passage provided in the case; and a support member provided in the case and configured to support a supported member. The oil passage includes an opening portion that allows the oil passage to communicate with a space inside the case, the support member is inserted into the opening portion, and a communication between the oil passage and the space inside the case is blocked by the support member.

First claim

The invention claimed is:

1. A hydraulic actuation device comprising:
a case;
an oil passage provided in the case; and
a support member provided in the case and configured to support a supported member, wherein
the oil passage includes an opening portion that allows the oil passage to communicate with a space inside the case,
the support member is inserted into the opening portion, and
a communication between the oil passage and the space inside the case is blocked by the support member.

2. The hydraulic actuation device according to claim 1 , wherein
the support member is fixed to the case by a fastening member in a state where a pressing force along a direction in which the support member is inserted into the opening portion of the oil passage is applied.

3. The hydraulic actuation device according to claim 1 , wherein
the oil passage is a lubricating oil passage for supplying lubricating oil.

4. The hydraulic actuation device according to claim 1 , wherein
the hydraulic actuation device is a continuously variable transmission,
the continuously variable transmission includes
a pair of pulleys, and
an endless annular member wound around the pair of pulleys,

the supported member is a guide member that guides the endless annular member, and
the support member supports the guide member.

5. The hydraulic actuation device according to claim 1 , wherein
the support member has a bottomed tubular shape,
a through hole penetrating a side wall of the support member is formed in the side wall,
the support member is inserted into the opening portion of the oil passage from an opening end side, and the through hole communicates with the oil passage, and
oil in the oil passage flows into an internal space of the support member from any one of an opening end and the through hole, and then is discharged to the oil passage from the other of the opening end and the through hole.
